PNA resolution

How long does it take for lung POCUS signs of PNA to resolve? We will need to know this in the future if not all kids are getting XRs, and it may help us gauge response to treatment.  -Kids with positive lung POCUS in the ED get enrolled for serial POCUS over ?1mo, 3mo - ?how many scans total -Separate analysis for those with sub pleural consolidations vs those with larger consolidations -Enrollment would be much more successful if we went to them (i.e. - a second machine)
