“…They used a self-inflating Laerdal (Laerdal Medical, Norway) resuscitation bag and found no significant improvements in oxygenation. The studies 3,4 in which oxygenation showed improvement used a Mapleson circuit (Mapleson "C" circuit and a 2 L reservoir bag [BS 3352, Warne Surgical Products Ltd, Lurgan, Ireland]. In the present study, although a self-inflating Intersurgical resuscitation bag (Intersurgical Ltd, Berkshire, UK) was used, significant improvements in oxygenation were found after MHI, which persisted significantly above baseline at 20 minutes after hyperinflation.…”

“…2 Manual hyperinflation (MHI) is known to improve pulmonary compliance and oxygenation (PaO 2 : FIO 2 ). 3,4 Ventilator hyperinflation (VHI), on the other hand, is a newer technique and comparatively less popular than MHI. Yet, few studies comparing MHI and VHI have found VHI to be an equally beneficial 5 alternative of MHI or even a better alternative than MHI.…”

“…It has been shown that the use of respiratory physiotherapy techniques can reduce pulmonary secretion retention, (1,3) as well as improving dynamic compliance (4) and static compliance. (5,6) One of a number of respiratory physiotherapy techniques, MH is commonly used by physiotherapists in patients receiving MV. (5) Originally called "bag squeezing", MH consists of a series of deep breaths with a three-second inspiratory pause combined with expiratory rib cage compression (ERCC) and suctioning.…”

Objective: Although manual hyperinflation (MH) is widely used for pulmonary secretion clearance, there is no evidence to support its routine use in clinical practice. Our objective was to evaluate the effect that MH combined with expiratory rib cage compression (ERCC) has on the length of ICU stay and duration of mechanical ventilation (MV). Methods: This was a prospective randomized controlled clinical trial involving ICU patients on MV at a tertiary care teaching hospital between January of 2004 and January of 2005. Among the 49 patients who met the study criteria, 24 and 25 were randomly assigned to the respiratory physiotherapy (RP) and control groups, respectively. Of those same patients, 6 and 8, respectively, were later withdrawn from the study. During the 5-day observation period, the RP patients received MH combined with ERCC, whereas the control patients received standard nursing care. Results: The two groups were similar in terms of the baseline characteristics. The intervention had a positive effect on the duration of MV, as well as on the ICU discharge rate and Murray score. There were significant differences between the control and RP groups regarding the weaning success rate on days 2 (0.0% vs. 37.5%), 3 (0.0% vs. 37.5%), 4 (5.3% vs. 37.5%), and 5 (15.9% vs. 37.5%), as well as regarding the ICU discharge rate on days 3 (0% vs. 25%), 4 (0% vs. 31%), and 5 (0% vs. 31%). In the RP group, there was a significant improvement in the Murray score on day 5. Conclusions: Our results show that the use of MH combined with ERCC for 5 days accelerated the weaning process and ICU discharge.Keywords: Physical therapy modalities; Ventilator weaning; Length of stay. ResumoObjetivo: Embora a hiperinsuflação manual (HM) seja largamente usada para a remoção de secreções pulmonares, não há evidências para sua recomendação como rotina na prática clínica. O objetivo do estudo foi avaliar o efeito da HM combinada com compressão torácica expiratória (CTE) na duração de internação em UTI e no tempo de ventilação mecânica (VM) em pacientes sob VM. Métodos: Ensaio clínico prospectivo, randomizado e controlado com pacientes de UTI sob VM em um hospital acadêmico terciário entre janeiro de 2004 e janeiro de 2005. Dentre os 49 pacientes que preencheram os critérios do estudo, 24 e 25 foram randomicamente alocados nos grupos fisioterapia respiratória (FR) e controle, respectivamente, sendo que 6 e 8 foram retirados do estudo. Durante o período de observação de 5 dias, os pacientes do grupo FR receberam HM combinada com CTE, enquanto os controles receberam o tratamento padrão de enfermagem. Resultados: Os dois grupos apresentaram características basais semelhantes. A intervenção teve efeito positivo na duração de VM, alta da UTI e escore de Murray. Houve diferenças significativas entre os grupos controle e FR em relação à taxa de sucesso no desmame nos dias 2 (0,0% vs. 37,5%), 3 (0,0% vs. 37,5%), 4 (5,3 vs. 37,5%) e 5 (15,9% vs. 37,5%), assim como à taxa de alta da UTI nos dias 3 (0% vs. 25%), 4 (0% vs. 31%) e 5 (0% vs. 3...

“…1,2 It is commonly used to prevent and reverse atelectasis, 3 increase alveolar ventilation, 4 and mobilize secretions so they may be suctioned. 5,6 MHI has been shown to result in improvements in static and dynamic lung compliance, an increased yield of secretions, 2,4,5,7,8 and a trend in reducing ventilator-associated pneumonia. 9 Movement of secretions in intubated patients occurs by the process of annular 2-phase gas-liquid flow.…”
