Description

The MIM-20 is a portable device that measures the maximum inspiratory pressure (MIP) a patient can generate through the oral cavity. It is connected to an analog or digital manometer, which records the pressure measurements in centimeters of water (cmH₂O).

Data Analysis and Use

MIP measurement data from the MIM-20 can be used for:
Diagnosis: Assessing the functional capacity of respiratory muscles and diagnosing neuromuscular disorders.
Monitoring: Evaluating the progression of diseases that affect the respiratory muscles and tracking the effectiveness of therapeutic interventions.
Research: Studies related to respiratory muscle physiology and the development of new therapeutic approaches.

Objective

The primary objective of using the MIM-20 is the accurate measurement of MIP, which provides critical data for evaluating respiratory muscle strength. This can assist in identifying potential disorders, designing appropriate rehabilitation programs, and assessing treatment progress.

Calibration

Calibration of the MIM-20 is essential to ensure measurement accuracy. This is typically performed using a known pressure source or a recognized calibration standard. The calibration process should be repeated regularly, according to the manufacturer’s instructions, to ensure the reliability of the measurements.
