Abstract
The present invention provides an apparatus for continuously recording physiological data. The invention includes a unique data mapping and compression technique which allows relatively long term data acquisition without compromising the data sampling rate. The present physiological data recorder has application in recording physiological data which is non-periodic and is characterized by 'bursts' of rapid activity interspersed among relatively long periods during which there is little or no activity. The invention has specific application in recording pH data in ambulatory patients and comprises a unique data compression means, an automatic calibration means, and a digital or analogue data playback means.
