A patient is agitated during mechanical ventilation and interventions are made to achieve better patient-ventilator synchrony. Flow and pressure curves from before and after the intervention are shown.
Based on the change, which of the following best describes the intervention?
- Matching intrinsic PEEP with Extrinsic PEEP to facilitate triggering each breath
- Increasing flow rate and respiratory rate to accommodate increased respiratory drive
- Switching mode to pressure support
- Switching mode to APRV
- Paralysis
Explain what you expect to see in each of the above scenarios.
5. paralyzed, I think…
– the peep did not change
– I time did not shorten
– this is not the pressure time profile of APRV
– PSV is driven by patient. Flow is too uniform
– loss of trigger
