plethysmograph

 [plĕ-thiz´mo-graf]
any device for measuring and recording variations in the volume of an organ, part, or limb.
body plethysmograph a device used in pulmonary function tests to measure parameters such as functional residual capacity (FRC) and lung-thorax compliance (CLT). It consists of a large box in which the subject can be sealed so that volume of the thorax can be determined from pressure changes in the box.

ple·thys·mo·graph

(ple-thiz'mō-graf),
A device for measuring and recording changes in volume of a part, organ, or whole body.
[G. plēthysmos, increase, + graphō, to write]

plethysmograph

/ple·thys·mo·graph/ (plĕ-thiz´mo-grah) an instrument for recording variations in volume of an organ, part, or limb.

plethysmograph

(plĕ-thĭz′mə-grăf′, plə-)
n.
An instrument that measures variations in the size of an organ or body part on the basis of the amount of blood passing through or present in the part.

ple·thys′mo·graph′ic adj.
pleth′ys·mog′ra·phy (plĕth′ĭz-mŏg′rə-fē) n.

plethysmograph

[pləthiz′məgraf′]
an instrument for measuring and recording changes in the size and volume of extremities and organs by measuring changes in their blood volume. plethysmographic, adj.

body plethysmograph
a device used in pulmonary function tests to measure parameters such as functional residual capacity (FRC) and lung-thorax compliance (CLT). It consists of a large box in which the subject can be sealed so that volume of the thorax can be determined from pressure changes in the box while the lung volume and gas pressure in the lungs are measured by spirometry.

In 2005, Masimo introduced rainbow[R] SET Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously required invasive procedures, including total hemoglobin (SpHb[R]), oxygen content (SpOC), carboxyhemoglobin (SpCO[R]), methemoglobin (SpMet[R]), and Pleth Variability Index (PVI[R]), in addition to SpO2, pulse rate, and perfusion index (PI).
Another MightySat function that trickles down from clinicalgrade monitors is the pleth variability index, or PVI.
Masimo (NASDAQ: MASI) announced today that it has added a new parameter, respiration rate from the pleth (RRpTM), to its MightySat fingertip pulse oximeter.
The MightySat noninvasively measures arterial oxygen saturation and pulse rate, in addition to perfusion index and optional pleth variability index.
HP Wave Viewer allows a clinician to view ECG and pleth waveforms, pulse rate and SpO2 value at a patient's side to make an assessment without always having to refer to the central monitoring station or to attach a patient monitor.
The device can also measure and display Pleth Variability Index, a measure of the dynamic changes in the perfusion index that occur during one or more complete respiratory cycle/s.
The MightySat noninvasively measures arterial oxygen saturation (SpO2) and pulse rate (PR), in addition to perfusion index (PI) and optional pleth variability index (PVI).
Masimo announced today that an 18-study meta-analysis of 665 subjects reported that Masimo's Pleth Variability Index (PVI), available with Masimo's SET and rainbow SET monitoring platforms, may help clinicians assess fluid responsiveness in mechanically ventilated patients in normal sinus rhythm in the operating room and intensive care unit.
5 pounds, iSpO2 also displays the pleth waveform and Signal IQTM so users can visually assess their pulse rate and measurement quality to help optimize workouts and fitness levels.
In 2005, Masimo introduced rainbow SETA Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously required invasive procedures, including total hemoglobin (SpHbA), oxygen content (SpOCTM), carboxyhemoglobin (SpCOA), methemoglobin (SpMetA), and Pleth Variability Index (PVIA), in addition to SpO2, pulse rate, and perfusion index (PI).
The Health Centre also has the option to upgrade at any time to Masimo rainbowA Pulse CO-Oximetry , which allows clinicians to noninvasively monitor multiple blood constituents that previously required invasive or complicated procedures, including total hemoglobin (SpHbA), oxygen content (SpOC ), carboxyhemoglobin (SpCOA), methemoglobin (SpMetA), Pleth Variability Index (PVIA), and acoustic respiration rate (RRa ).
