breath-hold test

The breath test is a lumps located on the anterior wall of the abdomen and behind the abdominal muscles, which are examined according to the following principles, and it is sometimes difficult to distinguish their position by routine examination. When the abdominal muscles are forced to contract and the abdominal wall tension is increased, the mass located on the anterior wall of the abdomen pushes it outward due to contraction of the abdominal muscles, which becomes more clear, and the mass located behind the abdominal wall becomes blocked due to the tension of the abdominal muscles. Not easy to reach. Basic Information Specialist Category: Respiratory Examination Category: Physical Examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: A negative indication of a deeper location of the mass, located in the extraperitoneal fat layer behind the abdominal muscles, the peritoneal wall layer, the intraperitoneal or retroperitoneal space. Positive: A positive indication indicates that the mass is located above the anterior wall of the abdomen and is shallow. Tips: During the test, the subject can hold the nose with his hand to avoid air leakage. Normal value There is no lump in the abdomen. Clinical significance Identifying the number of layers of the abdominal mass cannot diagnose the cause. 1. Positive indicates that the mass is located above the anterior wall of the abdomen and is shallow. 2. Negative suggestion that the location of the mass is deep, located in the extraperitoneal fat layer behind the abdominal muscles, the peritoneal wall layer, the intraperitoneal or retroperitoneal space. Abnormal results: A lumps of different depths. The abdomen lumps of the crowd that need to be examined are unclear. Precautions Requirements for inspection: — When testing, the subject can hold the nose with his hand to avoid air leakage. Second, the length of the breath hold time can be affected by the will, the sensitivity is poor, the error can reach 15s. Third, it is recommended to use the diaphragmatic muscle contraction to objectively assess the length of the breath holding time. Inspection process When inspecting: -, during the test, the subject can hold the nose with his hand to avoid air leakage. Second, the length of the breath can be affected by the will, the sensitivity is poor, the error can reach 15s. Third, it is recommended to use the diaphragmatic contraction to objectively assess the length of the breath. Not suitable for the crowd Other people: mentally abnormal.
