For a patient on NC, to determine the FiO2, you multiply the number of liters by 4% and then add to 20% (which is an estimate of the % of oxygen in room air)

actual FiO2 delivered to neonates when using a low-flow flowmeter and a nasal cannula, and the accuracy with which FiO2 could be estimated using a formula that we developed. FiO2 measured = (O2 flow (ml/min) x 0.79) + (0.21 x V E) / V E x 100 • where minute ventilation (V E) equals the minute ventilation in mL/min (V E = VT X respiratory rate). A trach collar is effective at lower FiO2 just like the Venturi mask. There are a few high flow humidifiers which can go up to 40 or even 60 liters if demand is great. Sometimes the RTs will hook up two humidifiers on a Y connectors.

5 liters per minute of oxygen gives a FiO2 of 0.40. 6 liters per minute of oxygen gives a FiO2 of 0.44.

Sometimes the RTs will hook up two humidifiers on a Y connectors. They will run both humidifiers at the same FiO2 to achieve a more precise percentage.

Yes, its right but the formula of Lpm to FiO2 is: lpm*4+20 = FiO2 2013-12-15 · Too many get caught up in the 1 L = 24%, 2 L = 28% crap which is only good for exam purposes and does not address the many different devices for O2 delivery or the many patient factors which influence FiO2. PaO2/FiO2 ratio is the ratio of arterial oxygen partial pressure (PaO2 in mmHg) to fractional inspired oxygen (FiO2 expressed as a fraction, not a percentage) also known as the Horowitz index, the Carrico index, and (most conveniently) the P/F ratio; at sea level, the normal PaO2/FiO2 ratio is ~ 400-500 mmHg (~55-65 kPa) A reminder of the variability of FiO2 when oxygen is delivered via nasal cannulae at oxygen flow rates in 2–4 L/min as provided in the study by O'Reilly‐Nugent et al. 10 in this issue is timely. Their method of FiO2 measurement was novel in that they sampled the distal trachea after placement of a catheter via bronchoscopy rather than sampling more proximally in the nasopharynx.
