PURPOSE OF REVIEW: The purpose of the review is to alert clinicians to the prevalent and frequently underrecognized problem of asynchrony in mechanically ventilated patients. To provide a mechanistic model of patient-ventilator asynchrony to help personnel understand how different asynchronies develop. To provide practical advice on how to recognize and solve different asynchronies in different contexts. RECENT FINDINGS: Patient-ventilator asynchrony is a serious problem that is associated with prolonged mechanical ventilation, prolonged ICU and hospital stays, and increased mortality...

Assisted/supported modes of mechanical ventilation offer significant advantages over controlled modes in terms of ventilator muscle function/recovery and patient comfort (and sedation needs). However, assisted/supported breaths must interact with patient demands during all three phases of breath delivery: trigger, target, and cycle. Synchronous interactions match ventilator support with patient demands; dyssynchronous interactions do not. Dyssynchrony imposes high pressure loads on ventilator muscles, promoting muscle overload/fatigue and increasing sedation needs...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
