E.3. Specifications
E.3.1. Intended use
The ISA OR+ product is intended to be connected to other medical backboard devices for
monitoring of breath rate and the following breathing gases:
ISA OR+: CO
2,
O

O ,Halothane, lsoflurane, Enflurane, Sevoflurane and Desflurane
ISA OR+ is intended to be connected to a patient breathing circuit for monitoring of inspired
/expired gases during anesthesia, recovery and respiratory care. The intended environment
is the operating suite, intensive care unit and patient room. ISA CO2 is also intended to be
used in road ambulances. The intended patient population is adult, pediatric and infant
patients.
Nomoline sampling cannulas are intended to be used as accessories to the ISA gas
analyzers. They are connected to the nostrils or to the nostrils and mouth on spontaneously
breathing
patients for sampling of CO

• Some models are also used to deliver O
2
in parallel
with CO
2 sampling. The intended patient population is adult, pediatric and infant patients.
