Effects of manual hyperinflation and suctioning in respiratory mechanics

Manual hyperinflation is used to increase lung volumes and aid secretion clearance when used in conjunction with suctioning[1]. 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 #91;2#93;.  · Effects of manual hyperinflation and suctioning in respiratory mechanics in mechanically ventilated patients with ventilator-associated pneumonia.

Subject objective: To assess the hemodynamic effects of manual lung hyperinflation in mechanically ventilated patients and to measure the different inspiratory pressures and tidal volumes generated by different operators. Design: Measurements of aortic blood flow (by esophageal Doppler ultrasonography), systemic blood pressure, tidal volumes (by respirometry), and inspiratory pressures in the. likelihood of side effects, reduce the ratio i.e MHI breaths to TV breaths. This depends greatly on the patient tolerance the indication for MHI to be used. o Stop if adverse effects continue to occur or the patient requests/ appears distressed. o Suction if palpable fremitus is felt or heard in the bag. Background: In developing countries, lower respiratory tract infection is a major cause of death in children, with severely ill patients being admitted to the critical-care unit. While physical therapists commonly use the manual hyperinflation (MHI) technique for secretion mass clearance in critical-care patients, its efficacy has not been determined in pediatric patients.

Manual hyperinflation may improve pulmonary compliance, arterial oxygenation, and clearance of airway secretions. As such, manual hyperinflation may benefit intubated and mechanically ventilated critically ill patients. Manual hyperinflation plus suction, but not after suction alone. Conclusion: This study suggests that manual hyperinflation in conjunction with suction induces beneficial changes in respiratory mechanics in mechanically ventilated patients with ventilator-associated pneumonia. These improved respiratory mechanics suggest manual hyperinflation plus suction may be an effective intervention to improve the lung function of patients with ventilator- associated pneumonia. The effect of manual hyperinflation plus suction on prevention and treatment of ventilator- associated pneumonia requires further investigation.
