why can't i breathe on my own in a deep coma?

deep coma is the most severe degree of consciousness disorder. all deep and shallow reflexes in the patient's body disappear and cannot be elicited. muscle tone decreases, muscles relax, and pathological signs disappear. patients often have fixed mydriasis, loss of light reflexes, and may also experience decerebrate or decortical tonic attacks.

the patient's spontaneous breathing will be affected, and the breathing rhythm will be irregular. in severe cases, the spontaneous breathing will disappear. at the same time, the blood pressure will fluctuate, the pulse will weaken, the body temperature will drop, and the patient will be in a dying or dying state. the disappearance of spontaneous breathing is mainly related to the damage or suppression of the respiratory center. without central impulses to control breathing movements, the patient will not have respiratory impulses and needs a ventilator to assist breathing and barely maintain the patient's vital signs.
