non-invasive
A medical procedure neither invasive nor involving an invasive action, not tending to
spread, especially not tending to invade healthy tissue.
ohms
A unit of electrical
ampere
(1787-1854).]
pulse
The regular expansion of an artery caused by the ejection of blood into the arterial system
by the contractions of the heart.
pulse oximeter
A non-invasive, arterial, oxygen-saturation monitor that measures the ratio of two
principle forms of
PVCs
Premature ventricular contractions. A condition characterized by an irregular heartbeat
caused by an abnormal, or ectopic, ventricular pacemaker.
resistance
The opposition to electric current characteristic of a medium, substance, or circuit
element.
RS232
The RS232 interface provides an electrical description for connecting peripheral devices
to computers using either a 25-pin connector or a 9-pin connector.
Generally speaking, personal computers are data terminal equipment (DTE) devices and
peripherals such as printers, mice, modems, and the Index2 are data communication
equipment (DCE) devices. When connecting two like devices (a printer connected to
Index, for example), you must use a null modem cable. See also serial port.
R-Value
The non-pulsating components of tissue, specifically the tissue bed, the
the
component.
SaO 2
Abbreviation for saturated oxygen, SaO2 is the ratio of the concentration of
oxyhemoglobin (cHbO 2 ) to the concentration of the two principle types of blood
hemoglobin: saturated hemoglobin (HbO 2 ) plus reduced hemoglobin (Hb).
serial port
An
a printer, a mouse, or even the Simulator connects to a computer or other device. Serial
(COM) ports send and receive data one bit at a time over a single line, as opposed to
parallel communications where multiple wires in the cable send data in multiple bits. See
also RS232.
