However, after birth, the presence of HbF becomes a disadvantage. This is because the P50 value of fetal blood is ∼3.6 kPa compared with 4.8 kPa in adult blood. …
WebAlthough the wall oxygen supply is a concentration of 100%, the actual concentration of oxygen the patient receives will vary according to the apparatus used and the flow. A mixture of air and oxygen occurs at different flows depending on the patient’s minute volume and whether the child is an oral or nasal breather. WebWhen tubing was used below the face, flow rates between 6 and 8 L/min produced somewhat higher concentrations than 15 L/min (5 cm: 36.3% vs. 30.9%). Conclusions: When delivering oxygen by wafting, the highest oxygen concentrations are achieved when positioning tubing 5-15 cm in front of the face or positioning tubing or a paediatric …
