“…It is not possible to achieve a very high inspired oxygen concentration near 100% by flooding the isolette with oxygen. Instead, a hood should be placed over the face as described by Jones et al 11 and Shannon et al 12 The duration of breathing increased oxygen concentrations is short (a few minutes) and thus poses no harm or the neonate. 2.…”

“…While breathing 95-100% oxygen, their mean arterial oxygen tension was 54 mmHg, and very few were over 150 mmHg. Shannon et al 12 noted that supplying 100% oxygen by positive endexpiratory pressure reduced the arterial oxygen tension in cyanotic neonates but increased it from an average of 66 mmHg on room air to 207 mmHg on oxygen in those with pulmonary problems.…”

AbstractPulse oximetry for detecting critical CHD produces more false positive tests at high altitudes than at sea level, because at altitude the average resting saturation is lower and the variability is higher. This increases diagnostic difficulties, especially in small isolated communities without paediatric echocardio-graphy, and requires expensive transport to a regional medical centre. One way of reducing diagnostic errors is to measure arterial oxygen saturation while the infant is breathing 100% oxygen. In the absence of right-to-left shunting through the heart, the ductus, or the lungs, arterial oxygen tension will exceed 150 mmHg and arterial oxygen saturation will be 100%. With right-to-left shunting, arterial oxygen tension will be <100 mmHg, and thus <96% (usually much lower).
