Respiration, Artificial
The Correlational Study of PPV in Various VT in Mechanically Ventilated Patients
Mesquida, J et al showed there was a significant linear correlation between pulse pressure variations under tidal volume 6 ml/kg and 8 ml/kg in patients after the resuscitation phase of severe sepsis and septic shock.
- Trial name
- NCT01950949
- Testing
- 300 ml Hydroxyethyl Starch 130/0.4 and Sodium Chloride Injection infusing in 15 minutes if PPV under VT 8 ml/kg was larger than 13% in the initial investigation
