pparalphaA helpful equation is CO=rate of O2 consumption/(arterial O2 content-venous O2 content): Fick principle
If CO is decreased, then the difference between arterial O2 content and venous O2 content is increased +22019-06-26T18:26:16Z
cooldudeboy1crackles are heard bilaterally so there is pulm patho which leads to increased pulm vascular resistance, since systemic blood flows into the lungs.
any block in the flow ahead (lungs) will increase resistance in flow behind ( systemic )+2019-10-22T11:19:08Z
yb_26no, decreased CO => peripheral vasoconstriction => SVR will be increased+22019-07-02T19:43:46Z
yssya1992No SVR will increase due to RAAS and SAN thats why we decrease afterload in HF treatment ( ACEI, ARBs )+22019-07-10T08:32:35Z
snafullWouldn't pulmonary vascular resistance also be decreased here due to pulmonary vasodilation in the setting of an MI? +2019-07-19T19:29:34Z
cienfuegos@snafull: my initial thought is that we would see pulmonary vasoconstriction because of the relatively low oxygen tension (that results from the low cardiac output).+12019-07-24T02:22:01Z
