Pulmonary impedance flow diagram

Pulmonary impedance blood flow map is an examination method that can not only diagnose pulmonary heart disease early, but also early detection of pulmonary hypertension and recessive pulmonary hypertension. It is intravenously delivered to the pulmonary artery to directly measure the pulmonary artery and right ventricular pressure. It can be used for early diagnosis of pulmonary heart disease, but it is a traumatic method that is difficult for patients to accept, especially in primary hospitals. Basic Information Specialist Category: Respiratory Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Pay attention to normal eating and eating habits. Normal value The lungs are normal and there are no symptoms of the disease. Clinical significance Not only can early diagnosis of pulmonary heart disease, but also early detection of pulmonary hypertension and recessive pulmonary hypertension. Pulmonary impedance blood flow map and its differential map examination can reflect the changes of pulmonary blood flow volume in the body, understand the hemodynamic changes of pulmonary circulation, pulmonary artery pressure and right heart function. Abnormal result Long-term cough, expectoration, and varying degrees of difficulty breathing, especially after activity or during the cold season. In the compensatory period of cardiopulmonary function, the patient may have no symptoms when he is quiet. Once he is slightly active, symptoms such as shortness of breath, shortness of breath, palpitations, pain in the precordial area, fatigue, and chest tightness may occur. People to be examined: patients with pulmonary heart disease, or suspected pulmonary hypertension and recessive pulmonary hypertension. Precautions Taboo before the test: pay attention to normal eating habits. Requirements for inspection: Actively cooperate with the doctor. Inspection process Intravenously feeding the floating catheter to the pulmonary artery and directly measuring the pulmonary artery and right ventricular pressure can be used for early diagnosis of pulmonary heart disease, but it is a traumatic method that is difficult for patients to accept, especially in primary hospitals. Noninvasive conversion of pulmonary artery pressure using a pulmonary impedance blood flow map is a simple and easy method. Pulmonary impedance blood flow map for diagnosis of pulmonary heart disease criteria: 1. The Q-B interval is significantly prolonged or greater than or equal to 0.14 seconds. 2. The Q-Y interval is significantly shortened or greater than or equal to 0.26 seconds. 3. The Q-B index is significantly increased by a value greater than or equal to 0.18, and the heart rate will be positive for the Q–B interval. The index is significantly reduced by 0.15 seconds or less. The HS is significantly reduced by 0.15 ohms or less. In the history of chronic bronchitis, emphysema, asthma and other diseases, there are three positive cases that can diagnose pulmonary heart disease.
