Note about pulse pressure; Histopathology review

Note about pulse pressure  (systolic minus diastolic BP)

Compliance = ΔV/ΔP

for arteries; compliance = ΔV=stroke volume; ΔP=pulse pressure

comliance = stroke volume/pulse pressure      so

pulse pressure = stroke volume/compliance

increased pulse pressure; e.g., 140/70 indicates either increased stroke volume OR decreased arterial compliance

Dr. Krinsky - histopathology review

lungs filter various types of emboli

amniotic fluid emboli produced during labor

inflammatory cells in asthma = eos
