Filter by:The aim of this study is to compare two methods of delivery of noninvasive mechanical ventilation (NIV). Since patient compliance and mechanical characteristics of the delivery devices are two fundamental variables in the success of NIV during acute respiratory failure, our hypothesis is that an improved patient-ventilator interface may improve the efficacy of therapy.
Despite widely used of nasal CPAP in preterm infants, uncertainties regarding aspects of its application remain. Clinical indications vary greatly between institutions, especially when combined with varieties of systems, devices, and techniques available. One of the controversial aspects that needs to be clarified is the level of pressure which should be used. The objective of the study is to compare the effectiveness of two ranges of nCPAP pressure that are within the spectrum of current practice for post-extubation support in very preterm infants.
The purpose of this study is to compare the efficacy of a computer-assisted ventilator weaning system (Drager Smartcare) to our current standard of care in the medical intensive care unit.
The purpose of this study is to compare the efficacy of CPAP application by a helmet and O2 administration by a Venturi mask in terms of gas exchanges improvement in patients with acute respiratory failure due to community-acquired pneumonia.
An important part of how we decide when a patient is ready to have their breathing tube removed is to have a person breathe without any machine breaths while the breathing tube is still in place. We call this a spontaneous breathing trial. Commonly, while patients have the breathing tube, they are given medications to keep them sedated and comfortable so breathing does not bother them. These medicines are often stopped before the spontaneous breathing trial so they can be more awake for the test. There are signs the doctors look for during the spontaneous breathing trial that suggest the patient might not be ready for the breathing trial to come out. Signs like fast breathing, small breaths, a fast heart rate, or looking more anxious than usual may mean that the patient is not ready to come off the ventilator. However, if someone has been given sedation medicines the entire time they have had a breathing tube and are then woken up, they may naturally get very anxious. They may show the same signs as someone who is failing their breathing test, but in their case these signs are only because they are anxious.Doctors may mistake these signs as failing the breathing test and may not pull the breathing tube out even though the patient is really ready for it to come out. We wish to try and find out if patients do better during their spontaneous breathing trials if they are continued on some sedative medicines to treat anxiety or if they do better if the medicines are stopped before the test.
Glutamine is an amino acid which is rapidly depleted in critical illness. It is used as energy by cells that line the gut, vital for immune system function, and works as an anti-oxidant. Glutamine supplementation has been shown to improve outcomes in ICU patients. We hypothesize that critically ill patients given extra glutamine will have less of an inflammatory response and therefore better outcomes than patients not given extra glutamine. Our study randomizes patients to tube feeding with OR without extra glutamine to see if it affects patient outcomes as well as markers of inflammation.
Obesity is a significant health care issue in the United States, particularly among the critically ill. Preliminary research has shown that differences in ventilator management exist among obese and non-obese individuals. This study will examine the effect of excess weight on ventilator management and clinical outcomes in individuals in an intensive care unit (ICU).
Total-face mask may improve the efficacy of NIV compared to conventional face mask in patients with acute respiratory failure due to enhanced tolerance and the allowance of higher airway pressure without massive leaks.MAIN OBJECTIVE: To assess, in acute respiratory failure patients, whether the total-face mask reduce the intubation rate. METHODS: 300 patients admitted in the ICU for acute respiratory failure needing continuous noninvasive mechanical ventilation. The type of mask (total-face vs. conventional face mask) will be randomized. Defined failure criteria and weaning technique will be used.
This is a phase III trial comparing early tracheotomy versus prolonged endotracheal intubation in intensive care unit patients needing prolonged ventilatory support.
The purpose of this study is to determine the effect of nitric oxide for inhalation on the duration of mechanical ventilation in pediatric patients with AHRF.
