There are two kinds of symptoms: 1 In patients with pulmonary edema, the examiner first auscultates the patient's lungs and finds that the lungs are covered with wet sounds, and then the same part is percussed. If it is found that it is not a normal unvoiced sound (an abnormal reaction occurs), it is called this, also called the summer lung sign. 2 Arteriosclerotic hypertension, when the position changes to the sitting position, the phenomenon of pulse rate reduction may occur. This is also known as the summer sign. Basic Information Specialist classification: Respiratory examination classification: pulmonary function test Applicable gender: whether men and women apply fasting: not fasting Tips: Taboo before check: poor rest, improper diet, excessive fatigue. Normal value The pulse is normal, the breathing is normal, and the chest sounds normal. Clinical significance Abnormal results pulmonary edema, lung field full of wet sound; arteriosclerotic hypertension, pulse rate reduction. People in the population who need to be examined have lung disease and cardiovascular disease. Precautions Taboo before the examination: poor rest, improper diet, excessive fatigue. Requirements for inspection: 1. The auscultation environment should be quiet and avoid interference; warmth should be avoided to avoid the additional sound of the patient due to muscle bundle vibration; to avoid the wind, it is beneficial to obtain better auscultation effect. 2.
