The following items can be set from the USER IBP window:
1. Labels for both waveform and scale
2. Scaling,
3. Offset,
4. Scale adjust step size
5. Signal gain
The waveform and scale labels are set real time. They appear on the monitor display
as they are being entered in the USER IBP window.
The analog to digital converter (ADC) has 1024 bits. The user can select the scaling
and offset between the ADC scale and the displayed scale. The displayed max and min
scaled values can be changed by right and left clicking the values on the monitor
display.
The step size for this adjustment is set in the Range Adjust Step Size box.
Two gain stages allow overall signal gain to be set between 10 and nearly 5,000.
User IBP gates are automatically generated for the User IBP waveform. The presence
of gates generates values for User IBP rate and period. The gates can be displayed on
the respiratory sweep display and included in the algorithm for generation of output
gates.
AUTO EVENT window for time stamping
Left click the Event key to manually log an event in the trend file. Right click the Event
key to open the AUTO EVENTS window. The auto events feature allows pulses on the
Auxiliary Input to be counted and automatically logged in the trend file. The Auxiliary
Input can be either the AUX IN or the FO AUX IN on the ERT Control/Gating Module. A
FORT Module can be used to convert an electrical (TTL) signal to an optical signal for
input into the FO AUX port (refer to Chapter 3). The event can be triggered from either
the rising or falling edge of the pulse.
When enabled, the Auto Event Counter will either increment or decrement from the
Start Count value to the Stop Count value. If the window is closed it will reappear when
the Current Count reaches the Stop Count. An audible alert can optionally be issued
when the Current Count reaches the Stop Count.
continue counting when the Stop Count is reached. The Apply key sends entered data
to the counter software. The Restore key restores the last applied entry.
Note the user can set the Start Count, Stop Count and Current Count to create a non
terminal state. To eliminate this condition make certain the Current Count can either
increment or decrement to the Stop Count value.
