Transcutaneous estimation of arterial PO2 and PCO2 in newborn infants with a single electrochemical sensor
Abstract
A transcutaneous electrochemical sensor designed to estimate arterial oxygen (PaO2) and carbon dioxide (PaCO2) tensions simultaneously and continuously was evaluated in newborn infants with respiratory illnesses. After calibration of the sensor against a sample of arterial blood from the infant, the accuracy of estimation of PaO2 and PaCO2 seemed sufficient for clinical purposes.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
