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-breathe).
There is little data to demonstrate which mode of ventilation is better in terms of physiological outcomes and outcome data relating to patient symptoms.
We hypothesize that one type of breathing support: pressure support ventilation would be more comfortable for patients as it more closely matches a patient's own respiratory pattern and and so leads to improved adherence and consequent improvement in quality of life.
Patients with respiratory failure will be randomly assigned to receive either pressure support ventilation or pressure control ventilation for the first 6 weeks and then cross-over to receive the mode not previously used for a further 6 weeks. They will have baseline data recorded and then be followed up after each 6 week block.

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...
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...
Trial to Study Intubation Rates of Non-invasive Ventilation Using Pressure Support Ventilation (PSV) Versus Adaptive Support Ventilation (ASV) Mode in Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease
The clinical course of chronic obstructive pulmonary disease (COPD) is associated with recurrent episodes of exacerbation that results in respiratory failure. The treatment of respiratory ...
Adaptive support ventilation (ASV) is a closed loop ventilation mode that can act both as pressure support (PSV) and pressure controlled (PCV) ventilation. Weaning with ASV shows promising...
The purpose of this research study is to compare difference between breathing by oneself or with the partial help from an anesthesia machine in children under general anesthesia.
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...
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 ...
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...
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...
Previous research has reported that inspiratory muscle weakness is critical to decreased exercise tolerance and exercise tolerance improves with 10 cmH2O pressure support ventilation in patients with ...
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).
Application of positive pressure to the inspiratory phase when the patient has an artificial airway in place and is connected to a ventilator.
A method of mechanical ventilation in which pressure is maintained to increase the volume of gas remaining in the lungs at the end of expiration, thus reducing the shunting of blood through the lungs and improving gas exchange.
Mechanical ventilation delivered to match the patient's efforts in breathing as detected by the interactive ventilation device.

COPD (chronic obstructive pulmonary disease)
COPD (chronic obstructive pulmonary disease) is used for a number of conditions including chronic bronchitis and emphysema, which all lead to the airways in the lungs becoming damaged and thus narrower, making inhalation and exhalation harder...
