DESCRIPTION OF Peak Nasal Inspiratory Flow (PNIF) Meter - Peak flow meters

The In-check PNIF meter can be used to quickly assess the patency of the nose. Peak nasal inspiratory flow (PNIF) meter helps patients to care for their breathing health including main well-being functions such as swallowing, sleep quality, olfaction, paranasal sinus aeration, allergic rhinitis, the bronchial asthma and middle ear health.

How does Peak Nasal Inspiratory Flow (PNIF) Meter work?

It uses a variable diameter tube calibrated directly in litres per minute (in the range 30 to 370 l/min, with an accuracy of +/- 10% or 10 l/min), along with a low inertia indicator ring, whose position after an inspiratory manoeuvre clearly indicates the maximum flow achieved. The In-Check works when a patient inhales through the mouth or nose, this will cause air to be drawn through the meter and a cursor moves along the scale to indicate the speed of inhalation. The flow rate achieved can be noted by checking the position of the cursor against the calibrated scale. It is used along with either a disposable or reusable mask, both of which are available in either small or medium sizes. A medium disposable mask is included with the unit when delivered.
