Sustained pressure threshold
The sustained pressure threshold is calculated from the maximum
pressure (Pmax) setting. The sustained limit is calculated as follows:
.
Mechanical Ventilation with
PEEP Off:
For Pmax less than 30 cmH2O, the sustained pressure limit is 6 cmH2O.
For Pmax between 30 and 60 cmH2O, the sustained pressure limit is 20% of
Pmax.
For Pmax greater than 60 cmH2O, the sustained pressure limit is 12 cmH2O.
Mechanical Ventilation with
PEEP On:
For Pmax less than 30 cmH2O, the sustained pressure limit is 6 cmH2O plus “set
PEEP” minus 2 cmH2O.
For Pmax between 30 and 60 cmH2O, the sustained pressure limit is 20% of
Pmax plus “set PEEP” minus 2 cmH2O.
For Pmax greater than 60 cmH2O, the sustained pressure limit is 12 cmH2O plus
“set PEEP” minus 2 cmH2O.
Mechanical Ventilation Off:
For Pmax between 12 and 60 cmH2O, the sustained pressure limit is 50% of
Pmax.
For Pmax greater than 60 cmH2O, the sustained pressure limit is 30 cmH2O.
