Apgonal breathing is primarily caused by what?

Apgonal breathing is primarily associated with severe impairment of the brain's ability to regulate breathing, often linked to significant neurological compromise. This type of breathing is characterized by gasping, labored breaths that occur in terminal conditions. The term “preterminal” emphasizes that it is typically seen in the final stages of life, particularly when there is a failure in brainstem function, which is responsible for involuntary respiratory control.

In the context of respiratory care, recognizing apgonal breathing is crucial because it can indicate a rapid deterioration of the patient’s condition, often leading to loss of consciousness or death. While other conditions like severe lung obstruction or cardiac arrest can influence the respiratory system, apgonal breathing itself directly arises from central nervous system failures rather than from obstructive or acute airway issues. This understanding aids in assessing patients in critical situations and implementing timely interventions.
