No results posted yet for this study

Summary

The investigators studied the predictive value of PPV in the patients with different influencing factors;and the method to improve the predictive value,which can improve the application of PPV in ICU.

Conditions

  • Haemodynamics
  • Fluid Responsiveness
  • Pulse Pressure Variation

Interventions

DEVICE

Patients were ventilated with assist-control ventilation（A/C） mode at different tidal volume

Ventilation mode was set to assist-control volume ventilation with different tidal volume, respiratory frequency 15 times/min, PEEP 5 centimeter water column.

BEHAVIORAL

spontaneous breathing and no spontaneous breathing

Data were recorded when patients had and did not have spontaneous breathing
