Point-of-care testing (POCT) is a delivery option for performing laboratory testing closer to the patient. Due to increasing healthcare pressures for faster turnaround of laboratory results and the development of a broader menu of testing devices, POCT is growing in popularity. Devices today are more portable,...

Our ability to assess the oxygenation status in critical care with a high degree of accuracy has improved as a result of recent developments in optical technology. The determination of the oxygenation status, however, remains a complex issue due to its multifaceted nature. This review discusses the definitions,...

The possibility of continuously monitoring arterial blood oxygen and carbon dioxide using heated surface electrodes on human skin was discovered in the early 1970s and made commercially available by 1976.  These devices were applied initially to premature infants in an effort to reduce the incidence of blindness due...

Postoperative monitoring in critical care patients has become a widening field over the past few decades. Improvements in outcome can be related to advances in this field as well as in intraoperative management and preoperative assessment.

The use of transcutaneous equipment is an essential element in the daily monitoring of neonates. To ensure reliable results and as little discomfort to neonates as possible, new staff members must be trained thoroughly. Nurse Åse Hansen, from the Copenhagen County Hosital, runs through the basic elements of staff...

Measurement of transcutaneous oxygen tension (tcpO₂) has gained worldwide acceptance as a simple and effective method of evaluating cutaneous blood flow in settings where skin viability and the adequacy of skin blood flow are of major concern. An example of such a setting is the non-invasive vascular laboratory at...

Assessment of tcpO₂ before and during hyperbaric oxygen treatment predicts the chance for a successful outcome.

Transcutaneous monitoring of carbon dioxide plays an important role during short-term and long-term treatments for ventilatory failure. Progress during short-term treatments can be judged through tcpCO₂ recordings - especially to avoid crash reintubation of patients who have been weaned off invasive ventilation....
