SummaryTranscutaneous PO2 sensors have been developed over the past ten years from the same basic electrodes used in conventional blood gas machines. The skin is heated to enable the skin surface sensors to respond quickly to the gas tensions beneath them. PtcO2 is a variable which reflects the PO2 in the peripheral tissue. PtcO2 has its own range of normal values and it responds to cardiopulmonary changes which affect tissue oxygenation. In the majority of patients, those without decreased… Expand
Transcutaneous Oxygen Monitoring
TLDR
This chapter will review the development of PtcO2 as a monitoring technique and relate it to other oxygen transport variables. Expand
Transcutaneous monitors during one-lung ventilation: are they reliable?
TLDR
It is concluded that transcutaneous monitoring is useful to indicate trends in arterial values in some patients, but blood gas analysis is still necessary to verify the reliability of such monitoring. Expand
Transorally obtained oxygen tension as an indicator of arterial oxygen tension
TLDR
The PtoO2 was linearly related to the PaO2, although its accuracy in reflecting PaO1 was low, which correlates with previously published data that suggested that the Pto O2 reflects tissue oxygen tension rather than arterialized oxygen tension. Expand
Determination of reference ranges for transcutaneous oxygen and carbon dioxide tension and the oxygen challenge test in healthy and morbidly obese subjects.
TLDR
Reference ranges were determined for transcutaneous oxygen and carbon dioxide tension and the Oxygen Challenge Test in obese and in normal, healthy subjects, and a negative correlation was found between trans cutaneous oxygen on room air and the oxygen challenge test versus body mass index. Expand
Assessing oxygenation in the transport environment
TLDR
The limitations of the physical examination, arterial blood gas measurements, transcutaneous monitoring, and pulse oximetry in determining a patient's oxygenation status are discussed. Expand
Influence of external pressure on transcutaneous oxygen tension and laser Doppler flowmetry on sacral skin.
TLDR
Using a non-linear regression model, a fourth degree polynomial is found to describe the relationship between tcpO2 and SKBF according to increasing pressure. Expand
Transcutaneous Po2 Monitoring During Treatment with Continuous Positive Airway Pressure in Infants with Idiopathic Respiratory Distress Syndrome
TLDR
It is proposed that Ptco2 monitoring should now be the method of choice and that the use of umbilical artery catheterization should be restricted to selected groups of very low birth‐weight infants and to infants in need of ventilator therapy. Expand
The Effect of Nursing Interventions on Transcutaneous Oxygen and Carbon Dioxide Tensions
TLDR
The results suggest that the physical activity associated with nursing interventions may significantly improve oxygen levels in the skin by stimulating overall cutaneous circulation. Expand
An evaluation of the use of transcutaneous oxygen pressure measurement in the non-invasive vascular laboratory : with special reference to selection of amputation level.
TLDR
This study establishes a value for the use of the TCp02 Index to predict amputation wound healing potential and examines the hypothesis that theUse of the TcpO~ Index to select amputation level can reduce patient morbidity and mortality. Expand
Transcutaneous Pco2 and Po2: A multicenter study of accuracy
TLDR
The data suggest that, using transcutaneous PCO2 monitors with inbuilt temperature correction of 4.5%/‡C, the skin metabolic offset should be set to 6 mm Hg, and within both groups errors were significantly greater above but not below 80mm Hg. Expand

Clinical Limitations and Advantages of Transcutaneous Oxygen Electrodes
TLDR
It is concluded that the transcutaneous oxygen electrode is safe, is easy to use, has few limitations and provides data which can help improve the management of most sick infants. Expand
Effects of hypoxia and shock on transcutaneous Po2 values in dogs
TLDR
It was concluded that the PtcO2 is an accurate, noninvasive, continuous method for monitoring peripheral oxygen delivery and a valuable tool for the study of disturbed circulation in various shock states. Expand
The validity of the transcutaneous oxygen tension method in adults.
TLDR
If one or two arterial blood measurements are performed, low as well as high Pao2 values may be predicted from tcPo2 in patients without gross circulatory impairment in healthy persons. Expand
Reliability of transcutaneous monitoring of arterial Po2 in newborn infants
TLDR
Comparison of transcutaneous and arterial blood Po2 values correlated quite well with arterial values within the whole Po2 range, the correlation being particularly satisfactory in the Po2range below 100 mmHg. Expand
Use of transcutaneous oxygen sensors to titrate PEEP.
TLDR
The continuous noninvasive nature of PtcO2 monitoring greatly increased the safety and simplicity of PEEP optimization and respiratory management of adult patients with respiratory failure. Expand

TLDR
The transition function of transcutaneous PO2 after a step change of inspiratory oxygen concentration is determined mainly by the alveolar ventilation and the ventilation-perfusion inhomogeneity. Expand

The results show a close correlation of PO2 values measured by the noninvasive method, in blood from discret arterial punctures, chamber PO2, respectively, the PO2 of the inspiratory gas mixture which was checked up to maximal values of 2,200 mm Hg. Expand
Dermal Heat Transport Analysis for Transcutaneous O2 Measurement
TLDR
The following equation is the steady state solution of the heat transport problem: heat being conducted in from the electrode and carried out by two means: conduction to deep tissue; and transport away by the flowing capillary blood. Expand
Use of a Transcutaneous PO2 Regional Perfusion Index to Quantify Tissue Perfusion in Peripheral Vascular Disease
TLDR
The authors find that transcutaneous oximetry can be used during treadmill exercise testing and that the RPI is unchanged by exercise in all normal subjects, and positive findings are, therefore, highly specific for exercise-induced limb ischemia. Expand
