2011年7月1日 · The basic physical principle exploited by body plethysmography is the law of Boyle-Mariotte. For the present purpose this law can be concisely expressed as the statement …

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 …

Body plethysmography is a well-established technique of lung function determination. Its frequency of clinical use appears to differ between countries, with the most intensive …

2023年8月28日 · Boyle’s Law. Boyle’s law can be used to describe the effects of altitude on gases in closed cavities within the body, and to calculate the total intra-thoracic gas volume by body …

Boyle-Marriot’s Law • The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged …

Plethysmography uses Boyle's law in order to measure the intrathoracic gas volume or functional residual capacity, and once this is determined, the residual volume and total lung capacity is …

Determining lung volumes via plethysmography is achieved using Boyle's law regarding pressure–volume constants. A full body plethysmograph is a large (∼600–1000 L) airtight …

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 …

2015年8月1日 · Plethysmography uses Boyle's law in order to measure the intrathoracic gas volume or functional residual capacity, and once this is determined, the residual volume and …

2004年10月15日 · The body plethysmograph measures changes in volume of the whole body and is essentially a rigid box in which the patient sits while the small changes of pressure in the …
