Physiological sensor history backfill system and method
First Claim
1. A method of sensor history backfill for a local base device operable to wirelessly communicate with a physiological sensor connected to a patient, the method comprising:
- obtaining physiological readings for the patient at a predetermined interval;
storing the physiological readings at the physiological sensor as sensor physiological readings;
transmitting the physiological readings from the physiological sensor to the local base device;
storing the physiological readings at the local base device as historic physiological readings;
obtaining a current physiological reading for the patient;
transmitting the current physiological reading from the physiological sensor to the local base device in a current reading message;
detecting at the local base device a record gap in the historic physiological readings between the current physiological reading and the historic physiological readings;
identifying missing physiological readings in the record gap;
transmitting a request for the missing physiological readings from the local base device to the physiological sensor when the current reading message does not include the sensor physiological readings to fill the record gap;
selecting sensor physiological readings for the missing physiological readings;
transmitting the selected sensor physiological readings from the physiological sensor to the local base device; and
filling the record gap in the historic physiological readings with the selected sensor physiological readings from the physiological sensor.

11. A method of sensor history backfill for a local base device operable to wirelessly communicate with a physiological sensor connected to a patient, the method comprising:
-
obtaining physiological readings for the patient at a predetermined interval, each of the physiological readings being associated with a physiological reading time; storing a predetermined storage number of the physiological readings at the physiological sensor with the associated physiological reading time, the predetermined storage number being greater than or equal to one and greater than a predetermined packet number; measuring a current physiological reading for the patient at a current measurement time; transmitting from the physiological sensor to the local base device a current message including the current physiological reading, the current measurement time, and the predetermined packet number of the physiological readings immediately before the current physiological reading, the predetermined packet number being greater than or equal to zero; retrieving a last stored physiological reading time from the local base device memory; calculating a time gap between the current measurement time and the last stored physiological reading time; setting a backfill start time equal to the last stored physiological reading time when the time gap is greater than a packet duration defined as the predetermined interval multiplied by the predetermined packet number; requesting the physiological sensor to transmit to the local base device the predetermined packet number of the physiological readings immediately after the backfill start time; storing the predetermined packet number of the physiological readings immediately after the backfill start time in the local base device; adding the packet duration to the backfill start time; and repeating the requesting, the storing, and the adding when a backfill end time defined as the backfill start time less the packet duration is less than the current measurement time. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
