For individuals dealing with respiratory conditions, maintaining consistent and comfortable breathing support is crucial. The Airvo 2 from Fisher & Paykel is a high-flow nasal cannula (HFNC) therapy device designed to deliver warm, humidified air and oxygen to patients in need of respiratory support. Whether you're using it at home or in a clinical setting, understanding how to properly operate and maintain your Airvo 2 is key to ensuring the best outcomes for your respiratory health. This guide will walk you through everything you need to know about using your Airvo 2 safely and effectively.
The Airvo 2 is a non-invasive respiratory support device intended for patients with a range of breathing difficulties, including chronic obstructive pulmonary disease (COPD), bronchiectasis, and sleep-related breathing disorders. Unlike standard oxygen therapy, the Airvo 2 delivers air (with or without supplemental oxygen) at high flow rates, typically between 10 and 60 liters per minute. This helps keep airways open, promotes better gas exchange, and reduces the work of breathing.
The unit consists of the main Airvo 2 machine, a heated breathing tube, a humidification chamber (water chamber), and a nasal cannula or tracheostomy interface. It also requires sterile or distilled water for proper humidification.
Before you begin, place the Airvo 2 device on a stable surface near your bed or chair. Make sure the device is plugged into a grounded electrical outlet. Insert the humidification chamber into the designated slot on the front of the machine. Fill the chamber with sterile or distilled water to the indicated level. Do not use tap water, as it can lead to mineral buildup and reduce the device’s effectiveness.
Next, connect the heated breathing tube to the humidification chamber and attach the nasal cannula to the other end. Ensure all connections are secure. If your device is prescribed with supplemental oxygen, connect the oxygen tubing to the oxygen inlet port on the back of the machine. Your healthcare provider should provide specific instructions on how much oxygen to add.
Turn on the Airvo 2 using the power button. Once it boots up, you’ll see a digital display where you can adjust the flow rate and temperature. Your healthcare provider will prescribe a specific flow rate and temperature setting, so it’s important not to change these settings unless directed. Use the control knob to navigate through the menu and set the prescribed values.
It usually takes a few minutes for the machine to heat the water and reach the desired temperature and humidity levels. During this time, you may notice some condensation in the tube, which is normal. The humidified air ensures greater comfort and reduces airway irritation.
Using the Device
Once the device is ready, position the nasal cannula properly. The prongs should sit gently in your nostrils, and the tubing should be secured around your ears or head using the included strap or clip. Breathe normally through your nose while the device is in operation. The warm, moist air can feel unusual at first, but most users find it very comfortable once they get used to it.
If your device is running overnight, ensure that the tubing is not kinked or twisted, and that the cannula stays in place during sleep. You may need to adjust the straps to achieve a secure but comfortable fit.
Daily cleaning and regular maintenance are essential to keep your Airvo 2 functioning properly. After each use, disconnect the nasal cannula and discard it if it’s disposable or wash it if it’s reusable, following the manufacturer’s instructions. Empty any remaining water from the chamber, rinse it thoroughly, and let it air dry. Avoid using harsh chemicals or cleaning agents.
Once a week, inspect the breathing tube and replace it if there are signs of wear or condensation buildup that won’t clear. The water chamber should be replaced as recommended—typically every 30 days or according to your supplier’s guidelines.
Troubleshooting Common Issues
If you experience low airflow, check all tubing connections and ensure the humidification chamber is properly seated. A “low water” warning means you need to refill the chamber with sterile water. If the device overheats or shows an error code, turn it off, unplug it, and contact your provider or the manufacturer for assistance.
Avoid using the device near open flames, direct sunlight, or while smoking. Always follow the safety instructions provided in your user manual.
