What Is Recommended To Minimize Interruptions In Compressions When Using An Aed?

Please purchase the course before starting the lesson. Many times there will be a second person available that can act as a rescuer. The ILCOR emphasizes that cell phones are available everywhere now and most have a built-in speakerphone. Direct the second rescuer to call 911/EMS without leaving the person while you begin CPR.

The second rescuer prepares the AED for use.You begin chest compressions and count the compressions out loud.The second rescuer applies the AED pads.The second rescuer opens the person’s airway and gives rescue breaths.Switch roles after every five cycles of compressions and breaths. One cycle consists of 30 compressions and two breaths for adults.Be sure that between each compression you completely stop pressing on the chest and allow the chest wall to return to its natural position. Leaning or resting on the chest between compressions can keep the heart from refilling in between each compression and make CPR less effective. Rescuers who become tired may tend to lean on the chest more during compressions; switching roles helps rescuers perform high-quality compressions.Quickly switch between roles to minimize interruptions in delivering chest compressions.When the AED is connected, minimize interruptions of CPR by switching rescuers while the AED analyzes the heart rhythm. If a shock is indicated, minimize interruptions in CPR by resuming CPR as soon as possible beginning with chest compressions.

• Out-of-hospital cardiac arrest (OHCA) is one of the leading causes of death in the industrialized world, with an average global incidence of 55 cases per 100,000 person-year ( 1 ).
• OHCA is a major public health problem.
• Every 5 years leading institutions like the European Resuscitation Council (ERC) and the American Heart Association (AHA) publish the resuscitation guidelines, with treatment recommendations for OHCA based on a comprehensive review of the available scientific evidence.

Despite the therapeutical advances introduced by the guidelines over the years survival remains dismally low, with average survival rates to hospital discharge below 6% for all cases, and below 12% for patients presenting initial shockable rhythms ( 1 ).

Quality cardiopulmonary resuscitation (CPR) is critical for the survival of the patient suffering OHCA. During CPR chest compressions are delivered in the center of the chest, with target depths of 5–6 cm, rates of 100–120 min −1 and allowing complete chest recoil. Since the 2005 update, resuscitation guidelines recommend a sequence of 30 compressions followed by a 5-s interruption for 2 ventilations, the standard 30:2 CPR.

During CPR chest compressions are interrupted for various reasons including rescue breaths, rhythm analysis, pulse-checks and defibrillation. These interruptions decrease coronary and cerebral blood flow and have been associated with decreased survival both in animals and humans ( 2 – 4 ).

Rescue breaths are critical in respiratory arrest, where hypoxia leads to cardiac arrest. In nonasphyxial arrest arterial blood is saturated with oxygen for several minutes, and rescue breaths may not be essential for survival ( 2, 3 ). During the circulatory phase of the arrest (4–10 min from arrest), the generation of adequate cerebral and coronary perfusion by chest compressions maybe crucial for the survival of the patient ( 5 ).

This observation leads to the introduction of the concept continuous chest compressions (CCC), i.e., CPR without pauses for ventilation. Researchers from the University of Arizona in cooperation with the Tucson Fire Department instituted the basis of cardiocerebral resuscitation (CCR).

CCR is an alternative to the standard resuscitation protocol that emphasizes the adoption of CCC. They proposed a bundle of treatment changes including 200 uninterrupted preshock chest compressions, rhythm analysis with a single shock, 200 immediate postshock chest compressions before pulse check or rhythm reanalysis, early administration of epinephrine and delayed endotracheal intubation.

They first introduced CCR in 2005 in selected emergency medical services (EMS) ( 6 – 8 ), progressing up to larger observational cohort studies and prospective studies with historical controls ( 9 – 11 ). In their largest study involving 2,460 patients ( 10 ) the adoption of CCR in EMS systems almost tripled overall survival to hospital discharge from 3.8% to 9.1%, an effect observed also in patients with witnessed ventricular fibrillation (from 11.9% to 28.4%).

The increase in survival rates was due to a multiplicity of factors associated to the bundle of treatment changes introduced by CCR, and may have also been due to improved CPR quality. Unfortunately CPR quality data was not recorded in these studies. One of the advantages of CCC is the increase of bystander CPR rates, because many bystanders are unwilling to give mouth-to-mouth rescue breathing ( 12 ).

