Body plethysmography vs nitrogen washout
WebNitrogen Washout This technique is based on washing out the N2 from the lungs, while the patient breathes 100% O2 using dilution properties of gases. The patient breathes 100% oxygen, and all the nitrogen in the lungs is washed out. The exhaled volume and the nitrogen concentration in that volume are measured. Webby two major techniques: plethysmography (utilizing adult and infant body-boxes), and gas dilution or wash-out techniques. The most commonly used are helium (He) dilution (a …
