Abstract: Systems and methods for managing patient monitoring devices are disclosed. Patient information is transmitted from a patient sensor operatively coupled to a patient to a patient monitor. The patient sensor and the patient monitor are communicatively coupled over a communications network available in a designated monitoring area. Further, loss of the patient sensor from the designated monitoring area is detected by one or more of the patient sensor, the patient monitor and a user. One or more loss prevention indicators are initiated at the patient sensor upon detecting the loss of the patient sensor. Additionally, the loss prevention indicators are communicated to indicate location of the lost patient sensor.

Abstract: The invention is focused toward enhancing a patient's mobility by providing seamless information/data transfer between medical monitoring devices such as a patient monitor, telemetry hubs, or another mobile monitoring system. The information or data, which are transferred among the medical devices include, but are not limited to, patient demographic information, wireless network, or pairing information. A set of wireless sensors (e.g. ECG, NIBP, Temp, SpO2), which are located on a patient's body, are connected wirelessly to a patient monitor, which is not a mobile device. When a clinician needs to move the patient from one location to a another location, the clinician brings the mobile monitor close to the fixed monitor to transfer the patient and wireless network information to the mobile monitor automatically. This enables the transfer of connected on-body wireless sensors from one medical device to another medical device without physically detaching them from a patient's body.

Abstract: A method for generating a sampled plethysmograph data, includes measuring a plethysmograph waveform indicative of a first cardiac cycle and a second cardiac cycle, each cycle including a systolic waveform and a diastolic waveform. The method further includes estimating a first start time and a first duration for the systolic waveform of the first cardiac cycle and computing a plurality of amplitudes at a plurality of time instants for the first duration. The method further includes determining a second start time and a second duration of the systolic waveform of the second cardiac cycle. The method also includes assigning the second cardiac cycle, the second start time, and the second duration to the first cardiac cycle, the first start time, and the first duration respectively. The method further includes iteratively performing the steps of measuring, estimating, computing, determining and assigning for the plurality of cardiac cycles acquired sequentially in time.

Abstract: In accordance with one aspect of the present technique, a method is disclosed. The method includes receiving continuous photoplethysmographic (PPG) data of a subject from a sensor and calculating a continuous blood characteristic (BC) based on the continuous PPG data. The method also includes calculating a first quality metric of the continuous PPG data based on a sequence of the continuous BC. The method further determines whether the first quality metric satisfies a stability criterion and sending a first notification to the sensor in response to determining that the first quality metric satisfies the stability criterion. The first notification instructs the sensor to collect compressed PPG data of the subject.
