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-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]

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.

LONDON, June 10, 2012 /PRNewswire/ -- Masimo(NASDAQ: MASI) announced today the National Health Service Technology Adoption Centre in the United Kingdom is advising hospitals to use Intraoperative Fluid Management Technologies as a way to improve patient outcomes, and included Masimo's noninvasive and continuous Pleth Variability Index (PVI) among technologies available for helping clinicians manage fluid during surgeries.
In 2005, Masimo introduced rainbow SET Pulse CO-Oximetry (TM) technology, allowing noninvasive and continuous monitoring of blood constituents that previously required invasive procedures, including total hemoglobin (SpHb), oxygen content (SpOC (TM)), carboxyhemoglobin (SpCO), methemoglobin (SpMet), and Pleth Variability Index (PVI), in addition to SpO2, pulse rate, and perfusion index (PI).
Given that the SpHb ReSposable Sensor also provides Masimo SET[R] SpO2, pulse rate, perfusion index (PI), methemoglobin (SpMet), and pleth variability index (PVI) measurements, the new sensor pricing makes it possible for SpHb to become a new standard of care for all patients throughout the continuum of care.
The Patient SafetyNet™ system features a noninvasive patient sensor [finger or acoustic respiration neck sensor] and bedside patient monitor [Masimo Rad-87 or Radical-7 Pulse CO-Oximeter™] that continuously captures vital physiological measurements-including: total hemoglobin (SpHb), oxygen content (SpOC™), carboxyhemoglobin (SpCO), methemoglobin (SpMet), Pleth Variability Index (PVI), acoustic respiration rate (RRa™), oxyhemoglobin (SpO2), perfusion index (PI), and pulse rate (PR)-and wirelessly transmits them to the central monitoring station, which displays the real-time clinical status of all connected patients and instantly routes alarms to the pager or smartphone of assigned clinicians.

which helps clinicians to more quickly detect elevated levels of carbon monoxide in the blood - which can facilitate earlier diagnosis and treatment for patients poisoned by carbon monoxide; and Pleth Variability Index(PVI[sup.
Pulse CO-Oximetry (TM), which allows clinicians to noninvasively monitor multiple blood constituents that previously required invasive or complicated procedures, including total hemoglobin (SpHb), oxygen content (SpOC (TM)), carboxyhemoglobin (SpCO), methemoglobin (SpMet), Pleth Variability Index (PVI), and acoustic respiration rate (RRa (TM)).
Parameters in use include total hemoglobin (SpHb), oxygen content (SpOC (TM)), carboxyhemoglobin (SpCO), methemoglobin (SpMet), and Pleth Variability Index (PVI), in addition to the Measure-Through Motion and Low Perfusion performance of Masimo SET oxyhemoglobin (SpO[sub.
