PURPOSE: The purpose of this study was to determine the effect of aerobic training under noninvasive positive pressure ventilation (NPPV) on maximal oxygen uptake ([Formula: see text]). METHODS: Ten healthy young male volunteers participated in the study. Before the training, stroke volume (SV) and cardiac output (CO) were measured in all subjects under 0, 4, 8, and 12 cmH2O NPPV at rest. Then, the subjects exercised on a cycle ergometer at 60% of pre-training [Formula: see text] for 30 min daily for 5 consecutive days with/without NPPV...

RATIONALE: Bronchiolitis is the most common lower respiratory infection in infants; however, it remains unclear which infants with bronchiolitis will develop severe illness. In addition, while emerging evidence indicates associations of the upper-airway microbiome with bronchiolitis severity, little is known about the mechanisms linking airway microbes and host response to disease severity. OBJECTIVES: To determine the relations among the nasopharyngeal airway metabolome profiles, microbiome profiles, and severity in infants with bronchiolitis...

BACKGROUND: Overshoot phenomena of the gas exchange ratio (R:VCO2/VO2), ventilatory equivalent for O2 (VE/VO2), and end-tidal O2 pressure (PETO2) are commonly observed during recovery from maximal cardiopulmonary exercise testing (CPX). We investigated the clinical significance of the overshoots of these indices by comparing their magnitudes between healthy subjects and cardiac patients with left ventricular dysfunction. METHODS: In total, 121 subjects (73 healthy subjects and 48 cardiac patients with left ventricular ejection fraction<40%) who underwent CPX and achieved peak R≥1...

Importance: Outcomes after exacerbations of chronic obstructive pulmonary disease (COPD) requiring acute noninvasive ventilation (NIV) are poor and there are few treatments to prevent hospital readmission and death. Objective: To investigate the effect of home NIV plus oxygen on time to readmission or death in patients with persistent hypercapnia after an acute COPD exacerbation. Design, Setting, and Participants: A randomized clinical trial of patients with persistent hypercapnia (Paco2 >53 mm Hg) 2 weeks to 4 weeks after resolution of respiratory acidemia, who were recruited from 13 UK centers between 2010 and 2015...

In recent years, laser resection of lung metastases has been established as the standard procedure worldwide. To avoid airway fire, it is necessary to collapse the surgical lung. The selective lobar bronchial blockade is a technique that allows one-lung ventilation while the operated lobe is collapsed in patients with previous pulmonary resection requiring subsequent resection or with limited pulmonary reserve. We report a clinical case about our experience of a selective lobar bronchial blockade technique with a bronchial blocker (Coopdech endobronchial blocker) that was employed successfully with a double-lumen endotracheal tube in a patient with previous contralateral pulmonary resection who was scheduled for atypical resections of pulmonary metastases by laser...

Recently, the cognitive abilities of patients with amyotrophic lateral sclerosis (ALS) have been found to be impaired along with the neurodegeneration of motor neurons. Electroencephalography (EEG) of end-stage ALS patients has reportedly shown specific features based on neuronal network modulations, differing from EEG of other patients with cognitive failure and dementia. However, EEG of end-stage ALS patients during anaesthesia has not yet been reported. A 64-year-old male ALS patient with locked-in state (LIS), supported by tracheostomy positive-pressure ventilation (TPPV) and enteral nourishment for 9years, underwent scheduled general anaesthesia for repair of a fractured mandible...

BACKGROUND: Increased augmentation index (AIx) is accompanied by an elevated cardiovascular risk. A reduction of AIx is known for long-term continuous positive airway pressure (CPAP) therapy. We hypothesised that acute preload and left ventricular workload effects AIx and subendocardial viability ratio (SEVR) as a marker of coronary flow reserve. METHODS: Increased augmentation index and central blood pressure parameters were measured by radial artery tonometry in 17 healthy men (32/±6years) at rest and during CPAP ventilation at pressures of 5, 10mbar and after recovery...

