Mechanical Breath Work

Total work (van der Staay, et al)

Peak Inspiratory Pressure (PIP)
cmH2O
Tidal Volume (VT)
Lit

Equation: Total work = Peak inspiratory pressure (PIP) X Tidal volume (VT)

Reference: Advanced modes of mechanical ventilation and optimal targeting schemes

Total work (van der Staay, et al)

PEEP
cmH2O
Tidal Volume (VT)
Lit

Equation: PEEP work = PEEP X Tidal volume (VT)

Reference: Advanced modes of mechanical ventilation and optimal targeting schemes

Tidal work (van der Staay, et al)

Peak Inspiratory Pressure
PEEP
cmH2O
Tidal Volume (VT)
Lit

Equation: Tidal work = ½ VT X Tidal pressure (PIP – PEEPTotal)

Reference: Advanced modes of mechanical ventilation and optimal targeting schemes

Elastic work (van der Staay, et al)

Elastic work = PEEP work + Tidal work

Resistive work (van der Staay, et al)

Resistive work = Total work – Elastic work

Inspiratory work (van der Staay, et al)

Inspiratory work = Tidal work + Resistive work
