Correlation Between Respiratory Variability of R-R Intervals and Systolic Pressure Variability

• Conditions: Heart Rate Determination

• Registration Number: NCT03267017
• Lead Sponsor: Rambam Health Care Campus

Brief Summary

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
