WARNING:

Caution:

1. Avoid recirculation of gases. Undesired recirculation of gases will occur if fresh gas flows are less than the patient minute volume and may result in:

1. Note airflow direction on the Injector Module: the flow out of the absorber must pass through the Injector Module in the direction of the arrow on the module.

• Higher NO2 levels due to the limited ability of the carbon dioxide absorbent to remove NO2. • Higher concentrations than those set due to NO recirculated through the absorber. • Reduction in O2 concentrations because nitrogen is the balance gas for nitric oxide and will be present in the recirculated gases. 2. If the Injector Module was used in the wet/humidified part of the breathing circuit, it should be sterilized between each patient use.

2. Nitrous oxide (N2O) will affect the Set NO versus the measured NO value. For a 50% N2O, 50% O2 composition, the measured NO value will be approximately 7% indicated less than the same Set NO value of 100% O2. For example, at a Set NO of 20 ppm, measured NO will be approximately 18 ppm. 3. Similarly, the effect of 2% v/v isoflurane will result in a high measured NO value of approximately 3% indicated for the same Set NO value at 100% O2. 4. Sudden changes in anesthetic agent concentration may cause brief transient changes in the measured NO and NO2 values.
