what are the clinical manifestations of deep coma?

the clinical manifestations of deep coma are that the patient has no response to any stimulus, the surrounding muscles are relaxed, the eyeball is fixed, the pupil is dilated, and the direct pupil light reflex, indirect light reflex, and corneal reflex are all lost. cough reflex, swallowing reflex, abdominal wall reflex, tendon reflex, brainstem reflex, etc. are also among the disappearing symptoms.

vital signs will also gradually change. the heart rate will gradually slow down, the blood pressure will gradually decrease, the pulse will gradually decrease, the breathing rate will increase from the initial rate to gradually slow down, and the body temperature will gradually decrease. these situations all involve the patient's deep coma involving the brain stem, resulting in changes in clinical signs.(warm reminder: medical science sharing. this content does not represent face-to-face consultation. if you feel unwell, please seek medical treatment as soon as possible.)
