Filter by:Some overweight individuals develop problems with their breathing such that they gradually breathe less and less. This leads to a lack of oxygen and a buildup of carbon dioxide in the blood, called ventilatory failure. As a consequence, if such a person develops a chest infection, they are more likely to become seriously ill and need intensive care. In addition they are much more likely to develop severe complications during and following operations. This problem can be treated with a machine at home used overnight to help breathing. It is interesting that ventilatory failure only happens in some overweight individuals, and the investigators do not understand what factors make this complication develop. There are a number of theories: for example the distribution of the fat, additional lung disease (such as asthma), the addition of obstructive sleep apnoea, a condition when there are periods of cessation of breathing overnight (which is more common in obese individuals), weak muscles of breathing (perhaps due to fatty infiltration of muscles or vitamin D deficiency), and other hormonal changes. The investigators intend to measure many potential factors in a range of overweight individuals, some who have ventilatory failure, and some who do not, to try and work out which are the important factors that cause this problem. If the investigators can identify such factors, then this will help predict in advance who is at risk from chest infections and during operations; thus allowing for earlier provision of an overnight breathing machine. This should reduce complications and potentially deaths in such individuals.
Nasal CPAP is a excellent ventilation modality for newborns, but the incidence of pneumothorax is high (65.% - 9%) our hypothesis is when the baby open the mouth or crie the pressure in the airway is variable, the investigators evaluate a closed system with a intubated baby with a orotracheal system but with a elastic reservoir , the reservoir distend and the pressure in the airway is constant ,with this system the investigators protect the lungs for damage . The investigators want compare the use of nasal CPAP, mechanical ventilation and orotracheal CPAP with a compensation bag (gregory system) in newborns with respiratory failure .
During assist control ventilation and pressure support ventilation (PSV), the start of ventilator inflation is determined by the start of the infant's inspiratory effort. During PSV, termination of inflation is determined by the level of the infant's inspiratory flow. In a randomized trial, no significant differences were found between assist control and pressure support ventilation with regard to the duration of weaning, time to successful extubation, work of breathing, rate of asynchrony and level of respiratory muscle strength.
The aim of the present study is to characterize the influence of an elevated positive end-expiratory pressure in patients with acute respiratory distress syndrome or acute lung injury on the cerebrovascular autoregulation.
The increasing rate of hospital-acquired infection and antibiotic resistance are major causes of prolonged ICU stay and death in hospitalized patients. The enormous impact of ICU-related infection demands the need for cost-effective therapies that can be rapidly implemented to improve patient immune response to control infection. Unfortunately, little high-quality comparative effectiveness research has been performed on micronutrient treatment regimens as methods to decrease hospital-acquired infection in critically ill patients. Critically ill medical and surgical patients have an extremely high prevalence of vitamin D insufficiency. We will perform a rigorous, double-blind, randomized, controlled, pilot clinical trial in ventilator-dependent ICU patients to test the clinical/metabolic safety and efficacy of two doses of oral high-dose vitamin D3 therapy versus standard therapy (no supplemental vitamin D). The primary endpoint is to test whether high-dose regimens [either 50,000 or 100,000 international units (IU) of enteral vitamin D3 given daily for 5 consecutive days (total dose = 250,000 or 500,000 IU, respectively) increase plasma 25(OH)D concentrations into a desirable range (> 30 ng/mL).
To evaluate a novel advanced physiological monitoring system to improve nocturnal non-invasive ventilation (NIV) in Neuromuscular disease (NMD), Chest wall disease (CWD), Chronic Obstructive Pulmonary Disease (COPD) and Obesity Hypoventilation Syndrome (OHS) patients. By enhancing sleep comfort, adherence to ventilation will increase which, in turn, will improve ventilatory failure, quality of life and reduce length of admission during initiation of therapy. We aim to incorporate this technology into routine clinical practice.
The goal of this clinical research study is to compare the effects of sodium bicarbonate to normal saline when used for clearing mucus blockage in patients with airway stents.
The investigators hypothesize that by applying a validated algorithm to accomplish early mobilization in surgical intensive care unit (ICU) patients, these patients will achieve a higher level of mobility which translates to shorter ICU length of stay and improved functional status at discharge. Additionally, the investigators hypothesize that genetic polymorphisms related to muscle strength and sleep will also explain some variance in these outcome variables.
BACKGROUND Many patients in the trauma intensive care unit (TICU) require mechanical ventilation and sedation or anxiolysis. Mechanical ventilation means that a machine is helping a patient breathe if he can't breathe on his own. Because of the mechanical ventilation, these patients also require some medication to help keep them calm. These are called sedatives or anxiolytics. The purpose of this study is to see if acupuncture can lower the amount of sedation and anxiolysis needed by a subject during mechanical ventilation in the TICU. Acupuncture is a medical procedure. Hair-thin sterile needles are inserted at specific points on the body. PROCEDURES Some subjects will get acupuncture and others will get 'fake' acupuncture. By using 'fake' acupuncture, no one other than the acupuncturists will know which group a subject is in. Subjects and the team do not get to pick which subject is in which group. Instead, the groups are picked randomly. Subjects will get real or fake acupuncture twice a day for five days. Standard of care - Both groups will receive the standard of care while in the study. They will be mechanically ventilated and given sedatives and analgesics based on the TICU protocol. Real acupuncture group - This group will receive real acupuncture with real needles. These are stainless steel, one time use, needles. This group will also receive "ear tacks" which are like little needles that can stay on the ear for a few days. The ear tacks will be covered with a bandage so no one can tell which group the subject is in. Sham acupuncture group - This group will receive sham needles. These needles retract into themselves much like a 'magic sword' rather than poking the skin. Subjects in this group will not get ear tacks. In order to hide the group the subject is in, a bandage will be used to cover part of the ear. HYPOTHESIS Real acupuncture will decrease subject's sedation requirements by 30% when compared to the sham acupuncture group.
The purpose of this registry is to retrospectively and prospectively obtain clinical data in consecutively treated patients, in order to demonstrate that the commercially available Edwards SAPIEN Valve with the RF3 delivery system is a safe and effective treatment for patients with pulmonary regurgitation or stenosis.
