Final answer:
During CPR, if a patient is not breathing but has a pulse, rescue breaths should be given at a rate of 1 breath every 3-4 seconds.
Step-by-step explanation:
The correct answer is A. 3-4 seconds.
During CPR, if a patient is not breathing but has a pulse, rescue breaths should be given at a rate of 1 breath every 3-4 seconds. This allows for enough time to deliver oxygen to the patient while also allowing for effective chest compressions.
It is important to continue performing high-quality chest compressions as the primary focus of CPR, as this helps maintain blood circulation to vital organs until the patient regains spontaneous contraction or is declared dead by a healthcare professional.
This timing is based on the average adult respiratory rate, which is roughly 12 to 16 breaths per minute. CPR's goal is to artificially maintain circulation and breathing in a person who is not breathing and does not have a heartbeat. It's critical to apply the correct technique and frequency for the best chance of survival until professional help can take over.
