Pulmonary function testing - Wikipedia

WebTotal lung capacity (TLC) is commonly measured in the pulmonary function testing (PFT) laboratory either by gas dilution (usually with helium [He]), or whole-body plethysmography (Pleth). These two techniques yield equivalent results among those with normal lung mechanical function. WebTwo methods, helium (He) dilution and nitrogen (N 2 ) washout, involve having the patient breathe gases or gas concentrations not normally present in the lungs: He or 100% oxygen (O 2 ).
