This is a pilot study done to compare the effectiveness of
measurement of arterial hemoglobin saturation (SpO2), by a
newer device manufactured by Indian Institute of Technology
(IIT), Palakkad, Kerala and its readings were compared to that
measured by Standard multipara monitor by Nellcor/BPL,
India, in patients admitted in ICUs. In comparison to standard
multipara monitor the pulse plethysmograph oximeter showed
a good level of agreement (LOA: mean difference of only
-0.2 (95% CI limits -0.59 to 0.13) with statistically significant
correlation (0.848), concluding that the study device is effective
and reliable in measuring the SpO2.
