The supply flow rate ranges up to 50 or 60 liters/min based on the design of the machines. Therefore, at 60 l/min, which is 1000 ml/s, the nasal cavity will be filled with fresh gas within a fraction of a second leading to rapid dilution and purging of the expired air.

30lpm flow recommended for ward based care humidification:
High flow nasal prongs flow rate. The below nasal cannula oxygen percentage chart shows the percentage of oxygen delivered against the flow rate. No need for humidification : Nasal high flow (nhf) therapy is recommended for use in several applications by published guidelines.
It actually takes gas and can heat it to 37 o c with a 100% relative humidity and can. This improves functional residual capacity thereby reducing work. Set oxygen flow rate (up to 8 l/min on pediatric tubing, up to 60l/min in adults) — >10kg 2 l per kg per minute (max flow 60 l/min)</strong> — start off at 6l/min and increase up to goal flow rate over a few minutes to allow patient to adjust to high flow
However, at the highest flow rate, the dead space clearance is likely to be maximized regardless of the cannula size. The value of fio 2 ranges from 21% to 41%. The humidification of the inhaled.
Heated, humidified, high flow nasal oxygen (hfno), a techniquethat can deliver heated and humidified oxygen, with a controlled fraction ofinspired oxygen (fio2), at a maximum flow rate of 60l/min via a. Once the flow rate reaches 35l/min the woman is no longer receiving high flow of oxygen and may benefit from standard low flow oxygen. If the woman is using the device for assistance with secretions she may continue to benefit hfnp
Ideally a ngt should be placed prior to initiation of nhf therapy and remain in situ for the duration of therapy. The supply flow rate ranges from 1 to 6 liters/min: Nonetheless, with this device, the fi o 2 is limited to a nominal 60%:
Nasal high flow (nhf) via the airvo™ 1 & 2 circuit is able to deliver a user set fixed fraction of inspired oxygen at high flow rates. What is a “high” gas flow rate is still not. Guidelines for maximum flow rates for nasal canula use the table below to identify the recommended litres of flow per kilogram per minute and which mode you require:
A logical step in the progression of this topic is to consider hfnc for apnoeic oxygenation. Maximum flows for children above 25kg are titrated according to age and weight (see flow rate table below). 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.
High flow systems for apnoeic oxygenation. Humidified high flow nasal cannula (hhfnc) therapy is a simple to use system that delivers warm, moist gas at high flow rates that generate positive airway pressure. An alternative to conventional oxygen therapy has receivedgrowing attention:
A clinical practice guideline for nhf use as a respiratory strategy in adult patients requiring respiratory support was recently published in intensive care medicine,1 the official journal of the european society of intensive care medicine (esicm). Ncpap/intubation, or provide support post extubation. The value of fio 2 ranges from 21% to 100%.
Humidified high flow nasal cannula therapy is the delivery of heated humidified air and / or oxygen via nasal prongs at a flow rate of 2l/kg/min for children up to 25kg.
