Non-invasive ventilation is increasingly used for respiratory support in preterm infants, and is associated with a lower risk of chronic lung disease. However, this mode is often not successful in the extremely preterm infant in part due to their markedly increased chest wall compliance that does not provide enough structure against which the forces of inhalation can generate sufficient pressure. To address the continued challenge of studying treatments in this fragile population, we developed a nonlinear lumped-parameter respiratory system mechanics model of the extremely preterm infant that incorporates nonlinear lung and chest wall compliances and lung volume parameters tuned to this population...

BACKGROUND: Invasive mechanical ventilation (IMV) is associated with the development of adverse pulmonary and non-pulmonary outcomes in very premature infants. Various modes of non-invasive respiratory support are increasingly being used to decrease the incidence of bronchopulmonary dysplasia. The aim of this trial is to compare the effect of non-invasive high-frequency oscillatory ventilation (NHFOV) and nasal continuous positive airway pressure (NCPAP) in preterm infants with respiratory distress syndrome (RDS) as a primary non-invasive ventilation support mode...

Epidemiological studies on pressure ulcers (PUs) in hospitalised infants are scarce. Spain lacks comprehensive research studies providing data on the prevalence or incidence in this population. This work was developed to determine the incidence of PUs in hospitalised infants admitted to intensive and intermediate care units, along with relevant risk factors and preventive measures. A prospective study appraising the incidence of PUs in infants was performed. The risk factors and preventive measures were evaluated using a multivariate logistic regression model...

The hypothesis of this study is that muscular activity measured through surface electromyography (sEMG) is useful to estimate the work of breathing (WOB) and respiratory mechanics. Thirty-two healthy volunteers were non-invasively ventilated, and an airflow resistor was attached to the airway circuit. sEMG signals from diaphragm, intercostal and sternocleidomastoid muscles were processed and compared with WOB changes. The airway resistance was increased from a median of 9.58 to 22.51 cmH2 O/L/s adding a resistance of 20 cmH2 O/L/s, achieving the lower compliance too...

BACKGROUND: Extubation failure (ExtF) is associated with prolonged hospital length of stay and mortality in adult cardiac surgery patients postoperatively. In this population, ExtF-related variables such as the arterial partial pressure of oxygen to fraction of inspired oxygen ratio (PaO2 /FiO2 ), rapid shallow breathing index, cough strength, endotracheal secretions and neurological function have been sparsely researched. AIM: To identify variables that are predictive of ExtF and related outcomes...

OBJECTIVES: We introduced an extubation strategy for emphysema patients after bilateral lung transplantation. Patients who met the extubation criteria were extubated in the operating room (OR) followed by non-invasive ventilation, and the other patients were extubated in the intensive care unit (ICU). The primary objective was to determine the extubation rate. The secondary outcomes were to determine the factors allowing for extubation in the OR and the postoperative course. METHODS: This study is a single-centre retrospective database analysis of 96 patients...

Patient-ventilator asynchrony may occur with modes of partial ventilatory support. Because this problem is associated with worsened outcomes, identifying and managing asynchronies has been recognized as a relevant clinical problem during both invasive and non-invasive (NIV) mechanical ventilation. Areas covered: In this review article, we first describe the different forms of patient-ventilator asynchrony and how they are classified and quantified. Then, we show how these asynchronies can be recognized, considering the techniques used to properly detect asynchronies, by either ventilator waveform observation, or through systems based on more complexes mathematical algorithms, by means of adjunctive signals, such as the electrical activity of the diaphragm or esophageal pressure...

BACKGROUND: Functional hemodynamic parameters such as stroke volume and pulse pressure variation (SVV and PPV) have been shown to be reliable predictors of fluid responsiveness in mechanically ventilated patients. Today, different minimally- and non-invasive hemodynamic monitoring systems measure functional hemodynamic parameters. Although some of these parameters are described by the same name, they differ in their measurement technique and thus may provide different results. We aimed to test the performance of seven functional hemodynamic parameters simultaneously in the same clinical setting...

