pressure cycle See blood pressure cycle.
pressure envelope Graphic representation of cuff pressure as a function of time during a
blood pressure cycle
pressure envelope gain Increase or decrease in pressure envelope amplitude
pressure envelope shift Change of blood pressure envelope position along the pressure axis
pressure pulse Pulse, or temporary increase in blood pressure caused by the
intermittent rush of blood in the arteries due to the heart's pumping
action
pressure transducer Electronic device that converts pressure to a proportional voltage
signal
print test Test that the Analyzer performs to check printer operation
puck Small, moveable disk that creates positive and negative pressures
inside a chamber when moved by the Analyzer pressure engine
The action of the puck moving up and down within the puck chamber
produces the Analyzer oscillometric blood pressure simulations. The
puck inside the auscultatory mandrel simulates auscultatory blood
pressure.
pulse amplitude Height of the peripheral pulse
pulse envelope Imaginary line that connects the peak of each pressure pulse to form
an outline
NIBP monitors use pulse envelope shape to determine diastolic and
systolic blood pressures.
RAM Random Access Memory
remote mode Analyzer operating mode mediated with a controller (a medTester
with Checklist or a PC with an RS232 port)
returned data Information (values) sent to a controller from the Analyzer as a result
of a remote command
These values can be test results, information stored in the Analyzer
memory, or, if the remote command does not generate data, an
asterisk.
ROM Read Only Memory
The software program that operates the Analyzer is located in ROM
ROM checksum The mathematical sum of the software program code (in bytes)
stored in ROM
The code in ROM should never change once programmed at the
factory, and a ROM checksum value indicates the integrity of the
code when analyzed by a qualified service technician.
RS232 Electronics industry standard for serial communications
RTS/CTS Request To Send/Clear To Send
Handshaking protocol in which an RTS signal generated by the
Analyzer indicates there is data to send and a CTS signal generated
by the peripheral device indicates it is ready to receive data from the
Analyzer
