CARESCAPE ONE User Manual DRAFT 26 October 2017
Invasive pressures
Whenever the patient's position is changed.
￭
Whenever the pressure reading is questionable.
￭
Pressures can be zeroed individually by selecting Zero in the pressure menu. You
●
can zero all pressures except ICP by selecting Zero All Pressures in the main menu.

Zeroing the invasive pressure transducers

1. Level the transducer following your care unit's policy (usually level of the
phlebostatic axis).
2. Close the transducer stopcock to the patient and open the venting stopcock to air.
3. If the pressure line you are trying to zero does not have the transducer open to air,
the message Pressure Sensed displays.
4. You can zero all connected pressure transducers simultaneously by selecting
Zero All Pressures from the main menu, or you can zero a single active pressure
transducer by selecting the invasive pressure parameter window > Setup > Page
1 > Zero.
NOTE
5. Check that a zero reference has been established. Watch the pressure parameter
window for messages.
6. Close the venting stopcock to air and open the transducer stopcock to the patient.
7. Check that pressure numerics display on screen.

Selecting an invasive pressure channel label

1. Select the invasive pressure parameter window.
2. Select Setup > Page 1.
3. Select a channel label from the Label list.
The channel label PA can only be used for one channel label. All other labels
names can be used for more than one channel label, if desired.

Selecting the size of the invasive pressure waveform

1. Select the invasive pressure parameter window.
2. Select Setup > Page 1.
3. Set the waveform scale with the Scale arrows.
The larger the scale value, the smaller the waveform size.

Optimizing the invasive pressure waveform scale

You can select an automatic calculation for an optimized waveform size. This size will
then be used for the waveform.
168
Zero All Pressures does not zero a connected ICP channel.
The ICP channel must be zeroed separately. When the
Zero ICP separately message displays, you can zero the
ICP channel by selecting Zero from the ICP Setup > Page
1 tab.
