Summary

The Rapid Shallow Breathing Index (RSBI) is the ratio between respiratory rate (RR) and tidal volume (VT). It is routinely used to predict mechanical ventilation weaning outcome in ICU patients. However RSBI doesn't reflect the muscular contribution of diaphragm or accessory muscles in generating tidal volume. Actually, diaphragmatic dysfunction can even delay weaning process, because accessory muscles are more fatigable than the diaphragm.

Hence, the investigators hypothesized that diaphragmatic displacement (DD) could be associated with RSBI in a new index named Rapid Shallow Diaphragmatic Index (RSDI) such as: RSDI = RSBI/DD.

The aim of this study is to compare the ability of the RSDI versus the traditional RSBI to predict weaning success in ready-to-wean patients.

Conditions

  • Mechanical Ventilation
  • Mechanical Ventilator Weaning
  • Extubation
  • Diaphragm Ultrasound

Interventions

DIAGNOSTIC_TEST

assess diaphragmatic displacement (DD) using ultrasonography

During a spontaneous breathing trial (SBT) we will simultaneously, for all included patient, assess diaphragmatic displacement (DD) using ultrasonography, respiratory rate (RR) and tidal volume (VT) on ventilator screen.
