Flow rate 1 4l min 4l will dry the nose 2l is more comfortable.
High flow oxygen devices ppt.
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.
The humidifier should always be placed at a level below the patient s head.
Oxygen loss is negligible but with these devices high concentrations of oxygen are not available.
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.

Rightward shift facilitates unloading of o2 a 40 air entrainment 10l min o2 flow will produce a total gas flow of approximately 40l min 28 air entrainment 4 l min o2 flow will produce a total gas flow of approximately 44 l min.
High flow can thus be generated even though air and high pressure oxygen wall supplies are unavailable.
The system provides a high flow of heated humidified air to the patient via the nasal cannula.
High flow oxygen therapy systems used in the hospital environment usually consist of a blender used with or without oxygen from a wall outlet humidifier heated tubing and nasal cannula.
The flows are such that the patient will not be entraining room air that will lower the fio2.
High flow oxygen devices these devices meet the inspiratory flow of the patient and generate accurate fio2s so long as there is a good seal between the mask and the patient s face.
Page high flow gas delivery systems supply all the gas the patient needs.
Oxygen delivery devices 1.
Indications of o2 therapy 1.
The percentage of oxygen inspired depends on the flow rate and the delivery device.
Respiratory rate and tidal volume of the patient have no.
Low flow device most common device used for mild hypoxia can be set between 1 and 6 lpm 24 to 40 fio2 fio2 increases approximately 4 with each liter of o2 korupolur gj needham dm contemporary criticalcare.
Oxygen therapy can be delivered using a low flow or high flow system.
The flow rate can be set on the wall tap.
These devices monitor delivered oxygen concentration supplied via a low pressure system in the delivered gas.
All high flow systems require humidification.
The type of humidification device selected will depend on the oxygen delivery system in use and the patient s requirements.
In this video george gives a short review differentiating between high and low flow oxygen systems.
It varies from 0 15l per minute.