However, once CPR is initiated by the bystander the advantages of CCC over standard CPR are unclear. Several Japanese studies have investigated the effect on survival of both types of CPR. These observational studies ranged from the initial local retrospective studies of under 5,000 cases ( 13, 14 ), to nationwide prospective studies of about 50,000 cases ( 15, 16 ).

• Bystander CPR increased survival when compared to no CPR, however no significant differences in survival with good neurological outcome were found between standard and compression only CPR.
• In fact, for non-cardiac arrests standard CPR was superior to compression only CPR.
• For arrests of cardiac origin both types of bystander CPR had comparable survival rates—6.4% vs.7.1%—when CPR was delivered before 15 min, but survival was significantly higher for standard CPR—2.0% vs.1.3%—when CPR was initiated after 15 min.

Increasing bystander CPR rates through the use of simplified protocols such as CCC may lead to higher survival rates ( 12 ). However, the benefits of CCC over the standard 30:2 protocol for CPR delivered by EMS services are unclear, so current ERC guidelines still recommend 30:2 CPR ( 17, 18 ).

The bundle of therapies introduced in the studies advocating the use of CCR result in many confounders that mask the contribution to survival of individual therapies such as CCC. The contribution to survival of CCC is further obscured by the absence of CPR quality data in these observational studies with historical controls.

The study by Nichol et al. ( 19 ) finally sheds light on whether CCC as compared with the standard 30:2 protocol improves survival when CPR is delivered by EMS providers. The study was designed as a crossover cluster-randomized control trial (RCT) of non-trauma related cardiac arrest treated by EMS ( 20 ), and was conducted by the resuscitation outcomes consortium (ROC).

The primary outcome was the rate of survival to hospital discharge, with neurologic function at discharge as secondary outcome. The trial involved 114 EMS agencies from 8 ROC sites grouped in 47 clusters during a period of 4 years. The clusters were crossed over twice a year between the two resuscitation strategies, namely CCC (intervention group) or the standard 30:2 protocol (control group), designated as interrupted chest compressions (ICC).

Patients assigned to the CCC group were to receive compressions at a rate of 100 min −1 with positive-pressure ventilations at a rate of 10 min −1, For the patients in the ICC group pauses for two ventilations were to last less than 5 s. In total 12,613 patients were assigned to the intervention group (CCC) and 11,058 to the control group (ICC), and in both cases primary outcome data was available in more than 99.7% of cases.

1. The study sites acquired and reported CPR-quality data measured by the monitor-defibrillators which included variables such as rate, depth or chest compression fraction (CCF).
2. These data was reviewed by an automated algorithm and by the research coordinator to ensure adherence to the treatment protocols, and a per-protocol analysis of the data was then conducted.

The per-protocol analysis based on the automated algorithm included 6,529 and 3,678 patients in the intervention and control groups, respectively. The characteristics of the patients, EMS providers, and hospital treatments were well balanced between the two branches of the trial.

There were of course significant differences in the CPR data related to pauses in chest compressions, with significantly higher CCF (0.83 vs.0.77) and less pauses in compressions (3.8 vs.7.0) in the intervention group. Although significant, these differences were not as large as expected because rescuers did not strictly adhere to the treatment protocol.

In the per-protocol analysis differences were much larger (0.87 vs.0.73 for CCF, and 2.8 vs.10.3 in number of pauses), but some pretreatment and treatment characteristics were imbalanced, with significantly higher rates of shockable rhythms and prehospital intubations in the control group.

Nichol et al. found no significant differences in survival to hospital discharge between the CCC and ICC groups, with survival rates of 9.0% and 9.7%, respectively. Differences in survival with good neurological outcome, defined as score of three or less in the modified Rankin scale, were also not significant with values of 7.0% in the intervention and 7.7% in the control group.

In the per-protocol analysis, which ensured adherence to the treatment protocol, survival was significantly higher in the control group, with rates of 9.6% and 7.6% for the ICC and CCC groups, respectively. However, when adjusted for pretreatment confounders differences in survival rates in the per-protocol analysis were no longer significant.

1. Two key factors explain these results.
2. First, by conducting a large scale RCT Nichol et al.
3. Were able to isolate the effect on survival of pauses for two rescue breaths, particularly in the per-protocol analysis.
4. In contrast, previous studies introduced a myriad of changes in the treatment protocol which obscured the contribution to survival of individual treatment changes.

Second, CPR quality in both branches of the trial was close to optimal, with rates around 110 min −1, depths close to 50 mm and CCF above 0.7. All these CPR quality variables have been previously shown to influence survival and were not controlled for in the previously cited studies.

