Table 3.

Feasibility

	Mid-clavicular	Mid-axillary	p value
Right hemidiaphragm	90% (0.55–0.99)	100% (0.69–1)	0.61
Left hemidiaphragm	20% (0.03–0.56)	100% (0.69–1)	> 0.001

The table shows distribution of useable ultrasound images from the different views. Visualization of the right/left mid-clavicular line is required to do M-mode measurement of the right/left hemidiaphragm. Likewise, visualization of the right/left mid-axillary line was required to do B-mode and Area measurements of the right/left hemidiaphragm. Numbers are given in percentages and 95% CI
