Alveolar Dead Space as Predictor of Multi-organ Failure and Mortality in Medical Intensive Care Patients With Sepsis Requiring Mechanical Ventilation
The University of Texas Health Science Center, Houston
Summary
This is an observational study to understand the changes in alveolar dead space in medical critically ill patients with severe infection (severe sepsis) requiring mechanical ventilation and the possibility to predict multi-organ failure. The measurement of alveolar dead space used to require sophisticated equipment and time. New ventilators have microprocessors that allow rapid mathematical calculation with minimal intervention.
Description
The patient will be followed during their ICU stay up to two weeks while on mechanical ventilation. Patient will be followed daily for the initial 48 hours and then once per week for 2 weeks while mechanically ventilated.
