When do you use high flow oxygen vs low flow?

When do you use high flow oxygen vs low flow?

Low-flow systems often are more comfortable, but the ability to deliver a precise oxygen concentration in various respiratory breathing patterns is limited. A high-flow system can deliver very accurate oxygen concentrations, but is often uncomfortable and obtrusive.

What is the difference between high flow oxygen and regular oxygen?

High-flow nasal oxygen (HFNO) therapy is an alternative to standard oxygen. By providing warmed and humidified gas, HFNO allows the delivery of higher flow rates via nasal cannula devices, with FiO2 values of nearly 100%.

When do you use high flow oxygen?

High flow oxygen therapy is for in people in respiratory distress who still have low oxygen levels despite trying traditional oxygen therapy. High flow oxygen therapy supports breathing in people with: Acute heart failure. Acute Respiratory Distress Syndrome (ARDS)

Is the oxygen delivery system use for the lowest flow of oxygen?

Oxygen delivery systems. 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.

Why do we use high-flow nasal cannula?

A high-flow nasal cannula accomplishes a reduction of nasopharyngeal airway resistance, leading to improved ventilation and oxygenation through the application of a positive pressure environment.

Is high-flow better than non-rebreather?

HFNC delivers flow, not pressure like CPAP or BiPAP, but the flow can generate an estimated 2-5 cm H2O of PEEP. HFNC is a better oxygen delivery and respiratory support device than the standard non-rebreather oxygen mask, venturi-mask, and simple low flow nasal cannula in a hypoxic patient.

Is high flow better than non-rebreather?

Is high flow better than non rebreather?

Is a non rebreather high-flow oxygen?

Non-rebreather masks are used to deliver oxygen therapy to people who require high-concentration oxygen but aren’t in need of breathing assistance. They’re considered low-flow oxygen delivery systems.

What is the difference between high-flow and low-flow?

Thus, if the ventilatory demand of the patient is met completely by the system, then it is a high-flow system. In contrast, if the system fails to meet the ventilatory demand of the patient, then it is classified as a low-flow system.

What is the difference between nasal cannula and high-flow nasal cannula?

When high-flow nasal cannula, or HFNC, is used to deliver oxygen, the flow rates are much higher than can be achieved with traditional nasal cannula. This results in a greater delivery of prescribed oxygen into the lungs, and less entrainment of room air.

Is a non-rebreather mask considered high flow oxygen?

The authors have used nonrebreather masks, which are low-flow oxygen delivery systems that generally provide oxygen at flow rates lower than the patient’s inspiratory demands. In other low-flow systems, if the total minute ventilation exceeds the flow capacity of the oxygen reservoir, room air is entrained (2).
