phrenic phenomenon

Diaphragmatic phenomenon (diaphragmatic phenomenon) is also known as the "Li Teng phenomenon", also known as "Li Teng Zheng", "膈波影", "Li-Ge phenomenon". Taboo before the examination: poor rest, improper diet, excessive fatigue. The patient is in a supine chest breathing, with the foot on the light source, and the examiner sitting on one side and facing away from the light source. When the patient inhales, the ribs move down and the intercostal space subsides. It can be seen that a horizontal shadow shifts from the seventh intercostal space to the 9th or 10th intercostal space; when exhaled, it returns to the original position. The shadow moves about 6 cm when the normal person breathes evenly and 9 cm when the breathing is deep. Basic Information Specialist classification: Digestive examination classification: other examinations Applicable gender: whether men and women apply fasting: not fasting Tips: Actively cooperate with the doctor's work. Normal value The shadow moves about 6 cm when the normal person breathes, and reaches 9 cm when breathing deeply, and the breathing is uniform. Clinical significance Abnormal result Pleural effusion, pleural thickening adhesions, pneumonia, atelectasis, severe pulmonary tuberculosis, pulmonary fibrosis, one side tendon spasm, one side of axillary abscess, pneumoperitoneum, massive ascites, pregnancy, large abdominal tumor, spontaneous tension pneumothorax, etc. . People who need to be examined: people with the above symptoms. Precautions Taboo before the examination: poor rest, improper diet, excessive fatigue. Requirements for inspection: Actively cooperate with the doctor's work. Inspection process The patient is in a supine chest breathing, with the foot on the light source, and the examiner sitting on one side and facing away from the light source. When the patient inhales, the ribs move down and the intercostal space subsides. It can be seen that a horizontal shadow shifts from the seventh intercostal space to the 9th or 10th intercostal space; when exhaled, it returns to the original position. The paralysis phenomenon disappears or the range of movement is reduced, indicating that the diaphragmatic muscles are weakened. One side of the sputum wave movement range is reduced, considering pleural effusion, pleural thickening adhesions, pneumonia, atelectasis, severe tuberculosis, pulmonary fibrosis, one side tendon spasm, one side subphrenic abscess, spontaneous tension pneumothorax. The range of sputum wave shadows on both sides is reduced, considering pneumoperitoneum, massive ascites, pregnancy, and huge tumors in the abdominal cavity. Not suitable for the crowd Inappropriate crowd: no Adverse reactions and risks Nothing.
