Abstract: Apparatus and methods are described including identifying that a subject suffers from sleep apnea. Positive airway pressure (PAP) is applied to the subject via a mask placed on a face of the subject. A respiratory-related parameter of the subject is sensed, while the mask is on the face of the subject, and a need of the subject for respiratory support is assessed, responsively to the respiratory-related parameter. In accordance with the assessed need, the mask is configured to regulate the PAP provided to the subject's face. Other applications are also described.

Abstract: Apparatus and methods are described for use of a sensor for monitoring a subject generate a sensor signal in response to the monitoring. Also disclosed is a computer processor to analyze the signal, and in response thereto, identify a correspondence between positions of the subject and occurrences of health events of the subject, and generate an output on the output device, in response to the identified correspondence. Other applications are also described.

Abstract: Apparatus and methods are described for monitoring a subject. A sensor monitors the subject and generates a sensor signal in response thereto and a plurality of filters are used to filter the sensor signal using respective filter parameters. A computer processor receives the sensor signal, filters the signal with each of two or more of the filters, and in response to a quality of each of the filtered signals, selects one of the plurality of filters to filter the sensor signal. Subsequently, the computer processor detects that the subject has undergone motion, by analyzing the sensor signal, and in response thereto, filters the signal with each of two or more of the filters, and in response to a quality of each of the filtered signals, selects one of the plurality of filters to filter the sensor signal. Other applications are also described.

Abstract: Apparatus and methods are described for use with a seat (82) of a vehicle, including a sensor unit (80) configured to be placed underneath the seat and configured to detect motion of a subject who is sitting on the seat during motion of the vehicle. The sensor unit includes a housing (90, 100), a first motion sensor (96, 106) disposed within the housing such as to generate a first sensor signal that is indicative of the motion of the vehicle, and a second motion sensor (98, 108) disposed within the housing, such as to generate a second sensor signal that is indicative of the motion of the subject and the motion of the vehicle. A computer processor at least partially distinguishes between motion of the subject and motion of the vehicle by analyzing the first and second sensor signals. Other applications are also described.

Abstract: Apparatus and methods are described for monitoring a subject. A sensor is configured to monitor the subject without contacting the subject or clothes the subject is wearing, and without viewing the subject or clothes the subject is wearing, and to generate a sensor signal in response to the monitoring. A computer processor is configured to: (a) receive the sensor signal, (b) extract from the sensor signal a plurality of heartbeats of the subject, and, for each of the extracted heartbeats, an indication of a quality of the extracted heartbeat, (c) select a subset of heartbeats, based upon the qualities of the extracted heartbeats, (d) for only the subset of heartbeats, determine interbeat intervals between adjacent heartbeats, (e) in response thereto, determine a physiological state of the subject, and (f) generate an output in response thereto. Other applications are also described.

Abstract: Apparatus and methods are described, including a method for detecting an onset of a hypoglycemia episode in a subject. One or more critical parameters for hypoglycemia are monitored without contacting the subject. A variation of at least one of the critical parameters is detected, and an alarm is activated when at least one of the critical parameters deviates from an accepted value. Other applications are also described.

Abstract: Apparatus is provided, including a sensor configured to sense motion of a subject and generate a motion signal in response thereto. The apparatus includes an output unit and a control unit. The control unit is configured to: (a) analyze the motion signal, (b) at a first time, determine that the motion signal is indicative that the subject is likely sleeping, (c) at a second time following the first time, determine that the motion signal is indicative that the subject is likely no longer sleeping, and (d) in response thereto, drive the output unit to alert a clinician if the subject is at an increased risk for falling out of a bed. Other applications are also described.

Abstract: Apparatus and methods are described including a motion sensor (30) that senses motion of a subject and generates a motion signal in response thereto. An oximetry sensor (86) measures oxygen saturation of the subject and generates an oximetry signal in response thereto. A control unit (14) analyzes the sensed motion and the sensed oximetry signal, and filters out false alerts relating to a condition of the subject generated by the oximetry signal, based on correlation between the oximetry signal and an aspect of the motion signal. Other embodiments are also described.

Abstract: Apparatus and methods are provided for use during endotracheal intubation of a subject, including an output unit, and at least one sensor configured to sense motion of the subject, and generate a signal responsively thereto. A control unit is configured to detect an aspect of the intubation by analyzing a component of the signal having a frequency of less than 20 Hz, and drive the output unit to generate an output indicative of the aspect of the intubation. Other applications are also described.
