- Supplementary figure 1 - Stepwise decrease in plethysmographic box pressure as a vacuum source is applied, displaying that the box is airtight when required for measurement of thoracic gas volume (A), a representative thoracic gas volume trace showing negligible thermal drift during measurement (B) and the relationship between plethysmographic box pressure and tracheal pressure for the TGV trace shown above indicating strong correlation between these two measurements.
