Emerging demand for High-flow Nasal Cannula (HFNC) Therapy
The high-flow oxygen therapy consists of an air/oxygen blender, an active heated humidifier, a single heated circuit, and a nasal cannula which together delivered warm and adequately humidified gas at high flow with more predictable FIO2 than with other devices. For instance, the flow rate of a traditional nasal cannula ranges between 2–6 L/min which is sometimes inadequate for patients with respiratory distress. In such cases the, patient entrain room air into the lungs resulting in oxygen dilution owing to which the patient may not receive the precise amount of oxygen that is required/needed.
High-flow nasal cannula therapy is capable of delivering up to 100% humidified and heated oxygen at a flow rate of up to 60 liters per minute. Thus, several studies are being conducted to evaluate the clinical efficiencies of high-flow nasal cannula therapy.
Further, non-invasive ventilation (NIV) is primarily used as respiratory support in patients with diseases like COPD exacerbation. In such a situation, HFNC offers enhanced alveolar ventilation, and reduces anatomical dead space, with several other physiological effects (PEEP effect, good humidification) compared to NIV. Moreover, it is simple and easy which also attributes to the dramatically increasing demand for HFNC.
The WHO has estimated that each year approx. 15 million babies are born prematurely of which nearly 1 million children die due to complications of preterm birth. The availability of small, thin, tapered bi-nasal tubes which are designed to deliver oxygen or blended oxygen/air are been increasingly deployed for non-invasive respiratory support for preterm infants in NICU.
Thus, owing to the advantages associated with high-flow oxygen therapy, these devices are gaining attention as alternative respiratory support for patients who are critically ill and also for adults, pediatrics, and perinatal care. Hence, the emerging demand for the high-flow nasal cannula (HFNC) oxygen therapy is driving the growth of high-flow oxygen cannulas market.
