Filter by:Measuring hemodynamic parameters in ventilated patients is important yet still complicated to perform. Inert gas rebreathing (IGR) showed promising results when being compared to other invasive as well as non-invasive techniques for the measurement of cardiac output. The aim of our study is to evaluate the feasibility of IGR in ventilated patients.
Background: Patients in the intensive care unit (ICU) are the sickest in hospital, and need advanced life-support. Survivors of critical illness are very vulnerable to weakness and disability. Up to 1 in 4 have severe leg weakness impairing their quality of life for as long as 5 years after ICU discharge. In-bed cycling employs special equipment that attaches to a patient's hospital bed, allowing them gentle leg exercise while in the ICU. The investigators will offer patients in-bed cycling while they are needing a breathing machine, to help them recover from weakness as fast as possible. Before doing a larger trial testing if in-bed cycling reduces disability, data on safety (Is it safe?) and feasibility (Can the investigators do it?) are needed. Objectives: To study the safety and feasibility of in-bed leg cycling in critically ill patients who need breathing machines. Methods: Adult patients admitted to the ICU who need a breathing machine and are expected to survive their ICU stay are eligible. Specially trained physiotherapists will provide patients with 30 minutes of in-bed cycling each day while they are in the ICU. Outcomes: The investigators will study (1) Safety: the heart rate and breathing patterns of patients doing in-bed cycling, while carefully monitoring for safety. (2) Feasibility: whether patients can cycle on most days of their ICU stay, whether patients and their families agree to be a part of the study, and whether the investigators can assess patients' strength in the ICU and at hospital discharge. Relevance: As the Canadian population ages, the demand for breathing machines during acute illness will increase dramatically. Effective methods of physiotherapy are needed for critically ill patients to minimize muscle weakness, speed recovery, and improve quality of life. This pilot study is the first of several future larger studies about in-bed cycling in the ICU. This program of research will help patients needing life support to regain their strength and recover as fast as possible from critical illness.
The purpose of this study was : - to determine the effect of inhaled antibiotics on airway bacteria in ventilated patients - to determine the effect of inhaled antibiotics on respiratory infection
The US EPA Clean Air Multiyear research program is moving toward a multi-pollutant approach to the assessment of air pollution in response to recommendations by the NRC 2004 and the BOSC in 2005. Such an approach better reflects the complexity of real-world air pollution problems and parallels evolving scientific and regulatory considerations. Ozone (O3) and diesel exhaust (DE) generally are major and important components of ambient air pollution. This proposed study will address the agency's goals by investigating the cardiopulmonary health effects in healthy human subjects co-exposed to O3 and DE. The findings derived from these exposures will provide NCEA findings for risk assessments of O3 and DE, as well as the Office of Air and Radiation (includes OTAQ and OAQPS) with information relevant to possible modulation of PM-induced health effects and responses by a gaseous co-pollutant for potential standard setting. Additionally the findings will address the fundamental driving principle of the Clean Air Research strategy related to reduction of health due to air pollutant exposures.
It is hypothesized that the use of Neurally Adjusted Ventilatory Assist (NAVA) compared to pressure support to provide noninvasive ventilation to children will result in a decrease in the number of children with moderate to severe respiratory failure failing noninvasive ventilation and requiring endotracheal intubation. It is further hypothesized that noninvasive ventilation with NAVA compared to pressure support will result in a decrease in the length of mechanical ventilation, and the length of PICU and hospital stay.
This pilot study will be an observational no randomize study in which the NiNAVAped protocol will be applied solely to the NIV NAVA arm.
Bronchoscopy with broncho-alveolar lavage is a diagnostic tool in patients with pneumonia. Especially patients with acute or chronic pulmonary diseases are at risk of respiratory failure during or after bronchoscopy. It is known that in these cases bronchoscopy can be performed safely using non-invasive ventilation. It seems probable that high-flow oxygen, which is used in the treatment of patients with hypoxemic respiratory failure, is equally effective in preventing the development of respiratory failure during fiberoptic bronchoscopy while improving patient comfort. In this prospective randomised study the safety of high-flow oxygen is compared with non-invasive ventilation in patients with hypoxemic respiratory failure undergoing fiberoptic bronchoscopy.
Knowledge-based systems were initially developped to automatically adapt pressure support settings during invasive ventilation, and proved to be at least as efficient as experienced clinicians. Non-invasive ventilation has become the standard of care for patients suffering from acute hypercapnic respiratory failure (ARF)and has reduced the need for endotracheal intubation in these patients, thus reducing their hospital mortality. NIV success or failure is closely related to the tolerance of NIV treatment, which is tightly correlated to patient-ventilator synchrony. As severe asynchronies frequently occurs during NIV (namely in more than 40% of patients) and as the occurence of asynchronies is related to the use of high pressure support levels, to the presence of leaks and/or to non optimal expiratory trigger settings, very frequent ventilator settings adaptations should allow reducing patient-ventilator asynchronies but require the presence of an experienced clinician at the bedside during NIV treatment. A computer-driven ventilator settings adaptation has the adavantage of permitting very frequent ventilator settings adaptation whithout requiring the presence of an experienced clinician at the bedside and could possibly improve patient-ventilator interaction. The aim of the present study is to test the faisability of using the Smartcare NIV computer-driven system to automatically adapt ventilator settings during non invasive ventilation delivered because of acute respiratory failure.
Safer Births is a research and development collaboration to establish new knowledge and new innovative products to better equip and increase competence of health workers for safer births and increased newborn survival worldwide. The main objectives are: To randomize different devices for fetal heart rate assessments. To assess if a novel Newborn Resuscitation Monitor will facilitate newborn resuscitation in a low-resource setting. To determine bag mask ventilation treatment and devices beneficial for neonatal outcome.
Opioids are the mainstay of analgesia in hospitalized children but opioid therapy is associated with life-threatening respiratory depression requiring antagonism with naloxone. Hence, it is hypothesized that naloxone requirement can be used as a quality measure of opioid safety. A retrospective medical chart review of 95 patients, who received naloxone for life threatening events, from June 2006-2012, is planned, to identify significant factors associated with risk for opioid induced respiratory depression and formulation of preventive strategies.
