Solunum Sistemi Anormal Bulgusu II: Palpasyon ve Oskültasyon

Tracheal deviation, a displacement of the trachea from its normal midline position, signals serious conditions requiring urgent attention. Tracheal shift toward the unaffected side typically indicates tension pneumothorax or large pleural effusion. This finding during physical assessment of the respiratory tract palpation helps clinicians identify life-threatening pathology and guide immediate intervention.

Tactile fremitus, vibrations felt on the chest wall during speech, changes distinctly with different conditions. Increased fremitus occurs in pneumonia or pulmonary edema, where fluid or consolidation enhances vibration transmission. Conversely, decreased fremitus appears in pleural effusion or pneumotharax, where air or fluid interrupts transmission of these vibrations.

Fine crackles are short, high-pitched sounds at the end of inspiration associated with pneumonia, idiopathic pulmonary fibrosis, or early pulmonary edema. Coarse crackles are longer, lower-pitched sounds indicating more severe fluid accumulation, as seen in heart failure or severe pulmonary edema. Each crackle type reflects different degrees of airway and parenchymal involvement.

Rhonchi are continuous, low-pitched sounds resembling snoring caused by obstructions in larger airways due to mucus, often indicating COPD or cystic fibrosis. Wheezes are high-pitched, musical sounds during expiration reflecting narrowed airways from bronchospasms, foreign bodies, or tumors. Both abnormal sounds indicate different levels and types of airway compromise.

Stridor is a high-pitched, wheezing sound notably during inspiration, caused by obstructions at the trachea or larynx level, seen in croup or foreign body aspiration. Unlike wheezes occurring during expiration or rhonchi from larger airway mucus, stridor specifically indicates upper airway obstruction requiring prompt evaluation and intervention.

Unequal chest movement during breathing often occurs in unilateral lung diseases such as atelectasis, pneumotharax, or pleural effusion. This asymmetrical expansion indicates that one lung is not functioning normally. Generalized decreased chest movement, conversely, suggests restrictive lung diseases or respiratory muscle weakness affecting both sides.

Voice sound changes including bronchophony, whispered pectoriloquy, and egophony reflect enhanced lung density that carries sound more efficiently. These findings are typically pronounced in pneumonia or pleural effusion, where consolidation or fluid increases sound transmission through lung tissue, helping clinicians identify areas of pathology.
