Lung and pleura percussion

Pulmonary and pleural percussion is based on the physical characteristics of the thoracic and lung tissues, and the different sounds produced during the sniper are used to determine whether the lungs have lesions and their nature. Methods of percussion include direct percussion and indirect percussion. Indirect percussion is a common method of percussion. At the time of percussion, the plate finger is placed flat in the intercostal space and parallel with the rib; when the interscapular region is diagnosed, the plate finger is parallel to the spine; often the fingertip of the right middle finger is used to vertically slam the plate finger, and the percussion action is mainly performed by the movement of the wrist joint. The sniper should be fast and short, and the sniper force should be moderate and even. After the sniper, the right middle finger is lifted up quickly, and each sniper is 2~3 times. Basic Information Specialist Category: Respiratory Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Poor rest before check, improper diet, excessive fatigue. Normal value The unvoiced sound is the percussion sound of the normal lung, showing a mid-low tone. Clinical significance Abnormal results: 1. Voiced and real: Common lesions include: (1) Diseases with reduced gas content such as inflammation and consolidation of lung tissue. Such as pneumonia, tuberculosis, pulmonary infarction, atelectasis and so on. (2) pleural cavity lesions, such as pleural effusion, pleural thickening. (3) chest wall disorders, such as chest wall edema or chest wall tumors. 2. Drum sound: See a large cavity or pneumothorax in the lungs. Such as tuberculosis, lung abscess, tumor or lung cyst formation, and congenital pulmonary bullae. 3. Over-voiceless: Common in emphysema, which is the weakening of lung elasticity and the increase of gas content. People who need to be examined: people with abnormalities in the lungs and pleura. Precautions Taboo before the examination: poor rest, improper diet, excessive fatigue. Requirements for inspection: Actively cooperate with the doctor's work. Inspection process 1. Let the patient take a seat or supine position, breathe evenly and relax the muscles. 2. During the percussion, the plate finger is placed flat in the intercostal space and parallel with the rib; when the interscapular region is referred to, the plate finger is parallel to the spine; often the fingertip of the right middle finger is used to vertically slam the plate finger, mainly to complete the percussion action with the movement of the wrist joint. . The sniper should be fast and short, and the sniper force should be moderate and even. After the sniper, the right middle finger is lifted up quickly, and each sniper is 2~3 times. 3. When examining the front chest, the chest is straight, starting from the supraclavicular fossa, and then palpating from the top of the first intercostal space from top to bottom. 4. When the side chest is percussed, the patient's upper arm is lifted to the head and the percussion begins from the armpit and down to the costal margin. 5. When the chest is diagnosed, the patient's head is slightly lower, the elbow is crossed, and the upper body is tilted forward. Starting from the tip of the lung, after the width of the isthmus of the lung is removed, the iliac crest is removed from the intercostal space. . Not suitable for the crowd Inappropriate crowd: None. Adverse reactions and risks Nothing.
