acutecaretesting.org has talked to Lyn Morelli, senior staff member in Specimen Collection and Pauline Lowe, Clinical Midwife and senior educator in NICU at the Womens and Childrens Hospital in Adelaide, South Australia about their local procedures for neonatal capillary blood gas sampling.

acutecaretesting.org: What is the role of capillary blood gases compared to arterial samples, pulse oximetry and transcutaneous monitoring of blood gases? 

Pauline Lowe: Capillary sampling is supplemental to continuous monitoring. It is used particularly in neonates that are considered stable enough not to require invasive monitoring. 

In all cases (both capillary and arterial) the oxygen saturations are noted at the time of sampling and results are compared to the saturation.
