WARNING
EtCO2 values may differ from blood gas readings.
WARNING
A failure in zeroing airway gases may cause inaccurate readings
WARNING
Always ensure the correct size and fit of accessories according to patient type and application, especially when monitoring pediatric and neonatal patients. The size and fit of accessories may impact the measured gas concentration values at low tidal volumes. It is recommended to have the gas sampling port close to the proximal end of the endotracheal tube. Excessive dead space in the circuit, including the accessories, may cause re-breathing of gases. Very low accessory dead space between the breathing circuit Y-piece and the gas sampling site may impact the measured gas concentration due to dilution of the sampled exhaled gas with fresh gas from the ventilator. To confirm accurate correlation with measured gases and blood, check arterial blood gas values to confirm a suitable setup is used.

About single-use sidestream on-airway adapters CAUTION
The Adult/Pediatric and the Infant/Neonatal on-airway adapters are intended for single use. Do not reuse or sterilize the adapters as system performance will be compromised.
CAUTION
Always insert the sample cell of the LoFlo sampling line into the sample cell receptable on the LoFlo Sidestream Module before inserting the on-airway adapter into the ventilator circuit. Failure to follow this may introduce a leak in the circuit, thereby reducing set minute volume.
CAUTION
Remove the LoFlo airway adapter and sampling line sample cell from the receptacle when not in use.
NOTE
Do not place the on-airway adapter between the ET tube and the elbow as this may allow patient secretions to accumulate in the adapter. If pooling does occur, the on-airway adapter may be removed from the circuit, rinsed with water (or sterile water) and reinserted into the circuit. If rinsed, make sure that no water has entered the sampling tubing. If so, blow out water or replace the adapter. To prevent moisture from draining into the on-airway adapter tubing, always place the on-airway adapter tubing in an up position:
The Adult/Pediatric sidestream on-airway adapters should be used when monitoring intubated patients with Endotracheal Tube diameters greater than 4.0 mm. Use the Infant/Neonatal on-airway adapters when monitoring intubated patients with Endotracheal Tube diameters less than or equal to 4.0mm.
