FEATURES
Overview
OVERVIEW
The NELLCOR N-200 pulse oximeter measures functional
oxygen saturation of arterial hemoglobin (SpO2), and pulse
rate. The system consists of three components: the N-200 pulse
oximeter, an interface/powerbase, and a patient module. The
N-200 monitors SpO2 and pulse rate continuously and
noninvasively, with measurements updated at each pulse beat.
The interface/powerbase is a detachable AC power supply and
external interface for the N-200. It provides isolated power for
operating the monitor and charging its internal batteries. In
addition, the interface/powerbase provides analog and digital
outputs for external data recording devices and an input for
C-LOCK ECG synchronization. A fiber optic output can be used
to connect the N-200 to a NELLCOR N-7500 pulse oximetry
network. The patient module (models C-13-200, C-20-200, or
C-13-200M) provides a connector for the oximetry sensor and
provides initial oximetry signal processing; models C-13-200
and C-20-200 also provide an ECG input connector.
Automatic Self-Test and Startup
The N-200 provides immediate use after startup, without need
for operator calibration or configuration. It offers:
• Automatic self-test and error messages
• Automatic oximetry calibration
• Visible oximetry display
• An early warning system that provides an audible
indicator for both SpO2 and pulse rate: a tone sounds on
each pulse, and its pitch varies with changes in SpO2
• Operator-configured visible and audible oximetry alarms,
with default alarm limits preset for adults or neonates
