High Flow Nasal Cannula Machine: Common Issues and Solutions

High flow nasal cannula (HFNC) machines are devices used to provide a continuous flow of oxygen to patients with breathing difficulties. Often used for patients with chronic obstructive pulmonary disease (COPD) or other respiratory conditions, HFNC machines can be a life-saving tool for those who require oxygen therapy. While these machines are typically reliable, there are some common issues that can arise when using them. Here we discuss the most common issues and solutions for troubleshooting these machines. 

Issues with flow rate

One of the most common issues with high flow nasal cannula machines is incorrect flow rate. This can occur when the machine is set to an incorrect flow rate, or if the machine is not calibrated correctly. To ensure the correct flow rate is being delivered, it is important to check that the machine is calibrated properly and to ensure the flow rate is set to the prescribed amount. If the flow rate is too high, it can cause discomfort or even airway obstruction, while a too low flow rate will not provide adequate oxygen therapy.

Issues with humidity

Another common issue with HFNC machines is delivering an incorrect level of humidity. This can occur if the machine is not set to the correct level, or if the level of humidity is not suitable for the patient’s condition. To ensure the correct level of humidity is delivered, it is important to check the machine is set to the correct level and to make sure the patient is comfortable with the level of humidity. Too much humidity can cause irritation and discomfort, while too little can cause dryness and discomfort.

Issues with pressure settings

The last common issue with HFNC machines is incorrect pressure settings. This can occur if the machine is not set to the correct pressure level or if the pressure is not suitable for the patient’s condition. To ensure the correct pressure level is delivered, it is important to check the machine is set to the proper setting and to make sure the patient is comfortable with the pressure level. Too much pressure can be uncomfortable, while too little pressure can cause inadequate oxygen delivery.

High flow nasal cannula machines can be a life-saving tool for patients with breathing difficulties. However, there are some common issues that can occur when using them. To ensure the machine is delivering the correct flow rate, humidity, and pressure levels, it is important to check the machine is calibrated properly and to ensure the settings are correct for the patient’s condition. With proper maintenance and troubleshooting, these machines can provide a reliable source of oxygen therapy for patients in need.
