What percentage of oxygen is delivered per nasal cannula at 6 liters a minute?

Answer 1

I don't understand the Related Link well enough to know if it answers your question, but you can check it out and see if it does.

The percentage of oxygen delivered by nasal tube is 24% at the rate of 1 L/min, 28% @2l/min, and so on with a 4% increase per litre of flow per minute to a maximum of 60%.

Answer 2

Room air is 20%. 0ne Liter increases the FIO2 4%. So 1L =24%, 2L=28% and so on to 6L=44%, do not use a cannula above 6 lmp. Becomes uncomfortable and dries out the nares and can cause bloody noses due to lost humidity.

Answer 3

One study states that the FiO2 at 6L NC is 54% (plus minus 13%).

A rule of thumb is that for each liter flow through a nasal cannula, you add 4% to room air 21% FiO2. Not perfect but a good rough estimate

Answer 4

Supplemental Oxygen comes out of the tank as %100 oxygen. When the flow rate is kept constant the oxygen being delivered out of the nasal cannual or prongs (N.P. as a shortened acronym) is coming out at %100 concentration. The patient is constantly mixing room air with pure oxygen and depending on the the respiratory rate, varying concentrations of oxygen will be received. (Higher respirations = more room air compared to pure oxygen, therefore lowering the amount of supplemental oxygen entering the lungs with each breath). Continued high respiratory rate would indicate a need for increased supplemental oxygen. If it is required a patient will need specifically controlled oxygen concentration (typically way higher than given through a nasal cannula or simple mask) a Venturi mask or wall mounted control dial with humidification will be used. This is only used in hospitals to maintain life, as alteration by an untrained individual could result in serious complications including lung collapse.

Answer 5

28% is the correct answer.

A quick way to estimate is to multiply the number of liters by three and add that to room air.

(2*3)+21%= ~27%

Answer 6

A little less than a broken fishstick.

Answer 7

2 to 4 lpm

Answer 8

55%
