Description

Our GM Instruments Peak Nasal Inspiratory Flow (PNIF) Meter can be used to quickly assess the patency of a patient’s nose. It can be used with either a disposable or reusable mask.  A single use/disposable mask is included as standard with the unit. (One size fits all)

If the PNIF is to be used by a number of subjects, it can be cleaned between uses or alternatively, this can be avoided by siting an antiviral filter between the mask and the PNIF device. A clean mask should be used for each test.

If the PNIF is to be used by only one subject there is no need to change or clean the mask and no need to clean the PNIF or use an antiviral filter

It uses a variable diameter tube calibrated directly in litres per minute (l/min), along with a low inertia indicator ring, whose position after an inspiratory maneuver clearly indicates the maximum flow achieved.

It is recommended that an average reading of the best of 3 maneuver’s should be recorded for a subject as care must be taken to allow for variability in subject effort, and the possible effect of nasal valve collapse.

Accuracy: Plus/Minus 10% of reading or 10 L/min flow (whichever is the greater)
Repeatability: Plus/Minus 5%
Measuring: Average of 3 readings
Working Life: Replace after 2 years
