A decrease in which of the following tends to increase pulse pressure?
High-Yield Explanation
Type of BP Major determinant Systolic BP (SBP) SV (directly propoional) Compliance of aoa (inversely propoional) Diastolic BP (DBP) Elastic recoli of aoa / major vessels (directly propoional) Total peripheral resistance (directly propoional) Pulse pressure (PP) = SBP-DBP Ratio of stroke volume to compliance of the aerial tree Mean aerial pressure (MAP) = (SBP +2* DBP)/3 = DBP +(PP/3) Cardiac output x Total peripheral resistance
