Patient PNIF

Before each use, the cursor (red dial) on the Peak Flow Meter is reset to the zero [0] mark. To reset the dial, gently tap the bottom of the meter to have the magnetic weight dislodged, returning to the starting position.
Have the patient clear/blow their nose. If it's a baseline test for congestion, do not use sprays or rinses.
In a standing position, have the patient fully exhale.
Hold the meter horizontally.
With the lips sealed and an airtight seal between the nose and mask, inhale forcibly through the nose.
The PNIF technique should be a short and quick inspiratory flow lasting about 1 second in duration.

Disclaimer: This website is not a sole source in determining patient healthcare outcomes and should not be exclusive without a physical exam, patient questionnaire, patient interview of symptoms, or additional diagnostics completed by a licensed healthcare provider. The website is for information and educational purposes to show how nasal airway measurements allow the HCP to objectively quantify the patency of the nasal away and its part in airflow limitations. It is not medical advice, but based on evidenced based medicine, nasal aerodynamic studies, and validated research over 20+ years using the noninvasive technology methods. The noninvasive, objective nasal measurement processes do not diagnosis a breathing disorder, but allow the HCP to screen and understand how the treatment options are helping for better results towards nasal breathing. Additional questions and educational assistance on the methods, processes for results, and the theory of nasal aerodynamics may be sent through our website query.
