response to exercise = increased stroke volume = increased pulse pressure (Sys - Dia)BP
Qp/Qs is the ratio of Fick principle calculations for pulmonary flow and systemic flow.
Qp = VO2/(PVO2 - PAO2)
Qs = VO2/(CaO2 - CvO2)
when algebra is done and sats are used instead of content
Qp/Qs = (AoSat - MVSat)/(PVsat - PAsat)
Coarctation of the Aorta
Pulses are difference between systolic and diastolic. with collateral flow through parallel circuits; e.g., intercostal arteries, MAP can be normal but pulses are weak.
