BACKGROUND Although evaluation of cardiac output by the partial carbon dioxide rebreathing technique is as accurate as thermodilution techniques under controlled mechanical ventilation, it is less accurate at low tidal volume. It is not clear whether reduced accuracy is due to low tidal volume or low minute ventilation. The effect of spontaneous breathing on the accuracy of partial carbon dioxi...

INTRODUCTION There are several ventilator modes that are used for maintenance mechanical ventilation but no conclusive evidence that one mode of ventilation is better than another. Vibration response imaging is a novel bedside imaging technique that displays vibration energy of lung sounds generated during the respiratory cycle as a real-time structural and functional image of the respiration p...

During mechanical ventilation for acute respiratory distress syndrome, tidal volume (VT) must be reduced. Once switched to pressure-support ventilation, there is a risk that uncontrolled large VT may be delivered. A 63-year-old man with community-acquired pneumonia required tracheal intubation and mechanical ventilation, with a VT of 6 mL/kg predicted body weight, PEEP of 10 cm H2O, a respirato...
