Does a newly developed pulse oximeter measuring SpO2 to one decimal point accurately correlate with SaO2 from arterial blood gas analysis?
A newly developed pulse oximeter that measures SpO2 to one decimal point correlates highly with arterial blood gas analysis, which may allow for more precise clinical assessment.
Effect estimate: r = 0.887
p-value: p=< 0.0001
Pulse oximeters are used to noninvasively measure oxygen saturation in arterial blood (SaO2). Although arterial oxygen saturation measured by pulse oximeter (SpO2) is usually indicated in 1% increments, the value of SaO2 from arterial blood gas analysis is not an integer. We have developed a new pulse oximeter that can measure SpO2 to one digit after the decimal point. The values of SpO2 from the newly developed pulse oximeter are highly correlated with the values of SaO2 from arterial blood gas analysis (SpO2 = 0.899 × SaO2 + 9.944, r = 0.887, P < 0.0001). This device may help improve the evaluation of pathological conditions in patients.
Yamamoto et al. (Sun,) conducted a observational in Respiratory diseases and other conditions requiring blood gas analysis (n=21). Newly developed pulse oximeter measuring SpO2 to one decimal point vs. Arterial blood gas analysis (SaO2) and conventional pulse oximeters (Nellcore, SmartPulse) was evaluated on Correlation between SpO2 from the newly developed pulse oximeter and SaO2 from arterial blood gas analysis (r = 0.887, p=< 0.0001). The newly developed pulse oximeter measuring SpO2 to one decimal point showed a high correlation with SaO2 from arterial blood gas analysis (r = 0.887, P < 0.0001).
