Table 1 Variation in EELV according to mouth closure and position

From: Proceedings of Réanimation 2020, the French Intensive Care Society International Congress

	0L/min	35L/min	70L/min
Supine	100
Open mouth		+ 1.2	− 0.6
Closed mouth		+ 12.5*	+ 18 *
Semi recumbent	+7
Open mouth		+ 2.1	− 3.8
Closed mouth		+ 9.3*	+ 25*^$

EELV values are expressed as percentages of variation of EELV measured in supine position with no flow
* p < .05 for comparison between open and closed mouth in same position with similar flow
^$p < 0.5 for comparison between 35L/min and 70L/min in same position
