2、压： 物理学四定律,Ohms law:MAP = (heart rate SV SVR) + mRAPSimplified Windkessel model:Compliance = SV/aortic PPMAP = (2/3 DAP) + (1/3 SAP)Laplase Law: P2T/r,收缩压；舒张压，脉压差；心输出量,心率, 全身血管阻力，动脉顺应性,5,1. Ohms公式的意义: MAP = (heart rate SV SVR) + mRAP,SVR is not a measured parameter but is calculated from the measured
3、 values of MAP, CO and mRAP.Despite clear limitations in Poiseuilles Law when it is applied to the human circulation, it is generally believed that SVR is inversely proportional to the fourth power of the functional radius of the systemic network (mainly that of the distal resistive arteries). For a
4、 given MAP, SVR depends only on the value of CO, regardless of the way in which CO is generated (e.g. low SV/high heart rate or high SV/low heart rate).,6,平均动脉压（MAP)的意义,When MAP falls below the lower limit of autoregulation, regional blood flow becomes linearly dependent on MAP.,7,In some pathologic
5、al settings, MAP overestimates the true perfusion pressure,because of marked increases in extravascular pressure at the outflow level in specific vascular areas (intracranial hypertension, abdominal compartment syndrome) because of marked increases in systemic venous pressure (right heart failure).,
6、8,MAP:代偿机制受损时,Acute decreases in MAP are counteracted by the sympathetically mediated tachycardia, increases in SV (mediated via positive inotropic effect and veno-constriction) and arterial systemic vasoconstriction. In critically ill patients, especially those with sepsis or who are receiving seda
7、tive drugs, these compensatory mechanisms can be either impaired or overwhelmed.,9,2.脉压差(pulse pressure)的意义,Although it remains to be demonstrated, it is widely accepted that peripheral PP at rest depends mainly on SV and arterial stiffness (1/compliance) . In this regard, in older individuals incre
8、ased arterial stiffness leads to increased PP, and this results in systolic hypertension associated with decreased DAP. On the other hand, in patients with cardiogenic or hypovolaemic shock, decreased SV results in a lower PP.,10,Compliance = SV/aortic PP,The paradoxical finding of a low PP in the e
9、lderly and in patients with hypertension or atherosclerosis strongly suggests that SV is markedly low,because arterial stiffness is expected to be increased in these patients.,11,3. 血压指标间的关系MAP = (2/3 DAP) + (1/3 SAP),In clinical practice, differences in mean DAP values are believed to reflect mainl
10、y changes in vascular tone, with lower DAP corresponding to decreased vascular tone. As discussed above, and for a given MAP, increased arterial stiffness also tends to be associated with lower DAP (and higher SAP as well). According to the classic MAP empirical formula, and for a given MAP, an incr
11、ease in arterial stiffness increases SAP twofold more than it decreases DAP. Finally, from a beat-to-beat point of view, prolonged diastolic time is associated with lower DAP and shorter diastolic time with higher DAP.,12,4.Laplace Law,拉普拉斯定律: P2T/r 。 P 代表肺泡回缩力，T代表表面张力，r代表肺泡半径。肺回缩力与表面张力成正比，与肺泡的半径成反比
