1. BASIC PRINCIPLES OF MECHANICAL VENTILATION ANDVENTILATOR GRAPHICS

19. Types of Waveforms Volume Modes Pressure Modes Volume Control/ SIMV (Vol. Control) Pressure Control/ PRVC SIMV (PRVC) SIMV (Press. Control) Pressure Support/ Volume Support Pressure Flow Volume Pressure Flow Volume

27. Volume/Time Scalar Inspiratory Tidal Volume Exhaled volume returns to baseline

31. Flow/Time Scalar Volume Pressure

37. Pressure/Volume Loops 15 30 5 250 500

43. Pressure/Volume Loops 15 30 5 250 500 15 30 5 Increased Compliance Decreased Compliance Example: Emphysema, Surfactant Therapy Example: ARDS, CHF, Atelectasis 500 250

47. Flow/Volume Loops 0 200 400 600 20 40 60 -20 -40 -60

50. Flow/Volume Loops 0 200 400 600 20 40 60 -20 -40 -60 PEF Start of Inspiration Start of Expiration

61. Asynchrony F/V Loop P/V Loop

62. Rise Time & Inspiratory Cycle Off %
