MicroRPM Pressure Meter

Micro Direct Respiratory Pressure Meter

The MicroRPM (Respiratory Pressure Meter) is a hand held instrument designed for rapid assessment of inspiratory and expiratory muscle strength

brings together the measurements of Maximum Inspiratory and Expiratory Mouth Pressures (MIP/MEP) with Sniff Nasal Inspiratory Pressure (SNIP) in one instrument.


Essential test for monitoring patients with COPD who are undergoing a program of lung rehabilitation. 

These noninvasive measurements of respiratory muscle strength are invaluable in monitoring patients with COPD, or those suffering neurological or muscular diseases that will affect respiratory muscle function.  The deterioration of respiratory muscles can lead to increasing levels of dyspnea, disability, and eventual dependence on mechanical ventilation.
