10.1 System Overview
The N5500 patient monitor is a multi-function monitor for use on adult , pediatric and
neonatal patients; ECG, heart rate, non invasive blood pressures, arterial oxygen
saturation, pulse rate, respiration rate and temperature.
In addition to monitoring and displaying the status of these physiological parameters, the
instrument performs various microprocessor-programmed analytical functions;
l
Creating both visual and audible alarm signals when settable limits are violated;
l
Creating and displaying warning/error messages when conditions are detected that
would degrade or prevent valid measurements;
l
Creating and displaying graphical or tabular trend data;
l
Providing input to an optional recorder for printout of current or tabular trend data.
The monitor is essentially a battery-powered instrument. An internal charging unit is
designed to accept only an AC line voltage.
