A capnography system includes a CO.sub.2 sensing system having a CO.sub.2 sensor configured to measure a CO.sub.2 concentration in exhaled breath of a subject, a processor configured to derive one or more breath related parameters based on the measured CO.sub.2 concentration, and a communication unit. The capnography system includes a tubing system configured to allow flow of respiratory gasses therethrough. The tubing system includes a connector configured to connect the tubing system to the CO.sub.2 sensing system and a communication component configured to provide an indication of a type of the tubing system to the communication unit. The communication unit is configured to transfer data to the processor based on the indication obtained from the communication component, and the processor is configured to change or suggest a change of an operation mode of the CO.sub.2 sensing system based on the data.

An incentive spirometer is disclosed having a helical tube, wherein the helical tube includes a first inlet, second outlet, third outlet, and fourth outlet. The spirometer further includes a chamber, wherein the chamber is in fluid communication with the first inlet, second outlet, third outlet, and fourth outlet of the helical tube; and an object disposed within the spirometer, wherein the object is adapted to move through the first inlet of the helical tube and through either the second outlet, third outlet, or fourth outlet. In addition, the spirometer further includes an inhalation draw tube in fluid communication with the chamber and helical tube.

Described here are positive airway pressure (PAP) systems and methods with various mechanisms for altering the air pressure based in part on the head position of the user. This can be achieved actively or passively. Passively, pressure is altered when head position is altered, as gravity acts to open or close venting elements. Actively, head position information can then be communicated to a controller of the system which may be disposed within the housing having the position sensor or within a separate housing. The controller varies the output pressure of the pressure source, e.g. a rotary compressor, based, at least in part, on the head position information provided.

Disclosed is a device for counting the number of inhalation while medicine bottle is inserted into an inhalator, or measuring breathing capacity while medicine bottle is not inserted. The device includes a shell body, a roller, magnetic pieces, a sensor, a blue tooth integrated circuit (IC), a battery unit, and a circuit board. The roller is provided in the shell body, the magnetic pieces are attached onto the roller, and the circuit board is fixed on the shell body. The battery unit supplies electric power. When medicine agent is sprayed from the medicine bottle or the shell body is blown, the roller to rotate, the magnetic pieces synchronously rotate, and the sensor detects variation of a magnetic flux. The blue tooth IC calculates the number of inhalation when the medicine bottle is connected, or calculates breathing capacity of the user when the medicine bottle is not connected.

An incentive spirometer is provided that allows a user to achieve Sustained Maximal Inspiration (SMI) through the use of helical tubes. Specifically, the incentive spirometer includes three chambers, wherein each chamber includes a ball traveling upwards through three helical tubes in sequential order and subsequently dropping down through a basket. Here, each of the helical tubes and corresponding baskets generally represent various levels of lung capacity achieved with repetitive use and operation of the incentive spirometer.

An electronic incentive spirometer has a base and a sensing device. The base is provided with a breathing tube and at least one vertical tube. A floating ball is disposed in the vertical tube, one end of the vertical tube connected to the breathing tube. The sensing device is disposed on the vertical tube of the base, has a sensing unit corresponding with the vertical tube and a control circuit, and the sensing unit is electrically connected to the control circuit.

An exercise device, comprising: more than one resistance adjusting inserts wherein said resistance adjusting inserts are selected to change the overall resistance a user exercises against; a chamber wherein one or more of said resistance adjusting inserts are capable of being inserted within said chamber; and an inlet to said chamber wherein the one or more of said resistance adjusting inserts are movable within the chamber by breath of a user. A method for exercising comprising: using an exercise device comprising a chamber capable of holding at least one resistance adjusting insert where the chamber has an inlet; selecting at least one resistance adjusting inserts from more than one resistance adjusting inserts; and, moving the selected inserts in the chamber by air pressure generated by a user directed through an inlet into the chamber.
