Evidence for manual hyperinflation

 · Manual hyperinflation has also been applied with a second aim: to open collapsed lung units not associated with airway secretion obstruction in surgical patients. 6 However, taking into account the accumulated evidence that lung hyperinflation causes only transitory alveolar recruitment (ie, for a matter of seconds) if it is not followed by sufficient PEEP, 7–9 it seems Cited by: 2. Manual hyperinflation is used to increase lung volumes and aid secretion clearance when used in conjunction with suctioning. Manual hyperinflation involves the use of a manual resuscitator bag (MRB) connected to oxygen to provide a slow, deep inspiratory breath followed by an inspiratory pause of seconds, and a rapid release of the resuscitation bag [2]. Inconsistencies in the indication and application of manual hyperinflation may have contributed to the association of manual hyperinflation with only short-term improvements in lung compliance, oxygenation, and secretion clearance but not on important clinical outcomes.1,12 SEE THE ORIGINAL STUDY ON PAGE Cited by: 2.

The studies were classified as having a level of evidence 2C and grade of recommendation C. Conclusions: Manual hyperinflation appeared useful for airway clearance in the investigated population, although the evidence available in the literature remains insufficient. Therefore, controlled randomized studies are needed to establish the safety and efficacy of manual hyperinflation in pediatric patients. The efficacy and consistency of manual hyperventilation is well supported in the literature, but there is limited published evidence supporting hyperventilation utilising a ventilator. Despite this, a recent survey established that almost 40% of Australian tertiary intensive care units utilise ventilator hyperinflation. • Manual hyperinflation is a frequently used maneuver that intends to mimic a forceful cough in critically ill intubated and mechanically ventilated patients. • Manual hyperinflation may improve pulmonary compliance, arterial oxygenation, and clearance of airway secretions.

15 апр. г. The evidence base had a number of problems, but the authors' conclusions are appropriately cautious and seem reasonable. Database of Abstracts. These studies demonstrate that expiratory flow rates during manual hyperinflation are consistently slower than that of cough. Evidence does exist, however. 30 июл. г. of mucolytics and/or bronchodilators, manual hyperinflation and use of is a remarkable lack of evidence for clinical benefit [10,12–14].