1. One of the limitations of the study is the small difference in CCF between the treatment branches.
2. However, when adherence to treatment protocols was checked differences in CCF were larger.
3. The study by Nichol et al.
4. Shows that pauses for two rescue breaths in 30:2 CPR are not detrimental for survival, even when the presumed cause of the arrest is cardiac.

This is particularly so when CPR is delivered in the ranges recommended by the resuscitation guidelines.

Is it recommended to minimize interruptions in CPR for pulse checks?

Conversely, prolonged interruptions in chest compressions are associated with poorer outcomes. Hence, international guidelines recommend minimizing chest compression interruption as part of high‐quality CPR. Compression interruptions are necessary to perform important tasks, such as rhythm checks and pulse checks.

Should you continue compressions while using an AED?

Using an AED: The Step-by-Step Guide AEDs can mean the difference between life and death when sudden cardiac arrest occurs. Before finding yourself in an emergency situation, it’s helpful to become familiar with this powerful device and understand how to effectively use one so you can react confidently in a real-life scenario.

1. Follow along as we explain AED usage in 5 simple steps! Always remember to follow the prompts of your AED as models vary.
2. AEDs are there to help guide you through each step of the process! STEP 1: Turn on the AED.
3. If another bystander has gone to retrieve the AED, perform CPR on the victim until it arrives.

As soon as an AED arrives to the victim, press the “Power” button to turn on the device. From the moment the device is powered on, a voice will begin to guide you and provide directions. STEP 2: Attach the pads to the victim’s chest. AED pads should be applied to a victim’s bare, dry chest.

1. If the chest is wet, use a towel to dry before applying the AED pads.
2. One pad should be applied to the right-side chest beneath the collarbone, and the other should be applied a few inches below the left armpit.
3. Many models will have images on the pads to help you place them in the correct spot.
4. Plug the connector into the AED after attaching the pads (if your model does not come with the connector already attached).

Confirm that no one is touching the victim, then confidently wave your hand over the victim’s body and announce “Everyone clear!”. STEP 3: Stand back for analysis. This is where the AED begins to do its most important work – determining whether the victim’s heart requires a shock.

• It is critical that no one be touching the victim as the AED analyzes.
• If someone is touching the victim, the AED can pick up on that person’s heart rhythm and falsely indicate whether or not a shock is needed.
• STEP 4: Deliver the shock if advised.
• After analyzing, the AED will announce whether a shock is advised.

If a shock is advised, confirm once more that no one is touching the victim and announce “Everyone clear!”. If someone else touches the victim when the shock is delivered, the bystander can be shocked and another medical emergency can occur. Press the shock button (usually an orange or red button) and wait for further instructions.

• If the AED announces that a shock is NOT advised, perform CPR until further help arrives or signs of life are shown.
• STEP 5: Perform CPR and follow further instructions.
• After a shock is delivered, the AED will prompt you to continue performing CPR.
• Immediately begin cycles of 30 compressions and 2 breaths.

The device will then re-analyze and advise if another shock is needed. Continue to follow the AED’s instructions until further help arrives. The Bottom Line AEDs are designed to be user-friendly. However, they can still be intimidating when used in a time-sensitive, high pressure environment.

Which of these actions are appropriate ways to minimize interruptions in chest compression quizlet?

Which of these actions are appropriate ways to minimize interruptions in chest compressions? – Remain in position with the hands a few inches above the patient’s chest during shock delivery.

Should pauses in chest compressions be minimized and should only be taken?

Summary: It is important to avoid any unnecessary pause in chest compressions before and after a defibrillation shock. Pauses should be kept to an absolute minimum, preferably to less than 10 s.

What is the team role to keep track of interruptions in compressions?

The Timer/Recorder team member records the time of interventions and medications and then announces when the next treatment is due. They record the frequency and duration of interruptions in compressions and communicates these to the team leader and the entire team.

What are some special considerations when using an AED?

An AED or Automated External Defibrillator is a portable electronic device that can analyze the heart’s rhythm and can correct the underlying problem for some people who encounter sudden cardiac arrest. A CNA School in Park Ridge, Illinois can provide training on how to properly use an AED and educate future healthcare professionals on how to respond during emergencies.

