However, continuous measurements would be preferred. Transcutaneous sensors continuously measure blood gases diffusing from the locally heated skin.

Patients were included when endotracheally intubated and provided with an arterial catheter for regular blood sampling. Patients with a gestational age &lt;31\u00a0weeks, burn victims, and patients with skin disease were excluded. TcPCO<jats:sub>2<\/jats:sub> and tcPO<jats:sub>2<\/jats:sub>\u00a0measurements were performed with a SenTec OxiVenT<jats:sup>\u2122<\/jats:sup> sensor (SenTec AG). Accuracy was determined with an agreement analysis between arterial and transcutaneous PCO<jats:sub>2<\/jats:sub> and PO<jats:sub>2<\/jats:sub>\u00a0values, and between arterial and endtidal PCO<jats:sub>2<\/jats:sub> (etCO<jats:sub>2<\/jats:sub>) values, according to Bland and Altman, accounting for multiple measurements per subject.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We included 53 patients (median age 4.1\u00a0years, IQR 0.7\u201314.4\u00a0years) and retrieved 175\u00a0samples.
