Over the past few decades, almost every patient in the emergency department or intensive care unit has received some form of oxygen therapy with high flow, heating, and humidifying oxygen delivered through nasal intubation. 

This post will compare low flow nasal oxygen tubes with high flow nasal oxygen tubes to help you have a deeper understanding of nasal therapy.

Low Flow Nasal Cannula

Low flow systems are generally more comfortable but have limited ability to provide accurate oxygen concentrations in various breathing modes.

Low flow o2 delivery can only effectively provide 4 to 6 liters of supplemental oxygen per minute. This corresponds to a FiO2 of about 0.37 to 0.45. Beyond this figure, nasal mucosal irritation will occur with the drying of the channel. Therefore, long-term use will increase the possibility of bleeding.

Besides, in the treatment of low flow nasal intubation, the delivery of FIO2 is directly related to the flow rate. For increased FiO2, the rate must be increased. The low flow nasal cannula is an open replenishment system with a large amount of air leakage around the oxygen source. Therefore, the therapeutic effect of low flow nasal cannula is limited.

High Flow Nasal Cannula

High flow oxygen tubing has obvious advantages over other oxygen devices because of its unique role in respiratory physiology. In particular, adjustable oxygen delivery and flow-dependent carbon dioxide clearance reduce respiratory work and better match the inspiratory demand in respiratory distress.

But very precise oxygen concentration usually makes people feel uncomfortable and abrupt. The Oxygen Delivery Device provided by SUPERFIRT can provide accurate oxygen concentration at different flow rates and provide a certain degree of comfort for patients. Because it uses a molecular humidification system, it can increase moisture transfer and promote mucus movement, thus helping to prevent mucus blockage.

High flow nasal intubation (hfnc) therapy has become an increasingly popular treatment for hypoxic respiratory failure. (hfnc) therapy capable of delivering 100% humidified and heated oxygen at a flow rate of up to 60 L / min. All settings are independently controlled, which can provide supplemental oxygen more safely and obtain better results.
