Abstract:
The underlying processes in vasculogenic erectile dysfunction (ED) are arterial insufficiency, venoocclusive disease, or combinations of both. Doppler blood flow analysis is a diagnostic modality useful in elucidating the cause of ED and the magnitude of its severity. This article describes the procedural techniques, typical findings, and relevant pathophysiology for in-office Doppler studies. Specific conditions include arterial insufficiency, venous occlusive disease, Peyronie's disease, and priapism.

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...
