Correlation Between Respiratory Variability of R-R Intervals and Systolic Pressure Variability
Correlation Between Respiratory Variability of R-R Intervals and Systolic Pressure Variability
This prospective study is designed to assess and quantify the correlation between respiratory
 changes in R-R interval and the respiratory changed in invasive systolic blood pressure in
 ventilated patients during changes in posture and peak end expiratory pressure (PEEP) and
 following a fluid bolus
Inclusion Criteria:

 -  Age 18-80

 -  Scheduled for surgery under general anesthesia requiring invasive blood pressure
 monitoring

 Exclusion Criteria:

 -  Heart Rate other than sinus

 -  Cardiac Pacemaker Status

 -  Transplanted Heart
