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.
FACTS. On the official website you can find some facts about accuracy and features of PEAK NASAL INSPIRATORY FLOW (PNIF) METER: http://www.alliancetechmedical.com/products/check-inspiratory-flow-measurement-device/
Have you known that:
• Each In-Check is individually calibrated to ensure a high degree of accuracy (+/- 10% or 10 L/min - whichever is greater)
• Inspiratory flow rates in the range of 30 L/min - 370 L/min can be measured
• US FDA 510k approved; conforms to international standards for peak flow meter performance
