Do respiratory manoeuvres (voluntary deep breaths, lower thoracic expansion exercises, or incentive spirometry) improve transcutaneous oxygen and carbon dioxide tensions in stable post-operative CABG patients?

May support incentive spirometry for acute oxygenation post-CABG; hypothesis-generating and should not yet change practice.
Do respiratory manoeuvres (voluntary deep breaths, lower thoracic expansion exercises, or incentive spirometry) improve transcutaneous oxygen and carbon dioxide tensions in stable post-operative CABG patients?
Incentive spirometry produces a significantly greater acute increase in transcutaneous oxygen tension compared to voluntary deep breaths or lower thoracic expansion exercises in post-CABG patients.
Jenkins et al. (1988) studied this question.
