High Flow And Low Flow Oxygen Devices

High flow nasal interface improves oxygenation in patients undergoing bronchoscopy.

High flow and low flow oxygen devices. High flow nasal cannula. So low flow basically means you will be inhaling a mixture of supplemental oxygen plus room air. High flow the fio2 is fixed and meets the demand of the pt. The hfnc is an oxygen delivery system that includes an air oxygen blender humidifier heater and nasal cannula to deliver precise and very high flow oxygen to your patient.

Thus when the total ventilation exceeds the capacity of the oxygen reservoir room air is entrained. Oxygen therapy can be delivered using a low flow or high flow system.

The humidifier should always be placed at a level below the patient s head. In other low flow systems if the total minute ventilation exceeds the flow capacity of the oxygen reservoir room air is entrained. Low flow delivery devices. Oxygen delivery systems are generally classified as low flow or variable performance devices and high flow or fixed performance devices.

Indications for oxygen use low ambient o2 hypoxemia suspected hypoxemia increased work of breathing flaring tachypnea increased myocardial work acute head injury o2 delivery systems high flow venti masks air entrainment masks mechanical aerosol systems high flow humidifier systems low flow nasal cannula simple masks partial rebreathing masks. High flow oxygen therapy in acute respiratory failure. Oxygen delivery devices range from very simple and inexpensive designs to more complex and costly. Low flow is varible and does not meet the demand of the pt.

Respiratory care low high flow o2 and devices. Oxygen administration can be delivered via low flow or high flow systems with humidity or not and with a reservoir or not. I defined this in the above linked to post. These are oxygen devices that supply you with supplemental 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. Oxygen percentage delivery can be inconsistent or precise depending on the type of administration device selected. All high flow systems require humidification.
