Page 14 of 19



ELO20210108N.00



Squeeze the demonstration lung hard during inspiration. Verify that the High pressure alarm is activated, the ventilator cycles into exhalation, and pressure falls to the PEEP/CPAP level. 11.1.2 Low minute volume Let the ventilator deliver 10 breaths with no alarms. Adjust the minimum ExpMinVol alarm limit so it is higher than the measured value. Verify that the Low minute volume alarm is activated. 11.1.3 Low oxygen alarm Set the Oxygen control to 50%. Wait for 2 minutes. Disconnect the oxygen supply. Verify the following:  



The oxygen concentration displayed in the monitoring window decreases. The Low oxygen alarm is generated.



Wait for 30 seconds or until the oxygen concentration falls below 40%. Reconnect the oxygen supply. Check that the Low oxygen alarm resets. The alarm should reset when the measured oxygen exceeds 45%. 11.1.4 Disconnection on patient side Disconnect the demonstration lung during active ventilation. Verify that the Disconnection on patient side alarm is activated. Reconnect the demonstration lung. Verify that the alarm resets and that the ventilator automatically resumes ventilation. 11.1.5 Loss of external power With the ventilator connected to AC power, turn it on. Disconnect the power cord. Verify that the Loss of external power alarm is activated and that the ventilator is powered by its backup battery. Reconnect the ventilator to AC power. Verify that the alarm resets and that the ventilator is again powered by AC. 11.1.6 Exhalation obstructed Block the expiratory valve exhaust port during active ventilation. Observe the pressure rise.

ELO20210108N.00



11.1.7 Apnea Put the ventilator into SPONT mode. Make sure Apnea backup ventilation is disabled. Wait for the set apnea time. Verify that the Apnea alarm is activated. Squeeze the demonstration lung. Verify that the Apnea alarm resets.



12 General tests Switch on the HAMILTON-C3 and stay in Standby mode. Connect the HAMILTON-C3 to the AC mains power and to the DC power supply. Perform the following tests:



12.1 AC — DC test Disconnect the AC mains power. Verify that the unit continues to run on the DC power supply and that the DC symbol is displayed on the screen.



12.2 DC — Battery test Disconnect the DC power supply. Verify that the unit continues to run on internal battery power and that the battery symbol is displayed on the screen. Verify that the alarm speaker sounds correctly for at least one minute.



12.3 AC — Battery test If no DC power supply is available, disconnect the AC mains power and verify that the HAMILTON-C3 switched to internal battery power. Verify that the alarm speaker sounds correctly for at least one minute.



12.4 Power loss test and buzzer test Remove the internal batteries. Verify that the unit alarms for at least 2 minutes. Caution: The buzzer is powered by the gold caps (super capacitors) on the mainboard. Make sure the unit is switched on (Standby mode or Service mode) for at least 20 minutes before the test to ensure that the gold caps are fully charged. Replace the mainboard if the buzzer sounds for less than 2 minutes. Reconnect the internal batteries and verify that the unit starts up again.



13 Fan check In order to check the fan for proper assembly, place a piece of paper over the fan inlet. If the paper sticks while the ventilator is on, the fan is blowing into the ventilator correctly. HAMILTON-C3 Service software



Page 16 of 19



ELO20210108N.00



14 Communication interface test The following material is needed to check the interface with the Hamilton Medical Datalogger software:    



Laptop with Windows operating system Datalogger software from Hamilton Medical USB to RS232 converter RS232 null modem cable



Ensure there is proper communication with the patient monitoring system. Alternatively, you can check the signal availability with the Datalogger software as shown in this video. Connect the laptop with the cabling to the serial interface of the ventilator. Set up the HAMILTON-C3 ventilator as for normal ventilation, with a complete breathing circuit and 2-liter demonstration lung assembly with an ET tube. Press Enter to start the Datalogger on the laptop. Start ventilation on the ventilator. Check that that the laptop is receiving and displaying the data sent from the ventilator. Stop the ventilation and disconnect the cabling. For more information about the Datalogger software, check the resources available on the Hamilton Medical website.



15 CO2 sensor accuracy check Follow these steps to check the accuracy of the CO2 monitor if installed. In addition to the HAMILTON-C3 ventilator with the CO2 monitor installed, this check requires: • • • • • • •



Patient breathing circuit Test lung CO2 sensor CO2 adult airway adapter Barometric pressure gauge (mbar) or TSI CO2 calibration gas cylinder or equivalent (CO2 5% ± 0.03; O2 0% ± 0.03; N2 Balance) CO2 gas regulator



Start the ventilator in Service software. Enter the Service software -> Tests/Calib > Sensor data > Sensor 3. Note the displayed barometric pressure (pressure sensor Pambient) and verify that it is within ± 20 mbars of the actual barometric pressure, measured with a second gauge or device (e.g., the TSI Flow Meter). Restart the ventilator in operational mode. Enter the Configuration menu: Tools > Configuration. Activate the CO2 hardware option: Tools > Configuration > Options > HW options. Connect the CO2 sensor with the CO2 communication board. Activate the CO2 sensor and deactivate the oxygen sensor: System > Sensors On/Off.



HAMILTON-C3 Service software



Page 17 of 19



ELO20210108N.00



Wait for 3 minutes to allow the sensor to reach the working temperature. Select the System tab, Tests & calib, then CO2 sensor to start the CO2 sensor calibration. Connect the patient breathing circuit, test lung, CO2 sensor, CO2 adapters, CO2 calibration gas and CO2 gas regulator. Set Oxygen to 21%. Start ventilation with standard settings. Select the PCO2 curve for displaying on the screen. Open the CO2 regulator slightly so that the display shows a stable CO2 curve. Note: Only a small regulated gas flow is required to achieve a stable curve. To achieve a stable CO2 reading, ensure that the CO2 sensor and CO2 adapters are upright. To see the PCO2 value in mmHg, press the Freeze button. See the corresponding graphs based on ambient temperature in the Service Manual. Confirm that the measured value is within the tolerance. Disconnect the sensor.



16 SpO2 measurement check Follow these steps to check the SpO2 measurement, if installed. In addition to the ventilator with the SpO2 communication board installed, this check requires: • • • •



Patient breathing circuit (not required: humidifier, water traps, or inspiratory filter) Test lung SpO2 Sensor Masimo OR SpO2 Sensor Adapter Nihon Kohden SpO2 finger probe



Check if the communication board is installed: • •



Enter System > Info. Verify the SpO2 communication board is displayed in the Info tab.



Activate SpO2 Sensor in Options: • •



Enter Tools > Configuration (Code 7132) > Options > HW options. Activate the SpO2 sensor.



Choose the installed sensor type (Masimo or Nihon Kohden) • •



Enter Tools > Configuration > Sensors. Choose the installed sensor type.



Activate the SpO2 sensor in the system: • •



Enter System > Sensors. Activate the SpO2 sensor.



Connect the patient breathing circuit with test lung. Connect the SpO2 adapter to the SpO2 port on the ventilator. Attach the SpO2 sensor to the finger probe. Start ventilation. HAMILTON-C3 Service software
