1.3 PRODUCT DESCRIPTION
The handheld capnograph/pulse oximeter is used to continuously monitor
end-tidal carbon dioxide (EtCO2), respiratory rate, oxygen saturation
(SpO2), and pulse rate. The monitor is for attended monitoring only and
must be used in the continuous presence of a qualified healthcare
provider.Themonitorcan be used on adult, pediatric,andinfant/neonatal
patients. It is intended for use where continuous, noninvasive monitoring
of these parameters is desired, including hospital and mobile use (when
