DATASCOPE SYSTEM 98
The following are highlights of the MAJOR changes associated with the new Datascope IABP.
CHANGES TO THE ECG AND ARTERIAL LINE OUTPUT CONNECTIONS AND DISPLAY:
When you plug an ECG or ARTERIAL line cable from the bedside into the back, you will notice a couple of major differences:
- There is one "OUTPUT" receptacle. If you plug a jack into this receptacle, you will be taking information that is measured by the Datascope "OUT" to the bedside, displaying it on the Space Lab monitor. There is really no reason to do this.
- There are two "INPUT" receptacles: one labeled ECG and one labeled pressure. Plugging into these receptacles brings tracings from the bedside IN to the Datascope screen.
We will automatically connect the IABP lumen arterial line to the Datascope transducer at the back of the pump. We will NO LONGER need to bring the Space Lab arterial pressure from the bedside to the pump. CONTINUE to plug the ECG cable into the back as a back-up trigger. Remember to ensure that the transducer is level with the right atrium.
Mount the IABP transducer on an IV pole positioned at the foot of the bed (do not leave mounted on the IABP as it is too difficult to accurately assess the level).
You will need to zero the Datascope transducer by opening the transducer to air and holding the "ZERO" button (right side of panel below, in green) for 2 seconds until you hear a "click" (If arterial pressures are not displayed along the right side of the screen, the transducer has not been zeroed).
With the previous pumps, anything plugged into the back of the Datascope would automatically became the dominant waveform. If skin leads and arterial pressure were both connected, a cable at the back would canceled out the Datascope display. THIS IS NO LONGER TRUE WITH THE SYSTEM 98.
System 98 will NOT automatically default to the cable waveform.YOU MUST ACTUALLY SELECT THE WAVE TO BE DISPLAYED ON THE FRONT PANEL AS FOLLOWS:
Look on the front of the console. There is a "boxed" area identified as "Patient Waveforms" with 4 keys (in mauve above):
Selecting the top left key toggles between the Datascope skin leads and the external leads (Space Lab ECG plugged into the back). You can tell where the ECG is being monitored by looking at the display. If the ECG Lead I, II, III, aVL, aVR, or V is displayed, the ECG is coming from the Datascope skin leads. If the word EXT (external) appears, the ECG is coming in from the bedside monitor.
You can change the lead by selecting the ECG lead/external. Once you have toggled through all of the leads, the selection will be "EXT for external. If the ECG cable is plugged into the back, the Space Lab ECG will be displayed. If there is no ECG cable, EXT will appear with a flat wave.
Note: If a lead is lost or the cable is disconnected, the ECG display will NOT default to the other source....you will need to manually change the source at the front.
The top right key is the pressure source. Selecting this toggles back and forth between the Datascope pressure (X Ducer) or the external source (EXT).
If you select and hold this key, the portion of the arterial line where the balloon will inflate and deflate is highlighted. Improved visibility is provided by vertical lines from the highlighted portion.
CHANGES TO PRINT MODE
To print, you must depress the "print" button on the far right side of the panel (below the zero button).
The printout characteristics are determined by the settings preselected from the printer menu. The printer menu is located in the user options box (below).
The bottom right area of the panel has a User Option box (in blue below). There are 6 options; you can select one of these options at a time. The option that has been selected will have a light illuminate beside the selection. The arrow up and down, "change/select" and "done" keys correspond to the selection that is currently highlighted. User options include reference line, augmentation alarm, alarm volume, preference menu, printer option and help.
When selected, a light will illuminate beside the preference menu. Use the up and down keys to scroll vertically through the menu. Use the change/select key to scroll horizontally across the options. Press done to confirm a change.
The printer menu allows you to define the characteristics of any printouts. You can also print trends and a history of past alarms.
If you press the help button during any alarm situation, an on-screen display of possible causes and solutions will be displayed. It can also be selected during the initial set-up of the pump to provide on-screen instructions.
The reference line, alarm volume and augmentation alarms remain unchanged.
The auto/manual timing and filling switches have been relocated to the bottom left front panel. To change modes, you must depress the option and hold for 2 seconds.
As with the previous pumps, ECG trigger should be used in most situations. Avoid the use of either pacemaker trigger as the patient must be in fixed rate pacing to work. In a cardiac arrest, continue in ECG trigger until the pump alarms, then switch to pressure mode. Pressure trigger is located in the top left corner of the panel (do not confuse pressure trigger with pressure source...pressure source switches between the Datascope and external arterial sources and is not related to the pressure trigger). CPR should provide a sufficient rise in pressure to trigger the pump.
When you change the trigger mode, you must re-select the assist button to resume pumping.
If the BP is low, you may decrease the pressure trigger (these reduces the size of the pressure rise that is needed to trigger the pump). To reduce the pressure trigger, ensure that the pump is in the pressure trigger mode. Select the arrow down key in the auxiliary box located below the trigger box. A small, horizontal line will identify the pressure threshold.
Internal is only used when the patient has no ECG or pressure. There is really very little role for this mode in viable patients; it may be used in the OR during cardiopulmonary bypass if pulsatile flow is desired.
Please note: LHSC no longer has the Datascope 98 available for use. At Victoria Hospital the Maquet CS 100 model of IABP is available for use.
