Most respiratory disorders are characterized by coughing and sputum. Sputum can be grayish-white mucus sputum or yellowish-green pus sputum, and sometimes sputum coughed up with bright red blood is called hemoptysis. The medical term for bleeding from the trachea, bronchus or lung tissue below the larynx that is expelled from the body by coughing is hemoptysis. 1, stop bleeding; 2, prevent airway obstruction; 3, maintain the patient’s vital functions. General therapy 1, sedation, rest and symptomatic treatment. 2. For moderate hemoptysis, measure blood pressure, pulse and respiration at regular intervals. Encourage the patient to cough slightly and cough out the blood so that it will not be retained in the respiratory tract. In order to prevent the patient from straining to defecate and aggravate hemoptysis, the stool should be kept unobstructed. For patients with hemoptysis accompanied by shock, attention should be paid to heat preservation. For patients with high fever, an ice bag can be placed on the chest or head, which is favorable for cooling and stopping hemoptysis. Attention should be paid to the discovery of early signs of asphyxia, and be prepared to rescue asphyxia. In the case of hemoptysis and asphyxia, the patient should be drained immediately, and the blood should be poured out as much as possible, or the blood in the larynx or trachea should be sucked out with a suction device.
