Detect Pace: Turns pacemaker
detection On/Off.
Two different options of
pacemaker modes are available. The clinician must judge which mode is best for each patient. Pace 2 is the recommended pacemaker detection mode. Pace 1 should be used if Pace 2 does not adequately detect pacemaker spikes.
To Activate or Deactivate the
Pacemaker Mode:
Select ECG.Select DETECT PACE.Turn the Trim Knob in
front of the desired pacemaker mode and press to select.
Select MAIN MENU to
exit.
NOTE: A P appears in the ECG parameter window when pace detection is enabled. An *” will appear if a paced beat is
detected.
Pace 2 Mode: Analyzes
waveforms with the added capability of minimizing the chance of counting severe residual pacemaker energy as a QRS complex. Pace 2 may not adequately detect all QRS morphologies. Arrhythmia calls such as Asystole or Pause may be made with heart rate identified as less than actual.
NOTE: Pacemaker patients should be kept under close observation.
TAB TRIM
COVER & NON-TAB TRIM
Pace 1 Mode: Analyzes the
presence of pacer spikes, assesses the waveform for residual pacemaker energy and determines the presence of an R-wave following the pacemaker spike. If an event occurs during the first few milliseconds following the spike, it will be counted as a paced spike.

Guidelines for Successful
Pacemaker Monitoring:
Multi-vector pace detection is
determined by simultaneous analysis of the displayed ECG Lead and the Vector Lead.
Adequate pacemaker
detection is directly dependant on the quality of the ECG waveform. Proper skin preparation and electrode placement are essential.
Ensure that the pace detection
mode is activated.
All detected pacemaker spikes
will appear upright, uniform and white on the display screen.
If the monitor is not
adequately detecting pacemaker spikes as evidenced by heart rate double counting, pacemaker spikes not detected, alarms for low heart rate or asystole it is recommended that you change the electrode placement to a recommended configuration.
After changing electrode
placement, always RELEARN the ECG waveform. If adjusting the electrode placement does not resolve the detection issue, change the pace detection mode to Pace 1 and RELEARN.

Monitoring:
Choose the probe that is best
suited for your patients needs: ear, finger, disposable, reusable, etc.
Clean the surface of the probe
before and after each patient use.
Following the instructions
provided with the probe, correctly position and attach the probe to your patient.
When a Masimo sensor is
repositioned at any time, disconnect the cable from the sensor before repositioning.
Reconnect the sensor to the
cable after proper patient preparation and placement.
SPO
2
It is Important to be Aware
of the Following when Monitoring SPO2:
A poor SPO2 signal may result
if the probe detector is exposed to strong ambient light.
When securing the probe,
ensure nothing is blocking the probe light detector.
Prolonged monitoring may
require changing the probe site periodically. Monitor the probe site. Move the probe if there is any sign of skin irritation or impaired circulation.
Change the probe site at least
EVERY FOUR HOURS to prevent skin breakdown. With neonate, you may need to reduce application periods to half the recommended time.

Invasive Pressures — IABP:
The IABP program
compensates for the irregularities in the pressure waveform caused by the use of an intra-aortic balloon pump.
To ensure that the trigger
signal is compatible with all modes of the IABP, the signal source used to trigger an intra-aortic balloon pump should be the pump itself.
If the trigger is from the
monitor, be certain that the manufacturer is compatible with the GE Medical Systems Information Technologies analog output signal.
If the trigger is off of the
R-Wave, review the patient’s ECG leads and place the one with the greatest amplitude in the display (top) lead position.
If blood pressure is used to
trigger the balloon, the first red pressure port labeled ART will be used.
Cable the balloon pump to
the monitor through the Defib Sync connector on the back of the monitor.

