High flow oxygen devices ppt.

Oxygen delivery devices dr. Delivery devices work with different flow rates. High flow can thus be generated even though air and high pressure oxygen wall supplies are unavailable. Documented hypoxemia in adults children and infants older than 28 days arterial oxygen tension pao2 of 60 mmhg or arterial oxygen saturation sao2 of 90 in subjects breathing room air or with pao2 and or sao2 below desirable range for specific clinical situation in neonates pao2 50.

The percentage of oxygen inspired depends on the flow rate and the delivery device. 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. Oxygen loss is negligible but with these devices high concentrations of oxygen are not available. Respiratory rate and tidal volume of the patient have no.

Indications of o2 therapy 1. The flow rate can be set on the wall tap. Oxygen therapy can be delivered using a low flow or high flow system. The type of humidification device selected will depend on the oxygen delivery system in use and the patient s requirements.

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. It varies from 0 15l per minute. Flow rate 1 4l min 4l will dry the nose 2l is more comfortable. These devices monitor delivered oxygen concentration supplied via a low pressure system in the delivered gas.

Oxygen delivery devices 1. 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. They include nasal cannulae. 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.

All high flow systems require humidification. The humidifier should always be placed at a level below the patient s head. 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 system provides a high flow of heated humidified air to the patient via the nasal cannula.

In this video george gives a short review differentiating between high and low flow oxygen systems.
