Pulse oximetry is becoming popular for measuring oxygen saturation of haemoglobin in paediatric patients. There are no reference values for children living at high altitudes, and the aim of this study was to determine the values of oxygen saturation of haemoglobin in healthy children in Bogota (2640 m above sea level).The saturation was determined in 189 children aged 5 days to 24 months with a Nellcor N1O oximeter. Mean values and 95% confidence intervals (CI) were calculated. Analysis of variance was used for assessing the differences in saturation with age and physiological status. The values were normally distributed with a mean (SD) of 93-3 (2-05)% and 95% CI of 93.0% to 93-6%. There were no clinically important differences in the oxygen saturation of haemoglobin in the range of ages included. The mean saturation in sleeping children was significantly lower than that during other physiological states (91-1% v 93-3%) but the difference was not clinically important.As expected, the values for the oxygen saturation of haemoglobin in the children studied were lower than those reported from children living at sea level. These estimates can be used for interpreting results of the oxygen saturation in haemoglobin in children from Bogota and other cities located at a similar altitude.

“…Pulse oximeters use a spectrophotometric technique to determine the SaO,. The potential errors of this technique have been detailed (Huch et al 1988), and include interference from other haemoglobin species apart from oxy and deoxy haemoglobin A. However, the absorbance of oxy and deoxy haemoglobin S at the wavelengths used in pulse oximetry are thought to be similar to those of haemoglobin A.…”

Summary The place of pulse oximetry in monitoring arterial oxygen saturation in sickle cell disease has been evaluated. In four admissions of patients with sickle cell anaemia with varying degrees of arterial haemoglobin oxygen desaturation, pulse oximetry was compared with a simultaneous assessment of oxygen saturation by arterial blood gas measurement and oxygen dissociation curve (ODC) analysis. Close agreement was found between the oxygen saturation measured by pulse oximetry and that calculated from the measured arterial partial pressure of oxygen (PaO2) with reference to the patient's own ODC. Calculation of oxygen saturation by the blood gas analyser assuming a normal ODC was erroneous. Pulse oximetry is an accurate and effective non‐invasive method for monitoring the arterial oxygen saturation in sickle cell disease.

“…The contact PPG sensor is used in commercially available pulse oximeters, which use only two wavelengths, an arrangement that assumes the presence of only haemoglobin and oxyhaemoglobin in the blood. The presence of other species of haemoglobin such as carboxyhaemoglobin and methaemoglobin in the blood has been proven to lead to measurement errors [11], as well as other factors such as Development of effective photoplethysmographic measurement techniques: from contact to non-contact and from point to imaging…”

This paper provides an overview of the most recent developments in photoplethysmography (PPG). Existing contact point measurement techniques, i.e. pulse oximetry probes, are contrasted with the next generation non-contact and imaging implementations, i.e. non-contact reflection and camera-based PPG. The development of effective PPG monitoring techniques relies on novel approaches to opto-physiological modeling.