Aims: Increases in left ventricular filling pressure are a fundamental haemodynamic abnormality in heart failure with preserved ejection fraction (HFpEF). However, very little is known regarding how elevated filling pressures cause pulmonary abnormalities or symptoms of dyspnoea. We sought to determine the relationships between simultaneously measured central haemodynamics, symptoms, and lung ventilatory and gas exchange abnormalities during exercise in HFpEF. Methods and results: Subjects with invasively-proven HFpEF (n = 50) and non-cardiac causes of dyspnoea (controls, n = 24) underwent cardiac catheterization at rest and during exercise with simultaneous expired gas analysis...

PURPOSE: Flail chest was traditionally treated non-operatively using mechanical ventilation and pain control. In order to reduce the occurrence of ventilation-associated complications and long-term disability, operative rib fixation is becoming a proven standard therapy for these patients. However, the consequences of the surgical complications may influence success rates negatively. The aim of this study was to compare the outcome of flail chest treatment by surgical rib fixation with non-operative treatment, with special focus on the impact of surgical complications...

Decision making in advanced Amyotrophic Lateral Sclerosis (ALS) patients keeps on being a controversial issue. The aim of this work is to discuss ethical implications of withdrawing respiratory support treatment in patients with ALS. Through a bibliographic search on Pubmed database (2010-2016) we investigated whether or not the use of Non-Invasive Ventilation (NIV) and Mechanical Ventilation (MV) would increase survival and quality of life. We included 38 review articles. From these papers, results and ethical implications of initiating and mainly withdrawing respiratory support were analyzed...

BACKGROUND: Identifying mechanisms to improve provider compliance with quality metrics is a common goal across medical disciplines. Nudge interventions are minimally invasive strategies that can influence behavioural changes and are increasingly used within healthcare settings. We hypothesised that nudge interventions may improve provider compliance with lung-protective ventilation (LPV) strategies during general anaesthesia. METHODS: We developed an audit and feedback dashboard that included information on both provider-level and department-level compliance with LPV strategies in two academic hospitals, two non-academic hospitals and two academic surgery centres affiliated with a single healthcare system...

The growing interest in the quality of patient care at the levels of the health care managers, insurance companies, and health professionals is evident. Further, the growing population requires good quality health services. In this review, we analyzed the cost-effectiveness of noninvasive ventilation (NIV) in an acute setting for the treatment of respiratory failure. The strength of this review is that it identified and summarized the most relevant studies regarding various aspects of the cost-utility of NIV in an acute setting...

BACKGROUND: Interstitial lung diseases (ILDs) are a heterogeneous group of diseases characterized by widespread fibrotic and inflammatory abnormalities of the lung. Respiratory failure is a common complication in advanced stages or following acute worsening of the underlying disease. Aim of this review is to evaluate the current evidence in determining the best management of acute respiratory failure (ARF) in ILDs. METHODS: A literature search was performed in the Medline/PubMed and EMBASE databases to identify studies that investigated the management of ARF in ILDs (the last search was conducted on November 2017)...

Recent research suggested an important role for pulmonary extracellular adenosine triphosphate (ATP) in the development of ventilation-induced lung injury. This injury is induced by mechanical deformation of alveolar epithelial cells, which in turn release ATP to the extracellular space. Measuring extracellular ATP in exhaled breath condensate (EBC) may be a non-invasive biomarker for alveolar deformation. Here, we study the feasibility of bedside ATP measurement in EBC. We measured ATP levels in EBC in ten subjects before and after an exercise test, which increases respiratory parameters and alveolar deformation...

BACKGROUND: Patients in the intensive care unit (ICU) experience sleep deprivation caused by environmental disruption, such as high noise levels and 24-hour lighting, as well as increased patient care activities and invasive monitoring as part of their care. Sleep deprivation affects physical and psychological health, and patients perceive the quality of their sleep to be poor whilst in the ICU. Artificial lighting during night-time hours in the ICU may contribute to reduced production of melatonin in critically ill patients...

There is limited literature on non-invasive mechanical ventilation (NIMV) in patients with polytrauma-related acute respiratory failure (ARF). Despite an increasing worldwide application, there is still scarce evidence of significant NIMV benefits in this specific setting, and no clear recommendations are provided. We performed a systematic review, and a search of clinical databases including MEDLINE and EMBASE was conducted from the beginning of 1990 until today. Although the benefits in reducing the intubation rate, morbidity and mortality are unclear, NIMV may be useful and does not appear to be associated with harm when applied in properly selected patients with moderate ARF at an earlier stage of injury by experienced teams and in appropriate settings under strict monitoring...
