Filter by:Neurally adjusted ventilatory assist (NAVA) is a new concept of mechanical ventilation. NAVA delivers assistance to spontaneous breathing based on the detection of the electrical activity of the diaphragm. The investigators will study the effects of non-invasive NAVA on respiratory muscle unloading critically ill patients.
This study examines the feasibility of assessing sleep and circadian rhythmicity in critically ill patients undergoing mechanical ventilation. Secondarily, it will examine the feasibility of reducing subject exposure to environmental light and noise and of delivering routine care according to classical day/night routines.
Patients with respiratory failure following cardiac surgery are randomized to receive standard therapy versus non invasive ventilation. The hypothesis is that patients receiving non invasive ventilation will perform better than those who received standard therapy.
Exploration of the effects on diaphragmatic electrical activity (EMG) and on respiratory pattern of various level of assistance delivered by the ventilator in intubated spontaneously breathing patients in pressure support (PS) and in Neurally Adjusted Ventilatory Assist (NAVA) by step by step increasing of the level of assistance. Flow, airway pressure, transesophageal EMG signal and transcutaneous EMG signal will be recorded.
Airway pressures change during fiberoptic bronchoscopy and endotracheal suctioning. In this study pressure changes are examined in a mechanical lung model and in a population of ICU patients on mechanical ventilation.
The purpose of this study is - to document the prevalence and type of asynchronies incidence during non-invasive mechanical ventilation in pediatric patients breathing under pressure support. - to observe the impact of adjusting the expiratory trigger setting on asynchronies during pressure support - and compare these incidences with asynchronies measured in pediatric patient breathing under NAVA system (Neurally Adjusted Ventilatory Assist).
To evaluate the effectiveness of high assistance proportional assist ventilation (PAV+) (objective 80% gain) as main ventilatory support in early stage of critically ill patients in comparison with standard volume-assist control ventilation (ACV).
The aim of the study is to compare the efficacy and tolerance of autotitrating non-invasive ventilation (NIV) versus standard NIV in patients admitted to hospital with acute exacerbation of chronic respiratory failure. The investigators hypothesise that autotitrating NIV will ventilate patients with acute exacerbations of chronic respiratory failure as effectively as standard NIV.
The aim of the study is to investigate the effects of donor simvastatin treatment on ischemia-reperfusion injury after heart transplantation.
This is a Quasi-experimental research design. The subjects are limited in intensive care unit within north medical center hospital. All subjects depend on ventilator and receive weaning plans. Experimental group is weaning with the support of negative pressure ventilator .The investigators collect basic personal variables in the questionnaire, APACHE Ⅱ scale, Dyspnea scale and arterial blood gas analysis and ventilator weaning index. Compare experimental group and control group data. Data will be Statistical analyzed by: descriptive statistics (such as: mean, standard deviation, median, frequency, percentage) and inferential statistics (such as: Independent T-test, Pair T-test, Mann-Whitney U test), P-value <0.05 will consider to be statistically significant.
