Fig. 2From: Biomedical engineer’s guide to the clinical aspects of intensive care mechanical ventilationA simple schematic diagram describing how MV is specified by selecting one option from each of three classes. Typically, the type (invasive vs non-invasive) is selected first, then the mode (support/spontaneous vs control), and finally the target (pressure vs volume). These three dimensions partition the possible combinations into six commonly employed sets (omitting non-invasive control ventilation)Back to article page
