急性左心衰的临床表现及治疗措施 Clinical manifestations and treatment of acute left heart failure (a) symptoms Difficulty breathing is a subjective feeling of the sufferer, feeling breathless, breathing hard, shortness of breath and suffocating. Mild left heart failure, the patient can not have obvious discomfort in the quiet condition, the difficulty of breathing during physical activity, call the lab-breathing difficulty. In the case of the disease, even in a flat condition, the patient is short and breathless, relieved by sitting position and breathing. The main reason is that the blood flow to the lower extremities of the lower extremity of the lower extremity is increased, which further aggravates pulmonary congestion and pulmonary edema. And when you take the seat, the blood is transferred to the abdominal cavity and lower extremities, and the blood is silted down by gravity. The difficulty of breathing is alleviated by a decrease in the diaphragmatic muscle, increased chest capacity, and increased lung capacity. Patients with left heart failure, especially after sitting and breathing, often have difficulty breathing at night. When the patient is asleep, the patient is suddenly suffocated and the chest is stuffy, coughing and wheezing, sometimes accompanied by a bronchial spasm and asthma, known as cardiogenic asthma. Light is reduced after 10 minutes, but can continue to fall asleep. The heavy person can have pink foamy sputum and even develop to acute pulmonary edema. The mechanism may include: the blood flow to the lower part of the lower half of the lower body of the patient, and the swelling of the lungs and edema; The phrenic muscle rises, the lung capacity decreases; During sleep, the vagal tone increases, the bronchial aperture becomes smaller, the ventilation resistance increases, and the ventilation volume decreases. The sensitivity of the nerve reflex during sleep decreases, and when the pulmonary blood is filled with blood, it can stimulate the respiratory center
