Filter by:Patients who are intubated and mechanically ventilated for acute respiratory failure in the Intensive Care Unit (ICU) are at some point eligible for weaning. The common way to wean them from mechanical ventilation is to screen criteria for feasibility and, if present, to test feasibility by performing spontaneous breathing trial. This latter can be done either by setting a low pressure support level (expected to compensate the airflow resistance due to endotracheal tube) or by allowing the patient to breathe spontaneously through the tube without any support from the ventilator. Combination of low pressure assistance strategy (7 cm H2O) and positive expiratory pressure (PEP) of 4 cm H2O is the strategy used in our unit. Such a low pressure support level should actually result in a real assistance and, hence this is not the real spontaneous breathing capacity that is tested. Some ICU ventilators offer the option of compensating for the airflow resistance due to endotracheal tube, automatic tube compensation (ATC). Therefore, investigators aimed at comparing in patients ready to wean the usual procedure in our ICU and the ATC mode. In the ATC arm, the patients are breathing spontaneously through the endotracheal tube and are connected to the ventilator set at inspiratory pressure support of 0 cm H2O, PEP 4 cm H2O and ATC on. Two parallel arms depending on the order of allocation of each mode: pressure support 7 cm H2O + PEP 4 cm H2O then ATC or the opposite. The primary endpoint is the power of the work of breathing. The hypothesis is that the power of the work of breathing is greater in ATC than in the usual procedure, and hence this latter is a real ventilator support.
A previous study revealed that dysphagia preterm infants show statistically significant improvements in their swallowing mechanism when fed cold liquid barium when compared to room temperature liquid barium. The previous study was the first to identify these positive effects, although, only assessed 5 cold liquid swallows, immediately after the room temperature condition. This limited data set restricts the efficacy and safety of using cold liquids in clinical practice, emphasizing the need for further information. The present study aims to objectively assess the influence of cold liquid on the pharyngeal swallow mechanism in preterm infants with dysphagia after 10 minutes of a cold liquid feeding. The investigators will utilize videofluoroscopic swallow studies (VFSS) to analyze the frequency and severity of pharyngeal swallowing deficits during room temperature swallows and compare it to cold liquid swallows at various time points within a 10 minute feeding. Safety measures will also be obtained, such as participant axillary body temperature and gastric content temperature, to identify indicators for the development of cold stress.
This randomized, cross-over study aims at describing the effect of pursed lip breathing on exercise-induced dyspnea and exercise capacity in patients with interstitial lung disease.
Introduction: It is well established that physical fitness improves muscle performance either in sedentary people or in athletes. In this regard, specific exercises for respiratory muscles can result in better functional performance in hospitalized individuals, especially in critically ill patients in prolonged weaning. Objectives: To compare the following variables between intervention and control patients: success in weaning, free time off ventilator on ICU after weaning, and gain of muscle strength with the use of the inspiratory muscle training (IMT). Patients and methods: Prospective randomized controlled clinical trial. Only individuals on prolonged weaning will be enrolled. They will undergo IMT or will be managed in a conventional manner. The primary endpoint will be successful weaning. In addition, other variables such as free time off ventilator on ICU after weaning and muscle strength will be measured. In addition, mortality in the ICU, inside the hospital and after discharge will be followed for one year after study entrance. Expected results: According to the working hypothesis, it is expected that the performance of patients undergoing IMT will be superior to the conventional treatment. Also, their time to mortality is expected to be longer.
The standard procedure used for airway control in general anesthesia for LC (laparoscopic cholecystectomy) is endotracheal intubation (EI). AuraGain and I-Gel are supraglottic airway devices (SADs) used for airway control for certain types of surgeries. The aim of this study was to evaluate and compare the performances of new types of SADs with EI regarding their insertion times, durations, perioperative complications and effects on hemodynamic parameters and peak airway pressures (Paw) in LC as well.
Inspiratory muscle training (IMT) can reverse or delay the complications from the deterioration of inspiratory muscle function in asthma. Thus, the IMT has been considered a treatment option for people with asthma. The aim of this study is to investigate the training principles of intensity, specificity and reversibility of IMT in asthmatics.
This study is designed to evaluate the occurrence of gastric insufflation and the critical volume of the stomach after three different modes of positive pressure ventilation during induction (Manual-controlled, volume-controlled and pressure-controlled ventilation)
In patients undergoing elective coronary artery bypass grafting (CABG) surgery, coronary artery disease, sleep-disordered breathing (SDB), atrial fibrillation (AF) perioperative atrial fibrillation and complications will be assessed. The primary objective is to determine, whether SDB patients have a higher rate of Major Adverse Cardiac and Cerebrovascular Events (MACCE) within 30 days after surgery compared to those without SDB.
Breathing exercises are categorized as a mind-body practice. One in ten adults in the U.S. use breathing exercises for health purposes. The aim of this project is to examine if different slow breathing has different physiological and psychological effects.
The purpose of this study is to define the safety and the biochemical-physiological response of prolonged exposure to a normobaric low-oxygen environment in healthy volunteers.
