Effects of manual hyperinflation

 · Patients receiving invasive mechanical ventilation who are unable to breathe spontaneously or produce an effective cough may retain pulmonary secretions leading to bronchial obstruction and atelectasis with the attendant adverse effects. 1,2 To enhance airway clearance, a maneuver known as manual hyperinflation, which involves lung ventilation with Cited by: 2. Manual Hyperventilation = rapid breaths delivering FiO2 at or greater than TV to reverse hypoxaemia and improve oxygenations e.g. during a sudden desaturation. Manual Hyperinflation = slow, deep breaths at greater than TV used to increase lung volume. The effects of manual hyperinflation, with respect to excess bronchial secretions and static lung compliance, have been well-established. There is, however, only limited evidence as to the efficacy of ventilator hyperinflation as a physiotherapy treatment technique. The purpose of the present study was to compare the effects of manual hyperinflation and ventilator Cited by:

Ventilator hyperinflation (VHI) and manual hyperinflation (MHI) are thought to improve secretion clearance, atelectasis and oxygenation in adults receiving mechanical ventilation. However, to the authors' knowledge, a systematic review of their relative effectiveness has not been undertaken previously. Manual lung hyperinflation treatment also cleared a significantly greater wet weight of sputum (P=). There were no differences between manual lung hyperinflation and side-lying treatment for gas exchange (P a o 2 /F I O 2 and P a co 2), mean arterial pressure or heart rate. In conclusion, total static respiratory system compliance and. Introduction Manual hyperinflation (MH), a maneuver applied in mechanically ventilated patients to facilitate secretion removal, has large variation in its performance. Effectiveness of MH is usually evaluated by its capacity to generate an expiratory flow bias. The aim of this study was to compare the effects of MH—and its resulting flow bias—applied according to clinical practice versus.

Hemodynamic Effects of Manual Hyperinflation in Critically Ill Patients (Singer et at) This is especially pertinent when even the target of. a 50% increase in tidal volume is not reached, as was. seen in half of our studies and, as three instances. Manual hyperinflation not only increases the tidal volume but the quick release of the. Abstract. Introduction: Manual hyperinflation (MH), a maneuver applied in mechanically ventilated patients to facilitate secretion removal, has large variation in its performance. Effectiveness of MH is usually evaluated by its capacity to generate an expiratory flow bias. The aim of this study was to compare the effects of MH-and its resulting flow bias-applied according to clinical practice versus according to expert recommendation on mucus movement in a lung model simulating a.
