Start PNIF Test
  1. 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.
  2. Have the patient clear/blow their nose. If it's a baseline test for congestion, do not use sprays or rinses.
  3. In a standing position, have the patient fully exhale.
  4. Hold the meter horizontally.
  5. With the lips sealed and an airtight seal between the nose and mask, inhale forcibly through the nose.
  6. The PNIF technique should be a short and quick inspiratory flow lasting about 1 second in duration.
