Pulmonary heart disease, referred to as pulmonary heart disease, is a heart disease caused by chronic lesions of the bronchi, lungs, thorax or pulmonary arteries that increase circulatory resistance, pulmonary hypertension, which leads to hypertrophy and enlargement of the right ventricle and even right heart failure, with many comorbidities, high mortality rate, and variable and changeable conditions. Therefore, it is very important to observe the condition. Especially at night, due to various factors, it is easy to ignore the importance of nursing observation. Zhao Yong, Cardiac Arrhythmia Treatment Center, Guangdong Provincial Hospital of Traditional Chinese Medicine I. Analysis of the nursing situation at night 1. The patient’s own pathophysiological characteristics The vagus nerve is excited at night, the cerebral cortex’s regulation of the respiratory center is relatively reduced, prompting the occurrence or aggravation of respiratory failure. 2. Factors on the part of nursing staff Nurses are mostly female, physically weak, and once a month The physiological period, disturbance of biological clock at night, extreme physical sleepiness, one person on duty at night, unsupervised, without a strong sense of responsibility, good moral cultivation and self-control, easy to relax the observation of the patient. 3. Reasons on the part of the nursing staff The nursing staff accompanying the patient at night often cannot adapt to the disturbance of biological clock and fall asleep sleepily, making it difficult to provide information about the changes. II. Observation and care (1) Sputum excretion and humidification to keep the respiratory tract unobstructed. Sputum is prone to concentration and aggregation at night, coupled with the weakened coughing and coughing reflex at the bottom of the excretory function, which makes it difficult to discharge respiratory secretions and increases airway resistance and aggravates the condition. (2) Oxygen therapy nursing observation: continuous low-flow oxygen, the patient is in sleep state at night, the oxygen inhalation tube is easy to fall off and obstruction, frequent inspection to keep the smooth, do a good job of family missionary work, can not adjust the oxygen flow, to ensure the normal implementation of oxygen therapy. Oxygen therapy should be closely observed in the process of vital signs, cyanosis and other conditions, so as to better adjust the oxygen flow or concentration. (3) Closely observe the changes of mental and psychiatric status, and find that the patients are drowsy, irritable, in a trance, and excited about sleeping at night, which are the early clinical manifestations of pulmonary encephalopathy. (4) Resuscitate critically ill patients well and prepare suction tubes, tracheal intubation, and ventilators for timely resuscitation of patients. (5) Be cautious with sedative sleeping pills, be alert to callousness when the patient is restless, and avoid taking sleeping pills and sedatives at will to avoid triggering or aggravating the disease. by huanglishan Guangdong Provincial Hospital of Traditional Chinese Medicine Cardiac Arrhythmia Treatment Center wishes you good health!
