May guide deadspace assessment in anaesthetized patients with V/Q mismatch; leaves open need for prospective outcome trials.
This review provides an overview of the physiological concepts and clinical causes of deadspace during anesthesia.
R. Fletcher (1990) conducted a review in Deadspace during anaesthesia. Deadspace during anaesthesia is primarily caused by ventilation/perfusion inequalities due to airways disease, pulmonary embolism, ARDS, or right-to-left shunting.
