cardiac index normal value
2.5-4 L/min/m2
systemic vascular resistance normal value
700 - 1600 dynes/sec/cm-5
pulmonary capillary wedge pressure normal value
4-12 mmHg
Pulmonary Vascular Resistance (PVR)
20-130 dynes/s/cm-5
central venous pressure normal value
5-9
pulmonary artery pressure normal value
25/10 (+/- 5)

70-80
MAP =
CO x SVR
CI =
CO/BSA
where does cardiac output go?
,renal = 25%
brain = 15%
heart = 5%
what is cardiac performance determined by (x4)
preload
afterload
contractility
HR
preload
-linearly related to left ventricular end-diastolic pressure and filling pressure
- wedge pressure measures preload
afterload
resistance against the ventricle contracting (SVR)
contractility
the force of contraction
stroke volume
- determined by LVEDV, contractility and afterload
, - LVEDV - LVESV
ejection fraction
stroke volume/LVEDV
EDV (end-diastolic volume)
-determined by preload and distensibility of the ventricle
ESV (end-systolic volume)
- determined by contractility and afterload
cardiac output increased with HR up to ___ but then starts to decrease because ___
- 120-150
- decreased diastolic filling time
How much LVEDV is accounted for by atrial kick
20%
