Elderly people, due to common hypertension, cardiovascular and cerebrovascular diseases and other reasons, often faint. When you see an elderly person faint, it is usually necessary to immediately place the fainting elderly person in a lying position and not to move or shake their head significantly. Different home first aid measures should be taken for different conditions when the elderly faint. For the elderly with vomiting symptoms, the head should be tilted to one side so that oral secretions and vomit can flow out easily to avoid asphyxiation due to airway obstruction by vomit inhalation; for the elderly with hemoptysis symptoms, they should lie down on the side known to be sick, which can compress the affected lung and reduce the breathing movement on the affected side to reduce bleeding; for the elderly with asthma, respiratory distress or severe heart failure, it is advisable to For elderly with asthma, respiratory distress or severe heart failure, the head-high-foot-low or semi-recumbent position is preferred to reduce venous blood flow back to the lower extremities, reduce the burden on the heart and improve respiratory distress caused by cardiac insufficiency; for the elderly in shock (sudden drop in blood pressure, etc.), the lower extremities should be taken in a lying position 20-30 cm above the head and the head should be tilted to one side to keep the airway open; for those with respiratory distress, the semi-recumbent position is preferred. For the elderly who have wounds on the waist, back and hip and cannot lie flat or on the side, they can adopt the prone position, but pay attention to tilting the head to the side to avoid suffocation; for the elderly with suspected cerebral hemorrhage, they can adopt the head-high and foot-low position to minimize vibration, and the movement should be especially light when carrying. For the elderly with bleeding extremities, the injured extremity should be padded high and above the level of the heart to reduce bleeding.
