Pulse pressure, the difference between systolic and diastolic blood pressure, is a key indicator of cardiovascular health, especially in the elderly. It predicts cardiovascular events, with higher values indicating increased risk. This text explores the relationship between systolic and diastolic pressures, pulse pressure variation in sepsis, and the determinants of mean arterial pressure. It also discusses the mechanisms regulating arterial blood pressure, including the baroreceptor reflex and the renin-angiotensin system, and the techniques for measuring blood pressure across different species.
