Abstract: Methods, apparatuses and systems are described for associating remote physiological monitoring with an at-risk falling condition of a patient. The methods may include receiving movement data of a patient from one or more sensors. The methods may also include determining a patient posture and a patient activity level based, at least in part, on the received movement data, and determining that an at-risk condition is satisfied by the patient posture or the patient activity level. Once it is determined that the at-risk condition is satisfied, the methods may also include issuing an alert based, at least in part, on the determination that the at-risk condition is satisfied.

Abstract: Methods, apparatuses and systems are described for determining respiration through impedance measurements using only two electrodes. A drive signal may be applied to a person, using only two electrodes. Using the same electrodes, the fluctuations in the voltage of the drive signal are determined. The voltage fluctuations in the drive signal are the result of impedance variations in the person's thoracic cavity due to respiration. Therefore, the voltage fluctuations may be used to determine a respiration rate of the person. In doing so, the voltage fluctuations may be digitized using a sampling rate that is much less than the frequency of the applied drive signal.

The methods may then include determining whether to reset the first turn timer based, at least in part, on whether the second amount of time meets or exceeds a predetermined perfusion time threshold. Once the patient has met or exceeded the predetermined perfusion time threshold, an alert may be issued.
