Influence of Mechanical Ventilation Mode on Arterial Pressure Variations- a Pilot Study

Not Applicable

Withdrawn

• Conditions: Hypovolemia; Blood Pressure; Critical Illness
• Interventions: Other: Ventilator mode change; Device: Monitoring of blood pressure variation

• Registration Number: NCT03246425
• Lead Sponsor: State University of New York - Upstate Medical University

Brief Summary

Mechanical ventilation has been known to produce changes in the flow of blood through the major blood vessels in the body. These changes may go undetected, but with continuous arterial blood pressure measurements, changes in the arterial waveform can be visualized. Although we know that these arterial pressure variations occur during mechanical ventilation, little is known about the effects of various modes of mechanical ventilation on these changes. The most common modes of ventilation used in ICU are Volume control, Pressure control and Airway pressure release ventilation.

Objective We have designed a prospective randomized pilot study to determine the effects of the commonly used ventilator modes on the arterial pressure.
