signs of awakening from deep coma

the precursor to awakening from a deep coma is a gradual transition from a deep coma to a light coma. usually the patient gradually responds to external stimulation, such as violent sound and light stimulation, and also begins to gradually react to painful stimulation, and appears conscious. and unconscious movements and eye movements.
before the patient wakes up, the corneal reflex, swallowing reflex, cough reflex, pupillary direct light reflex, and indirect light reflex all begin to show signs of gradual existence. deep reflexes, such as tendon reflexes, also begin to diminish and become less present. the patient's vital signs such as breathing, pulse, blood pressure, and body temperature tend to stabilize.

the patient begins to respond to obvious stimuli, and these precursors prove that the patient is transitioning from deep coma to gradual awakening.
