As an expert in emergency medical response, it's important to understand the nuances of when and how to perform CPR. If a patient is unresponsive but has a pulse, it indicates that their heart is still beating, but they are not breathing. In this case, you should provide rescue breathing without chest compressions. Here's the step-by-step approach: 1. Ensure safety: Make sure the scene is safe for both you and the patient. 2. Call for help: If you're alone, call emergency services immediately. 3. Open the airway: Tilt the patient's head back and lift the chin to open the airway. 4. Check for breathing: Look, listen, and feel for normal breathing for no more than 10 seconds. 5. Provide rescue breaths: If there's no normal breathing, give 1 breath every 5 to 6 seconds (about 10-12 breaths per minute). Remember, the key is to provide oxygen to the patient's brain and other vital organs until they can breathe on their own or until professional medical help arrives. read more >>
