Is CPR a combination of chest compression and rescue breaths?

Yes, CPR (Cardiopulmonary resuscitation) is a combination of chest compressions and rescue breaths. It is a life-saving procedure used to restore blood circulation and breathing when a person's heart has stopped beating or is not functioning effectively.

During CPR, chest compressions are performed to mimic the pumping action of the heart, helping to circulate oxygenated blood throughout the body. Rescue breaths, also known as mouth-to-mouth resuscitation, are given to provide oxygen to the person's lungs.

The recommended ratio of chest compressions to rescue breaths in CPR varies depending on the guidelines and protocols followed by different organizations. For example, according to the American Heart Association (AHA), the recommended ratio for adults is 30 compressions to 2 breaths, while for children and infants, it is 15 compressions to 2 breaths.

Here's a simplified overview of the steps involved in performing CPR:

1. Check for responsiveness: Determine if the person is responsive by gently shaking and calling out to them.

2. Call for help: If the person is unresponsive, immediately call for emergency medical assistance.

3. Begin chest compressions: Position the person on their back on a firm, flat surface. Place the heel of one hand on the center of the person's chest, just below the nipples. Place your other hand over the first, interlacing your fingers. Perform chest compressions by pushing down firmly and evenly at a rate of approximately 100 to 120 compressions per minute.

4. Provide rescue breaths: After every 30 compressions, give two rescue breaths. Pinch the person's nose closed and cover their mouth completely with your mouth, ensuring a tight seal. Blow until their chest visibly rises, then remove your mouth and allow them to exhale before providing the next breath.

5. Continue CPR: Continue alternating between chest compressions and rescue breaths until the person starts showing signs of life, such as breathing, coughing, or moving, or until emergency medical personnel arrive and take over.

Remember that performing CPR effectively requires proper training and regular practice. If you are not trained in CPR, consider enrolling in a certified CPR course to acquire the knowledge and skills necessary to respond effectively in life-threatening situations.
