Consciousness, inability to move the body, breathing difficulties, may be caused by sleep paralysis, cervical spinal cord injury, electrolyte disorders and other factors, we need to go to the hospital in time, after a clear diagnosis and symptomatic treatment. This situation is extremely critical, and it is recommended to be handled by a professional doctor.1. Sleep paralysis: It is a common sleep disorder, which often occurs during the stage of falling asleep and waking up, and the patient will suddenly wake up, but the body can not move, and may be accompanied by symptoms such as chest tightness and breathing difficulties, and most of them can be restored to normal within a few seconds or minutes. Usually, no treatment is needed. When repeated attacks occur and cause clinical pain, low-dose 5-hydroxytryptamine reuptake inhibitors can be taken under the guidance of the doctor to alleviate the clinical symptoms; 2. Cervical spinal cord injury: the cervical spinal cord is very sensitive and fragile, and usually, the cervical spinal cord is prone to paraplegia after the injury, and the patient’s whole body can not be moved except for the neck and above, and the respiratory muscles are weakened, causing dyspnea. The patient can no longer move his/her body from the neck upwards and may have difficulty breathing due to the weakening of the respiratory muscles, but he/she may remain conscious at all times. In this case, it is necessary to go to the hospital as soon as possible to carry out the necessary treatment, and it may be necessary to carry out surgical treatment in order to release the pressure on the spinal cord, which can alleviate the discomfort of the patient to a certain extent, but it is best for professional doctors to carry out on-site treatment and transportation; 3. Electrolyte disorders: this is a relatively rare case, which is the effect caused by electrolyte disorders, for example, the patient may have a significant low-potassium condition, and the patient with severe low potassium will have generalized weakness or even be unable to move, and the patient may be unable to move. There will be generalized weakness or even inability to move, due to tension or inability to adapt, the patient may have obvious respiratory difficulties, but the patient is conscious. In this case, blood potassium ions need to be checked, and the amount of potassium supplementation should be decided according to the severity of the decrease in blood potassium ions. The clinical symptoms will be relieved when the potassium is normalized or nearly normalized, and then the cause of the hypokalemia should be determined and further treatment should be carried out to address the cause.
