2023年2月28日 · Here we divide oxygen delivery devices by the amount of flow delivered to the patient: “Low flow delivery devices” – deliver flows < 20 L/min to the patient “High flow delivery devices” – deliver flows >20 L/min to the patient

2022年4月1日 · High-flow oxygen delivery is a non-invasive respiratory support for critically ill patients to deliver very accurate oxygen concentration at flow rates that exceed patient’s respiratory requirements. It is usually defined as the administration of gas flow above 6 …

2021年7月1日 · High-Flow Nasal Cannula. High-Flow Nasal Cannula (HFNC) is a newer method of delivering a high flow and FIO2 of oxygen in patients who have higher oxygen requirements. COVID patients tend to do well on these devices, but it …

2023年4月6日 · High-flow nasal cannula (HFNC) therapy is an oxygen supply system capable of delivering up to 100% humidified and heated oxygen at a flow rate of up to 60 liters per minute. All settings are controlled independently, allowing for greater confidence in the delivery of supplemental oxygen as well as better outcomes when used.

2019年6月1日 · In the 2000s, less invasive high-flow nasal cannula (HFNC) therapy gained attention as an alternative means of respiratory support for patients who were critically ill. The HFNC system is simple: it requires only a flow generator, active heated humidifier, single heated circuit, and nasal cannula.

High-flow oxygen therapy is a form of respiratory support used in the hospital where oxygen, often in conjunction with compressed air and humidification, is delivered to a patient at rates of flow higher than that delivered in traditional oxygen therapy.

2019年4月12日 · Oxygen delivery systems are categorised into low-flow and high-flow systems. Low-flow systems provide lower oxygen flow than the actual inspiratory flow (∼30 L·min −1). When the patient inspires, the oxygen is diluted with room air, and the degree of dilution depends on the inspiratory flows.
