PIF-CONTROL - THE BREATH SENSORY FEEDBACK SYSTEM

Slowing down reduces collisions not only in road traffic – in inhalation therapy as well, lower speeds help aerosol aerosol

particles to reach their intended delivery point more reliably, and not to crash in tight bends or become neutralised by impaction in the branches.
Breathing in slowly leads demonstrably to less deposition in the throat1 and better distribution of the aerosol aerosol

in the lungs2.
Simply by breathing at resting pace with a nebuliser during treatment, there is significantly less impact on the patient's throat cavity than during treatment with MDIs or DPIs1. Anyone who wants to make absolutely sure can now further improve the breathing manoeuvre quite easily with the specially developed PIF control system. PIF control is a breath sensory feedback system – when inspiratory flows exceed 25l/min, there will be the feedback signal that the patient is breathing in too quickly. The patient feels this as perceptible brake on his inspiratory flow inspiratory flow

. He must then modulate his breathing until the "brake" is released again and he can continue breathing without restriction.
