Acute effects of esketamine on hypoxic ventilatory response, haemodynamics, and brain function in healthy volunteers

The acute hypoxic ventilatory response is a critical chemoreflex originating at the carotid bodies. This study investigates the impact of low-dose i.v. esketamine on the ventilatory response to 20 min of isocapnic hypoxia to test the hypothesis that esketamine does not affect hypoxic ventilation.
