A teething apparatus includes a water-resistant housing containing a controller and a power source and communication means and a plurality of sensors in communication with the surface of the housing arranged and configured to detect at least pH and at least one volatile organic compound. Each of the plurality of sensors is in data communication with the controller and the controller is capable of communication with an external device via communication means. The apparatus may be a component of a larger system and may be used in a method including the steps of providing a teething apparatus to an oral cavity of an infant, establishing a data connection between the teething apparatus and a remote device, and relaying information from the teething apparatus to the remote device, the information comprising the qualitative measurement of one or more volatile organic compounds and the quantitative value of pH in the oral cavity.

An apparatus for testing for streptococcal pharyngitis includes a tube having an open first end and a second end, and an opening on a side thereof, a dipstick inserted into the tube through the side opening, and an insert with a hole that can receive the dipstick and sized to nest the dipstick into the side opening of the tube. A swab at the end of the dipstick inside the tube receives microbes in a breath exhaled by a patient holding the first end of the tube to the patient's mouth. After being exhaled upon by the patient, the dipstick is removed for testing for the presence of microbes that cause streptococcal pharyngitis.

A patient support apparatus, such as a bed, cot, stretcher, or the like, includes a frame, a support surface, an emitter, a detector, and a controller. The emitter and detector are coupled to the patient support apparatus at first and second locations, respectively. The emitter is adapted to emit electromagnetic waves in a direction aimed toward the detector. The detector is adapted to detect the electromagnetic waves emitted from the emitter. The controller is adapted to perform a spectral analysis of the detected electromagnetic waves to determine a parameter associated with the gas exhaled by a patient positioned on the patient support apparatus. The parameter may refer to a carbon dioxide level of gas exhaled by the patient, the patient's respiration rate, the patient's metabolic rate, or the like. The emitter, detector, and controller may alternatively be separate from, but attachable to, and in communication with, the patient support apparatus.

Pressure support therapy is provided to a subject. The effectiveness of the provided pressure support therapy is determined and/or the therapy is titrated based on determinations of the concentration of one or more gaseous molecular species in gas exhaled by the subject. The determinations of composition of gas exhaled by the subject are obtained from samples with relatively little distortion caused by dilution of expired gases from gases provided to the airway of the subject as part of the pressure support therapy.

A mouthpiece for a device for measuring analytes in exhaled air includes a gas path configured to convey exhaled air to the device and a film arranged so as to block the conveying of the exhaled air through the gas path. A system, in one embodiment, includes the mouthpiece and a device configured to measure analytes in the exhaled air. The mouthpiece is configured to be releasably connected to the device. The device includes a pressure sensor and, in one embodiment, a pump configured to pump air via the mouthpiece when connected to the device. The device is configured to be enabled to measure predefined analytes in the exhaled air when a pressure curve measured via the pressure sensor satisfies one or more predefined conditions.

Approaches to determining a sleep fitness score for a user are provided, such as may be based upon monitored breathing disturbances of a user. The system receives user state data generated over a time period by a combination of sensors provided via a wearable tracker associated with the user. A system can use this information to calculate a sleep fitness score, breathing disturbance score, or other such value. The system can classify every minute within the time period as either normal or atypical, for example, and may provide such information for presentation to the user.

A newborn respiration monitoring system includes a flow sensor that measures a gas flow and a CO.sub.2 sensor that measures a CO.sub.2 within the breathing circuit for an infant. The system further includes a resuscitation module executable on a processor of a computing system to receive the flow measurement and the CO.sub.2 measurement and determine respiratory information for the infant. A digital display is communicatively connected to the computing system and displays the respiratory information.
