Effect of Mueller manoeuvres (−20 cm H2O and −40 cm H2O) on POBF relative to baseline measurements
| Subject | Mueller manoeuvre −20 cm H2O | Mueller manoeuvre −40 cm H2O | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Inspiratory effort | Change in POBF relative to baseline | Inspiratory effort | Change in POBF relative to baseline | |||||||
| Duration (seconds) | Mean P (cm H2O) | M2A (% (SD)) | M2B (% (SD)) | p value | Duration (seconds) | Mean P (cm H2O) | M4A (% (SD)) | M4B (% (SD)) | p value | |
| Analyses include repeated ANOVA and Student-Newman Keuls post hoc tests for each subject separately, and for the group as a whole. Only significant p values are shown. | ||||||||||