Environmental Considerations

Do not use an AED near flammable or combustible materials (e.g. gasoline). It is safe to use an AED when the person is lying on a metal surface, but don’t allow the AED pads to contact the metal surface. Do not use an AED if the person is in or near water. Avoid getting the AED wet. It is safe to use AEDs in all weather conditions. If possible, provide a dry environment before using AED. Remove the person’s wet clothing and wipe the chest dry before placing the AED pads.

Person-Specific Considerations

It is safe to use an AED on a pregnant woman. If the person has a pacemaker or ICD, adjust pad placement as necessary to avoid placing the AED pads directly over the device. Healthcare professionals should learn from their healthcare education how to determine if a person uses a pacemaker or ICD. Remove any transdermal medication patches (e.g. nitroglycerin) that you see before using an AED. Wear gloves when removing these patches If the person has thick chest hair that interferes with pad-to-skin contact, quickly shave the areas where the pads will be placed.

What amount of time should BLS providers minimize interruptions during chest compressions?

Ventilation With an Advanced Airway Instead, the compressing rescuer should give continuous chest compressions at a rate of 100 per minute without pauses for ventilation.

How long should CPR be interrupted?

Generally, it is recommended to perform CPR for at least two minutes before assessing the patient’s response. If there is no response after two minutes, then CPR should be continued until medical help arrives or until the patient regains consciousness.

Should you continue CPR while the AED is analyzing the patient’s heart rhythm?

AED Guidelines AEDs (Automatic External Defibrillators), when used swiftly-in the first 3-5 minutes of a person collapsing-have been shown to dramatically increase the survival rate of people suffering from cardiac arrest. An AED will automatically determine the heart rhythm of a pulseless victim and, if the victim is in ventricular fibrillation (v-fib), shock the victim’s heart in an attempt to restore its rhythm to normal.

• When a heart is in v-fib, it is still receiving nerve impulses from the brain.
• These impulses are simply firing so chaotically that the heart cannot produce a “beat;” it cannot expel enough blood to keep the circulatory system (and thus oxygen) flowing through the body.
• Brain cells begin to die after 4-6 minutes of oxygen deprivation.

The heart will continue its uncoordinated twitching until it is no longer receiving electrical impulses from the brain (and thus stops all together), or until the heart is shocked back into a normal rhythm, which is where an AED comes in. An AED stops the heart from its spasm by shocking it.

1. This allows the nerve impulses a chance to resume their normal pattern, which, in turn, allows the heart to resume beating at its normal pace.
2. AEDs can be found in many public areas including most malls, stadiums and airports.
3. They are straightforward and easy to use.
4. Since time is the most important factor in a cardiac emergency, it is important for the general public to understand how to use an AED.

Note: AEDs are NOT for use on trauma patients, children under the age of 1, or victims that HAVE a pulse. Call 911. If you see someone collapse, immediately call 911 and get the medics en route. If there are other people around, choose someone specific and instruct him to call 911 and explain the situation.

This decreases confusion about who should do what and ensures that the call is being placed. Check the victim’s respirations and airway. If someone has collapsed, you should immediately determine whether he or she is breathing. If the victim is breathing, you know that he has pulse. If the victim is not breathing, begin rescue breathing and chest compressions as described in How To Perform CPR.

Locate an AED. If there is an AED nearby, ask a bystander to take over CPR while you apply the AED to the victim. Uninterrupted CPR is an important factor in increasing the recovery rate of cardiac arrest patients. Always ensure that someone is providing CPR for the victim unless the AED machine is actively analyzing or shocking the victim.

1. Attach the AED.
2. First ensure that the adhesive AED pads are attached to a cable, which is plugged into the AED machine.
3. Then bare the victim’s chest and attach the adhesive AED pads in the appropriate locations.
4. The AED should include a diagram (typically on the adhesive pads themselves) indicating where each pad goes.

Always follow the instructions on the AED. Typically the negative pad is placed on the victim’s right upper chest wall (above the nipple and to the right-from the victim’s perspective-of the sternum). The positive electrode is placed on the victim’s left chest/side (axillary line) just below the nipple and pectoral muscle.

Note: CPR should not be interrupted while the adhesive pads are being applied. Turn on the AED. Stop CPR and say, “CLEAR!” Ensure that nobody is touching the victim and push the “analyze” button on the AED machine. The AED will not be able to analyze the victim’s heart rhythm accurately during CPR. Analyze the victim’s heart rhythm.

The AED will automatically analyze the heart rhythm of the victim and inform you, the rescuer, whether shocks are indicated. A shock is only indicated if the victim’s heart is in ventricular fibrillation. If you get a “no shock” message from the AED it can mean one of three things: the victim that you thought was pulseless does indeed have a pulse, the victim has now regained a pulse, or the victim is pulseless but is not in a “shockable” rhythm (i.e.

