Respiratory procedures are medical techniques used to diagnose and treat conditions affecting the lungs and airways. Common procedures include bronchoscopy, where a thin tube is inserted into the airways to view the lungs, and spirometry, which measures how much air a person can inhale and exhale. These tests help identify issues like asthma or chronic obstructive pulmonary disease (COPD). Other respiratory procedures may involve pulmonary function tests to assess lung capacity or chest X-rays to visualize lung structure. Treatments can include nebulization, where medication is delivered directly to the lungs, and mechanical ventilation for patients who need assistance breathing.
