Magnetic Resonance Therapy.
Non-Volatile Random-Access Memory.
Delivers oxygen directly into the common gas outlet without passing
through a flowmeter or vaporizer.
Post-anesthesia care Unit sometimes referred to as Post-Anesthesia
Recovery (PAR).
Patient Data Management System.
Peripheral Interface Controller.
An instrument for measuring changes in volume within an organ or whole
body (usually resulting from fluctuations in the amount of blood or air it
contains).
An oxygen delivery device that can be used as an alternative approach to
deliver positive pressure.
Transient increases in transpulmonary pressure designed to open
collapsed parts of the lung. Primarily used in Acute Respiratory Distress
Syndrome (ARDS).
The opposition to flow caused by the forces of friction. It is defined as the
ratio of driving pressure to the rate of air flow. Resistance to flow in the
airways depends on whether the flow is laminar or turbulent, on the
dimensions of the airway, and on the viscosity and density of the gas.
Rapid Shallow Breathing Index. The ratio of respiratory frequency to tidal
volume (f/VT).
Serial Peripheral Interface. A synchronous serial communication interface
specification used for short distance communication, primarily in embedded
systems.
Peripheral capillary oxygen saturation.
A surface-active lipoprotein complex (phospholipoprotein) formed by type II
alveolar cells. The proteins and lipids that make up the surfactant have
both hydrophilic and hydrophobic regions.
Used for testing Ventilator equipment.
A general direction in which something is developing or changing.
Universal Serial Bus, communication cables and connections.
Tidal Volume is the lung volume representing the normal volume of air
displaced between normal inhalation and exhalation when extra effort is not
applied.
