Brief Summary

Pulse oximetry is a well-established, non-invasive measurement tool used to estimate arterial oxygen saturation. The accuracy of these cheap, readily available finger pulse oximeters has not been robustly assessed in a clinical trial however. It is vital for clinical practice that this technology is reliable in tracking changes in oxygen saturations at times of ill health as varying physiological parameters may, in theory, contribute to inaccurate readings. This study will investigate whether these new devices provide a sufficiently accurate measurement of oxygen levels in the blood (when compared to arterial blood gas sampling) to endorse their use in routine hospital practice.

Conditions

Hypoxia; Respiratory Failure With Hypoxia

Outcome Measures

Primary Outcomes (1)

• Correlation

  The handheld pulse oximeters will exhibit a good correlation as evidenced by the Intraclass correlation coefficient of 0.75. The cohort patients who were deemed by their treating physician to require an arterial blood gas sample had simultaneous SpO2 readings using 3 pulse oximeters (TempIR-Oxy, Jumper JPD-500A and Nonin Vantage 9590). Data were analysed using Pearson correlation co-efficient (r) and Bland Altman bias plot.