I am glad to see that the Sustained Lung Inflation (SLI) trial (1) still draws a great deal of attention and I would like to clarify some aspects of the trial, in response to the comments by Gupta and Argarwal (2) in Acta Paediatrica. A meta-analysis carried out in 2016 demonstrated that starting non-invasive respiratory support from birth could reduce the incidence of bronchopulmonary dysplasia and death. However, about 50% of very low birth weight infants who are initially on nasal continuous positive airway pressure need subsequent intubation and mechanical ventilation...

CASE: A 44-year-old man intentionally stabbed himself in the anterior neck and left thorax with a fruit knife. Physical examination revealed two open wounds entering the thoracic cavity in the front chest, and a stab wound entering the trachea at the neck. Two chest tubes were initially inserted for the left lung injury with open hemopneumothorax. Nevertheless, the worsening oxygenation required positive pressure ventilation (PPV) with endotracheal intubation. OUTCOME: Right hemiparesis was found during weaning from PPV...

Lung ischemia-reperfusion injury remains a major complication after lung transplantation. Variable ventilation (VV) has been shown to improve respiratory function and reduce pulmonary histological damage compared to protective volume-controlled ventilation (VCV) in different models of lung injury induced by endotoxin, surfactant depletion by saline lavage, and hydrochloric acid. However, no study has compared the biological impact of VV vs. VCV in lung ischemia-reperfusion injury, which has a complex pathophysiology different from that of other experimental models...

BACKGROUND: Previous research has suggested correlations between the end-tidal partial pressure of carbon dioxide (PETCO2) and the partial pressure of arterial carbon dioxide (PaCO2) in mechanically ventilated patients, but both the relationship between PETCO2 and PaCO2 and whether PETCO2 accurately reflects PaCO2 in neonates and infants are still controversial. This study evaluated remote sampling of PETCO2 via an epidural catheter within an endotracheal tube to determine the procedure's clinical safety and efficacy in the perioperative management of neonates...

BACKGROUND AND OBJECTIVE: Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) (AE-IPF) is a poor prognostic disorder. AE is also reported to occur in other idiopathic interstitial pneumonias (IIPs). There are limited data available regarding the effectiveness of treatment for AE-IIPs. The objective of this study was to clarify the prognostic impact of the initial dose of prednisolone (PSL) for treating AE-IIPs. METHODS: Eighty-five patients with AE-IIPs, diagnosed according to the criteria of the Japanese Respiratory Society, were enrolled in this study (IPF/non-IPF: 63/22 patients) from 2004 to 2013...

Noninvasive ventilation is an important respiratory management technique for the treatment of mild or moderate respiratory failure in the neonatal intensive care unit. Its reasonable application can effectively avoid the use of invasive ventilation and related complications. Recent studies have found that noninvasive high-frequency oscillatory ventilation has the advantages of both nasal continuous positive airway pressure and high-frequency ventilation and can rapidly improve oxygenation, effectively remove carbon dioxide, and improve respiratory failure...

The aim of this retrospective single-institution observational study was to identify whether the frequency of hospitalizations for pneumonia would change before and after the initiation of noninvasive positive pressure ventilation in children with neurological conditions. Included patients were 1 to 18 years old with an underlying neurological disease and had been prescribed nocturnal noninvasive positive pressure ventilation. The authors excluded patients with a tracheostomy or those who used noninvasive positive pressure ventilation solely for obstructive sleep apnea...

Univent tube (UT) and EZ-blocker were used for one-lung ventilation (OLV). UT is a single lumen tube with a small separate lumen containing a bronchial blocker. EZ-blocker differs with its unique y-shaped double-cuffed distal end. We aimed to compare these two airway devices effects on airway pressures, oxygenation, ventilation and haemodynamics during OLV. Patients undergoing elective thoracotomy for the first time were included in this prospective randomized study. Patients were divided into two groups as UT and EZ...
