Oximeter for Extracoporeal Circulation:

Monitoring of blood gases during surgery with extracorporeal circulation is an important means of determining whether the tissue metabolism remains within acceptable range. Customarily in these situations, the oxygen saturation is evaluated by analyzing blood samples obtained from the patient. The main disadvantages of this approach are discontinuous measurements and a delay between sample withdrawal and analysis. Blood flow pattern lacks pulsatility to allow the use of pulse oximeters. The Oximeter for Extracorporeal Circulation is a novel optical transducer for continuous and real time monitoring of oxygen saturation bracing extracorporeal tubing during cardiopulmonary bypass.

Specifications:

• Oxygen saturation measurement range: 50 - 100%

• Power Supply: 110VAC, 60 Hz
• Dimensions: 22 x 20.5 x 9.5 mm (L x W x H)
• Weight: 3 kg
• UPS (optional): Battery operates up to 60 min
• Simple to use
• Arterial and venous SO2 alarms
