Surface Mechanomyography Using a Parasternal Patch to Measure and Detect Respiratory Drive and Effort

Surface mechanomyography (sMMG) has been proposed as a tool to study muscle mechanical activity. sMMG is a noninvasive technique using specific transducers to record muscle surface oscillations due to mechanical activity of the motor units . It could be of major interest for the detection of respiratory efforts in patients with respiratory failure. This study aims at assessing the performances of sMMG to measure and detect respiratory drive and effort in healthy volunteers.

Primary outcomes

  1. Accuracy of sMMG to detect respiratory effort

    Time frame: 5 minutes after the beginning of recording

    Delays between the beginning of the respiratory effort detected by sMMG and Eadi and the end of the respiratory effort detected by sMMG and Eadi (msec)

Secondary outcomes

  1. Comparison between sMMG-time (MMG-TP) and PTPes-Pes Peak

    Time frame: 5 minutes after the beginning of recording

    Accuracy of sMMG to assess the intensity of respiratory effort (in comparison with pressure-time product in cm H2O.s.min-1)

  2. Comparison between sMMG slope & Eadi parameters

    Time frame: 5 minutes after the beginning of recording

    Accuracy of sMMG to assess the intensity of respiratory drive (in comparison with Eadi in microvolt)

  3. Comparison between sMMG slope & slope Peso

    Time frame: 5 minutes after the beginning of recording

    Accuracy of sMMG to assess the intensity of respiratory drive (in comparison Peso in cm H20)

  4. Delay between neural time measured by sMMG and neural time measured by Eadi

    Time frame: 5 minutes after the beginning of recording

    Accuracy of sMMG to assess the duration of inspiratory neural time (in comparison with Eadi in msec)
