Article Figures & Data
Figures
- Fig. 1.
Pyramid of skills required to master ventilator technology. The terms in green are from Bloom's revised taxonomy of learning objectives.
- Fig. 2.
Building blocks for constructing a mode. CMV = continuous mandatory ventilation; IMV = intermittent mandatory ventilation; CSV = continuous spontaneous ventilation.
- Fig. 3.
A breath is defined in terms of the flow-time curve. Important timing parameters related to ventilator settings are labeled.
- Fig. 4.
Trigger and synchronization windows. If a patient signal occurs within the trigger window, inspiration is patient-triggered. If a patient signal occurs within a synchronization window, inspiration is ventilator-triggered (or cycled if at the end of inspiration) and patient-synchronized. Note that, in general, a trigger window is used with continuous mandatory ventilation, a synchronization window is used with intermittent mandatory ventilation.

- Fig. 6.
Rubric for determining the control variable of a mode. Paw = airway pressure, SIMV = synchronized intermittent mandatory ventilation; VT = tidal volume; P = pressure; E = elastance; V = volume; R = resistance; V̇ = inspiratory flow. Courtesy Mandu Press.

Venn diagram illustrating how the mode taxonomy can be viewed in terms of discriminating features and defining features. VC = volume control; PC = pressure control; CMV = continuous mandatory ventilation; IMV = intermittent mandatory ventilation; CSV = continuous spontaneous ventilation; PETCO2 = end-tidal partial pressure of carbon dioxide; a = adaptive targeting; s= set-point targeting.