1. Not ventricular fibrillation).
2. In this case proceed to step 11.
3. Shock the victim.
4. If the AED indicates that a shock is required, make sure that everyone is clear of the victim.
5. Tell everyone assisting you to stay clear of the victim and ensure that you are clear of the victim as well.
6. Then press the shock button on the AED machine to deliver the first shock.

Immediately following the shock, begin CPR for 5 cycles (or approximately 2 minutes). Begin CPR for 2 minutes (5 cycles). Perform CPR for 5 cycles of 30 compressions to 2 breaths. Note: Do not remove the AED pads to perform CPR. Leave them in place. Check the victim’s rhythm.

Use the AED to analyze the victim’s rhythm after 2 minutes of CPR. Revert to step 7. If indicated by the AED, provide the victim with another shock. If the machine gives a “no shock” message after any analysis, check the victim’s pulse and breathing. If a pulse is present, monitor the victim’s airway and provide rescue breathing as needed.

There are many different AED designs, but all are created with simplicity in mind. Many models will audibly instruct the rescuer about exactly what to do during each step of the process (i.e. “stand back” and “check breathing and pulse”). Some will even deliver the shocks automatically.

As long as you understand the general principles behind an AED, you may be able to save someone’s life. Remember: Do NOT use an AED on a trauma patient. Do NOT use an AED on a child under 1 year of age. Do NOT use an AED on a victim with a PULSE. Note: These guidelines are not a substitute for AED training.

Should CPR be regularly interrupted to check for response or breathing?

Minimise Interruptions to Chest Compressions – CPR should not be interrupted to check for response or breathing. ANZCOR places a high priority on minimising interruptions for chest compressions. We seek to achieve this overall objective by balancing it with the practicalities of delivering 2 effective breaths between cycles of chest compressions to the patient without an advanced airway.

How often do you interrupt chest compressions to assess heart rate?

Abstract – Objectives: Most guidelines recommend pausing chest compressions at 2 min intervals to analyze the cardiac rhythm. We conducted a systematic review and meta-analysis to define the optimal interval at which to pause chest compressions in adults for cardiac rhythm analysis in any setting.

1. Methods: We searched PubMed, Embase, and Cochrane databases through January 2, 2015, including human studies addressing any two different intervals of rhythm analysis.
2. GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) methodology evaluated confidence in estimates of effect for evidence pertaining to functional outcome, survival, and return of spontaneous circulation.

Results: Of 1,136 identified papers, nine were included (three RCTs and six observational studies). Quality of evidence for each outcome was very low or low (usually downgraded risk of bias and indirectness). RCTs comparing specific intervals (3 min vs.

Immediate rhythm analysis; 1 vs.2 min; 3 vs.1 min) demonstrated no difference between either arm. Meta-analyses of observational studies demonstrated benefit for a bundled ‘minimally interrupted chest compression’ protocol dictating 200-compression intervals compared with historical controls treated with 1- or 3 min intervals per the 2000 guidelines (OR 1.85, 95% CI 1.27,2.68 for ROSC; OR 2.84, 95% CI 2.12,3.79 for survival to discharge; OR 2.94, 95% CI 1.60, 5.37 for good functional outcome).

Conclusion: There is a paucity of quality evidence to support pausing chest compressions at any singular interval to assess the cardiac rhythm in adults in cardiac arrest in any setting. Very low-quality evidence suggests improved clinical outcomes in patients receiving 200-compression intervals compared with 1- or 3 min intervals.

Which of these actions are appropriate ways to minimize interruptions in chest compression quizlet?

Which of these actions are appropriate ways to minimize interruptions in chest compressions? – Remain in position with the hands a few inches above the patient’s chest during shock delivery.

Should pauses in chest compressions be minimized and should only be taken?

Summary: It is important to avoid any unnecessary pause in chest compressions before and after a defibrillation shock. Pauses should be kept to an absolute minimum, preferably to less than 10 s.

Do ACLS providers must make every effort to minimize any interruptions in chest compressions?

ACLS providers must make every effort to minimize any interruptions in chest compressions. Try to limit interruptions in chest compressions (eg, defibrillation and rhythm analysis) to no longer than 10 seconds, except in extreme circumstances, such as removing the patient from a dangerous environment.
