EU Sees Launch of Lab-Accurate Blood Gas Monitoring at Bedside

Critical care monitoring and diagnostics equipment company, Sphere Medical is to launch its ground-breaking in-line patient dedicated arterial blood gas analyser in Germany, Netherlands and Belgium. The launch will take place at this year’s Intensive Care and Emergency Medicine bash later this month.

Background

Based in Cambridge, UK, Sphere Medical’s new Proxima miniaturised blood gas analyser will be showcased for the first time in mainland Europe at the forthcoming 35th International Symposium on Intensive Care and Emergency Medicine (ISICEM), Brussels, 17-20th March 2015.

Sphere says its system uniquely delivers true point-of-care testing (POCT) by enabling critical care staff to obtain frequent “laboratory accurate” blood gas measurements without leaving the patient’s bedside. This facilitates effective and timely clinical decisions for proactive critical care.

The Proxima system is CE marked, so can be sold in Europe and represents a revolutionary concept in POCT, being attached directly to the patient through their arterial line. The miniature Proxima Sensor, containing a range of biological sensors, sits in series in the arterial line with the blood pressure transducer. The upshot is that for the first time, blood gas results can be delivered, like blood pressure results, within the patient’s bed space.

The system has already been fully evaluated and validated in a clinical setting. A recent observational method comparison study at Queen Elizabeth Hospital, Birmingham, UK, confirmed excellent agreement between Proxima and standard bench top blood gas analysers at the hospital. The trial assessed various arterial blood parameters of intensive care unit patients with a range of clinical conditions, including trauma, head injury, post-surgical recovery and sepsis.

Physician comments

Commenting on the clinical importance of Proxima, Dr. Tom Clutton-Brock, Senior Lecturer Anaesthesia and Intensive Care Medicine, University Hospital Birmingham, said, “Rapid return of data and swift response to changing blood gases is as essential in patient care as the continual measurement of blood pressure. Fast feedback and response could have a real impact on efficiently stabilising patients or weaning them from mechanical ventilation.”

Dr. Clutton-Brock will be presenting at ISICEM 2015 on ‘Bedside Blood Analysis’ within the Respiratory Monitoring Session, Salle M, 8.15am, Friday 20th March. This will discuss how frequent measurement of arterial blood samples is a key component in the effective management of patients in the critical care environment, particularly for those that are unstable. A scientific poster has also been accepted for presentation at ISICEM; ‘Evaluation of a patient dedicated blood gas analyser’ by Dr. Clutton-Brock and Dr. Jess Fox (Sphere Medical) will discuss the excellent results of the Queen Elizabeth Hospital method comparison study.
