Study Notes
Pre-Use Check on the PB 840 Ventilator
- A pre-use check, also known as a short self-test (SST), is performed on the PB 840 ventilator as explained.
- The ventilator must be connected to a power source and gas wall outlets prior to the self-test.
- To ensure stability, the ventilator's wheels should be locked.
- The circuit's blue protective cap should be taken off before running a self-test
Orientation to the Ventilator
- The on-off switch is protected by a plastic cover.
- The test button can be found behind the power cord on the left side.
- The test button has to be pressed within 5–10 seconds of turning on the SST in order to work.
- The ventilator screen shows data and has sections for programming ventilation dynamics.
- The lower right corner has instructions, including how to perform the self-test.
- A knob enables users to change values or scroll through menu options.
- Clear and accept buttons: clear voids the programming you're about to make and accept, accepts the value you have selected
Starting the Self-Test
- The bottom menu displays "Same Patient," "New Patient," and "SST Short Self-Test" when the ventilator is turned on.
- To begin the short self-test, highlight and choose "SST".
- To confirm any option chosen, the button needs to be pressed.
- The ventilator will then ask what kind of patient circuit (adult) is being used.
- Choose the type of humidification.
- Establish a 290 Mini-Flow volume.
- To confirm settings, use the knob to adjust them and press "Accept"; to cancel, select "Exit SST."
Steps During the Self-Test:
- Connect the circuit with the inspiratory filter, bypassing the humidifier, and then press "Accept."
- Take the cap and block the patient Y, then press "Accept" to continue the test.
- Check all circuit connections to ensure they are tight before proceeding. A circuit pressure test follows this step
- Reconnect the humidifier to the circuit when instructed, then press "Accept" to move forward.
- On the screen, select "Accept" after disconnecting the adapter from the patient port.
- Before selecting "Accept" for the test to resume, reconnect the adapter to the patient port.
- When prompted, unblock the Y during the test and choose "Accept" on the screen.
- Press accept if there is water in the humidifier during the test
- When prompted, block the Y once more, then press the "Accept" button.
- To finish the SST, unblock the Y once more and choose "Accept".
Completing the Self-Test
- Once the SST is finished, there is a choice to "Restart SST" or "Exit."
- To continue, choose "Exit" and press "Accept" to confirm.
- The ventilator runs an electronics check after exiting.
Post Self-Test
- The ventilator goes back to the main menu when the self-test is finished.
- To begin setting up the ventilator in the desired mode for ventilating a new patient, select "New Patient".
