Early cardiac asthma

"Cardiac asthma," namely "paroxysmal night breathing difficulties." Due to hypertensive heart disease, coronary heart disease caused by the chronic heart failure, More common in the elderly. Patients with heart disease often sleeping 1-2 hours after suddenly feel chest tightness, dyspnea and wakened, often require rapid Zuoqi, and a frequent cough, big mouth breathing, vomit bubble-like sputum. After several minutes to light gradually, and will re-appear the risk of acute pulmonary edema symptoms, there are obvious Wheezing Music "heartbeat accelerated, lips cyanosis, 1,10-bubble-like powder cylinder sputum The incidence of cardiac asthma, sleep, mainly because of some blood from the lower half transfer to the lungs, thereby increasing the original left ventricular failure caused by chronic lung Yu blood; the supine position, FVC reduced to a ventilation obstacles, and cause hypoxia. Carbon dioxide retention, resulting in pulmonary hypertension, an increase of the reflection on the respiratory center stimulation. In addition, the intensity of human activities, with the changes in circadian rhythm shows that changes in sympathetic nerve activity during the day strong, vagus nerve activity at night dominant, rendering coronary artery contraction, myocardial blood supply reduction. This is the heart of the direct cause of asthma in the -. Joinet emergency handling this disease: first sitting of patients admitted with severe illness in the legs will be sitting down and use a soft cloth band ligation rotation of the three limbs in the limbs, and every five minutes for a physical扎, the aim is to reduce output Rhodobryum roseum, reduce heart burden, to gain time to do further Jisong hospital diagnosis and treatment.
