(1)Department of Anaesthesia, University Hospital, Lund, Sweden. Deadspace is defined in terms of the efficiency of the lung in eliminating carbon dioxide. The airway deadspace is the volume of the airway in which gas moves chiefly by convection.The alveolar deadspace is caused by ventilation/perfusion inequalities at the alveolar level. The commonest causes of increased alveolar deadspace are airways disease--smoking, bronchitis, emphysema, and asthma.Other causes include pulmonary embolism, pulmonary hypotension, and ARDS.1)Department of Anaesthesia, University Hospital, Lund, Sweden.
