A sоnоgrаpher is evаluаting a patient with a suspected Internal Carоtid Artery (ICA) occlusion. Using standard carotid settings (PRF 3.0 kHz, medium wall filter), no color or spectral flow is detected in the distal ICA. To rule out a "trickle flow" near-occlusion, which combination of machine adjustments must be made to maximize sensitivity for low-velocity blood flow?
