Oxygen was administrated via the high flow NC (model ref 1600, Salter Labs, mean FiO2 than the SM at flows of 6-10 L/min; at 12 L/min the delivered FiO2 4 Nov 2009 We compared FiO2 delivery of the OxyMask to other common devices over a A nasal cannula and OxyMask were also compared at 2 L/min. 10 Jul 2013 Nasal Cannula: FiO2 24-44% at 1-6 L/min; client is able to eat, talk and ambulate, watch for skin breakdown and dry mucous membranes and 15 Apr 2020 Nasal Cannula (NC): Start with a NC at 5-6 liters per minute (LPM). This is the ratio of oxygen saturation over FiO2 over respiratory rate. Weight-based HFNC flow rate using the patient's FiO2 from before the 1-2 L /min flow trial.

For every liter per minute, the FiO2 increases by 4% as per the chart below: 1 lpm = 24%; 2 lpm = 28%; 3 lpm = 32%; 4 lpm = 36%; 5 lpm = 40%; 6 lpm = 44% Room air is 21% oxygen. For every liter of oxygen delivered by nasal cannula add 4% for example: 1L= 24% 2L=28% 3L=32% and so on. 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.

VENTURI FACE MASK AKA VENTI MASK • Delivers a precise FiO2 • FiO2 can be set in a range from 24% to 50% with model used here • Can also be used for transports on a trach collar • Indications: Mouth breather, precise FiO2 needed, increased flow demand, patient unable to wear NC FIO2 course when using 0.7 L/min O2/N2O with 29%O2 in a circle breathing system with an anesthesia machine with an active inspired hypoxic guard.If an adult 10 l/min 80 -90 % O 2 12-15 l/min ca 90 % O2 .
