Module 03
High-Quality CPR
Excellent CPR is the single most important intervention during cardiac arrest.
When to Begin
- Begin CPR immediately when a patient is pulseless.
- If uncertain whether a pulse is present after 5–10 seconds, begin chest compressions.
- Recognize arrest by: unresponsiveness, no normal breathing, agonal respirations, no pulse.
- Agonal gasps are NOT normal breathing — begin CPR immediately.
Compression Quality
- Minimize interruptions in compressions to less than 10 seconds.
- Resume compressions immediately after every rhythm check or defibrillation.
- Aim for the highest possible chest compression fraction (CCF).
- Rotate compressors approximately every 2 minutes to prevent fatigue and maintain quality.
- The CPR Coach's primary responsibility is maintaining CPR quality.
Avoid Excessive Ventilation
- Excessive ventilation increases intrathoracic pressure and decreases cardiac output.
- Deliver breaths without interrupting compressions when using an advanced airway.
- Target ventilation rate: 1 breath every 6 seconds (10 breaths/minute) for patients with a pulse.
Clinical Pearl
Good CPR buys time until the underlying cause can be corrected.
