Neuromuscular diseases (NMD) are a group of rare heterogeneous disorders that may be accompanied by respiratory muscle weakness. The simplest measurements of respiratory muscle strength are maximum inspiratory pressure (PImax) and maximum expiratory pressure (PEmax) of the mouth. Inspiratory muscle weakness can also be evaluated by the sniff test (sniff nasal inspiratory pressure method). This study tested the agreements in PImax and PEmax (measured by using a plethysmograph and portable equipment) as well as the correlations of PImax and PEmax by using the sniff nasal inspiratory pressure method, lung function, and arterial blood gas parameters in subjects with NMD. ⋯ Measurements of PImax and PEmax by using portable equipment were equivalent to those performed by using the accepted standard, plethysmography, in the subjects with NMD. Noninvasive evaluation of the sniff test with the portable equipment correlates with PImax, which makes this approach a good method for measuring the maximum strength of inspiratory muscles in patients with NMD.

Recommendations regarding ventilation during cardiopulmonary resuscitation (CPR) are based on a low level of scientific evidence. We hypothesized that practices about ventilation during CPR might be heterogeneous and may differ worldwide. To address this question, we surveyed physicians from several countries on their practices during CPR. ⋯ Physicians indicated heterogeneous practices that often differ significantly from international CPR guidelines. This may reflect the low level of evidence and a lack of detailed recommendations concerning ventilation during CPR.

Common among patients with COPD is declining health-related quality of life (HRQOL). Although results of research identified some factors associated with HRQOL, resilience factors are yet to be fully investigated. ⋯ Resilience and confounding factors were of importance in the HRQOL of subjects with COPD. Thus, consultation with a medical professional, especially at discharge, who identifies, encourages, and approves of the patient's disease management abilities will enhance both resilience and HRQOL.

The time and conditions may not be suitable for performing polysomnography (PSG) before urgent or emergent surgeries, for example, a coronary artery bypass graft. Unavailability in many centers, critical clinical situation, and inability to arrange a timely scheduled appointment are other limitations for PSG. In this study, we aimed to investigate if the STOP-BANG Questionnaire may predict obstructive sleep apnea syndrome (OSAS) related postoperative pulmonary alterations during coronary artery surgery. ⋯ The STOP-BANG Questionnaire may predict the OSAS risk and OSAS-related pulmonary complications for patients who are candidates for a coronary artery bypass graft and unable to be evaluated with PSG before surgery due to technical or time-related limitations.
