Determination of oxygen saturation compared to a prescribed target range using continuous pulse oximetry in acutely unwell medical patients.

Background: Both inadequate and excessive administration of oxygen to acutely unwell patients results in risk of harm. Guidelines recommend titration of oxygen to achieve a target oxygen saturation (SpO) range. Information regarding whether this is being achieved is limited.

Closed-Loop Oxygen Control Using a Novel Nasal High-Flow Device: A Randomized Crossover Trial.

Background: Oxygen administration is recommended for patients with hypoxemia to achieve a target [Formula: see text] range. Strategies to achieve this in clinical practice are suboptimal. We investigated automatic oxygen titration using a novel nasal high-flow device with closed-loop oxygen control.
