Regional Distribution of Ventilation to Assess Respiratory Muscle Dysfunction (DREM)

April 28, 2017 updated by: Lofaso, Centre d'Investigation Clinique et Technologique 805

Construction of a Database to Identify Early Indicators of Respiratory Muscle Dysfunction in Neuromuscular Patients From the Optoelectronic Plethysmography Assessment of the Thoracoabdominal Motion

The aim of this study is to better discriminate respiratory muscle dysfunction by comparing the measurements of thoracoabdominal motion obtained by an optoelectronic recording and the conventional tests of respiratory muscle strength. The final objective is to better select in the future the patients who need more specific assessment of diaphragmatic function like "maximal transdiaphragmatic pressure" measurement and "phrenic nerve stimulation".

Study Overview

Status

Unknown

Conditions

Detailed Description

All patients which had suspected respiratory muscle dysfunction will have usual exploration of the respiratory muscles according to the clinician prescription. These explorations can include :

  • Lung volumes in seating and supine position
  • Maximal inspiratory and expiratory pressures
  • Maximal sniff pressures

And when diaphragmatic dysfunction is suspected :

  • Maximal transdiaphragmatic pressure
  • Phrenic nerve conduction

These patients will also beneficiate to the determination of volume variations of the upper rib cage, the lower rib cage and the abdominal compartments by using Opto-electronic plethysmography.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
compartmental distribution of the inspired/expired volumes
Time Frame: 1 hour

Measurements of the thoraco-abdominal motion and of the global lung volume changes.

Measurements will be done during spontaneous breathing and during vital capacity maneuvers. Therefore the tidal volume, the inspiratory capacity and the expiratory reserve volume will be measured in liters and for each compartiment (upper thorax, lower thorax, abdomen) contribution of these volumes will be expressed in percentage.
1 hour

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
left side and right side contribution to the inspired/expired volumes
Time Frame: 1 hour
Measurements will be done during spontaneous breathing and during vital capacity maneuvers. Therefore the tidal volume, the inspiratory capacity and the expiratory reserve volume will be measured in liters and each side contribution of these volumes will be expressed in percentage.
