Definition of plethysmograph in English:

plethysmograph

noun plɪˈθɪzməɡrɑːfpləˈTHizməˌɡraf

Medicine

An instrument for recording and measuring variation in the volume of a part of the body, especially as caused by changes in blood pressure.
〔医〕体积描记器
Example sentencesExamples
- Lennox and coworkers found that drift of an inductive plethysmography signal was only 22% of the drift arising from changes in temperature within a body plethysmograph.
- Thus, the flows estimated in a body plethysmograph may not be fully available to the flow-limited subject.
- Lung volumes were measured in a whole-body plethysmograph, and data were expressed as a percent of the predicted values published by Goldman and Becklake.
- Functional respiratory variables in the animal models were measured with a double-chamber plethysmograph as described.
- Hulskamp and coworkers measured lung volume with a new plethysmograph in 32 healthy infants.

Derivatives

plethysmographic

adjective

Medicine

Before and after training, spirometry, plethysmographic lung volumes, and carbon monoxide diffusing capacity were assessed.
Example sentencesExamples
- Baseline specific airways conductance and airway responsiveness to histamine were measured using a non invasive body plethysmographic technique.
- The pulse oximeter also utilizes a plethysmographic waveform to differentiate pulsatile arterial hemoglobin saturation from venous blood.
- In contrast to findings in healthy adults and older children, in whom results are very similar, plethysmographic lung volumes in infants have been consistently higher than those obtained by gas dilution.
- These animal plethysmographic data are consistent with results from a large multicenter clinical study that demonstrated a high incidence of airway obstruction in sickle cell patients.

Origin

Late 19th century: from Greek plēthusmos 'enlargement' (based on plēthus 'fullness') + -graph.
