Introduction Intended Use
The Hudson RCI® Aquatherm® III Plus External Adjustable Electronic Heater is designed for use with the Hudson RCI Nebulizer Adaptor and the Aquapak® system to provide continuous heated aerosol for respiratory applications.
Heater Operation
The Hudson RCI Aquatherm III Plus Heater is placed between a nebulizer adaptor and a reservoir of sterile solution. When gas flow is initiated to the nebulizer, sterile solution is drawn up from the reservoir and through the stainless steel puncture pin in the center of the Aquatherm III Plus Heater. The solution is heated as it flows through the pin. The heated solution is then drawn into the nebulizer adaptor where it is aerosolized into the patient gas stream. Rainout within the nebulizer adaptor returns to the reservoir bottle via a rainout return tube. The warmed rainout gradually raises the temperature of the reservoir contents, increasing the overall heat output of the device. An electronic temperature control circuit provides consistent heating across a wide range of adjustments. A non-reversing thermal fuse prevents overheating in the event the control circuit fails.

Directions for Use Installing the Heater
Performance of this procedure requires a compressed gas source, a clean, unused nebulizer adaptor and a Hudson RCI Aquapak, reservoir bottle. The Aquatherm is to be installed and monitored by trained medical professionals. Thoroughly clean and test the heater before installing and placing it in service. When this assembly is complete, the reservoir bottle is suspended from the bottom of the heater and does not rest on a surface. Temperature is measured at the output end of the sixty inch hose, closest to the patient. To connect the Aquatherm to main power, plug the device in. To cut power to the Aquatherm, unplug the device. Ensure that the device is positioned in such a way that disconnection from main power is not impeded. Caution: Always ensure the heater is aligned in a vertical position for best performance. 1. Check the heater to be sure all surfaces are clean and intact. Wipe the heater with a damp cloth and mild detergent if necessary. 2. Turn the power switch to OFF. 3. Turn the temperature control knob to the number “1,” fully to the left. 4. Attach a clean, unused nebulizer adaptor to the threaded nebulizer connection on top of the heater. 5. Connect the Hudson RCI Aquapak reservoir to the threaded reservoir connection at the bottom of the Aquatherm III Plus Heater. Insert the flange on top of the bottle into the fitting underneath the heater. Turn the bottle to the right until it is secured to the bottom of the heater and stops. Do not overtighten. 6. Remove the plastic cap from the end of the nebulizer rainout return tube, to expose the connector pin. 7. Insert the pin into the round, ¼ inch diameter raised surface above the label. Use a slight twisting motion to pierce the plastic bottle and seat the pin. A brief “whoosh” sound may be heard as the pin pierces the bottle. 8. Screw the threaded wing nut on top of the nebulizer adaptor onto the flow meter bottom flange on the oxygen source. Rotate the nut in a counterclockwise direction (as viewed from above) to attach it to the nebulizer adaptor. Ensure the nut is hand tight, do not overtighten. 9. Inspect all connections and ensure they are secure. 13
Placing the Heater in Service Warning: Always measure and verify aerosol temperature before connecting the heater to the patient. Warning: Always measure and verify oxygen concentration before connecting the heater to the patient. Warning: Gas temperature, room temperature, flow rate, entrainment collar setting, and aerosol delivery tube length all affect the output temperature, and depending on conditions may result in aerosol delivery exceeding 41 °C (105°F) at the patient. Warning: Do not operate the heater without oxygen or air flow to the nebulizer adaptor. 1. Connect the nebulizer to an oxygen or air source. 2. Plug the power cord into a grounded electrical outlet. Ensure there is power at the outlet and that the outlet meets the voltage requirements stated in this manual. 3. If using oxygen, adjust the nebulizer entrainment collar and select the desired oxygen concentration. If using an air source, adjust the nebulizer entrainment collar to achieve the desired total flow. 4. Adjust the oxygen or air flow to the recommended flow rate. For use with compressors, adjust the outlet pressure to a level that achieves the desired total flow. 5. Connect aerosol tubing to the nebulizer outlet. Tubing specifications are not less than 152 cm in length and 22 mm in diameter of standard aerosol delivery tubing. 6. Connect open end of aerosol tubing to a thermometer or other device for monitoring aerosol temperature (i.e., Hudson RCI 1647 not included). 7. Connect to patient interface, such as a face mask, tracheostomy mask, or trach tee. 8. Turn the heater power switch ON. 9. Turn the temperature control knob to the right, to the desired setting. For all flow entrainment settings, it is recommended to set the heater temperature at the number 5 to start. 10. Allow 25 minutes for the outlet temperature to stabilize. 11. Adjust the temperature in small increments and allow about 20 minutes after each adjustment for the temperature to change and stabilize.
