Gasping respiration, also known as agonal breathing, is an abnormal breathing pattern characterized by irregular, shallow, and labored breaths, often accompanied by strange vocalizations, and is a sign of a life-threatening emergency like cardiac arrest.
Here's a more detailed explanation:
What it is:
Agonal breathing is a brainstem reflex that occurs when the brain is not getting enough oxygen (hypoxia or anoxia).
How it looks:
It manifests as irregular, gasping, or labored breaths, often with a sound like snoring, snorting, or gasping.
Why it's important:
Agonal breathing is a critical sign of a life-threatening emergency, such as cardiac arrest, and indicates the failure of the patient's cardiac and respiratory functions.
What to do:
Healthcare professionals or first responders encountering a patient exhibiting agonal breathing should promptly initiate cardiopulmonary resuscitation (CPR) and call for emergency medical assistance.
Causes:
Possible causes include cerebral ischemia, hypoxia, or anoxia.
Important Note:
Gasping is not normal breathing and should not be mistaken for normal breathing.
Gasping in cardiac arrest:
Gasping often follows cardiac arrest and is considered an "auto-resuscitative" phenomenon.
Gasping and resuscitation:
Gasping can actually improve blood flow and oxygen delivery to the brain, and studies have shown that patients who gasp during cardiac arrest have a higher chance of survival.
Gasping at the end of life:
In some cases, agonal respiration can be a sign of the dying patient's last breaths before terminal apnea.
Ethical considerations:
There are ethical considerations regarding the use of neuromuscular blockade to suppress prolonged episodes of agonal respiration in well-sedated patients to allow a peaceful death.
