Differences in lung attenuation gradients between supine and standing positions in healthy participants on conventional/supine and upright computed tomography

Scientific Reports
The effect of gravity on the lungs has been evaluated using computed tomography (CT) in the supine and prone positions but not the standing position.

Evaluation of three-dimensional acromiohumeral distance in the standing position and comparison with its conventional measuring methods

Journal of Orthopaedic Surgery and Research, 2020
Background Narrowing of the acromiohumeral distance (AHD) implies a rotator cuff tear. However, conventional AHD measurements using two-dimensional (2D) imaging or with the patient in the supine position might differ from that while standing during daily

Prone positioning may increase lung overdistension in COVID-19-induced ARDS

Scientific Reports, 2022
Real-time effects of changing body position and positive end-expiratory pressure (PEEP) on regional lung overdistension and collapse in individual patients remain largely unknown and not timely monitored.

DISTRIBUTION OF VENTILATION IN THE SUPINE POSITION

British Journal of Anaesthesia, 1970
SUMMARY The relationship between lung volume and regional distribution of ventilation measured by the single breath oxygen test has been found to be similar in the upright and supine positions. When subjects breathe at progressively smaller lung volumes there is an increase in the slope of the alveolar plateau indicative of a redistribution of ...
