Simply input the childs weight in kg his or her respiratory rate the current O 2 flow rate.
. High Flow Nasal Cannula Flow Rates. AU arbitrary unit. High-flow nasal cannula HFNC therapy is an oxygen supply system capable of delivering up to 100 humidified and heated oxygen at a flow rate of up to 60 liters per minute.
Set oxygen flow rate up to 8 Lmin on pediatric tubing up to 60Lmin in adults 10Kg 2 L per kg per minute max flow 60 Lmin start off at 6Lmin and increase up to goal flow rate over a few minutes to allow patient to adjust to high. The second objective of this study was to compare the effect of breathing with the mouth open versus with the mouth closed on F IO 2 while receiving oxygen via nasal can - nula at each liter flow 1 6 Lmin for low-flow nasal can-nulas 6 15 Lmin for high-flow nasal. HFNC high-flow nasal cannula.
ΔPes change in esophageal pressure. Little is known about the optimal settings. We would obviously do this above room air 21.

The optimal HFNC rate to decrease effort of breathing for children less than 3 years old is between 15 and 2 Lkgmin with the greatest improvement expected in children. The flow rates used ranged from 10 Lmin to 60 Lmin and. Use this calculator to estimate the effective FiO 2 that low flow oxygen delivers.
EELZ end-expiratory lung impedance. Flows more than this can cause dryness to the nasal mucosa without much increase in the FiO2. In a review of NHF controlled studies using a systematic search of the PubMed database it was shown that.
