| ox {MethComp} | R Documentation |
61 children had their blood oxygen content measured at the Children's
Hospital in Melbourne, either with a chemical method analysing gases in
the blood (CO) or by a pulse oximeter measuring transcutaneously
(pulse). Replicates are linked between methods; i.e. replicate 1
for each of the two methods are done at the same time. However,
replicate measurements were taken in quick succession so the pairs of
measurements are exchangeable within person.
