15. Measurement display screen
Measurement display screen – This screen will display the Eye
measured, the average reading and individual readings
from either the left (L) and right (R) eyes. Left and right
detection is automatic.
After the first reading is taken the display shows the
measured IOP. After each of the consecutive readings are
taken the display shows the individual reading and the
average of up to the last four 4 readings per eye.
In addition to IOP readings, the Pulsair Desktop also displays a
number of messages on the character display when a
measurement is not detected for a number of reasons. In
such cases, the display may read as follows:
a) < 5: This is shown when the reading is lower than 5mmHg, in which case no
valid reading is displayed. (Signified by long sound)
b) >25: This is shown when applanation is detected
with soft-puff and the reading is greater than
25mmHg, in this case the instrument displays >25
and switched to hard puff. The instrument shall
stay in hard puff until two consecutive readings are
less than 20mmHg.
c) >50: This is shown when the reading is greater than 50mmHg, in which case
no valid reading is displayed. (Signified by long sound)
Note: The displayed dummy average is rounded to the nearest whole number or
displayed to one decimal place depending on the user setting accessed via the menu.
The displayed running average is based on the actual readings
which are taken to one decimal place. For example, readings of
15.4, 16.3, 14.2 and 16.9 are averaged by adding them together
which equals 62.8 and dividing by the number of readings taken, 4.
This gives a final figure of 15.7, or 16 depending on user settings.
Please note independent readings are displayed as whole numbers.
When all the required readings have been taken the figure
displayed is the IOP that is recorded for the patient. When two
consecutive readings are within 1mmHg
an audible sound will be heard indicating
that sufficient readings may
have been taken.