Displays:
Systolic Value = Highest
pressure in one cardiac cycle.

pause or inaccurate heart rate when a visible QRS is present?
Answer:
The monitor may not be seeing sufficient QRS amplitude in all analyzed leads. Multiple leads (I, II, III and V) are used for arrhythmia processing. For best results, a 1.0 mV amplitude in all analyzed leads is recommended.
Review the VIEW ALL ECG option to assess the
amplitude of the QRS complexes. A minimum of
0.5 mV amplitude in all analyzed ECG waveforms at normal size (1x) is required for QRS detection. For best results, a 1.0 mV amplitude in all analyzed leads is recommended. Amplitude is viewed in one direction (positive or negative). For borderline signals, validate the ECG waveform on a graph.
If the amplitude is low in any analyzed leads,
perform skin preparation and adjust electrode placement. When adjusting placement, utilize fresh electrodes.
Increasing the amplitude >2X when using the
ECG SIZE option is for the clinicians viewing
only. It will not affect the ECG analysis.
It may be beneficial to move the V-Lead

Invasive Pressures
TAB TRIM
COVER & NON-TAB TRIM
Problem:
Why do I have different values between my Arterial, Non-Invasive (oscillometric), and Non-Invasive (auscultated) BP readings?
Answer:
All three measurements use different technologies.
Intervention:
Auscultation and oscillometric are both INDIRECT
methods of measuring blood pressure. In auscultation, changes in arterial sounds during cuff deflation are related to systolic and diastolic pressure. In oscillometric, changes in measured pressure oscillations during cuff deflation are related to systolic, mean and diastolic pressures. Changes in the vascular tone of the arterial system can cause these two indirect methods to differ from one another AND from direst arterial pressure. Invasive Arterial Blood Pressure is a DIRECT method of measuring blood pressure. Differences are expected between direct and indirect measurements of blood pressure. These differences occur because DIRECT methods measure PRESSURE and INDIRECT methods measure FLOW. In addition, differences occur because the location of measurement used is generally not identical in both methods, i.e., brachial artery for NBP vs. radial artery for invasive pressure monitoring.
Problem:
Why is the monitor alarming DISCONNECTED?
Answer:
The arterial disconnect alarm found in the ART or FEM menu is on. If the mean pressure falls below 25 mmHg and the disconnect alarm is on, a warning alarm sounds and the message “DISCONNECTED” is displayed in the parameter window. When zeroing the line, the clinician has 14 seconds to complete the process. After that time period, the message and alarm will be activated.
Intervention:
If zeroing, close the stopcock. Once the monitor
detects the return of waveform and numeric data, the alarm will reset.
Check the patient immediately in the event the
catheter has been dislodged.
The DISCONNECT ALARM may be turned off in
the arterial menu. Remember to monitor the patient closely when turning this alarm off.

Problem:
Why does the monitor continue to read INFLATE
Problem:
Why is the invasive waveform overshooting the scales?
BALLOON after the balloon has been inflated?
Answer:
Answer:
The monitor must detect a 30% change in the waveform to measure a wedge. If the waveform does not change accordingly, the WEDGE PROCESSING message will not appear.
A new scale needs to be selected to accomodate the change of the pressure reading. If Auto Scale was previously selected, this would have used the current waveform reading as a reference when this function was requested. If the waveform readings have fluctuated, a larger range scale or reselecting Auto Scale will reset the scale for the current reading.
Intervention:
It would be recommended to complete a PA Wedge
utilizing the manual mode.
Problem:
When using a UAC, does it make a difference to label it as an ART instead of UAC?
Answer:
No, it does not. But remember when looking up the information under VITAL SIGNS or GRAPHIC TRENDS, no data will be found under the displayed label.

Problem:
What is the difference between the ZERO ALL hard key and the ZERO menu option under the invasive pressure (ART) parameter window?
Answer:
The ZERO ALL hard key on the front of your monitor will zero any invasive line that is open to air. So, if the caregiver would like to Zero one or multiple lines all at once, open the transducer to air, and select ZERO ALL hard key. If a transducer is closed, the text prompt “Pressure” will be displayed in that parameter box. If the caregiver is in an invasive parameter menu, the ZERO menu option will only Zero that transducer when it is open to air.
Problem:
How does the caregiver print out pulmonary artery wedge waveform without ECG waveform?
Answer:
Select the PA parameter box. Select GRAPH BP INVASIVE menu. Select and highlight PA. Then,
within the same menu, scroll up to select GRAPH. This function will print out a continuous strip of the invasive lines that were highlighted. On the top center of the screen, that text “BP Graphing” will be displayed as the graph is being generated. Proceed to perform wedge procedure. When adequate strip information has been obtained, select hard key GRAPH GO/STOP to terminate the graph.
