Dissipated energy inside the respiratory system during mechanical ventilation

Dissipated energy during protective mechanical ventilation

Introduction From literature we know that a cornerstone of the protective lung ventilation in Acute Respiratory Distress Syndrome (ARDS) patients [1] and during general anesthesia [2] is a low tidal volume. On the other hand, driving pressure seems to be the variable that best stratifies mortality risk [3]. Our hypothesis is that the combination of volume and pressure, that is the energy dissip...

Advances in respiratory monitoring during mechanical ventilation.

This review provides an update on the various techniques that are available to monitor patients during mechanical ventilation with an emphasis on clinical observations and applications in critically ill patients.

Practice variation in respiratory therapy documentation during mechanical ventilation.

STUDY OBJECTIVES Implementation of new ventilatory strategies such as lung-protective ventilation for ARDS will require a multidisciplinary approach with considerable physician and respiratory therapy (RT) interaction. One of the key factors in this communication is complete and accurate RT documentation of ventilator settings. Few studies have explored the quality and variability of this docum...

Does nonchemical inhibition of respiratory output occur during mechanical ventilation?

Respiratory phase locking during mechanical ventilation in anesthetized human subjects.

The coupling patterns between the rhythm of a mechanical ventilator and the rhythm of spontaneous breathing were studied in enflurane-anesthetized adult human subjects. The spontaneous breathing pattern was altered in response to different frequencies and amplitudes of forced lung inflations. A 1:1 phase locking (the frequency of the mechanical ventilator is matched by the frequency of spontane...
