The results are in!   There were multiple correct responses.  The patient indeed has high resistance as shown by the large difference between peak-inspiratory pressure (PIP) and plateau pressure (Pplat).  They also have significant expiratory flow limitation as suggested by the shape of the expiratory flow-time curve (methods for assessing EFL will be included in another…

Since its completion, the LUNG SAFE database has been utilized to answer a wide range of clinical questions regarding global practice. With the help of one of the authors, Dr. Tài Pham, we have provide a list, with brief synopsis of the currently published research, as well as upcoming future/planned analyses.
