introduction chronic obstructive pulmonary disease (copd) is a chronic disorder with many systematic complications and one of the most important reasons for patients to require mechanical ventilation, admission in intensive care unit and prolonged mechanical ventilation. although the first attempt in separation of mechanical ventilation is failed in half of chronic obstructive pulmonary disease...
BACKGROUND Adaptive support ventilation (ASV) facilitates ventilator liberation in postoperative patients in surgical intensive care units (ICU). Whether ASV has similar benefits in patients with acute respiratory failure is unclear. METHODS We conducted a pilot study in a medical ICU that manages approximately 600 mechanically ventilated patients a year. The ICU has one respiratory therapist...
BACKGROUND Volume-controlled ventilation has been suggested to optimize lung deposition during nebulization although promoting spontaneous ventilation is targeted to avoid ventilator-induced diaphragmatic dysfunction. Comparing topographic aerosol lung deposition during volume-controlled ventilation and spontaneous ventilation in pressure support has never been performed. The aim of this study ...
Hence, there is a need for the ventilator, in general, to provide for both spontaneous and mandatory breaths on an intermittent basis. This was the motivation for inventing IMV in the first place, as Kacmarek and Branson mentioned in their paper.1 How does recognition of only type 1 IMV (as in the article by Kacmarek and Branson1) impair our understanding of modes? There are only 3 basic goals ...
BACKGROUND Adaptive support ventilation (ASV) is a closed loop mode of mechanical ventilation (MV) that provides a target minute ventilation by automatically adapting inspiratory pressure and respiratory rate with the minimum work of breathing on the part of the patient. The aim of this study was to determine the effect of ASV on total MV duration when compared with pressure assist/control vent...
OBJECTIVES To understand the role of patient-ventilator asynchrony in the etiology of sleep disruption and determine whether optimizing patient-ventilator interactions by using proportional assist ventilation improves sleep. DESIGN Randomized crossover clinical trial. SETTING A tertiary university medical-surgical intensive care unit. PATIENTS Thirteen patients during weaning from mechani...
Introduction Pressure-support ventilation improves lung mechanics, blood gas exchange, hemodynamics, and work of breathing (WOB) in mild acute respiratory distress syndrome (ARDS) [1,2]. Nevertheless, those beneficial effects could be dependent of positive end-expiratory pressure (PEEP) applied during mechanical ventilation. So far, no study has compared pressure-support ventilation (PSV) with ...
The mode of ventilation used during awake extubation has not previously been studied. We conducted a randomised controlled trial comparing spontaneous respiration, intermittent positive pressure ventilation, and pressure support ventilation (each n = 13) for incidence and severity of peri-extubation complications following routine elective surgery. We found the severity of peri-extubation cough...
