PURPOSE High flow nasal cannula (HFNC) may decrease preload being associated with beneficial hemodynamic and respiratory effects in adults with heart failure. METHODS This is a sequential intervention prospective study including 10 adults with New York Heart Association (NYHA) class III and left ventricle ejection fraction 45% or less. High flow gas was(More)
Muscle involvement is found in most critical patients admitted to the intensive care unit (ICU). Diaphragmatic muscle alteration, initially included in this category, has been differentiated in recent years, and a specific type of muscular dysfunction has been shown to occur in patients undergoing mechanical ventilation. We found this muscle dysfunction to(More)
Primary graft dysfunction is a significant cause of lung transplant morbidity and mortality, but its underlying mechanisms are not completely understood. The aims of the present study were: 1) to confirm that right ventricular function is a risk factor for severe primary graft dysfunction; and 2) to propose a clinical model for predicting the development of(More)
Acute respiratory failure represents one of the most common causes of intensive care unit admission and oxygen therapy remains the first-line therapy in the management of these patients. In recent years, high-flow oxygen via nasal cannula has been described as a useful alternative to conventional oxygen therapy in patients with acute respiratory failure.(More)
OBJECTIVES To evaluate the prevalence of vitamin D deficiency in critically ill patients upon admission to an Intensive Care Unit (ICU) and its prognostic implications. DESIGN A single-center, prospective observational study was carried out from January to November 2015. Patients were followed-up on until death or hospital discharge. SETTING The(More)
BACKGROUND Primary graft dysfunction (PGD) remains a significant cause of lung transplant postoperative morbidity and mortality. The underlying mechanisms of PGD development are not completely understood. This study analyzed the effect of right ventricular function (RVF) on PGD development. METHODS A retrospective analysis of a prospectively assessed(More)
We thank Dr Esquinas [1] for his interesting and constructive comments on our article [2]. We agree that the study has several limitations that should be borne in mind when interpreting the results. As we pointed out in the discussion, we think that variations not only in intrathoracic pressure but also in lung volume may be responsible for the changes(More)
