Spontaneous breathing during mechanical ventilation in ARDS

The objective of mechanical ventilation used in the management of Acute Respiratory Distress Syndrome (ARDS) is to ensure adequate tissue oxygenation and alveolar ventilation while limiting the patients’ work of breathing and preventing further damage to the lungs. Although the “partial support” ventilation modes were initially developed to assist weaning or liberation from supported ventilatio...

Does perfluorocarbon deoxygenate during partial liquid ventilation?

Perfluorocarbons accumulate in the dependent regions of the lungs, which may result in regional hypoxia if ventilation with oxygen is insufficient to oxygenate the dependent perfluorocarbon-filled alveoli. In this issue of Critical Care, Max et al present data that demonstrate a decrease in arterial oxygen tension (PaO2) at 30 min compared to that observed at 5 min after administration of FC 32...

Partial liquid ventilation.

Correspondence: B. Lachmann, Dept of Anesthesiology (Room Ee 2393), Erasmus University Rotterdam, Postbox 1738, 3000 DR Rotterdam, The Netherlands. There is strong indication that modes of ventilation that lead to repeated closure and opening of surfactantdeficient alveoli can induce severe functional and histological lung damage [1]. New modes of ventilation are directed at prevention of lung ...

Gas exchange during mechanical ventilation and spontaneous breathing. Intermittent mandatory ventilation after open heart surgery.

Pulmonary gas exchange rates in eight patients after open heart surgery were studied during weaning from the ventilator. We investigated continuous positive pressure ventilation (CPPV), intermittent mandatory ventilation (IMV) and spontaneous breathing with continuous positive airway pressure (CPAP). During each mode of ventilation we measured: CO2 production (VCO2), O2 consumption (VO2), cardi...
