Calculator: Systemic vascular resistance in adults


Calculator: Systemic vascular resistance in adults

 
Input
 
Mean aortic pressure  
Right atrial pressure  
Systemic flow  

 
Result
 
Important: Inputs must be complete to perform calculation.

 
 
SVR   dynes-sec-cm-5
 

 
 

 
Notes
  • In most cases, Systemic flow is equivalent to the cardiac output.
  • Normal SVR is approximately 1170 plus or minus 270 dynes-sec-cm-5.
  • In most cases, the Mean aortic pressure is equivalent to the mean arterial pressure, which can be obtained from most hemodynamic monitors.
  • For information on the use of the SVR, please see UpToDate topic reviews on the use of vasopressors and inotropes and on intraoperative transesophageal echocardiography.
  • SVR: systemic vascular resistance.

 
Equations used
 
SVR = 80 * ( Mean_aortic_pressure - Right_atrial_pressure) / Systemic_flow

 

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
