When the atelectasis involves a more significant portion of the lungs, the patient's respiratory rate will increase proportionally. Bronchial-type breath sounds may be present as the lung becomes more consolidated with atelectasis. Diminished breath sounds are common when excessive secre-tions block the airways and prevent transmission of breath sounds. The chest film is often used to confirm the presence of atelectasis.
