Study Notes
- This tutorial details performing a Short Self Test (SST) on the Puritan Bennett 840 ventilator.
- Before starting, ensure the ventilator is plugged into the wall and connected to oxygen.
- The ventilator should have the tubing with the Y connector attached.
Initial Setup and Error Handling
- The ventilator may initially display a "short self test not allowed after patient connection" error.
- This alarm can be silenced by pressing the silence button.
- The error typically occurs when the Y connector is attached.
- Remove the Y connector prior to beginning to resolve the error, then select the short self test option.
Starting the Short Self Test
- Initiate the SST by pressing the test button on the side of the ventilator.
- The default patient setting is adult; press accept to continue and start the test sequence.
Step-by-Step Testing Procedure
- The ventilator provides instructions in the lower right corner of the screen.
- Prompts will guide you to connect the circuit, block the Y, and connect the humidifier.
- Connect the circuit and press accept to proceed.
- Block the Y connector by reattaching it, and then press accept to start the test.
- The total test time is approximately 5 minutes.
Testing Stages
- The ventilator conducts tests on the flow sensor, pressure, and circuit leak.
- The flow sensor test is performed first.
- The user is then prompted to connect the humidifier and press accept.
- After verifying the humidifier, the ventilator tests for circuit leaks, monitoring for any leaks.
Disconnecting and Reconnecting Tubes
- During the test, the ventilator will prompt disconnection from the patient port.
- Disconnect the indicated blue tube located by the expiratory filter.
- Incorrectly disconnecting a tube will cause the test to fail, and it will need to be repeated.
- After disconnecting the correct tube, press accept, then reconnect it and press accept again.
Final Steps and Completion
- The ventilator tests circuit resistance at this stage.
- Instructions will include unblocking the Y, then blocking it again, and finally unblocking it.
- The ventilator displays "SST testing is completed" when finished and indicates if all tests passed.
- Press accept to exit the SST.
- The ventilator is safe to connect to a patient after successfully completing the SST.
