In exercise testing it is desirable to have an exercise protocol which helps to maximize the subject's ability to reach their peak workload. The exercise protocols taught here are designed to give exercise workloads which can be progressively graded and use natural cadences of walking and running to give a more comfortable pace at various workloads, and are performed over an adequate time. A lower extremity ergometry protocol method is also taught which gives a more accurate workload, and can help to minimize stress on the knees. This patent also teaches that ramping or workload for exercise protocols may be controlled by the physiologic response to the exercise. These protocols are also useful in exercise training and in rehabilitation.

A novel and non-obvious method, system and apparatus for determining respiratory volume flow rate of a subject and associated parameters such as tidal volume, minute volume, and respiratory rate. The method for determining respiratory volume flow rate of a subject can include selecting an airway cavity of the subject, measuring delivery volume flow rate of respiratory gas delivered to the airway cavity, measuring pressure within the airway cavity and calculating a respiratory volume flow rate of the subject using the measured delivery volume flow rate of respiratory gas delivered to the airway cavity and the measured pressure within the airway cavity. The method further can include generating a warning signal selected from the group consisting of an indicator that a respiratory volume flow value is outside of an expected value for the subject and an indicator that an airway cavity measurement value does not conform to an expected value.

A nasal cannula comprising: a base portion defining a gas passageway and one or more nozzles defining a second gas passageway in gaseous communication with the first gas passageway for directing a therapeutic flow of gas to a user's nares. The nasal cannula may include one or more sensors for measuring the properties of gas within a user's nares. The nozzle may be a nasal insert that is inserted into the user's nares; recesses or grooves are provided for preventing sealing of the nasal insert with the nare. The nozzle may be shaped to avoid insertion into the user's nares, thus preventing sealing with the nares. A stop may be positioned between two nozzles to engage a user's columella and prevent the nozzles from inserting into the user's nares. Elongate extensions are provided for inserting into the user's nares and supporting sensors for measuring gas properties therein.
