Researchers at Flinders University in Australia have developed a new micromedical device that continuously monitors blood flow during cardiac surgery.
The cardiac output monitor incorporates a tiny fiber optic sensor for real-time blood flow measurement. It can be inserted via a small keyhole-shaped opening in the skin and in the femoral artery.
According to the team, the heart lead could be better than standard approaches to monitor blood flow in the aorta during extended critical care and surgical procedures.
The researchers believe that the sensor-catheter device has the potential to save lives during open-heart surgery and that it can be used during the surgery of a premature baby.
John Arkwright, professor of strategy and research director at Flinders University, said: "The minimally invasive device is suitable for newborns and adults.
"This is a much more sensitive measure than traditional blood flow monitoring – and no lethal delays for the" instant "period provided by current blood flow practices using ultrasound or thermo-dilution."
Dr. Scott Morris of the College of Medicine and Public Health at Flinders University added that the new device could offer advantages over existing methods that provide intermittent measurements of average blood flow.
Researchers are currently seeking partnerships with the industry to further develop the device.
Dr. Albert Ruiz-Vargas, chief investigator for research, said, "The Proof of Concept prototype is potentially an inexpensive device that has pbaded initial tests in a heart-lung machine.
"It's a simple design that can give similar readings to a pulsed heartbeat on a laptop or screen nearby."
The team intends to conduct additional research on the operation of the new sensor under more physiological conditions. They will also evaluate various encapsulations that focus on human security.
