Table 4 Color legend for encoding the rates of asynchrony events computed over 50 breathing cycles for a each pair (f b,P 0.1). Since self-triggered and backup cycles are not triggered by an inspiratory effort, there are all designated as “non-triggered” cycles

  1. SC = synchronous cycle, Tapr = cycle with an advanced pressure release, Tdpr = cycle with a delayed pressure release, Tsh = Tdpr or Tapr, DT = double-triggered cycles, NT = non-triggered cycle or self-triggered cycle or backup cycle
  2. Each color is allocated according to various thresholds on the rates of asynchrony events as reported in the table
