`emergency mode, or any other appropriate mode, as
`described below.
`0035. The keeper mode may be used as the default mode of
`wearable device 105, such that wearable device 105 may
`enter this mode when the device is switched on. Other modes
`may alternatively be used as the default mode. In the keeper
`mode, wearable device 105 may, for example, continuously
`or intermittently, read the pulse and/or another parameters of
`a patient. In one example of keeper mode functioning, wear
`able device 105 may display parameter data on display area
`134, may alert the patient with a message on display area 134,
`and/or may alert the patient using an audible signal via
`speaker 136, for example, by playing back predefined audio
`signals. In addition, wearable device 105 may transmit the
`measured parameters to MC server 110 for analyses or pro
`cessing of the measured parameters, for example, using a FTP
`channel and/or a SMS channel. In the event where the staffin
`MC server 110 determines that the patient’s pulse is abnor
`mal, according to predetermined criteria or ranges described
`in detail below, wearable device 105 may alert the patient.
`0036. According to some embodiments of the present
`invention wearable device 105 itself may determine when one
`or more parameters are abnormal or, for example, in a danger
`range, instead of or in addition to the staff in MC server 110.
`According to some embodiments of the present invention MC
`server 110 may automatically determine when one or more
`parameters are abnormal or, for example, in a danger range,
`instead of or in addition to the staff in MC server 110. Addi
`tionally, wearable device 105 may senda warning message to
`MC server 110, using, for example, the SMS channel, FTP
`channel etc. When wearable device 105 is operated in keeper
`mode, parameters such as pulse, SpO, and ECG may be
`monitored continuously and/or at selected intervals, for
`example, every twelve hours.
`
`0037. In the extended mode, wearable device 105 may be
`set to perform operations according to a pre-defined schedule,
`for example, to periodically measure oxygen levels in the
`patient's blood (SpO) and/or ECG. In this mode, wearable
`device 105 may display parameter data on display area 134,
`may alert the patient with a message on display area 134,
`and/or may alert the patient using an audible signal via
`speaker 136, for example, by playing back predefined audio
`signals. In addition, wearable device 105 may transmit the
`measured parameters and/or results from analyses or process
`ing of the measured parameters, to MC server 110, for
`example, using FTP channel and/or SMS channel. When
`wearable device 105 is operated in extended mode, vital signs
`such as pulse, SpO2, and ECG, may be monitored, for
`example, five times a day by default (e.g., the default may be
`at shorter or longer intervals, as required). If the staff at MC
`server 110 or the MC server 110 detect, for example, that the
`heart rate, oxygen level in the blood, and/or ECG records
`and/or other data are abnormal (e.g., according to pre-defined
`criteria or ranges as discussed below), wearable device 105
`may alert the patient by providing output signals in the dis
`play area 134 or via speaker 136. Additionally or alterna
`tively, wearable device 105 may send a message to MC server
`110, or to another destination, for example, using the FTP
`channel.
`0038. In emergency mode a patient may initiate operation
`of the medical monitoring system 100 by pressing, for
`example, any of the emergency buttons 116 or 118. When
`operating in emergency mode, wearable device 105 may send
`emergency messages to MC server 110 or to another destina
`tion using, for example, the FTP channel. Emergency mes
`sages may additionally or alternatively be sent to MC server
`110 or to another destination via the SMS channel, for
`example, in cases where the FTP channel is not available. In
`addition, when entering an emergency mode, measurement of
`SpO2 level, ECG level, and/or additional suitable parameters
`may be initiated. The staff of MC server 110 or the MC server
`110 itself may initiate a call to the patient of wearable device
`105, or may send a message etc.
`0039. According to some embodiments of the present
`invention, Software or device program updates (referred to
`herein as “software updates') may be implemented to enable
`individualized adaptation of operation parameters of device
`105. Customizable software updates may include, for
`example, customizing one or more modes of operation for
`each patient, customizing ranges or thresholds for monitoring
`of an individual patient's parameters, customizing timing of
`parameter measurements, customizing alert functions, deter
`mination of types of measurements to be monitored, custom
`izing diagnostic ranges, adding new features or Software
`improvements, deleting features that are not relevant for a
`particular patient's condition monitoring, customizing opera
`tional modes, correcting Software problems, and/or any other
`suitable modifications. The customized or individualized pro
`grams may be programmed directly into wearable device 105
`using wire based or wireless data communication, and/or may
`be remotely transferred to wearable device 105. In this way
`the timing parameters or other aspects of operation of wear
`able device 105 may be modified and updated, optionally
`remotely, by MC server 110, at the discretion of the MC staff
`or automatically using pre-defined criteria. For example, the
`MC may remotely initiate a certain mode of operation for
`wearable device 105, and/or may remotely change vital
`parameter ranges, etc., optionally for each patient individu

`grammed directly into a single wearable device 105 or into a
`group of wearable devices 105.
`0040. According to some embodiments of the present
`invention, measurements of SpO and/or pulse may be
`executed using reflected light. For example, light may be
`emitted by a light emitting component, e.g., a light emitting
`diode (LED) onto a suitable part of a patient's body, and the
`light reflected from the body may be detected by a light
`detecting component on wearable device 105. The patient's
`SpO, pulse, blood pressure, SpA. and/or other physiologi
`cal parameters and/or environmental parameters may be cal
`culated from the detected light. The light to be reflected may
`be emitted in one or more wavelength ranges, as is known in
`the art. In order to simplify and to clarify, the sub-system or
`Sub-systems for measuring the SpO may be described and
`illustrated herein as being composed, for example, of an
`emitting/receiving unit and an electronic unit. In the same
`manner the Sub-system or Sub-systems for measuring pulse
`may be described and illustrated herein as being composed,
`for example, of an emittin
