6.1 Introduction
The intent of this procedure is to ensure that the product continues to be safe and effective
in its intended environment. Complete knowledge of the instrument characteristics and its
relationship to the clinical environment are useful in determining changes in the
performance of the monitor, and the clinical limitations of the device.
As a general rule, the instrument is not tested to the full limits of it's capabilities at each
service interval. Rather, representative points are tested and the results recorded. It is
important to note that while not all functions are tested to the absolute limits, every
function and option should be exercised. Declining performance over time is frequently
the first indication of the need for more extensive service action.
6.2 Limitations Of Physiological Simulators
The physiological simulator is the principle aid for problem solving. Simulators have
many of the same limitations as the devices that they will test. It is imperative that the
simulator correlate well to a "Reference Standard*". The electronic simulators available
attempt to replicate a broad spectrum of indices representative of normal and abnormal
physiological events, within the interpretation of the manufacturer.
