This manual describes the use and operation of the Model 2001 Pulse Oximeter Monitor from Novametrix Medical Systems Inc. Model 2001 is a lightweight, easy to use, pulse oximeter designed to be used in a variety of clinical settings. It provides reliable measurement, display and alerts for functional pulsatile oxygen saturation (SpO2) and pulse rate. The monitor can be powered from the AC Mains (line voltage) or from its rechargeable internal battery. Numerical and waveform information is presented on a bright Cold Cathode Display (CCD) with user adjustable contrast to optimize viewing angles. A simple menu system allows user selection of measurement and display options. Alerts are menu programmable or automatic. Numerical and plethysmogram displays are continually updated. Presence of a pulse is indicated audibly by a user selectable “beep”. Separate 24 hour trends for SpO2 and pulse rate are updated every 8 seconds. In addition, trend “events” and audible alarm status (Audio Off) are stored in trend memory. The monitor is equipped with an RS232 serial output port for easy interfacing to external equipment. An optional Analog Output module provides analog outputs. Per requirements of IEC 601-1, the Model 2001 is classified as class II equipment, with type BF applied part, and an enclosure protection rating of IPX0. The Model 2001 is Year 2000 compliant.
