Adaptive data storage and download in a medical device
First Claim
1. A system for adaptively managing physiological data within a medical device, the system comprising:
- a medical device, the device comprising;
a physiological data monitor to monitor a physiological data parameter;
a memory circuit to store data collected by the physiological data monitor;
a processor circuit, coupled to the physiological data monitor and the memory circuit, the processor configured to,detect a pathological episode using the monitored physiological data parameter;
classify the pathological episode as one of a plurality of specified episode types;
capture, from the physiological data monitor, a segment of physiological data associated with the pathological episode;
select, in response to the classification of the pathological episode and using the classified episode type, a compression technique from a plurality of compression techniques to process the captured segment of physiological data;
process the captured physiological data using the selected compression technique to produce a processed segment of physiological data; and
store the processed segment of physiological data in the memory circuit for later use.

Abstract
In an example, a medical device includes a physiological data monitor (PDM), a memory, and a processor. The PDM is configured to monitor a physiological data parameter. The memory circuit is configured to store data collected by the PDM. The processor is configured to detect a data capture event and capture a first segment of physiological data associated with the data capture event. The processor is also configured to determine an amount of memory storage space available and determine a first priority level for the first segment of physiological data. The processor is further configured to determine a second priority level for a second segment of physiological data stored previously and select a processing scheme using the first and second priority levels. Finally, the processor is configured to process, using the processing scheme, the first and second segments of physiological data and store the first segment of physiological data.
