When Should You Stop CPR? Understanding the Guidelines

Cardiopulmonary resuscitation (CPR) is a critical life-saving skill that sustains blood flow and oxygen delivery to vital organs during a cardiac arrest or respiratory failure. Its prompt and effective application significantly increases the chances of survival. However, equally important is knowing when to begin CPR and when to stop it. While the decision to cease resuscitation efforts can be challenging, it should be based on evidence-based guidelines and the unique circumstances of the situation. This comprehensive guide, informed by recommendations from MyCPR NOW, outlines the conditions and considerations for stopping CPR.

Guidelines for Stopping CPR in Cardiac Arrest

1. Arrival of Advanced Medical Help

The primary objective of CPR is to maintain oxygenation and circulation until emergency medical responders can take over. An automated external defibrillator (AED) can signal the rescuer to stop CPR for rhythm analysis.

• When to Stop: Cease CPR when professionals such as paramedics or emergency medical technicians (EMTs) arrive and assume responsibility for resuscitation.

• Reasoning: Medical responders are trained to provide advanced life support, administer medications, use defibrillators, and perform interventions that extend beyond the capabilities of basic CPR.

2. Return of Spontaneous Circulation (ROSC)

ROSC occurs when the person regains a palpable pulse or other signs of effective circulation.

• Signs of ROSC:

• Spontaneous breathing.

• Movements or reflexes.

• A detectable pulse during assessment.

• Actions:

• Stop CPR but remain vigilant. Monitor the individual closely to ensure their condition stabilizes. Monitoring a person's breathing is crucial to assess their recovery and determine if further intervention is needed.

• Be prepared to resume CPR if their pulse or breathing ceases again.

3. Fatigue or Physical Exhaustion

CPR can be physically demanding, particularly during prolonged resuscitation efforts.

• When to Stop: If the person performing CPR becomes too fatigued to deliver high-quality chest compressions and no replacement is available, it may be necessary to stop.

• Best Practice: Whenever possible, rotate with another trained individual every 2 minutes to maintain the quality of compressions.

4. Obvious Signs of Death

Certain physical signs indicate that resuscitation is no longer viable.

• Signs:

  • Rigor Mortis: Stiffening of the body due to postmortem changes.

  • Livor Mortis: Blood pooling in the lower parts of the body, causing discoloration.

  • Catastrophic Injuries: Injuries that are incompatible with life, such as decapitation or dismemberment.

• Actions: Cease CPR in these situations, as it is unlikely to be effective.

5. Determination by Medical Professionals

Medical professionals may assess the situation and decide to discontinue resuscitation.

• Factors Considered:

• The person’s medical history and preexisting conditions.

• The cause and duration of cardiac arrest.

• The likelihood of a meaningful recovery.

• When to Stop:

• If directed by a medical professional, follow their guidance.

Considerations for Stopping CPR

While the above guidelines provide a framework, the decision to stop CPR should also consider individual and contextual factors.

1. Duration of CPR

The length of time CPR has been performed can influence the likelihood of a successful outcome.

• Extended CPR: Prolonged resuscitation efforts (e.g., 20–30 minutes) without signs of ROSC reduce the chances of survival, but CPR should generally continue until advanced help arrives.

• Context: Certain situations, such as hypothermia or drowning, may warrant prolonged CPR, as individuals can survive under these conditions with extended efforts.

2. Safety of the Rescuer and Bystanders

Your safety and the safety of others should always be a priority during resuscitation. Principles of emergency medicine emphasize the importance of ensuring a safe environment before beginning CPR.

• Unsafe Conditions:

• Fire, smoke, or explosion risks.

• Violent environments.

• Structural instability at the scene.

• Actions: If the environment becomes hazardous, prioritize evacuation and cease CPR if necessary.

3. Family Wishes and Advance Directives

In some cases, the person receiving care may have advance directives, or their family may express specific wishes regarding resuscitation.

• Do-Not-Resuscitate (DNR) Orders:

  • A legal document that specifies the individual’s wish not to undergo CPR.

  • If a valid DNR is presented, CPR should not be initiated or should be stopped.

• Family Input: Respect the family’s wishes when consistent with legal and ethical guidelines.

Supporting Information: Why Timing Matters

Stopping CPR prematurely or continuing it unnecessarily can impact the outcome and emotional burden on all parties involved. Balancing persistence with appropriate cessation ensures compassionate and effective care.

The Importance of High-Quality CPR

High-quality CPR involves delivering chest compressions at the correct depth (2–2.4 inches) and rate (100–120 compressions per minute) while minimizing interruptions.

• Impact of Fatigue: Compressions that are too shallow or slow due to rescuer fatigue can compromise the effectiveness of CPR.

Performing CPR Effectively

Performing CPR effectively requires a combination of proper technique, knowledge, and physical ability. When performing CPR, it’s essential to follow the correct steps and guidelines to ensure the best possible outcome for the victim. Here are some key factors to consider when performing CPR effectively:

• Proper Hand Positioning: Place the heel of one hand on the center of the victim’s chest, just above the nipple line. Place your other hand on top of the first hand, with your fingers interlaced. This positioning helps ensure that the force of your compressions is directed correctly.

• Chest Compressions: Push down on the chest with the heel of your hand to a depth of 2-3 inches. Release the pressure completely between compressions to allow the chest to return to its normal position. Aim for a rate of 100-120 compressions per minute. High-quality chest compressions are crucial for maintaining blood flow during cardiac arrest.

• Rescue Breaths: After every 30 chest compressions, give two rescue breaths. Each breath should last one second and make the victim’s chest rise. This combination of compressions and breaths helps to circulate oxygenated blood to vital organs.

• Continue CPR: Continue performing CPR until emergency medical personnel arrive, the victim shows signs of life, or you are physically unable to continue. Signs of life include normal breathing, movement, or a detectable pulse. If you become too exhausted to maintain effective compressions, it’s important to seek assistance from another trained individual if available.

By adhering to these guidelines, you can maximize the effectiveness of your CPR efforts and improve the chances of a positive outcome for the victim. Remember, high-quality CPR can make a significant difference in a medical emergency, so it’s essential to stay informed and prepared.

Scenarios

1. ROSC During CPR

• Scenario: A person collapses, and CPR is initiated. After several minutes, they start breathing and regain a pulse.

• Actions:

• Stop performing CPR and stop chest compressions.

• Place the person in the recovery position to maintain an open airway.

• Monitor vital signs until EMS arrives.

2. Arrival of Emergency Medical Personnel

• Scenario: A bystander begins victim CPR on a person experiencing cardiac arrest. EMS arrives after 8 minutes.

• Actions: Cease CPR immediately and provide EMS personnel with relevant information about the event and the actions taken.

3. Unsafe Conditions

• Scenario: During an active shooter situation, CPR is being performed. The area becomes unsafe due to the proximity of danger.

• Actions: Evacuate to safety and stop CPR if necessary.
