A variety of interfaces specifically designed with Optiflow High Flow therapy in mind.Three temperature settings, (37, 34, 31 ☌) helps achieve comfort and compliance.A compact system with a built-in flow generator means there’s no need for a noisy, heavy air compressor in order to use the Airvo 2 for transport.A broad flow range (2 to 60 L/min) takes your patients from the most acute environments (ICU and ED) to the home.Airvo 2 has been proven to be effective in patients with acute hypoxemic respiratory failure, for post-extubation respiratory support, for postoperative respiratory support, for immunocompromised patients with acute hypoxemic respiratory failure and for patients with COPD.Fisher & Paykel AIRVO 2 Humidification High Flow System.We can clearly see the major benefits of HFNC as written below: The 5 best-selling HFNC machines Another way to say this is our dead-space increases with acute respiratory failure. As a result we can rebreathe larger amounts of carbon dioxide. In patients with acute respiratory failure, the percentage of gas we rebreathe gets larger. In fact it’s a mix of the new atmospheric gas (21% 02, negligible CO2) and their previously exhaled gas (<21% oxygen and some CO2). When you patient takes their next breath from atmospheric gas not all of that gas enters the alveoli. And is not fully exhaled and remains in the upper airway. This is because of previously exhaled breath (low in oxygen and with some carbon dioxide). Instead of breathing 21% (room air) and negligible amounts of carbon dioxide we may rebreathe more like 15-16% oxygen and 5-6% carbon dioxide. Washout of Dead-space: We normally rebreathe a third of our previously expired tidal volume. O2 Dilution: To deliver higher amounts of fiO2 effectively to your patient you have to not only match, but exceed your patient minute ventilation and inspiratory demands to minimize oxygen dilution. This may lead to higher compliance with HFNC and perhaps an improvement in your patient’s oxygenation and work of breathing. Because the warmed, humidified gases won’t dry their mucosa like standard oxygen therapy. Lighter: Patients often prefer the use of HFNC to that of non-invasive positive pressure ventilation (CPAP or BPAP) because the tight fitting mask can be uncomfortable to some patients. Therefore their peak inspiratory flows, which may normally be 30L/min – 60L/min, can reach up to 120 L/min. This is important as patients in acute respiratory failure can be extremely tachypneic. Inspiratory Demands: One obvious benefit, but worth mentioning is that high flow can give you a very high flow of gas. This may possibly leading to decrease secretion clearance. This can lead to airway inflammation, which can increase airway resistance and impair mucociliary function. Standard oxygen therapy delivered through a nasal cannula or another device such as a non-rebreather. Heated & Humidified: Heated and Humidified oxygen has a number of benefits compared to standard oxygen therapy. It depends on various key factors which are describes below: The flow rate and fi02 can be independently titrated based on your patient’s flow and fi02 requirements. It actually takes gas and can heat it to 37 o C with a 100% relative humidity and can deliver 0.21 – 1.00% fi02 at flow rates of up to 60 liters/min. ![]() Heat and humidified high flow nasal cannula or as most call it, Hi Flow Nasal Cannula (HFNC), isn’t just a standard nasal cannula cranked up to very high flow rates. Earlier it was used to treat children with severe bronchiolitis but now a days healthcare unit began to use it in the adult intensive care unit as well. The use of heated and humidified high flow nasal cannula (HFNC) has become increasingly popular in the treatment of patients with acute respiratory failure through all age groups. The role of noninvasive ventilation in those with chronic respiratory failure is not as clear and remains to be defined. Its use in acute respiratory failure is well accepted and widespread. Noninvasive ventilation has been used as a replacement for invasive ventilation, and its flexibility also allows it to be a valuable complement in patient management. The use of noninvasive ventilation (see the video below) has markedly increased over the past two decades, and noninvasive ventilation has now become an integral tool in the management of both acute and chronic respiratory failure, in both the home setting and in the critical care unit. Noninvasive ventilation (NIV) refers to the administration of ventilatory support without using an invasive artificial airway (endotracheal tube or tracheostomy tube). ![]()
