Table 1 Studies comparing manual hyperinflation (MH) with standard care
Author [ref] | Year | Subjects | N | Study design | Intervention | Reported aspects of the MH maneuver | Main results |
|---|---|---|---|---|---|---|---|
Hodgson et al. [26] | 2000 | Unselected intensive care unit patients | 18 | Randomized crossover trial | MH + endotracheal suction vs. standard care | Volume: - Inspiration speed: - Pause: + Expiration speed: ± | MH increased pulmonary compliance but did not affect P/F; MH increased clearance of airway secretions |
Patman et al. [22] | 2000 | Postcardiac surgery patients | 94 | Randomized controlled trial | MH + endotracheal suction vs. standard care | Volume: - Inspiration speed: - Pause: + Expiration speed: - | MH increased pulmonary compliance and P/F |
Barker et al. [20] | 2002 | Patients with acute lung injury | 17 | Randomized controlled trial | MH + endotracheal suction + position changes of patient vs. position changes only | Volume: + Inspiration speed: - Pause : + Expiration speed: - | MH affected neither pulmonary compliance nor P/F |
Choi et al. [25] | 2005 | Patients with pneumonia | 15 | Randomized crossover trial | MH + endotracheal suction vs. standard care | Volume: ± Inspiration speed: - Pause: + Expiration speed: + | MH improved pulmonary compliance |
Maa et al. [5] | 2006 | Patients with atelectasis | 23 | Randomized controlled trial | MH + endotracheal suction vs. standard care | Volume: - Inspiration speed: + Pause: + Expiration speed: ± | MH affected neither P/F nor clearance of airway secretions |
Blattner et al. [21] | 2008 | Postcardiac surgery patients | 55 | Randomized controlled trial | MH + endotracheal suction vs. standard care | Volume: - Inspiration speed: - Pause: ± Expiration speed: - | MH improved pulmonary compliance and PaO2 and reduced duration of MV |
Patman et al. [23] | 2009 | Brain-injury patients | 144 | Randomized controlled trial | MH + endotracheal suction and side lying vs. standard care | Volume: ± Inspiration speed: ± Pause: + Expiration speed: ± | MH affected neither duration of MV and length of stay in intensive care unit, nor the incidence of pneumonia |
Paulus et al. [24] | 2011 | Postcardiac surgery patients | 100 | Randomized controlled trial | MH + endotracheal suction vs. standard care | Volume: + Inspiration speed: + Pause: + Expiration speed: + | MH did not affect pulse-oximeter oxygen saturation |
