When taking a bath, because the space is relatively confined, it is easy to cause hypoxia and fainting. In addition, the stimulation of hot water in the bath causes blood vessels to dilate and blood flow speed up, resulting in dizziness and even fainting due to insufficient blood supply to the brain. Some patients who faint can wake up after a few seconds or minutes, at which time the patient should immediately squat or lie flat on the floor. Patients who have the ability to move should leave the bath immediately to avoid fainting again. There are some patients who fainted for a long time and cannot save themselves, but are found by family members or roommates, so they can be rescued by the following methods: 1. immediately move to a place with air circulation, lift the patient out of the bathroom, get out of the low-oxygen environment, take a flat position, you can use a book or clothing to put your legs up properly, so that the heart blood is concentrated in the head; 2. use a dry towel or clothing to wrap body, to avoid the cold wind blowing directly causing a drop in body temperature; 3, the patient is conscious can be properly fed some drinks, such as fruit juice, plain water, etc., to replenish body fluids and restore physical strength; 4, carefully check whether there is trauma, there are trauma, you can carry out simple disinfection and bandaging; 5, if the patient appears confused, impaired consciousness, it is recommended to immediately send to the hospital for medical treatment or call the emergency number, ask professionals to help deal with.
