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.
Yes
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.
Since gasps (agonal breathing) will not sustain life, for an adult go immediately to CPR.
Agonal gasps are typically shallow and irregular breaths that occur when a person is near death or experiencing a severe medical emergency. These gasps are not effective for oxygenation and often indicate a critical condition. They can be mistaken for normal breathing, but they are a sign of significant distress in the body.
open the airway and give two breath/check the victim pulse
CPR for an adult
Tip the head to open the airway. If still agonal breathing, give 2 breaths & start CPR.
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 breathing refers to a gasping, labored form of breathing that occurs in individuals who are near death or experiencing a severe medical crisis. It is often characterized by irregular, shallow breaths and may be accompanied by sounds such as snoring or gurgling. This type of breathing can occur in situations such as cardiac arrest or severe brain injury and is not indicative of effective respiration. It is crucial to seek immediate medical assistance if someone is observed exhibiting agonal breathing.
If the victim is breathing normally, but not responding you should
no breath sounds
Since agonal breathing will not support life, when agonal breathing occurs it is the same as no breathing; so immediately proceed with care.
