Exposure to hypoxia for up to 3 h caused sustained hyperventilation during both wakefulness and sleep. Hyperventilation resulted from significant increases in minute ventilation due to increases in both tidal volume and frequency. Diaphragmatic activity changed significantly from augmenting activity with little postinspiratory-inspiratory activity (PIIA) in normoxia to augmenting activity with increased PIIA in hypoxia. The increase in PIIA was least in rapid eye movement sleep. These changes in diaphragmatic activity were associated with changes in airflow waveforms in inspiration and expiration. We conclude that the ventilatory response to hypoxia involves a change in the output of the central pattern generator and that the change is dependent in part on the state of consciousness. <\/jats:p>","DOI":"10.1152\/japplphysiol.01051.2002","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T20:46:02Z","timestamp":1425415562000},"page":"545-554","source":"Crossref","is-referenced-by-count":19,"title":["Ventilatory response of the cat to hypoxia in sleep and wakefulness"],"prefix":"10.1152","volume":"95","author":[{"given":"Andrew T.","family":"Lovering","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Witali L.","family":"Dunin-Barkowski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edward H.","family":"Vidruk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John M.","family":"Orem","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"24","reference":[{"key":"REF1","doi-asserted-by":"publisher","DOI":"10.1016\/0034-5687(88)90094-1"},{"key":"REF2","unstructured":"Berthon-Jones M and Sullivan CE.
