12.2.3 MicroPod
®
sensor module
The module is designed to be incorporated into a host monitoring system. The module allows for
measurement of inspired /expired carbon dioxide and respiration rate on patients in the Operating
Room, ICU, NICU, Sedation procedures, GI, General Floor, Transport and Emergency treatment.
The method for measuring etCO
2
is based on non-dispersive IR absorption of the etCO
2
in the
breath sample using the Oridion IR source.
The major components of the module are as follows:
• etCO
2
sensor assembly, including the Oridion long-life source
• Flow System, including pump
• FRS to identify the correct usage of a Microstream® FilterLine
• Input gas connector with the FRS interface
• Power supply
• Serial interface
• μController + peripherals
The capnography module is intended to provide professionally trained health care providers with
continuous, non-invasive measurement and monitoring of carbon dioxide concentration of the
expired and inspired breath and respiration rate. The capnography module is intended for use with
neonatal, pediatric, and adult patients in hospitals, hospital-type facilities, transport, intra-hospital
transport and home environments.
The MicroPod contains the Oridion microMediCO
2
module and uses Microstream capnography. The
MicroPod external CO
2
module attaches to the host monitor with an external communication cable,
and data from the module appears on the host monitor screen.
Microstream capnography modules use Microstream non–dispersive infrared (NDIR) spectroscopy to
continuously measure the concentration of CO
2
during every breath, the concentration of CO
2
present at the end of exhalation (EtCO
2
) and the respiratory rate. The respiration rate is referred on
the fabian HFO as Freq etCO
2
. Infrared spectroscopy is used to measure the concentration of
molecules that absorb infrared light. Because the absorption is proportional to the concentration of
the absorbing molecule, the concentration can be determined by comparing its absorption to that of a
known standard.
