Respiratory muscle endurance training device and method for the use thereof

摘要

A respiratory muscle endurance training device (RMET) includes a chamber and a patient interface. In one implementation, one or both of a CO2 sensor or a temperature sensor can be coupled to the chamber or patient interface to provide the user or caregiver with indicia about the CO2 level in, or the temperature of, the chamber or patient interface, and/or the duration of use of the device. In another implementation, the RMET may have a fixed volume portion adjustable to contain a measured portion of a specific patient's inspiratory volume capacity. Methods of using the device are also provided.

1. A method of training a user's respiratory system comprising:
providing an adjustable chamber; determining a suitable interior volume of said adjustable chamber for a user; adjusting said adjustable chamber to said interior volume, wherein said adjustable chamber comprises an output end, wherein said adjusting said adjustable chamber comprises moving mating first and second chamber portions toward and away from each other; successively inhaling and exhaling a plurality of breathing cycles through a patient interface coupled to said output end without altering said interior volume; capturing expired gases in said interior volume during said exhaling through said patient interface and thereby increasing a concentration of CO2 in said interior volume; and reinhaling said expired gases from said interior volume through said patient interface.
