Filter by:For adult patients with acute respiratory failure requiring invasive mechanical ventilation, does a ventilation strategy using proportional assist ventilation with load-adjustable gain factors (PAV+) result in a shorter duration of time spent on mechanical ventilation than a ventilation strategy using pressure support ventilation (PSV)?
In immunocompromised patients, Acute Respiratory Failure (ARF) is associated with a high case-fatality, particularly when invasive Mechanical Ventilation (MV) is required. In the most hypoxemic patients, oxygen administration through High Flow Nasal Cannula (HFNC) has been reported as an alternative to the venturi mask. The aim of this study is to compare HFNC and venturi mask on early respiratory deterioration and patient's comfort in that setting. The investigators planned a prospective randomized study in 4 Intensive Care Units (ICUs). As respiratory deterioration occurs early after ICU admission, patients are randomized to receive two hours of oxygen therapy either through HFNC or venturi mask. The primary endpoint is defined as the need for invasive or noninvasive MV in the 2-hour period. Secondary endpoints include comfort, dyspnea and thirst.
This study aimed to investigate the effect of enteral feeding's macronutrient composition on inflammatory mediators, oxidative stress and outcomes in Intensive Care Unit (ICU) patients with acute respiratory failure. In this double-blind randomized control trial, 42 patients of both sexes and diagnosed with acute respiratory failure in ICU that receive enteral feeding, will be randomly assigned to three groups of 14 each. First Intervention group; high-protein low-carbohydrate diet with high olive oil, the second intervention group; high-protein low-carbohydrate diet with high sunflower oil and control; high-protein kitchen formula. Intravenous levels of uric acid, high sensitive C-Reactive Protein (hs-CRP), Interleukin 6 (IL-6) and Total Antioxidant Capacity (TAC) measured at days 0 and 10. As well as, organ failure, duration of ventilation, length of ICU stay and mortality rates will be evaluated.
The overall objective of this study is to determine if Vapotherm high flow nasal cannula therapy (HFT), when used to treat respiratory failure in the ED, is at least equivalent to the current standard of care for non-invasive ventilatory support, non-invasive positive pressure mask ventilation (NIPPV). Moreover, this study will investigate the potential that HFT has possible advantages over NIPPV, such as decreased time to patient stability from respiratory failure, and the ease of use as a first line intervention for respiratory failure in the ED environment. The hypothesis is that HFT via the Vapotherm Precision Flow will demonstrate clinical non-inferiority when compared to NIPPV with regard to treatment failure by way of an impact on ventilation indices and a lower intolerance rate, and have a positive association with hospital disposition and length of stay.
A three-arm, randomized, pilot feasibility, study to assess the effect three validated sedation strategies on outcomes of patient on mechanical ventilation.
Patients with chest wall elastance increasing could worsen lung function. Increasing of chest wall elastance plays a great role in lung mechanics, and could influence mechanical ventilation settings. Therefore, It could help the physicians to find appropriate indicators and optimize the treatments of ARF patients to explore the mechanisms of lung mechanics changse in the patients with high chest wall elastance.
Lower lobe atelectasis of the lung is common in Acute Respiratory Distress Syndrome (ARDS) and has the potential to adversely impact lung compliance and intra-pulmonary shunt. The cephalic shift of the diaphragm and dorsal atelectasis associated with the commonly used supine position might also contribute to this shunt. Reports indicate that obese patients may be more likely to develop dorsal atelectasis than non-obese patients. The investigators hypothesized that opening the body position angle at the waist from a typical head of bed at 30 degrees to one similar to a more upright reverse trendelenburg position, would alter the position of the diaphragm downward, allowing for improved aeration of lung bases. Thus, the investigators examined the upright body positioning in mechanically ventilated patients with ARDS primarily by evaluating for effects on oxyhemoglobin saturation (O2sat), Tidal Volume (TV) and Respiratory Rate (RR).
Determining the optimal Neurally Adjusted Ventilatory Assist (NAVA) level remains challenging, and several methods have been suggested. However none of them seems easily utilisable. Thus the investigators propose to test a way of NAVA level titration according to ventilator comfort.
Patients with severe chronic diseases are often admitted to the hospital complaining of shortness of breath. Some of these patients decide that they do not want placement of a breathing tube in the windpipe to assist their breathing. In this situation, these patients are treated with oxygen, a variety of medications like morphine or masks that are connected to breathing machines, something called bilevel positive airway pressure (BiPAP) or noninvasive ventilation (NIV), to help with their breathing. Not much is known about how much noninvasive ventilation helps these patients, especially how comfortable they feel with it and how much their families think it helps. Our aim is to monitor use of ways to help breathing in patients who don't want a breathing tube, see how often noninvasive ventilation is used and ask surviving patients, patient's families and caregivers about their experience with noninvasive ventilation and how much it seemed to help. With our findings, we hope to improve the use of noninvasive ventilation in these patients and come up with ways to relieve their shortness of breath and provide as much comfort as possible.
The purpose of this study is to determine whether, as compared with the Venturi mask, a nasal, high-flow oxygenation device (Optiflow) may reduce the extubation failure rate in patients needing oxygen therapy after extubation.
