1 This tracing depicts 30 seconds of information.
This tracing depicts 30 seconds of information. Careful review of the waveforms reveals 2 types of breaths. One type of breath (arrow A) has the same peak flow, flow waveform (decelerating), and tidal volume, but different peak inspiratory pressures. This indicates volume-control mandatory breaths. The second type shows consistent (lower) peak airway pressures but different volumes and flows, indicating these breaths are pressure-targeted breaths. Furthermore, these breaths have random start times and variable inspiratory times, indicating that they are patient-triggered and patient-cycled and are thus spontaneous breaths. They are in fact pressure-support breaths. Therefore, we conclude that the mode is volume-control intermittent mandatory ventilation with pressure support. The PEEP is 5 cm H2O.
