No results posted yet for this study

Summary

The main objective of this study is to determine a threshold value of diaphragmatic excursion (ultrasound measures: expiration versus inspiration)that best predicts a 50% collapsibility of the inferior vena cava.

Conditions

  • Collapsibility of the Inferior Vena Cava

Interventions

PROCEDURE

Ultrasounds with controlled breathing

The patient will have cardiac, abdominal and thoracic ultrasounds with controlled and monitored inspiratory effort. This gesture takes about 40 minutes.
