What researchers measure

Primary outcomes

  1. lung sound score

    0: Normal aeration (N): presence of lung sliding with A lines or fewer than two isolated B lines 1. Moderate loss of lung aeration: multiple well-defined B lines (B1 lines) 2. Severe loss of lung aeration: multiple coalescent B lines (B2 lines) 3. Lung consolidation (C): the presence of a tissue pattern characterized by dynamic air

    Time frame: 30 minutes after arrival of postanesthetic care unit

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2019 (actual). Primary completion is estimated for Jan 2021, 22 months after the start.

Of 133 non-industry interventional studies with no phase under Pulmonary Atelectasis, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 25. This study's planned 22 months is above that.

Counting every sponsor, half of 135 studies reached it within 12 months; a quarter within 6 and three quarters within 25.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 7, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
