Figure 3c:

Graphs show mean change in vital signs after xenon dose administration relative to baseline as a function of time. Data were acquired after inhaling the xenon dose and were averaged over all doses for a given time point (four doses for healthy volunteers, three doses for age-matched control subjects and subjects with COPD) but are separated by subject group. Dashed vertical lines = time after which subjects were permitted to move about freely. Graphs show (a) systolic blood pressure (BP), (b) diastolic blood pressure, (c) blood oxygen saturation (Spo₂), (d) heart rate, and (e) respiratory rate. No clinically important changes in any of these vital signs were noted for any of the groups.
