voice tremor

Speech tremor is an important method of examination. The patient makes a sound, the vibration generated by the sound waves, along the trachea, bronchi and alveoli, and the vibration transmitted to the chest wall causes the resonance, the doctor can touch the hand, called voice tremor. The doctor's palm or ulnar side is lightly attached to the symmetrical part of the chest wall of the patient, but it can not be pressed against the chest wall to avoid weakening the sensitivity of the palm. Let the patient say that one or the other can feel a feeling of tremor, and the two hands alternately check whether the sides are the same, and pay attention to whether the unilateral, bilateral or local enhancement is weakened or disappeared. Basic Information Specialist Category: Respiratory Examination Category: Physical Examination Applicable gender: whether men and women apply fasting: not fasting Tips: Taboo before check: poor rest, improper diet, excessive fatigue. Normal value Under normal circumstances, men are generally stronger than women, adults are stronger than children, and leaners are stronger than those who are fat. The intensity of tremor is different in different parts of the same thorax. The upper right upper part of the chest is slightly stronger than the upper left part, because the right lung tip is closer to the trachea; the upper part of the front chest is slightly stronger than the lower part, because the former is closer to the glottis, the lower part of the lower chest is stronger than the upper part, because the upper part of the iliac and the muscle are thicker. The spur of the interscapular region is strong, because the area is close to the trachea, but these differences are small and often have no diagnostic significance, so the symptoms should be judged by the doctor's experience. Clinical significance Abnormal results: 1. Any pathological condition that enhances the transmission of sound waves to the chest wall may result in increased stimuli. It is mainly seen in the consolidation of lung tissue such as large leaf pneumonia due to inflammatory infiltration of lung tissue, and the alveolar gas content is significantly reduced. It becomes uniform, the sound is well transmitted, and the tremor is enhanced. 2. Anyone who hinders the transmission of sound waves to the chest wall can cause the tremor to weaken or disappear. Mainly seen in bronchial obstruction, such as obstructive atelectasis. People who need to be examined have the above symptoms. Precautions Taboo before the examination: poor rest, improper diet, excessive fatigue. Requirements for inspection: Actively cooperate with the doctor's work. The examinee repeats the "yi" long sound with the general sound intensity, and the vibration generated by the throat sound is transmitted to the chest wall through the trachea, bronchi, and alveoli, and is heard by the stethoscope. Inspection process The doctor's palm or ulnar side is lightly attached to the symmetrical part of the chest wall of the patient, but it can not be pressed against the chest wall to avoid weakening the sensitivity of the palm. Let the patient say that one or the other can feel a feeling of tremor, and the two hands alternately check whether the sides are the same, and pay attention to whether the unilateral, bilateral or local enhancement is weakened or disappeared. Not suitable for the crowd Inappropriate crowd: None.
