A pulmonary examination is a clinical assessment of the lungs and respiratory system. It typically involves observing the patient's breathing patterns, checking for any signs of distress, and listening to lung sounds using a stethoscope. The examiner may also assess the chest's shape and movement during inhalation and exhalation. During the examination, the healthcare provider may perform tests such as percussion and palpation to evaluate lung function and detect abnormalities. These assessments help identify conditions like asthma, pneumonia, or chronic obstructive pulmonary disease (COPD) and guide further diagnostic testing or treatment.
