Background: To evaluate clinical and laboratorial parameters that predict decreased respiratory function in patients subjected to coronary artery bypass graft surgery (CABG).
Material/methods: This was a prospective study evaluating 61 patients subjected to CABG with cardiopulmonary bypass, median sternotomy, and under mechanical ventilation for up to 24 h. One day before surgery, clinical information was recorded. Maximal inspiratory (MIP) and expiratory (MEP) pressures, and expiratory peak flow rate (EPFR) values were assessed 1 day before surgery and on the fifth postoperative day. Student's t test, 2-way ANOVA, Pearson's linear correlation, and logistic regression were used for statistical analysis.
Results: Patients were 63±10 years old, 67% males. Arterial hypertension was found in 75.4% of the patients, diabetes in 31.2%, dyslipidemia in 63.9%, tabagism in 25%, and chronic obstructive pulmonary disease (COPD) in 16.4%. Previous myocardial infarction was found in 67%. Preoperative hemoglobin levels were 12.8±1.71 g/dL. Older individuals had lower preoperative MEP and EPFR values. Preoperatively, positive association was found between hemoglobin levels and maximal respiratory pressures and EPFR values. Patients with both class III angina and COPD presented higher reductions in pulmonary pressures between the preoperative period and the 5th postoperative day.
Conclusions: Older age and low hemoglobin levels are associated with preoperative low maximal respiratory pressures and EPFR. The combination of severe angina and COPD results in higher postoperative reduction of maximal respiratory pressures for patients who underwent CABG.

A 52-year-old Japanese man with a history of childhood asthma presented at our emergency department with progressive dyspnea. Despite subcutaneous adrenaline injections, salbutamol nebulization, and intravenous methylprednisolone, the carbon dioxide partial pressure (pCO) increased to 110 mmHg. The patient was intubated, and mechanical ventilation was initiated because of severe respiratory failure.

Development of a Framework for the Hemodynamic Impact of Positive End-Expiratory Pressure in Normal and Heart Failure Conditions.

Positive end-expiratory pressure (PEEP) improves respiratory conditions. However, the complex interaction between PEEP and hemodynamics in heart failure patients makes it challenging to determine appropriate PEEP settings. In this study, we developed a framework for the impact of PEEP on hemodynamics considering cardiac function, by integrating the impact of PEEP in the generalized circulatory equilibrium framework, and validated the framework by assessing its ability to accurately predict PEEP-induced hemodynamics.

Objective: To verify the association between different types of ambient ventilation in Central Sterile Supply Department (CSSD), fractional exhaled nitric oxide (FeNO) values, and respiratory symptoms of workers .
Methods: CSSD workers from five hospitals were evaluated in three different ventilation systems: negative air pressure, air conditioning, and natural ventilation. The prevalence of respiratory symptoms was evaluated by The European Community Respiratory Health Survey.
Remote monitoring of patients with COPD disease using a tablet system: a randomised crossover study of quality-of-life measurements.

Background: Remote patient monitoring (RPM) has been evaluated in COPD, but with varying results. We aimed to evaluate whether a tablet system that monitors disease-related parameters in patients with COPD could influence physical and mental health-related quality of life, compared with usual care (UC).
Methods: 70 patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) group D COPD (61% women, aged 71±8 years, forced expiratory volume in 1 s % predicted 41±13%, COPD Assessment Test (CAT) 19±7 points) were recruited at the COPD centre in Gothenburg, Sweden, and randomised to a tablet-based RPM system or UC for a 26-week period, after which they crossed over to the alternative management for another 26 weeks.
