The disclosure is directed to an apparatus and a method for improving manual ventilation and resuscitation by monitoring ventilation parameters and assisting resuscitation. The apparatus includes a gas flow sensor configured to measure a flow rate of exhaled gas of a subject. The apparatus is configured to receive an ideal body weight or a predicated body weight of the subject and calculate a first tidal volume range based on the ideal body weight or the predicated body weight of the subject. The apparatus is also configured to obtain an exhaled tidal volume of the subject based on the measured flow rate and determine whether the exhaled tidal volume is within the first tidal volume range. When it is determined that the exhaled tidal volume is not within the first tidal volume range, the apparatus is further configured to perform a first tidal volume warning.

A method and device allowing a physiological signal, typically representative of brain activity, to be transcribed in the form of sensory signals perceptible to a human user, typically acoustic signals is provided. For this purpose, a physiological signal is acquired and then analysed in such a way as to detect therein patterns that are then parameterised in the time domain. One or more parameters of these patterns are used to determine one or more parameters of the generated sensory signals and/or to determine one or more parameters of temporal envelopes used to modulate the sensory signals. This method and device can be applied, in particular, to neuro-acoustic transduction.

A magnetometer-based metal detection device and methods of use are described. The device includes a proximal portion, a central body and a distal portion, and at least one magnetometer positioned within or on the distal portion. The at least one magnetometer includes at least one sensor capable of sensing a magnetic field in three orthogonal axes. Also described is a method of calibrating the device to achieve rotational invariance, and a method of determining a directionality or directional line along which a target metal object lies.

Provided are concepts for generating an indicator of chronic obstructive pulmonary disease (COPD) in a subject. In particular, an elasticated bag suitable for inflation is utilised, such that a change in a measurable characteristic of the elasticated during exhalation of the subject is detected. The change in the measurable characteristic may be analyzed so as to generate an indicator of COPD. Thus, this indicator may be used by a skilled professional in deciding whether to further investigate the possible presence of COPD.

To be capable of efficiently transmitting appropriate information on the motion improvement to a person in motion. A motion evaluation system includes a sensor unit, an information processing device, and an information presentation device. The information processing device includes a communication device, a storage device, and an arithmetic device. The arithmetic device acquires motion data acquired by observing a user through the use of a sensor via the communication device, checks the motion data against information about the correctness of motions in the reference information, determines a state of motion of the user, specifies a motion in a state to be improved as an improvement, check the motion data after the motion corresponding to the improvement against information about busy levels of the user to specify a busy level of the user, and outputs, as improvement suggestion information about the improvement, information with different contents at each of multiple times to an information presentation device based on the improvement and a rule predetermined according to each situation of the busy level.

A method for assisting a user in selecting audible alarm settings of a patient monitoring system for monitoring a patient is provided. A synthesis model is generated in response to 1) data indicative of audio features derived from audio recorded in the patient room, and 2) data indicative of vital signs recorded from the patient monitoring system. Sets of audio parameters indicative of respective plurality of audible alarm settings are then processed according to the synthesis model so as to generate respective outputs, e.g. indicative of audibility of the plurality of alarm sounds according to the audible alarm settings synthesized to be played in or outside the patient room. These outputs can then be presented to a user, so as to allow the user to evaluate e.g. alarm audibility and noise level impact of the plurality of audible alarm settings, and e.g. adjust the settings accordingly, such as alarm thresholds etc. The synthesis model may comprise an auralization module, so as to generate synthesized audio outputs to the user. The synthesis model may take into account actual room acoustics in or outside the patient room, so as to allow a precise calculation and/or audio synthesis of an alarm sound to be played in the environment. Alternatively, or additionally, the systhesis model can generate objective and/or subjective metrics that allows the user to find a suitable balance between alarm audibility and impact on noise level.

A non-invasive sensor unit, such as a glove or pad, is adapted to be placed over the chest of an injured person who may be in need of CPR and/or AED. The sensor unit includes a plurality of electrodes for detecting one or more ECG voltages of the person. A controller processes the ECG voltages and displays them on a display, thereby enabling the user to assess whether CPR and/or AED is needed. The sensor unit is adapted to continue to provide ECG data while the user is applying chest compressions to the person. The sensor unit may include accelerometers for reducing artifacts from the ECG voltages that arise from the movement of the user while applying chest compressions. The electrodes are, in some embodiments, capacitive sensors that enable ECG voltages to be detected without requiring direct contact with the skin of the person.

Methods providing biofeedback generally comprising: detecting a brainwave segment present in the brainwaves; reproduction of the segment at a higher octave and rendering said higher frequency as a feedback signal to the person. The feedback signal can be rendered at a higher frequency by any number of octaves, and/or musical harmonies thereof. Feedback frequency and amplitude correspond to shifting frequency and amplitude in the underlying brain/heart activity. Feedback signal is preferably rendered within 100 msec from brainwave detection, and can be administered as treatment using any bandwidth within the electromagnetic spectrum including sub-audio, audio, ultrasonic, light, etc. The feedback signal can be delivered to the same or opposite side of the person relative to the hemisphere generating the signal. Said feedback signal can help balance brainwave activity, forge new neuro-circuits, increase interhemispheric communication, creativity and brain-efficiency thereby improving a full spectrum of nervous system activity from hyperarousal to deep sleep.
