Final answer:
The priority action is to deliver rescue breaths when a patient has a pulse but is not breathing.
Step-by-step explanation:
When a patient has a pulse but is not breathing, the priority action is to deliver rescue breaths. This can be done by giving mouth-to-mouth resuscitation or by using a bag-valve-mask device.
To deliver mouth-to-mouth resuscitation, you should:
- Ensure the patient's airway is open by tilting the head back and lifting the chin.
- Pinch the patient's nose closed with your fingers.
- Take a normal breath and place your mouth firmly over the patient's mouth, forming a seal.
- Blow into the patient's mouth for about one second, allowing the chest to rise.
- Remove your mouth and allow the chest to fall. Repeat this step to deliver a total of two rescue breaths.
Remember to check for signs of breathing and circulation after delivering rescue breaths and continue with appropriate first aid procedures as needed.
