Open the airway and check for breathing (signs of life; look, listen & feel); if not breathing give two breaths then start CPR.
Assuming the person is an adult, you would immediately begin CPR.
Tip the head to open the airway. Check for signs of life (look, listen, feel for breathing & movement). Since agonal gasps fails the breathing criteria, you would immediately begin CPR for an adult.
CPR for an adult
Tip the head to open the airway. If still agonal breathing, give 2 breaths & start CPR.
Yes
open the airway and give two breath/check the victim pulse
Since gasps (agonal breathing) will not sustain life, for an adult go immediately to CPR.
Agonal gasps are not productive and are not considered breathing. If patient has a pulse then give breaths at a rate of once every 5 seconds using a BVM attached to 100% o2 at 15lpm. CPR would be warranted if they are pulseless.
If the victim is breathing normally, but not responding you should
The correct spelling is agonal, and it is a term used to describe the respiratory rate and depth of a patient that is near death. It is characterized by slowing rate that becomes labored as the patient gasps. aka gulpy breathing. Agonal can also be used to describe a similar cardiac rhythm.
Agonal sounds is an official medical term for what would unscientifically be called the "death rattle". While the sound is entirely different in both timing and form with each person and situation, there is a distinct commonality acknowledged by those who are exposed to it regularly. There are both academic and professional conversations on what actions if any should be attempted once the sound has been heard.
