Set Flow Rate - The rate of flow commanded by the host system. The actual flow rate must be

within +15, -20% of this setting.

Short Watertrap Receiver - A Welch Allyn OEM Technologies accessory that mechanically

interfaces the Welch Allyn OEM Technologies watertrap with the host system. The
short receiver positions into the host system leaving a large part of the watertrap
exposed externally. (See Long Watertrap Receiver.)

Sidestream Sampling - CO

2

analysis which is accomplished within a device. The patient’s

expired gas is aspirated from the airway and drawn to the device through a sample
line.

Simple Command - A host communication to the Module to request data or a status change.

Data is not sent with these commands.

Simple Response - The Module communication to the host in reply to a command.

Soft Fault - Condition that interrupts Module operation, including transmission of CO

2

waveform

and breath data packets, until the fault is cleared.

Software Reset - A specific command that clears the Module and returns it to its original mode

and EEPROM default configuration settings.

SS - Sidestream.

SS Components - Parts that comprise an entire sidestream system such as the pump, tubing,

fittings and watertrap.

SS System - An end-to-end method to measure the patients expired gas by aspirating a gas

sample from the airway and drawing it through a sample line to a measurement
device.

Standby Mode - Module mode that disables the source, pump and data packets. It is typically

used when a low power, standby state, is desired.

Status Response - Data packets from the Module that communicate sensor or Module status.

The status response also serves as an acknowledgemnet for mode commands.

Steady State Measurement - A continuous measurement of CO

2

taken without regard to patient

respiratory rate. It is normally used during calibration, or when monitoring the
presence of background CO

2

. Usually the breath data update is disabled during

steady state measurements.

System Fault - An error associated specifically with the Main Board.

Thermistor - A resistor that has a large nonlinear temperature coefficient of resistance. Typically

used for temperature measurement feedback.
