What is the best, most accurate description for "agonal respirations"?
An attempt to breathe through congested nasal passages causing loud sounds
Respirations that are fast and labored
An ineffective gasping, gulping type of attempt to breathe that does not look normal
Mouth breathing that is less than 12 breaths per minute

The best description is 3) An ineffective gasping, gulping type of attempt to breathe that does not look normal. This is because agonal breathing (or “gasping breathing”) is a brainstem reflex which occurs when the heart isn’t effectively circulating oxygen-rich blood anymore. This type of breathing is the body’s last attempt at getting more oxygen, though it usually results in death since it is inefficient at getting oxygen to the blood.
