Filter by:The aim of this study is to evaluate the effects of the sedatives propofol and midazolam on stress response and immune function in critically ill patients with alcohol use disorders who are undergoing mechanical ventilation.
During weaning from mechanical ventilation process, the energy expenditure in T tube is greater than pressure support ventilation.
In this study, we want to compare two different kinds of artificial ventilation to see if one encourages faster weaning from breathing support and if one provides better sleep quality. These artificial ventilation types are: 1. Pressure support ventilation; the standard ventilation that we use for the patients in the Respiratory Acute Care Unit. Pressure support ventilation ventilators use constant air pressure to assist patients with their breathing. 2. Proportional assist ventilation; a newer way of helping people with their breathing. The air pressure provided by proportional assist ventilation ventilators varies with the size of the breath that a person takes.
Sedation is widely used in mechanically ventilated patients. Propofol, benzodiazepines and opioids are the most used drugs. The study hypothesis is that sedation with remifentanil (an opioid drug) could improved respiratory pattern and effort in mechanically ventilated patients with rapid shallow breathing or high respiratory rate.
The purpose of this study is to evaluate the use of the VersaMed iVent ventilator in the acute care setting, hypothesizing that, in comparison to the standard approach, the use of the VersaMed will facilitate transport and reduce transport-associated complications while providing equivalent ventilatory support and transport success rates for both intubated patients and patients receiving noninvasive ventilation.
The purpose of this study is to monitor sleep in patients using breathing machines, because little is known about sleep when patients use masks to help their breathing. We'd like to compare sleep in patients using masks to that in patients with a tube in their throats.
This study is a prospective, observational case series of a convenience sample of mechanically ventilated pediatric patients in the Pediatric ICU, Progressive Care Unit and Operating Room at the Children's Hospital of Philadelphia. We propose to observe, measure and report the accuracy, precision and bias of defibrillator electrode pads to detect breathing in stable but critically ill and mechanically ventilated children. This study will provide preliminary data to inform the resuscitation research community and assist development of evidence-based pediatric resuscitation guidelines in the future.
This protocol is a prospective, pilot, observational study in the Pediatric Intensive Care Unit (PICU), Progressive Care Unit (PCU) and the Operating Room (OR) settings at the Children's Hospital of Philadelphia (CHOP). We propose to observe, measure and report the effect of incremental gentle sternal pressure increases on intrathoracic pressure, and other surrogates of hemodynamic function, in stable mechanically ventilated children. This study will provide preliminary data to inform the resuscitation research community and assist development of evidence-based pediatric resuscitation guidelines in the future.
Neurally Adjusted Ventilatory Assist (NAVA) is a new mode of mechanical ventilation that is controlled by the electrical activity of the diaphragm (EAdi). The EAdi is a signal that represents the patient's breathing effort, and hence with NAVA, the assist being delivered is synchronized and proportional to the demands of the patient. This is a prospective physiological study of the feasibility of NAVA ventilation over 24 hours. The aim is to demonstrate that NAVA can maintain spontaneous breathing and unload the respiratory muscles during both sleep and wake cycles over a 24 hour period.
The present protocol will demonstrate the feasibility and efficacy of a newly developed mode of mechanical ventilation, Neurally Adjusted Ventilatory Assist, commonly known as NAVA. During NAVA, the timing and magnitude of pressure delivered are controlled by the infants' diaphragm electrical activity (EAdi), a validated measurement of neural respiratory drive. Recent clinical trials in adults and term infants have shown that NAVA is more synchronous than conventional pressure support ventilation, and that NAVA delivers lower mean airway pressures to achieve the same ventilation and respiratory muscle unloading. NAVA has recently been approved for use in neonates by Health Canada and the FDA in the United States, and is commercially available on the Servoi ventilator (Maquet Critical Care, Solna, Sweden). The present protocol is designed as a "case study" where the researchers responsible would like to evaluate the feasibility and efficacy of ventilating a premature baby on NAVA with the Servoi for 12 hours.
