In a system and method for determining vital sign information of a subject the subject is illuminated with radiation, and radiation reflected from the subject is received. A region of interest is located in a first phase. Said illumination is controlled to locally illuminate, in a second phase, the located region of interest with radiation allowing determination of vital sign information. Finally, vital sign information of the subject is determined from the radiation reflected from said region of interest and detected in said second phase.

System and method for determining vital sign information

A patient monitor device includes one or more sensors which measure physiological parameters of a patient, a controller which controls an audio source to generate an audible tone and adjust the pitch or frequency of the audible tone to indicate the measured physiological parameter according to a mapping scheme, the audio source which generates the audible tone, and an audio output device which outputs the audible tone. The mapping scheme clamping a frequency of the audible tone after reaching a predetermined threshold.

Systems and methods for remote photoplethysmography and in particular for determining vital sign information of a subject are provided. The system includes a marker that is applied to a skin of the subject. The marker further includes a first marker area configured to transmit light at a first wavelength and a second marker area configured to transmit light at a second wavelength. The system further includes a detection unit that detects radiation received from the first marker area and from the second marker area of the marker. The system further includes an analysis unit that determines the vital sign information of the subject from the detected radiation from the first marker area and from the second marker area.

System and method for determining vital sign information of a subject

Vital sign information of a subject is determined using a marker for application to the subject. The marker is configured to change an optical property due to a mechanical manipulation of the marker caused by a physiological process of the subject. The change in the optical property is detected and analyzed to determine vital sign information of the subject.

A system and a related method extract physiological information from remotely detected electromagnetic radiation. The system includes an interface configured for receiving a data stream including image data representing an observed overall region of at least one subject of interest. A partitioning unit defines a plurality of sub regions in the overall region. A classifier classifies the plurality of sub regions into at least one indicative type of region and at least one auxiliary type of region. The at least one indicative type of region includes at least one indicative region of interest at least partially representing the subject of interest. The at least one auxiliary type of region includes at least one reference region. The system further comprises a data processor configured for processing at least one sub region classified as region of interest, thereby obtaining vital information.

A controlling device () is configured for controlling a state of an alarm limit of an alarm device (). The alarm device () is configured for generating an alarm signal in association with a monitored physiological parameter of a patient. The alarm limit triggers the generation of the alarm signal. In order to automatically control the state of the alarm limit, the controlling device () comprises a receiving unit () configured for receiving information indicating an administration of a treatment to the patient, a determining unit () configured for determining whether the treatment is administered to the patient based on the received information, and a controlling unit () configured for controlling the state of the alarm limit based on a result of the determination of the determining unit ().

A medical measuring device or system () includes at least one measuring apparatus (). Each measuring apparatus, in turn, has at least one sensor () for generating a measuring signal representing a sensed physiological parameter, e.g. ECG signals, of a patient (). The measuring apparatuses () incorporate the measuring signal into a carrier signal which is transmitted a wireless communication route () to a centrally located data detection device () which displays graphs () or numerical values () representing the sensed physiological parameters. The at least one measuring apparatus () signals the quality of the measuring signals to a wearing patient () via an LED () or loudspeaker ().

The invention concerns a system for monitoring and controlling a patient (), with a patient sensor () for capturing a patient signal, and a user interface () for providing a user with information on the captured patient signal, wherein the system comprises an integrated closed loop controller () which is fed with the patient signal and which controls a patient treating device () for treating the patient (). Thus, an easy and efficient way of monitoring and controlling a patient is provided.

The invention relates to a method for the presentation of information concerning variations of the arterial filling with blood (perfusion) of organs of living beings on the user surface () of a display screen, in which method the data required for the presentation (perfusion index) is derived, using an algorithm, from measuring values of a non-invasive photometric measuring process for determining the arterial oxygen saturation of the blood. The invention is characterized in that a first perfusion index is defined as a reference value and the subsequent perfusion indices are determined as relative deviations with respect to the reference value, said relative deviations being presented in the form of analog, graphic elements () on the user surface () as information concerning the 10 variations of the perfusion.
