MicroRPM Pressure Meter

MicroRPM Pressure Meters

Simple tests for respiratory muscle strength
The MicroRPM (Respiratory Pressure Meter) brings together the measurements of Maximum Inspiratory and Expiratory Mouth Pressures (MIP/MEP) with Sniff Nasal Inspiratory Pressure (SNIP) in one instrument.
These simple non-invasive tests of respiratory muscle strength are essential in monitoring patients with COPD who are undergoing a program of lung rehabilitation and are also valuable in the detection of other diseases affecting the function of the respiratory muscles.
Simple and easy to use, the pocket sized, battery operated MicroRPM features a clear digital display of the results in cmH2O and comes complete with all accessories in a sturdy carrying case.
Also offered, is the optional PUMA PC software. PUMA is a comprehensive analysis and database software package.
