PDX Instructions for Patient
- The equipment you have been issued with has your details already programmed into the device.
- Please remove any nail varnish or acrylic nails prior to performing the test.
- We ask you to wear the device over clothing, for example a Pyjama top or a clean t shirt so that it is not next to your skin.
- The majority of the sensors should already be connected for you.
- Please do not smoke while wearing the equipment.
- Please take you medication as usual, unless instructed to do so.
- Be aware we need at least 4 hours for a study to be valid.
Set Up
- Connect the Belts
- Clip the chest band together, the recording device & cradle will be in the middle of the chest. Ensure the belt is not twisted.
- Clip the abdomen band together. Ensure the belt is not twisted.
- Both belts should be snuggly fitted but not uncomfortable. Adjust them accordingly.
- Turn the PDX On.
- On the top of the device slide the catch to your right, the screen will open.
- Press the power button and wait until the person appears on the screen, the signals will flash for a short period showing where all the sensors need to be placed.
- Connect Effort Sensors
- Plug the black leads into the small gold prongs on either side of the effort belt buckles.
- Put the other end of these wires into the corresponding icon. Do not mix up the chest and abdomen wires.
4. Connect The Cannula
- Loop the cannula around the ears and under your chin. The nasal prongs should be facing upwards inside the nostril. Adjust the slider under your chin to secure it into place. Tape the cannula to your face to secure it further.
- Screw the cannula into the top of the PDX, turning clockwise to secure.
5. Connect the Finger Probe
- Place the finger probe onto any finger (the finger nail should not have nail varnish or acrylic nail on).
- The cable will rest on top of the finger and along the back of your hand.
- Tape the wire to you hand to secure it into place. Please do not place any tape around the finger probe.
- Connect the finger probe wire into to PDX Device in the Sp02 port
- The connector from the finger probe slides onto the belt to stop it getting tangled.
Once everything is in place the device & you should look like this:
- Set up Complete
- All the sensors on the screen should have stopped flashing, if they continue to flash, the sensor is not connected properly, recheck and adjust.
- Close the PDX device up, on the top of the device the light should turn from amber to green.
- The green light will disappear quickly but the device will still be running.
- Go to bed – Please sleep in you natural sleeping position.
- If you need the toilet during the night, leave the device running but remove the finger probe to wash your hands.
Troubleshooting
During the night if you wake and notice an amber light flashing, open the PDX device and view on the screen which sensor is flashing, adjust the sensor that is indicated until it stops flashing, close the device and continue with the study.
If you have adjusted the sensor to the best of your ability and it continues to flash please continue with the study as we may have enough data, but be aware we may have to ask you to repeat the study at a later date.
