Hypoxia increased the frequency and duration of MVTs, as identified by artefact (loss of respiratory waveform). A, during the initial minute of hypoxia, MVTs were generally intermittent and self-limiting. B, towards the hypoxic nadir, they tended to become more frequent and repetitive, signalling a shift away from deeper-stage QS; periods between repetitive MVTs were scored as indeterminate (IN).
