Outcome Measures

Primary Outcomes (1)

  • CALSA

    The primary objective of this study is to compare CALSA with FRI. The respiratory sounds recordings are performed with a digital stethoscope and connected to the sound card of a laptop with commercial software, suitable for data acquisition. The respiratory sounds recordings are conducted in accordance with the Computerized Respiratory Sound Analysis guidelines (CORSA) for short-term acquisition. Subjects are asked to breathe through the mouth in a sitting position (tidal breathing) during the recordings. Three sets of recordings are made for 7 - 10 respiratory cycles with a maximum duration of 25 seconds.

    1 day

Secondary Outcomes (4)

  • Total Airway Volume (iVaw)

    1 day

  • Total Airway Resistance (iRaw)

    1 day

  • Internal Airway Distribution

  • Lobar Volume

    1 day
