This phenotype returns the median value for positive end expiratory pressure (PEEP) using actual or measured values mapped to MPOG concept 3210 Positive End Expiratory Pressure- Measured. Only values captured between case start and case end are included in determining the median value. Case start and end are determined by the following algorithm:
- Case Start
- Patient In Room. If not available, then
- Induction End. If not available, then
- Anesthesia Start
- Case End
- Patient out of room. If not available, then
- Anesthesia End
The PEEPActual phenotype is used to determine the list of starting PEEP values. The median PEEP is then determined from the resulted list.
