13  Volume-control ventilation TIME VOLUME

14  Volume-control ventilation - SIMV TIME VOLUME

15  Pressure-control ventilation TIME PRESSURE

16 TIME PRESSURE 5cmH 2 O 10cmH 2 O

17 TIME PRESSURE 5cmH 2 O 15cmH 2 O Peak inspiratory pressure  Pressure = 10cmH 2 O PRESSURE SUPPORT SET : pressure support 10cmH 2 0 & PEEP 5cmH 2 O

18 TIME 10cmH 2 O 20cmH 2 O  Pressure = 10cmH 2 O PRESSURE SUPPORT SET : pressure support 10cmH 2 0 & PEEP 5cmH 2 O

19 TIME PRESSURE 5cmH 2 O 15cmH 2 O PRESSURE CONTROL SET : PIP 15cmH 2 0 & PEEP 5cmH 2 O  Pressure = 10cmH 2 O

20 TIME PRESSURE 5cmH 2 O 15cmH 2 O PRESSURE CONTROL SET : PIP 15cmH 2 0 & PEEP 10cmH 2 O  Pressure = 5cmH 2 O

21 TIME PRESSURE 5cmH 2 O 15cmH 2 O BiPAP SET : IPAP 15cmH 2 0 & EPAP 5cmH 2 O  Pressure = 10cmH 2 O

22 TIME PRESSURE 5cmH 2 O 15cmH 2 O BiPAP SET : IPAP 15cmH 2 0 & EPAP 10cmH 2 O  Pressure = 5cmH 2 O

24  Triggering  Inspiratory time  I:E ratios

25  Triggering  Flow or pressure change  Inspiratory time  I:E ratio

26  Triggering  Inspiratory time  Default 1.7 seconds  Often reduced (1.2 seconds more comfortable)  I:E ratio

27  Triggering  Inspiratory time  I:E ratio  Usually ~1:3  When adjusting inspiratory time check I:E ratio  Check not accidently ventilating with inspiratory time longer than expiratory time  Disease-specific

28  Oxygenation  FiO2  PEEP  Carbon dioxide  Respiratory rate  Pressure/volume
