Labeling Convention For Respiration Channels; User Input Channels - SA Instruments 1030 Operation Manual

boxes to increase or left click to decrease the sweep time. Note the cardiac and
respiratory sweep times are independent and can be set to different values.
Switch between ºC and ºF by clicking on the digits in the temperature display
Clicking on the speaker icon associated with the cardiac sweep activates an audible
beep for each ECG R-wave. Likewise clicking on the speaker icon associated with the
respiration sweep activates an audible beep for respiration. It is not intended for both
the ECG and respiration audio indicators to be on at the same time.
Grids can be turned off and on by left clicking inside a waveform display. Note the time
separation of the grid lines is displayed above the waveform.
Right or left clicking on the gray box next to the red indicator of the cardio or respiration
sweep gate displays will sequentially change the gate displayed. For the cardiac sweep
the most useful gates are ECG and R-detect + Blanking Time.

Labeling convention for respiration channels

Respiration waveforms, measured from ECG leads, and the associated gates are
labeled as "E-Resp" or ''EResp". Respiration waveforms, measured from a pneumatic
pillow, and the associated gates are labeled as "Resp" or "P-Resp". Waveforms and the
associated gates for the User Spare Analog Channel are labeled "UserR" or "User
Resp". Note that the "UserR" label can be changed in the User Spare Resp Setup
menu. (Refer to Chapter 10).

User Input channels

Up to four user auxiliary input channels are available, two digital (on/off) and two
analog. The digital channels are useful to synchronize gating with external equipment
such as a ventilator and/or to time stamp physiological measurements with an event
marker from the scanner (refer to Chapter 15). The analog channels allow user defined
waveform information to be input for recording, display and gating.
The digital auxiliary channels are input through the ERT Control/Gating Module at
"AUX" (TTL) and "AUX GATE IN" (fiber optic signal). They are digitized at 1800
samples/second.
The analog auxiliary channels are associated with the IBP Module. They are input at
"User Resp" and "IBP3". User Resp is digitized at one half the IBP rate of 900
samples/second. Refer to Chapter 10 for connector pin specifications and Chapter 15
for setup features.
