Editing Pulse pressure (section)

== Calculation ==
Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure.<ref name="Cleveland Clinic 2021"/><ref>{{cite web | vauthors = Weber CO | date = 24 February 2022 | veditors = Shah A | url = http://highbloodpressure.about.com/od/highbloodpressure101/p/pulse_pressure.htm | archive-url = https://web.archive.org/web/20090217151343/http://highbloodpressure.about.com/od/highbloodpressure101/p/pulse_pressure.htm | archive-date = 17 February 2009 | title = Pulse Pressure | work = about.com }}</ref>

The systemic pulse pressure is approximately proportional to [[stroke volume]], or the amount of blood ejected from the [[Left Ventricle|left ventricle]] during [[systole]] (pump action) and inversely proportional to the [[compliance (physiology)|compliance]] (similar to [[Elasticity (physics)|elasticity]]) of the [[aorta]].<ref>{{cite web | vauthors = Klabunde RE | date = 29 March 2007 | work = Cardiovascular Physiology Concepts| url = http://www.cvphysiology.com/Blood%20Pressure/BP003.htm | archive-url = https://web.archive.org/web/20080516033607/http://www.cvphysiology.com/Blood%20Pressure/BP003.htm | archive-date = 16 May 2008 | title = Arterial pulse pressure }}</ref>

* ''Systemic pulse pressure'' (most commonly measured at the [[brachial artery]] in the upper arm using a [[Sphygmomanometer]]) = {{nobr|P<sub>systolic</sub> − P<sub>diastolic</sub>}}
:e.g. normal 120&nbsp;mmHg – 80&nbsp;mmHg = 40&nbsp;mmHg<ref name="Cleveland Clinic 2021"/>
: low: {{nobr|100&nbsp;mmHg − 80&nbsp;mmHg {{=}} 20&nbsp;mmHg}}
: high: {{nobr|160&nbsp;mmHg − 80&nbsp;mmHg {{=}} 80&nbsp;mmHg}}

* ''Pulmonary pulse pressure'' is normally much lower than systemic blood pressure due to the higher compliance of the pulmonary system compared to the arterial circulation.<ref>{{cite journal | vauthors = Blacher J, Evans A, Arveiler D, Amouyel P, Ferrières J, Bingham A, Yarnell J, Haas B, Montaye M, Ruidavets JB, Ducimetière P | display-authors = 3 | title = Residual cardiovascular risk in treated hypertension and hyperlipidaemia: the PRIME Study | journal = Journal of Human Hypertension | volume = 24 | issue = 1 | pages = 19–26 | date = January 2010 | pmid = 19474798 | doi = 10.1038/jhh.2009.34 | s2cid = 24409022 | author12 = PRIME Study Group | url = https://pure.qub.ac.uk/ws/files/632832/Residual%20cardiovascular%20risk%20in%20treated%20hypertension%20and%20hyperlipidaemia%20-%20the%20PRIME%20Study%20-%20J%20Hum%20Hypertens%202010%20-%20Evans%20AE,%20Yarnell%20JW..pdf }}</ref> It is measured by [[Pulmonary artery catheter|right heart catheterization]] or may be estimated by [[Echocardiography#Transthoracic echocardiogram|transthoracic echocardiography]].
