3.2.1 EMMA Airway Adapter
The EMMA Airway Adapter is available in two models: Adult/Pediatric (Figure 3a) and Infant (Figure 3b).
EMMA operates to specification with either Airway Adapter model when used with its appropriate patient
population. A trained medical professional must determine the proper Airway Adapter model for each
patient application. No hardware or software configuration changes result from the EMMA Airway
Adapter model selected.
EMMA snaps in place on top of the EMMA Airway Adapter. The Airway Adapter may, for example, be
inserted between the endotracheal tube and the resuscitation bag or between the resuscitation bag and
the patient mask. Respiratory gas measurements are, as described in the previous section, obtained by
continuously measuring the infrared light absorption through the Airway Adapter. The EMMA Airway
Adapter is fitted with optical XTP™ windows that are transparent to light in the wavelength ranges of
interest.
