A Comparison of Two Transcutaneous Monitors for the Measurement of Arterial Po₂ and Pco₂ in Neonates

Abstract

We examined the ability of two transcutaneous devices (Fastrac,

Evaluation of a transcutaneous blood gas monitoring system in critically ill dogs

“…The AARC clinical practice guidelines state that while PtcCO 2 typically over‐estimates PaCO 2 , “…the acceptable clinical range of agreement for PtcCO 2 is ± 7.5 mm Hg.” Therefore, the PtcCO 2 measurements from the present study would not be considered clinically acceptable by AARC standards. In comparison with human studies, agreement between transcutaneous and arterial PO 2 and PCO 2 measurements was inferior in the present study, as most human studies show mean differences of < 5 mm Hg …”

Estimating inspired oxygen concentration delivered by nasal prongs in children with bronchiolitis

“…It was not practical to perform invasive PaO 2 measurements on children with bronchiolitis who were not in intensive care. TcPO 2 has been shown to be a reliable indicator of arterial oxygen tension within a certain range of PaO 2 values in children and adults 6–13 …”

“…TcPO 2 has been shown to be a reliable indicator of arterial oxygen tension within a certain range of PaO 2 values in children and adults. [6][7][8][9][10][11][12][13] Oxyhaemoglobin saturation values were poor predictors of change at high tcPO 2 levels, and decreased more dramatically with lower tcPO 2 levels. This follows the oxygen dissociation curve.…”

Nasal continuous positive airway pressure: does bubbling improve gas exchange?

“…4 TcCO 2 is easily measured and is closely related to arterial carbon dioxide (PaCO 2 ) over short time periods. 5 We decided to exploit these concepts to investigate whether bubbling that was vigorous, with a high amplitude, or slow influenced a baby's gas exchange.…”
