“…15 In clinical practice, respiratory muscle weakness may be associated with hypercapnia, recurrent respiratory infections and inefficient coughing, predisposing to the development of atelectasis, respiratory failure, compromising the ventilatory capacity and collaborating with the onset of more severe morbidities. 16,17 Thus, measuring respiratory muscle strength can help evaluate and manage different clinical conditions. Therefore, several studies were performed to generate normality values for maximal static respiratory pressures in children and in adults, demonstrating the influence of factors such as age, gender, weight and height.…”

“…Uma das formas de explicar a ocorrência disso é baseando-se no fato de que o sniff teste se trata de um esforço inspiratório balístico, curto e rápido, com forte ativação dos músculos diafragma e escaleno. Já a PImáx é uma medida que ativa todos os grupos musculares inspiratórios, por meio de uma contração isométrica sustentada 14,25 . Portanto, a SNIP tende a ser menor que a PImáx, pois a pressão gerada diminui com a realização de uma manobra mais rápida e, também, com o aumento da velocidade de encurtamento muscular 25 .…”

“…Fisiologicamente, no sniff teste, há um forte acionamento neuromuscular do diafragma e do escaleno, ocorrendo uma contração muscular balística, ao contrário da contração isométrica sustentada dos músculos inspiratórios que acontece na manobra de aquisição da PImáx 14 . Dessa forma, o sniff teste corresponde a um esforço natural que muitos pacientes acreditam ser de mais fácil realização quando comparado ao esforço preciso para desempenhar uma manobra estática, como a PImáx 9,10,15 .…”

original RESUMOObjetivo. Avaliar a correlação entre medidas de pressão inspiratória máxima e de pressão inspiratória nasal, e comparar valores médios de força muscular respiratória entre diferentes dias de internação hospitalar em pacientes acometidos por acidente vascular cerebral (AVC). Método. Foram estudados 13 pacientes acometidos por AVC internados na Unidade de Cuidados Especiais II (UCE II) do Hospital Geral Dr. Waldemar Alcântara, Fortaleza-CE. A ficha de avaliação contemplou medidas referentes à força muscular respiratória em D1 (1º dia de internação) e D5 (5º dia de internação): pressão inspirató-ria máxima (PImáx), pressão expiratória máxima (PEmáx) e pressão inspiratória nasal (SNIP). Resultados. A média de idade dos participantes foi de 69,1±7,2 anos. Quando comparados no 1º e no 5º dia de internação (p≤0,05), houve diferença dos valores médios de PImáx (61,5±32 para 76±13,2), PEmáx (62,9±26 para 69,8±26,1) e SNIP (33,3±12 para 39,4±12,2). Foi obtida correlação positiva moderada (r=0,60, p=0,001) entre PImáx e SNIP. Conclusão. Observou-se aumento significativo da força muscular respiratória durante a internação e os valores de PImáx e SNIP pareceram assemelhar-se em pacientes acometidos por AVC. ABSTRACTObjective. To evaluate the correlation between measures of maximal inspiratory pressure and nasal inspiratory pressure, and compare average values of respiratory muscle strength between different days of hospitalization in stroke patients. Method. 13 stroke patients admitted to the Unit of Special Care II (UCE II) of Hospital Geral Dr. Waldemar Alcântara, Fortaleza-CE, were studied. The evaluation sheet contemplated measures regarding respiratory muscle strength in D1 (1st day of hospitalization) and D5 (5nd day of hospitalization): maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP) and nasal inspiratory pressure (SNIP). Results.

“…The value of portable manometry in assessing respiratory muscle strength has been addressed in previous studies [7,15,21]. The present study differs to the previ-ous ones and complements them in that it consists of a large number of subjects and it incorporates young children and patients with Cystic Fibrosis.…”

Introduction: Respiratory muscle strength can be assessed by static mouth measurements of maximal inspiratory pressure (Pimax) and maximal expiratory pressure (Pemax). Impaired respiratory muscle strength is common in neuromuscular and obstructive pulmonary disease such as Cystic Fibrosis (CF). Maximal respiratory pressures can easily be measured with a portable manometer on the bedside and in the community. Our objective was to compare maximal respiratory pressures as measured by standard laboratory equipment and the portable mouth pressure meter Micro RPM. Methods: Pimax and Pemax were assessed in 296 healthy subjects and patients with CF with the Micro RPM and standard laboratory equipment. The Micro RPM measures and digitally displays maximal respiratory pressures after averageing over a one second period. Standard laboratory equipment consisted of a differential pressure transducer, whose amplified signals were analyzed by Lab-VIEW software. Each subject performed at least five reproducible maneuvers after familiarizing with the equipment. Results: The Micro RPM accurately measured maximal inspiratory and maximal expiratory pressures both in healthy individuals as well as in patients with CF. Mean difference (standard deviation) of the methods was 1.37 (17.73) cm H2O for Pimax maneuvers and 1.84 (9.09) cm H2O for Pemax maneuvers. Conclusions: The Micro RPM can relia-bly and accurately measure maximal respiratory mouth pressures and its use could be applied both in the clinical and the research setting.
