However, the true value of an accurate pulse oximeter lies in its ability to correctly identify a hypoxaemic
patient who would require prompt intervention.
Now evidence from secondary health facilities in Nigeria also shows that 25 per cent of newborns and 12 per cent of under-5 children admitted to hospital with pneumonia have insufficient oxygen in the blood or low blood oxygen saturation, what is medically termed hypoxaemic
episodes can be seen even with oxygen administration (9).
These metabolic factors lead to a hypercoagulable, hypoxaemic
and inflammatory state, increasing the risk for cardiac morbidity and mortality.2 In fact, myocardial injury and infarct after a non-cardiac surgery remain common and under diagnosed complications.3
She became increasingly hypoxaemic
and developed lactic acidosis and oliguria.

conditions," Life Sciences, vol.
Providing supplementary oxygen will increase oxygen delivery in hypoxaemic
patients, thus supporting cell function and metabolism and limiting organ dysfunction.

patients with pulmonary arteriovenous malformations," PLoS ONE, vol.
The normal physiological state of a fetus is best described as hypoxaemic
, with PH and reduced pulmonary blood flow, and with the placenta responsible for gas and nutrient exchange.
It also states that prior to discharge from hospital after an exacerbation, patients that remain hypoxaemic
should be assessed with either ABG and/or pulse oximetry and then reassessed within three months.
Of these patients, 23 (15.5%) were hypoxaemic
on arrival in the ICU.
Five more patients demised after 48 hours due to multiple organ dysfunction syndrome with sepsis, while care was withdrawn from one patient with severe hypoxaemic
