Abstract
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.
Claims22
A respiratory muscle endurance training device comprising:
- a patient interface for transferring a patient's exhaled or inhaled gases;
- a fixed volume chamber in communication with the patient interface, wherein the fixed volume chamber is sized to retain a portion of a patient's exhaled gases;
- a variable volume chamber in communication with the fixed volume chamber, wherein the variable volume chamber is configured to be responsive to the patient's exhaled or inhaled gases to move from a first position to a second position;
- an exhalation opening spaced from the patient interface and in communication between the ambient environment and at least one of the fixed or variable volume chambers;
- and
- a valve in communication with the fixed volume chamber.
A respiratory muscle endurance training device comprising:
- a patient interface for transferring a patient's exhaled or inhaled gases;
- a fixed volume chamber in communication with the patient interface, wherein the fixed volume chamber is sized to retain a portion of a patient's exhaled gases;
- a variable volume chamber in communication with the fixed volume chamber, wherein the variable volume chamber is configured to be responsive to the patient's exhaled or inhaled gases to move from a first position to a second position;
- a valve in communication with the fixed volume chamber;
- and
- a moveable cover disposed over said variable volume chamber.
A respiratory muscle endurance training device comprising:
- a patient interface for transferring a patient's exhaled or inhaled gases;
- a fixed volume chamber in communication with the patient interface, wherein the fixed volume chamber is sized to retain a portion of a patient's exhaled gases, said fixed volume chamber having a first variable size orifice communicating with the ambient environment;
- and
- a variable volume chamber in communication with the fixed volume chamber by way of an interface, wherein the variable volume chamber is configured to be responsive to the patient's exhaled or inhaled gases to move from a first position to a second position and wherein said interface comprises a second variable size orifice communicating between said fixed and variable volume chambers.
