A disposable humidification chamber is integral, holding the sterile water required for humidification and featuring a unique water level sensor.
The heated wire breathing circuit is another crucial element, maintaining consistent gas temperature and preventing condensation throughout the delivery pathway. This circuit connects to the Airvo 2 unit and the patient interface. A power supply provides the necessary electrical energy for operation, while an oxygen input connection facilitates integration with an oxygen source.
Additionally, the system includes filters to ensure air purity and prevent contamination. Manuals available on platforms like manualmachine.com and studylib.net detail the specific types of filters used. Finally, the user interface, consisting of a display screen and control buttons, allows for easy adjustment of settings and monitoring of system performance. Each component plays a vital role in the Airvo 2’s overall functionality.
Setting Up the Airvo 2
Initial setup of the Airvo 2 requires a clean, stable surface near the patient and an accessible power outlet. Begin by carefully unpacking all components and verifying their integrity. Attach the humidification chamber securely to the base unit, ensuring a proper seal to prevent leaks. Connect the heated wire breathing circuit to both the Airvo 2 and the designated patient interface, confirming a firm and secure connection at both ends.
Before powering on, inspect all connections for any signs of damage or dislodgement. Ensure the water level sensor within the chamber is functioning correctly. Refer to the technical manual available on archive.org for detailed diagrams. Position the Airvo 2 unit to allow for unobstructed airflow around the vents, preventing overheating.
Double-check that the oxygen source is readily available and compatible with the Airvo 2’s input requirements. Finally, familiarize yourself with the location of the power switch and emergency shut-off procedures, as outlined in resources like studylib.net. A properly set-up Airvo 2 is crucial for safe and effective operation.
Connecting to Oxygen Source
Establishing a secure oxygen connection is paramount for effective Airvo 2 operation. The device is designed to integrate with a central oxygen supply or an oxygen concentrator, adhering to relevant medical gas standards. Utilize only oxygen-compatible tubing, ensuring it’s free from cracks or kinks. Connect the oxygen supply tubing to the designated oxygen inlet on the Airvo 2’s rear panel, tightening the connection firmly to prevent leaks.
Prior to activation, always verify the oxygen supply pressure falls within the Airvo 2’s specified operating range – consult the technical manual on archive.org for precise specifications. A pressure gauge should be incorporated into the oxygen line to monitor flow accurately. Slowly open the oxygen supply valve, observing the Airvo 2’s display for confirmation of oxygen delivery.
Regularly inspect the connection point for any signs of leakage using an appropriate leak detection solution. Never force connections. If difficulties arise, immediately disconnect the oxygen supply and consult the troubleshooting section of the user manual found on manualmachine.com. Proper oxygen connection ensures consistent and reliable therapy.
Humidification Chamber Assembly
Correct assembly of the humidification chamber is crucial for delivering optimally humidified gas to the patient. Begin by carefully removing the chamber from the Airvo 2 unit. Disconnect the water container, ensuring no water remains in the chamber’s airway. Inspect the chamber and lid for any visible damage, cracks, or debris – replace if necessary.
Align the water container with the chamber, ensuring a secure fit. Fill the container with the appropriate type of water (distilled or demineralized – see ‘Water Level and Type Requirements’). Reattach the lid, confirming it clicks firmly into place, creating a watertight seal. Improper sealing can lead to leaks and ineffective humidification.
Before re-installing the chamber onto the Airvo 2, visually inspect the chamber assembly for completeness and proper alignment. Gently slide the assembled chamber onto the unit’s mounting rails until it locks securely. Refer to the diagrams in the technical manual available on studylib.net for visual guidance. A correctly assembled chamber is fundamental for effective humidification and patient comfort.
Water Level and Type Requirements
Maintaining the correct water level and using the appropriate water type are paramount for optimal Airvo 2 performance and preventing potential issues. The humidification chamber requires filling to the ‘Max Fill’ line indicated on the water container. Do not overfill, as this can cause leakage and compromise the system’s functionality.
Crucially, only distilled or demineralized water must be used in the Airvo 2. Tap water, bottled water, or any other water source contains minerals and impurities that can lead to bacterial growth, biofilm formation, and damage to the humidifier. These contaminants can also be aerosolized and delivered to the patient, posing a health risk.
Regularly check the water level during operation, especially with higher flow rates, as evaporation will occur. Empty, clean, and refill the chamber daily, or more frequently if needed. Discard any remaining water at the end of each patient use. Refer to the Airvo 2 technical manual (available on archive.org and manualmachine.com) for detailed guidance on water quality and maintenance procedures.
Powering On and Initial Checks
Before initiating Airvo 2 operation, a series of checks are essential to ensure patient safety and device functionality.
