Pulmonary Function Testing:
These tests measure how well the lungs take in and release air and how well they move oxygen into the blood.
Bronchoscope is a procedure during which an examiner uses a viewing tube to evaluate a patient's lung and airways including the voice box and vocal cord, trachea, and many branches of bronchi. Bronchoscope is usually performed by a pulmonologist or a thoracic surgeon. Although a bronchoscope does not allow for direct viewing and inspection of the lung tissue itself, samples of the lung tissue can be biopsied through the bronchoscope for examination in the laboratory.
Arterial Blood Gases:
A sample of blood from an artery is usually taken from the inside of the wrist (radial artery), but it also can be collected from an artery in the groin (femoral artery) or on the inside of the arm above the elbow crease (brachial artery). A patient will be seated with arm extended and with the wrist resting on a small pillow. The health professional drawing the blood may rotate the patient’s hand back and forth and feel for a pulse in the wrist.
