1.1 About the Atlas Monitor
The Atlas combines in one unit all the necessary mea-
surements for patients under anesthesia, for surgical
recovery, or bed side monitoring. See Section 1.3 for a
complete listing of product models and options.
According to the standards of care for Nurse Anesthe-
tists and Anesthesiologists, all patients receiving con-
scious sedation are to be continuously monitored
throughout theprocedure and recovery phase by ECG,
SpO2, and NIBP. CO2 monitoring is a requirement dur-
ing gas anesthesia (when patient is ventilated).
The Atlas combines a CRT to display ECG and CO2
waveforms and LEDs for the other numeric values to
maximize visibility and viewing angle. Although not
designed to be a transport product, the monitor has an
integral handle and it is small and light enough at 13 lb
to be easily moved. A one hour battery enables the
monitor to be moved with the patient from the surgery
room to recovery room. It also maintains unit operation
for up to an hour when power is interrupted.
IMPORTANT: for a complete description on the func-
tion and use of the Atlas, as well as user safety warn-
ings, cautions, and warranty information, read and
understand the Atlas Operator’s Manual part number
6200-42E (English). Other languages are available.
