Chapter 5 Test and Material List
5.1 Test
Procedure
5.1.1 Connection and Checking
Connect the simulators, power supply and test fixture properly to the PM-7000, and power
it on. Then, the patient monitor displays the start-up screen on the TFT screen and enters
the system screen.
5.1.2 Functions of Buttons
Press every button on the button panel to check their functions as specified in
PM-7000
Patient Monitor Operation Manual
. Rotate the control knob to check its functions.
5.1.3 ECG/RESP
The TFT screen displays the standard ECG waveform, and the error between the heart
rate and the set value of the simulator is no more than ±1, namely 60±1; the RESP
waveform is smooth, and the respiration rate is 20±1.
1. Select all leads in order, including
Cal
, select all the four gains and
AUTO
, ensure
the waveforms are displayed properly, and check whether the 50Hz/60Hz
interference can be filtered.
2. Check, in all the above-mentioned cases, the consistency between the
heartbeats, the flashes of the red heart-like indicator, and the R-wave.
3. The gain has no impact on the message “ECG signal over weak” in the HR
calculation.
4. Verify the range and precision: Suppose that the amplitude of the GCG signal of
the simulator is 1mV, the heart rates are respectively 30, 60, 120, 200, 240 and
300. Check leads I, II and III. The results should meet 29-31, 59-61, 119-121,
198-202, 238-242, and 297-303.
5. PACE pulse test: Set the simulator to PACE. You should be able to view the pace.
Change PACE amplitude to ±8 – 700mv, and pulse width to 0.1ms – 2ms. The
PACE should be legible, and LEAD OFF is displayed properly.
6. RESP measurement: Set the baseline impedance to 1K, the respiration
impedance to 0.5
Ω
and 3
Ω
, and the respiration rate to 30 and 120. The
respiration rate should be 29 – 31, 118 –122.
7. PVC test: Set the simulator to the PVC mode, and set the occurrence times. The
relevant PVCS should be obtained.
8. Set the simulator as follows: RR: 40, baseline impedance: 2K
Ω
, RESP waveform:
3:1. Open the apnea alarm, set the respiration resistance to 0
Ω
, and set various
alarm time. Alarms should be given.
