What are the limitations of transcutaneous PO2 (PtcO2)?
What will be an ideal response?
Accuracy of the PtcO2 electrode is affected by skin edema, hypothermia, and capillary perfusion status. PtcO2 becomes less accurate when the measuring range is greater than 80 mm Hg. When cardiac output decreases, as with the patient in shock, a disproportionate fall in PtcO2 occurs. Other disadvantages of transcutaneous monitors are the need for frequent site changes (every 4 hours) to avoid erythemia and burns to the infant's skin, and a long equilibration time after each site change.
