Body Plethysmography: Purpose, Procedure & Results - Cleveland Clinic
2022年12月18日 · Body plethysmography (pronounced “pleh-thiz-mah-graf-ee”) is a noninvasive type of lung function testing known as a pulmonary function test. It can help determine how much air is in your lungs after you take a deep breath in (inhale). It also helps determine how much air remains in your lungs after you take a deep breath out (exhale).
Whole-Body Plethysmography - CHEST
The “gold standard” for the measurement of lung volume and airway resistance (Raw) in all subjects is the whole-body plethysmograph, and has been for close to 50 years. 1,2 This method is based on Boyles law, which states that in an enclosed gaseous system under isothermal conditions (ie, with negligible temperature changes) the ...

2023年8月8日 · Body plethysmography is testing that's done to determine how much air your lungs can hold. It goes by other names, too, such as pulmonary plethysmography, static lung volume determination, or...
Body plethysmography – Its principles and clinical use
2011年7月1日 · Body plethysmography allows to assess functional residual capacity (FRC pleth) and specific airway resistance (sRaw) as primary measures. In combination with deep expirations and inspirations, total lung capacity (TLC) and residual volume (RV) can be determined.

体积描记(plethysmography，体描)一词来源于希腊语"plethysmos"，原意为"扩大，扩展"。 早在19世纪末就有学者提出，通过测量呼吸过程中胸腔容积"扩大"引起的人体体积的变化来测定功能残气量(FRC)，但直到1956年，DuBois等才发展出第一套基于波义耳定律(Boyle's law)的实用 ...
Body Plethysmography - Hopkins Medicine
Two of the most common methods of obtaining information about these volumes are gasdilution tests and body plethysmography. In body plethysmography, the patient sits inside an airtight box, inhales or exhales to aparticular volume (usually FRC), and then a …
Body Plethysmography - an overview | ScienceDirect Topics
Body plethysmography is a non-invasive procedure that provides static lung volume measurements related to air trapping and hyperinflation such as residual volume (RV), total lung capacity (TLC) and the RV/TLC ratio. You might find these chapters and articles relevant to …
Body Plethysmography (Lung Function Test): How It's Done
2020年11月15日 · Body plethysmography is a simple, painless test that takes lung volume measurements. The test involves sitting in an airtight booth and blowing into a mouthpiece while a computer records measurements. Body plethysmography helps diagnose respiratory diseases.
Whole-body Plethysmography - Respiratory Therapy
2007年2月7日 · During whole-body plethysmography, the patient sits or stands inside an airtight chamber and inhales or exhales to a particular volume (usually FRC); a shutter then drops across the breathing tube. The patient makes respiratory efforts against the closed shutter, causing chest volume to expand and decompressing the air in the lungs.
