Abstract:
According to National Institute of Clinical Excellence guidelines, the ankle-brachial pressure index coupled with a full clinical evaluation has been the mainstay of detecting peripheral arterial disease on its suspicion. However, this technique is not free of its own limitations in calcified arteries, ulcerative and diabetic patients. We introduce a new, novel, and effective assessment device (BlueDop) with a minimal learning curve that could overcome such barriers and serve as a valid replacement in perihospital settings.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
