As a healthcare professional with extensive experience in emergency medicine, I am often asked about the proper technique for performing Cardiopulmonary Resuscitation (CPR). CPR is a critical skill that can save lives in emergency situations where a person’s heart has stopped beating or they are not breathing effectively.

The question of whether CPR involves 15 compressions to 2 breaths is a common one, and it's important to clarify this to ensure that individuals are performing CPR correctly. The ratio of compressions to breaths can vary depending on the circumstances and the number of rescuers present.

According to the latest guidelines from the American Heart Association, for adult CPR, the recommended ratio is 30 compressions to 2 breaths when a single rescuer is performing CPR. This means that the rescuer should perform 30 chest compressions and then give 2 rescue breaths. The compression rate should be between 100-120 compressions per minute, and the depth of each compression should be about 2 inches (5 cm). It's crucial to allow the chest to fully recoil after each compression to ensure blood flow.

However, if there are multiple rescuers present, the ratio changes to 15 compressions to 2 breaths. This is because having more people available allows for a more efficient distribution of tasks, with one person focusing on providing breaths while the others continue with compressions.

It's important to note that these guidelines are based on the best available evidence and are designed to maximize the chances of survival for the victim. The focus of CPR should be on high-quality chest compressions, as they are the most critical component of CPR. Rescue breaths are important, but they should not interrupt the flow of compressions.

In addition to the compression-to-ventilation ratio, there are other key aspects to performing CPR effectively:


1. Check for responsiveness: Before starting CPR, always check if the person is responsive and breathing normally.

2. Call for help: If the person is unresponsive and not breathing, call emergency services immediately.

3. Position the victim: Lay the person flat on their back on a firm surface.

4. Start compressions: Place the heel of one hand in the center of the chest and the other hand on top. Keep your arms straight and your shoulders directly above your hands.

5. Minimize interruptions: Try to avoid any unnecessary pauses in CPR, as this can reduce the effectiveness of the procedure.

6. Continuous assessment: Continuously assess the victim's response to CPR and adjust your actions as necessary.

Remember, CPR is a life-saving technique that should be performed with the utmost care and attention to detail. It is always recommended to take a certified CPR course to learn the proper techniques and stay updated on the latest guidelines.
