Carbon dioxide rebreathing with the anaesthetic conserving device, AnaConDa®.
BACKGROUND The anaesthetic conserving device (ACD) AnaConDa(®) was developed to allow the reduced use of inhaled agents by conserving exhaled agent and allowing rebreathing. Elevated has been observed in patients when using this ACD, despite tidal volume compensation for the larger apparatus dead space. The aim of the present study was to determine whether CO(2), like inhaled anaesthetics, adso...
متن کاملHealth worker exposure risk during inhalation sedation with sevoflurane using the (AnaConDa®) anaesthetic conserving device.
INTRODUCTION AND OBJECTIVE Occupational exposure to sevoflurane should not exceed 2 ppm. During inhalation sedation with sevoflurane using the anaesthetic conserving device (AnaConDa(®)) in the post-anaesthesia care unit, waste gases can be reduced by gas extraction systems or scavenging devices such as CONTRAfluran™. However, the efficacy of these methods has not been clearly established. To d...
متن کاملThe effects of apparatus dead space on P(aCO2) in patients receiving lung-protective ventilation.
BACKGROUND Lung-protective ventilation using tidal volume (V(T)) of 4-6 mL/kg (predicted body weight) reduces mortality (compared with traditional V(T)) in patients with acute respiratory distress syndrome and acute lung injury. Standardized use of lower V(T) can result in respiratory acidosis and has raised new concerns about the appropriate configuration of the ventilator circuit, especially ...
متن کاملDead space: the physiology of wasted ventilation.
An elevated physiological dead space, calculated from measurements of arterial CO2 and mixed expired CO2, has proven to be a useful clinical marker of prognosis both for patients with acute respiratory distress syndrome and for patients with severe heart failure. Although a frequently cited explanation for an elevated dead space measurement has been the development of alveolar regions receiving...
متن کاملProtective strategies for one-lung ventilation
provided the original work is properly cited. CC Hypoxemia and acute lung injury (ALI) are major concerns with one-lung ventilation (OLV) during thoracic surgery. Hypoxemia is usually the result of alveolar hypoventilation and an increasing shunt fraction, whereas ALI is caused by ventilatory stress (volutrauma, atelectrauma, and barotrauma), reexpansion pulmonary injury, and the lung surgery i...
