The amount of He in the spirometer is known at the beginning of the test (concentration × volume = amount). The patient is then asked to breathe (normal breaths) in the mixture starting from FRC (functional residual capacity), which is the gas volume in the lung after a normal breath out. The spirometer measures helium concentration.
The helium dilution technique for measuring lung volumes uses a closed, rebreathing circuit. [6] This technique is based on the assumptions that a known volume and concentration of helium in air begin in the closed spirometer , that the patient has no helium in their lungs, and that an equilibration of helium can occur between the spirometer ...
Heliox is a breathing gas mixture of helium (He) and oxygen (O 2).It is used as a medical treatment for patients with difficulty breathing because this mixture generates less resistance than atmospheric air when passing through the airways of the lungs, and thus requires less effort by a patient to breathe in and out of the lungs.
The helium is included as a substitute for some of the nitrogen, to reduce the narcotic effect of the breathing gas at depth and to reduce the work of breathing. With a mixture of three gases it is possible to create mixes suitable for different depths or purposes by adjusting the proportions of each gas.
A Helium analyzer is an instrument used to identify the presence and concentration of helium in a mixture of gases. In Technical diving where breathing gas mixtures known as Trimix comprising oxygen , helium and nitrogen are used, it is necessary to know the fraction of helium in the mixture to reliably calculate decompression schedules for ...

With cabinless plethysmography, the patient is seated next to a desktop testing device and inserts the mouthpiece into their mouth. The patient takes a series of normal tidal breaths for approximately one minute. During this tidal breathing, a series of rapid interruptions occurs, with a shutter opening and closing, measuring pressure and ...
