Measuring the hypoxic ventilatory response.
The example experimental results presented show how the steady state ventilatory response to hypoxia may be measured using a sequential gas delivery circuit and prospective targeting of end-tidal PCO(2) and PO(2). They also demonstrate how 3 steady state isocapnic ventilatory responses to hypoxia provide hypoxic and hyperoxic ventilatory responses to CO(2) that can be compared between individuals and between different physiological and environmental conditions as well as to modified rebreathing responses.
