To investigate the interindividual differences in respiratory sinus arrhythmia (RSA), recordings of ventilation and electrocardiogram were obtained from 12 healthy subjects for five imposed breathing periods (T(TOT)) surrounding each individual's spontaneous breathing period. In addition to the spectral analysis of the R-R interval signal at each breathing period, RSA characteristics were quant...

AIM To compare T-tube and pressure support ventilation (PSV) as two methods of mechanical ventilation weaning of patients with chronic obstructive pulmonary disease (COPD) after failed extubation. METHODS A prospective randomized trial carried out at the multidisciplinary intensive care unit (ICU) over 2 years included 136 patients with COPD who required mechanical ventilation longer than 24 ...

Abstract: Background There has been an exponential increase in modes of mechanical ventilation over the last couple decades. With this increase, there have paucity evidence which mode is superior to others or much guidance use a different disease status causing respiratory failure. Methods: An international survey six questions was posted on “society ventilation” website and advertised social m...

The purpose of this study was to elucidate the influence of inspiratory muscle fatigue on muscle sympathetic nerve activity (MSNA) and blood pressure (BP) response during submaximal exercise. We hypothesized that inspiratory muscle fatigue would elicit increases in sympathetic vasoconstrictor outflow and BP during dynamic leg exercise. The subjects carried out four submaximal exercise tests: tw...

With great interest we read the article in Critical Care by ten Hoorn et al. [1]. We appreciate the efforts of the authors to write the first review about interventions enabling communication with critically ill patients and to develop an algorithm to select a communication technique. Their attention was focused on patients who were completely ventilator dependent. In cases where tracheotomized...

Mechanical ventilation is currently the most widely used supportive therapy for treatment of moderate and severe hypoxemia any etiology. However, decision "when" right time to initiate withdrawal this support a matter debate worldwide. Many authors describe that disconnection process should be gradual in compliance with standards provide safety process; while other report it not feasible establ...

Weaning from mechanical ventilation imposes additional work on the cardiovascular system and can provoke or unmask left ventricular diastolic dysfunction with consecutive pulmonary edema or systolic dysfunction with inadequate increase of cardiac output and unsuccessful weaning. Echocardiography, which is increasingly used for hemodynamic assessment of critically ill patients, allows differenti...

Abstract The determination of respiratory parameters via respiration induced surface movements the upper body has been subject research for many years. displacements 102 motion capture markers were evaluated in this study terms their information content with respect to tidal volume recorded parallel using a spirometer. Independent breathing types (spontaneous breathing, abdominal or chest breat...
