change in concentration occurs at the
sampling site
sampling
line config
A sampling line configuration consists of a
Nomoline Family sampling line connected to
either a patient breathing circuit or
spontaneous breathing patient

E.1.1. Warnings and Cautions
To avoid water condensation inside the ISA module and the connecting tubings,
ensure that the surrounding temperature of the ISA module and the connecting tubings
does not fall below the ambient temperature of the Nomoline sampling line.
E.1.2. 3886 Multi-Gas Unit
ISA OR+
The 3886 Multi-Gas Unit contains the Masimo ISA OR+ which is a low-flow sidestream
multigas analyzer designed to monitor respiratory
concentrations of CO

O and gas
mixtures containing any two of the five anesthetic agents
Halothane, Enflurane, lsoflurane ,
Sevoflurane and Desflurane in the OR and the ICU. Its low sampling flow and low agent
identification threshold makes the ISA AX+ a perfect choice for adult and pediatric
applications, as well as for the monitoring of infant patients with low tidal volumes and high
respiratory rates .
ISA OR+ sidestream analyzer offers the addition of oxygen
measurement capabilities by
means of an integrated paramagnetic O
2
sensor.
In the following information regarding the 3886 Multi-Gas Unit, the Masimo term “OR+” is
used interchangeably.
