  • OBJECTIVE: The aim of the study was to test the applicability of Ventrak 1550/Capnogard 1265 (V-C) for respiratory dead space (VD) measurement and to determine anatomic (VDana), physiologic (VDphys), and alveolar dead spaces (VDalv) in ventilated neonates. (biomedsearch.com)
  • Each breath ( tidal volume ) is composed of functional movement of air in and out of the alveolus and nonfunctional movement of air through bronchioles, bronchi, trachea, and nonperfused areas of lung ( physiologic dead space ). (mhmedical.com)
  • The physiologic dead space is approximately 30% of the tidal volume. (mhmedical.com)
