5: Performance Verification Performance Verification Procedures
170
3 Test the maximum output by generating a fixed pacing waveform on the HeartStart XL+ for
180 ppm @ 140 mA.
a Press the Pacer Rate soft key and use the Navigation buttons to increase the rate to 180 ppm.
b Press the Pacer Output soft key and use the Navigation buttons to increase the output to
140 mA.
4 Check the output on the defibrillator analyzer. The output should read 180 ppm and 140 +
14 mA.
Synchronized Cardioversion Test
This section describes how to check the synchronized cardioversion function.
NOTE: Whenever possible, Philips Healthcare recommends that clinicians perform synchronized cardioversion
procedures while directly monitoring the patient through the HeartStart XL+’s electrodes or lead inputs.
If clinicians use an external monitor as the ECG source, you must verify that the external monitor and
the HeartStart XL+ combination will deliver a synchronized shock within 60 ms of the peak of the
R-wave. Use a 1 mV QRS complex with a QRS width of 40 ms. This performance cannot be guaranteed
with all commercially available monitors.
Setup
1 Set up the defibrillator analyzer.
a Connect the ECG cable and the Pads cable to the HeartStart XL+.
b Connect the ECG cable to the analyzer.
c Connect the Pads cable to the analyzer.
d Set the analyzer to a sync. measurement, 1 mV amplitude, at some nominal rate (e.g., 60 bpm).
2 Set up the HeartStart XL+.
a Turn the Therapy Knob to 1-10 J.
b Press the Sync button. Check that a Sync message appears in the upper right corner of
Wave Sector 1.
Check Display, Shock, Print
1 Check the displayed waveform.
Verify that sync markers appear on the display, at or near the peak of the QRS complex. Adjust the
size of the displayed ECG as needed to view it more clearly.
TIP: To adjust the size of the displayed ECG, navigate the following menus:
Menu –> Displayed Waves –> select Wave1 or Wave 2 –> I, II, or III –> select size.
2 Check shock delivery.
a Select an energy of 6 J.
b Press the Charge button.
c Press and hold the Shock button until the shock is delivered (at next QRS).
d Verify on the defibrillator analyzer that the shock was delivered, and was 6 ± 2J.
e If the device is configured to do so, verify that it prints a strip with the correct information on it
(waveform, text, shock).
f Verify on the defibrillator analyzer that the delay between the peak of the QRS and the delivered
shock was <
30 ms.
