OBJECTIVE: During cardiac surgery, several factors contribute to the development of postoperative pulmonary complications. Non-invasive ventilation is a promising therapeutic tool for improving the functionality of this type of patient. The aim of this study is to evaluate the functional capacity and length of stay of patients in a nosocomial intensive care unit who underwent prophylactic non-invasive ventilation after heart valve replacement. METHOD: The study was a controlled clinical trial, comprising 50 individuals of both sexes who were allocated by randomization into two groups with 25 patients in each group: the control group and experimental group...

BACKGROUND: Advanced neurology diseases including motor neuron disease (MND) are usually progressive life-limiting illness and could be devastating for patients, families and caregivers. Although medical technologies, such as enteral feeding and non-invasive ventilation, may prolong life expectancy of the patients, their utilization prompts important ethical questions in regard to their quality of life (QoL). Little attention had been paid on how ACP practice would practically help with patients suffering from different neurology diseases...

Diaphragm dysfunction is common in clinical work, which is a frequently important cause of ventilation weaning failure ignored by clinicians. Assessing diaphragmatic function while weaning helps early detection and prevention of weaning failure, so as to improve the clinical outcome of patients on mechanical ventilation (MV). Reviewing studies of diaphragmatic function evaluation in weaning, we can find that assessing diaphragmatic function during weaning can help guide weaning. Weaning predictors including pressure index, electrophysiological index and morphological index, among which bedside ultrasound as a morphological index is widely used in intensive care unit (ICU), which is simple, non-invasive, and easy to operate...

Today, invasive and non-invasive home mechanical ventilation have become a well-established treatment option. Consequently, in 2010 the German Society of Pneumology and Mechanical Ventilation (DGP) has leadingly published the guidelines on "Non-Invasive and Invasive Mechanical Ventilation for Treatment of Chronic Respiratory Failure". However, continuing technical evolutions, new scientific insights, and health care developments require an extensive revision of the guidelines.For this reason, the updated guidelines are now published...

PURPOSE OF REVIEW: Aim of this article is to review evidence recently generated on the application of extracorporeal carbon dioxide removal (ECCO2R) in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) requiring mechanical ventilation (invasive and non invasive) for hypercapnic respiratory failure. RECENT FINDINGS: To date, the paucity of evidences on ECCO2R to decrease the rate of noninvasive ventilation (NIV) failure and to wean hypercapnic patients from invasive mechanical ventilation (IMV) precludes to systematically apply this technology to COPD patients...

BACKGROUND: Early detection of respiratory overload is crucial to mechanically ventilated patients, especially during phases of spontaneous breathing. Although a diversity of methods and indices has been established, there is no highly specific approach to predict respiratory failure. This study aimed to evaluate acceleration sensors in abdominal and thoracic wall positions to detect alterations in breathing excursions in a setting of gradual increasing airway resistance. METHODS: Twenty-nine healthy volunteers were committed to a standardized protocol of a two-minutes step-down spontaneous breathing on a 5 mm, 4 mm and then 3 mm orally placed endotracheal tube...

The advent of one-lung ventilation (OLV) technique provides immobilized surgical field which is fundamental in minimally invasive thoracic surgery. Mainstem methods of achieving lung separation are either via a double-lumen endotracheal tube or placing a bronchial blocker (BB) through a single-lumen endotracheal tube. More recently, the use of non-intubated thoracic surgery (NITS) has been investigated intensively, attempting to minimise the complications that follow general anaesthesia. The aim of this review is to describe the mechanism of these techniques briefly and outlines the advantages and drawbacks of them with the comparison...

INTRODUCTION: Our knowledge of acute respiratory distress syndrome (ARDS) pathogenesis is incomplete. The goal of this pilot study is to investigate the feasibility of measuring lower airways inflammation in patients with ARDS using repeated endotracheal aspirates (ETAs). METHODS: ETAs were obtained within 24 hours by intensive care unit admission from 25 mechanically ventilated patients with ARDS and 10 of them underwent a second ETA within 96 hours after the first sampling...

After birth, extremely preterm infants often require specialized respiratory management in the form of invasive mechanical ventilation (IMV). Protracted IMV is associated with detrimental outcomes and morbidities. Premature extubation, on the other hand, would necessitate reintubation which is risky, technically challenging and could further lead to lung injury or disease. We present an approach to modeling respiratory patterns of infants who succeeded extubation and those who required reintubation which relies on Markov models...

In this paper we present a method for the estimation of leaks in non-invasive ventilation. Accurate estimation of leaks is a key component of a ventilator, since it determines the ventilator performance in terms of patient-ventilator synchrony and air volume delivery. In particular, in non-invasive ventilation, the patient flow is significantly different from the flow measured at the ventilator outlet. This is mostly due to the vent orifice along the tube that is used for exhalation, but also to the non-intentional leaks that occur elsewhere in the circuit (e...

RATIONALE: Obesity is relatively common among individuals with chronic obstructive pulmonary disease (COPD). However, little is known about the association of obesity with severity of acute exacerbation of COPD (AECOPD) and in-hospital mortality. OBJECTIVES: To examine the association of obesity with severity markers of AECOPD and in-hospital mortality. METHODS: This is a retrospective cohort study using population-based data - the 2012-2013 State Inpatient Databases - of seven US states (Arkansas, Florida, Iowa, Nebraska, New York, Utah, and Washington)...

OBJECTIVE: To evaluate the ability of pulse wave transit time (PWTT) to detect changes in stroke volume (SV) and to estimate cardiac output (CO) compared with the thermodilution technique in isoflurane-anaesthetized dogs. STUDY DESIGN: Prospective, experimental study. ANIMALS: Eight adult laboratory dogs. METHODS: The dogs were anaesthetized with isoflurane and mechanically ventilated. Reference CO (TDCO) was measured via a pulmonary artery catheter using the thermodilution technique and reference SV (TDSV) was calculated...

Background: Cerebral autoregulation (CA) is the mechanism that maintains constancy of cerebral blood flow (CBF) despite variations in blood pressure (BP). Patients with attenuated CA have been shown to have an increased incidence of peri-operative stroke. Studies of CA in anaesthetized subjects are rare, because a simple and non-invasive method to quantify the integrity of CA is not available. In this study, we set out to improve non-invasive quantification of CA during surgery. For this purpose, we introduce a novel method to amplify spontaneous BP fluctuations during surgery by imposing mechanical positive pressure ventilation at three different frequencies and quantify CA from the resulting BP oscillations...
