The laryngeal mask airway (LMA) is a breathing device that sits above the vocal cords and allows the patient to breathe in and out adequately under general anesthesia (GA). The ProSeal™ LMA (PLMA™) is a specialized type of LMA with a design that permits the delivery of higher pressures to help the patient breathe in and out (ventilate) and also contains a channel to suction the stomach.
Children under GA may breathe through a PLMA in different ways. Spontaneous ventilation consists of the children breathing on their own through a PLMA™. Pressure support ventilation allows the patient to breathe on their own with additional help from the anesthesia machine. Pressure control ventilation allows the patient to breathe with the help of an anesthesia machine.
A child undergoing surgery requires a deep level of general anesthesia which negatively affects their ability to ventilate. Thus, children may not breathe in oxygen and carbon dioxide out adequately at this level of anesthesia and it may be beneficial to provide some level of support to enhance carbon dioxide exchange and to avoid hypoventilation.
This study will attempt to determine whether pressure support ventilation improves ventilation in children undergoing outpatient surgery.

all patients with weaning criteria, spontaneous breathing test will be done. If patient is able to have spontaneous ventilation with maximum of 16 cm of H2O of pressure support, he could b...
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. The...
This study is looking at whether there is a difference in outcomes using two different types of breathing support in those patients who have chronic respiratory failure (patients who under...
This is a prospective randomized cross over study of healthy volunteers undergoing continuous positive airway pressure ventilation via a noninvasive ventilation (NIV) mask with and without...
The purpose of this research study is to compare difference between breathing by oneself or with the partial help from an anesthesia machine in infants under general anesthesia. Hypothesi...
Airway management and ventilation during a tracheobronchial stenting procedure are challenging given that mandatory positive pressure ventilation cannot be fully achieved while using a rigid bronchosc...
Low tidal volume (= tidal volume ≤ 6 mL/kg, predicted body weight) ventilation using volume control benefits patients with acute respiratory distress syndrome. Airway pressure release ventilation ...
Little is known about the best strategy for weaning patients with chronic obstructive pulmonary disease (COPD) from mechanical ventilation. Spontaneous breathing trials (SBT) using a T-piece or pressu...
Airway pressure release ventilation (APRV) maintains a sustained airway pressure over a large proportion of the respiratory cycle, and has a long inspiratory time at high pressure. The purpose of this...
Optimizing pressure support ventilation (PSV) can improve patient-ventilator interaction. We conducted a two-center, randomized cross-over study to determine whether automated PSV lowers asynchrony ra...
Techniques for effecting the transition of the respiratory-failure patient from mechanical ventilation to spontaneous ventilation, while meeting the criteria that tidal volume be above a given threshold (greater than 5 ml/kg), respiratory frequency be below a given count (less than 30 breaths/min), and oxygen partial pressure be above a given threshold (PaO2 greater than 50mm Hg). Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. Present methods include intermittent mandatory ventilation, intermittent positive pressure ventilation, and mandatory minute volume ventilation.
Ventilatory support system using frequencies from 60-900 cycles/min or more. Three types of systems have been distinguished on the basis of rates, volumes, and the system used. They are high frequency positive-pressure ventilation (HFPPV); HIGH-FREQUENCY JET VENTILATION; (HFJV); and high-frequency oscillation (HFO).
Mechanical ventilation delivered to match the patient's efforts in breathing as detected by the interactive ventilation device.
Respiratory support system used primarily with rates of about 100 to 200/min with volumes of from about one to three times predicted anatomic dead space. Used to treat respiratory failure and maintain ventilation under severe circumstances.
Application of positive pressure to the inspiratory phase when the patient has an artificial airway in place and is connected to a ventilator.
An anesthesiologist (US English) or anaesthetist (British English) is a physician trained in anesthesia and perioperative medicine. Anesthesiologists are physicians who provide medical care to patients in a wide variety of (usually acute) situations. ...
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
Anesthesia is the loss of feeling or sensation in all or part of the body. It may result from damage to nerves or can be induced by an anesthetist (a medical professional) using anesthetics such as thiopental or propofol or sevoflurane during a surgical ...
