10.2 Preparing the patient
Before using the Pulsair Desktop you should make your patient
feel at ease and ensure they are located in an optimum reading
location, preferably with their head supported. This is because
apprehension and nervousness may adversely affect the readings
obtained. Follow the points outlined below to achieve this:
1. Ensure that the patient is comfortable and in a relaxed
position.
2. Ask the patient to remove their contact lenses or spectacles if
worn and to blink and breathe normally.
3. In order to reassure the patient, you can demonstrate the
procedure, using the Demo button, on the back of the
patient’s hand prior to taking a reading.
4. Place disposable chinrest tissue on the chin rest.
Ask the patient to place their head on the chinrest.
5. Adjust the chinrest height so that the outer canthus is
aligned with the marker on the chin rest vertical support.
Before taking a reading you should:
1. Ask the patient to blink to ensure a good and reflective tear film.
2. Ensure the patient and instrument optics are not positioned
under direct lighting (i.e. spot lights or sunlight).
3. Ensure the patient’s eyes are fully opened. This helps to
prevent squeezing, where the patient unconsciously tenses
their eyelids and increases IOP.
4. Throughout the reading process, you should:
Allow the patient to blink at intervals in order to maintain
the corneal tear film.
