SNIP Test
Slide the MicroRPM switch from ‘Off’ to ‘SNIP’, whilst applying no
pressure to the Nasal Probe. Rotating segments will be displayed
whilst the unit performs an auto-zero function.
When the MicroRPM is ready a ‘beep’ will be heard and ‘0’ displayed.
To perform the test, instruct the subject to insert the chosen Nasal
Probe firmly into a nostril, whilst ensuring the other nostril remains
open throughout the test.
The subject should then breathe normally and at the end of a normal
tidal expiration, FRC (Functional Residual Capacity), be instructed to
perform a short, sharp voluntary sniffing manoeuvre with as much
effort as possible.
The display will report the result, the peak inspiratory nasal
pressure, in cmH2O.
On subsequent tests the MicroRPM will continue to display the
highest SNIP value, overwriting previous values. Ideally, the subject
should repeat this test 10-15 times to ascertain the highest value.
