A computer-implemented method is described. The method includes receiving an indication and determining a subject's oxygen consumption based on the indication. The indication refers to an oxygen fraction in a sample of inhalation gas delivered by a ventilator for inhalation by a subject. The indication further refers to an oxygen fraction in a sample of exhalation gas exhaled by the subject. The indication further refers a measurement of a flow rate of the exhalation gas.

A mobile newborn care bed is configured to be positioned at a delivery location of an infant includes a bassinet containing a mattress for receiving the infant and a frame that supports the bassinet. At least two capacitive sensors are incorporated in the mattress that record cardiac signals, and an on-bed computing system is configured to receive the cardiac signals and determine a heart rate for the infant. A battery supported by the frame powers the on-bed computing system, and a digital display is communicatively connected to the on-bed computing system and displays the heart rate.

An apparatus that monitors information associated with an oral cavity is provided, the apparatus comprising: a three-dimensional oral appliance; a data collection device having at least one sensor and/or hydrogel like material configured to sense the information associated with the oral cavity; an interface device cooperatively coupled to the data collection device, the interface device configured to transfer the information from the sensor device to a receiving device external to the oral cavity or the entire device is analyzed.

A method, comprising receiving a time series of patient body signal, determining first and second sliding time windows for the time series; applying an autoregression algorithm, comprising: applying an autoregression analysis to each of the first and second windows, yielding autoregression coefficients and a residual variance for each window; estimating a parameter vector for each window based on the autoregression coefficients and residual variances; and determining a difference between the parameter vectors; and determining seizure onset and seizure termination based on the difference between the parameter vectors. A non-transitory computer readable program storage unit encoded with instructions that, when executed by a computer, perform the method.

An embodiment of the invention provides a wireless in-ear utility device that rests in the user's ear canal near the user's eardrum. The in-ear utility device may be configured in a variety of ways, including, but in no way limited to a smart in-ear utility device, a flexible personal sound amplification product, a personal music player, a “walkie-talkie” and the like.

The invention pertains to the establishment, implementation and management of a personalized information system pertinent to a user's general health, wellness and/or sport performance. Disclosed is a system capable of transcutaneous measurement of a subject including at least one light source, at least one light detector, and at least one component for generating or storing at least one value of VC02 or at least one value of V02 from the detected signal. Further, disclosed is a portable device for analyzing the composition of the respired gasses of a subject including at least one air flow conduit through which the subject can inspire or expire air through the body of the device, at least one sampling portal, an oxygen sensor, and at least one flow sensor. A dual-battery system is also provided by which an uninterrupted power supply can be provided for electronic components.

A method, system and computer program for predicting a VO2max measurement for a subject, the method comprising: collecting a heart rate recovery value, measured over a first period starting at the end of a fitness test exercise completed by the subject, wherein the fitness test exercise comprises a plurality of phases, each phase having a predetermined duration and each phase being associated with a respective heart rate band, and during each phase, the subject adjusts their effort to maintain their heart rate in the respective heart rate band, and calculating a predicted VO2max measurement using the heart rate recovery value.

Some embodiments are directed to determining the composition of breath exhaled by a subject. For example, some embodiments are directed to determining a concentration of a gas species in breath exhaled by a human subject, based at least in part upon a measured concentration of the gas species in a chamber which is adapted to hold both breath exhaled by the human subject and ambient air for inhalation by the human subject.

A fluid dynamic valve passively allows fluid flow out of a moving stream in one flow direction and not in the reverse. This allows the collection of fluid from a single direction of an AC fluid flow. The siphoned portion of the flow has a flow rate proportional to the mainstream flow. This device can collect exhaled breath or selective entrenchment during inhale. In one orientation, it can meter aerosolized particles into an inhale breath stream for pulmonary delivery, without complicated breath timing or drug loss due to drug adsorption to the back of the throat. Alternatively, a user can breathe through the device and a proportional amount, relative to the volumetric flow rate, of each exhale can flow into an auxiliary chamber for analysis. In addition, the device has a low respiratory burden and is comfortable to use.

Disclosed is a method for selectively capturing one or more portions of a patient's breath, comprising: detect one or more parameters regarding the patient's breath during a breathing routine; determine one or more data points from the detected one or more parameters wherein the one or more data points identifies one or more portions of the patient's breath to capture; and capture one or more portions of the patient's breath during the breathing routine.
