CAUTIONS: • To avoid malfunction of the rotameters, keep the base unit upright at all times. • During NO therapy, always make sure: - to use two NO cylinders with a volume of at least 5 liters that are open throughout therapy - that the gas pressure of the active cylinder is above the limits specified in the pre-use check and that the inactive cylinder is full by regularly checking the pressure gauge on the cylinder regulator - to replace the NO cylinder directly after an NO cylinder 1 missing (or empty)/NO cylinder 2 missing (or empty) alarm is generated. • It is recommended always to perform a pre-use check before connecting the NO delivery and monitoring system to a patient. If the pre-use check is omitted, the system may not function correctly. • Always use autosense not constant rate when changing ventilator mode from conventional ventilation to High Frequency Oscillation (HFO) Ventilation and vice versa.
• To avoid malfunction of the rotameters and gas sensors, keep the base unit upright at all times. When the bedside/rail holder is attached to a post or rail, make sure the bedside/rail holder is firmly attached to the base unit and that the orientation of the clamp is such that the unit is upright. • The O2 cell and the NO and NO2 gas sensors are to be replaced once a year. • Gas sensor calibration needs to be performed once every three months. This can only be done in STANDBY by tapping SERVICE & SETTINGS/BIOMED/CALIBRATION. Refer to chapter Service & Settings on page 77. • Avoid kinks and small radius bends in the pneumatic tubing, i.e. flow sensor line, gas sampling and injection line for NO. Note that tubing with a small radius bend may work well at room temperature but may become blocked at elevated temperatures. • If drugs required for patient treatment are nebulized, contact the drug manufacturer to ensure that the drugs are compatible with NO delivery.
• In the USA, federal law restricts this device to sale by or on the order of a physician or other licensed medical practitioner.
• When lifting or moving parts of the NO delivery and monitoring system, follow ergonomic guidelines, ask for assistance, and take appropriate safety precautions.
• Do NOT use antistatic or electrically conductive tubing with this system.
• Always place two NO cylinders of the same size on the mobile cart to avoid the risk of overbalancing it. Refer to section Dimensions, weights and loads on page 101.
• Check the NO delivery and monitoring system for damage. If the system is damaged, it should not be used.
