Association of transcutaneous CO<sub>2</sub> with respiratory support: a prospective double blind observational study in children with bronchiolitis and reactive airway disease.

Even though odds of escalation of care are higher with abnormal TcpCO 2 (OR 1.92), this difference did not reach statistical significance. pCO 2 can provide additive information for non-invasive clinical monitoring of children requiring varying respiratory support; however, it does not provide predictive value for escalation or de-escalation of care.
