CaO2- (Hbx1.34)(SaO2)+(PaO2x0.003), CvO2- (Hbx1.34)(SvO2)+(PvO2x0.003), C(a-v)O2- CaO2-CvO2, C.O.- HRxSV or VO2/C(a-v)O2 x 10, EF- SV/EDV.
Discuss LVSWI?
directly related to SVR, mycardial mass, viscosity.
Discuss Ejection Fraction?
fraction of end diastolic volume ejected with each beat. EF=SV/EDV. <30% exercise tolerance severly limited.
Discuss ESV?
End Systolic Volume- amount of blood after the contraction. Afterload or diastole.
Identifying marks for an arterial wave form?
the vertical scale has higher numbers
Estimated C.O. monitoring?
central venous blood used. If C(a-v)O2 is up then C.I. will be down and vice versa. Keep sats above 95%.
Discuss SVR?
Systemic Vascular Resistance- pressure on the vessel's throughout the body (from aorta).
Discuss Cardiac Work?
energy the heart uses to eject blood against the aortic or pulmonary pressures. Correlates with O2 requirments of heart. L ventricle has to work 6X harder then the R.
