Study links excess oxygen during anesthesia to risk of organ injury

A Vanderbilt study found that higher levels of excess oxygen given to patients under general anesthesia add risk of injury to the kidneys, lungs and heart.

Vanderbilt study finds that the most common oxygen saturation targets for hospitalized patients appear equally safe and effective

A Vanderbilt study looked at the oxygen saturation target that results in optimal outcomes — number of days alive and free of mechanical ventilation — in 2,500 critically ill adults receiving mechanical ventilation.

Skin pigment affects oxygen monitor

Black patients in the ICU were more likely to have low or high blood oxygen levels than white patients, even when a pulse oximeter indicated 92-96% oxygen saturation, Vanderbilt researchers found.

Brain blood vessel response to hypoxia

The brain’s response to low oxygen — growth and remodeling of blood vessels — involves certain cell types and molecular pathways, Vanderbilt researchers have discovered.

Low oxygen could protect sick kidneys

Low oxygen – and the activation of factors that respond to this situation – may be protective in chronic kidney disease.
