The present invention provides a pneumonia detection device for detecting an exhaled air of a patient to determine whether the lungs of the patient have been infected by at least one bacterial species. The device comprises a multi-gas sensing module, a temperature and humidity control module, and an operation control unit. The multi-gas sensing module comprises a gas sensor array reacting with a gas metabolized from the bacteria to generate a plurality of characteristic signals. The temperature and humidity control module controls and measures an operational condition of 45° C.-60° C. and humidity between 7% and 20% for the gas sensor array. The gas sensor array contacts with the exhaled air to generate a plurality of measurement signals. The operation control unit comparisons the measurement signals and the characteristic signals of different bacteria to generate a result determining whether the patient has contracted the bacteria.

Disclosed are biofeedback methods and devices suitable for providing biofeedback useful for helping a user control an own breathing, for example, to help in inducing deep breathing, and such biofeedback devices further comprising a dispenser for dispensing an inhalable substance.

A method for predicting an arousal level used by a computer of an arousal level prediction apparatus that predicts an arousal level of a user is provided. The method includes obtaining current biological information regarding the user detected by a sensor, and calculating a current arousal level of the user based on the current biological information. The method further includes obtaining current environment information indicating a current environment around the user, and predicting a future arousal level, which is an arousal level a certain period of time later, based on the current arousal level and the current environment information. Based on the predicted future arousal level, the method further issues a notification to the user, or controls an operation of a device.

Devices and methods for monitoring physiologic parameters are described herein which may utilize a non-invasive respiratory monitor to detect minor variations in expiratory airflow pressure known as cardiogenic oscillations which are generated by changes in the pulmonary blood volume that correspond with the cardiac cycle. These cardiogenic oscillations are a direct indicator of cardiac function and may be used to correlate various physiologic parameters such as stroke volume, pulmonary artery pressure, etc.

A respiratory therapy device that is adapted to matingly, frictionally connect with dimensionally standardized devices and device adaptors, that when combined, allow for respiratory treatments. It monitors the direction of the air and or medicament flow (gases) in the device and can visually report as well as record the number of PEP treatment events or the number of medicament administrations by utilizing at least one bidirectional motion sensor therein. It presents a resettable, visual indicator for each pulse of gas that passes along its interior passage as well as providing a stored and transmittable record of these pulmonary events. It has an energy saving mode that will only allow the unit to be powered for operation when it is being handled.
