Abstract

Abstract

Background

Acute lower respiratory infections (ALRI) is a major cause of deaths in children worldwide. In ALRI hypoxemia is the most common fatal complication. The WHO definition of hypoxemia  does not take into account the altitude The objective of this study is to determine the oxygen saturation value in apparently healthy under-five children who permanently reside at moderate altitude, Addis Ababa, Ethiopia using pulse oximetry. 

Methods

The study was a cross sectional design. The location of the study was at 2 health facilities in Addis Ababa. The SpO2 was measured among apparently healthy under-five year children using Nellcor N-10 self-calibrating pulse oximetry between May and July, 2017. A structured questionnaire was used to collect socio-demographic and clinical data. Data were entered and analyzed using SPSS version 20 statistical software.

Results

The mean SpO2 was 93.59% (95% CI 93.06%, 94.11%) with a median of 94.67%.  The 2.5th centile threshold of SpO2 for hypoxemia is 82%. Using suggested formula for hypoxemia threshold for the altitude of Addis Ababa is 90%. A significant difference was observed in SpO2 between infants and older children, although the difference was not demonstrable when sleeping subjects were excluded. Activities affect SpO2 whereby sleep and bottle or breast feeding had a lowering effect on SpO2.

Conclusions

This study provided a reference range of SpO2 values for healthy children under-five years of age. To determine the threshold for hypoxemia needs further clinically relevant cutoff.

Key words:

  • Moderate altitude, oxygen saturation, children under-five-year
