Key result
The Masimo Radical-7 pulse co-oximeter was less accurate than the HemoCue system, with 40% of readings within 1 g/dL of laboratory values compared to 90% for HemoCue (p < 0.001).
Why the study?
Does point-of-care haemoglobin measurement using Radical-7 pulse co-oximeter or HemoCue accurately reflect laboratory haemoglobin measurements in women undergoing caesarean section delivery?

HemoCue outperforms Radical-7 for point-of-care hemoglobin in caesarean patients; observational data leaves open need for prospective validation before changing practice.
Observational (n=137)
Does point-of-care haemoglobin measurement using Radical-7 pulse co-oximeter or HemoCue accurately reflect laboratory haemoglobin measurements in women undergoing caesarean section delivery?
Absolute Event Rate: 40% vs 90%
p-value: p=< 0.001
The HemoCue system is significantly more accurate than the Radical-7 pulse co-oximeter for point-of-care hemoglobin measurement in obstetric patients when compared to laboratory values.
Skelton et al. (2012) conducted an observational in Women undergoing caesarean section delivery (n=137). Masimo Rainbow SET Radical-7 pulse co-oximeter vs. HemoCue HB 201+ and laboratory measurements was evaluated on Readings within 1 g.dl(-1) of laboratory values (p=< 0.001). The Masimo Radical-7 pulse co-oximeter was less accurate than the HemoCue system, with 40% of readings within 1 g/dL of laboratory values compared to 90% for HemoCue (p < 0.001).
