results sixty patients were involved in this study. in asv mode, values including peak airway pressure (p-peak), end-tidal carbon dioxide (etco2), tidal volume and respiratory dead space were significantly lower than simv mode. although the mean value for dynamic compliance had no significant difference in the two types of ventilation, it was better in asv mode. methods in a crossover study, pa...

RATIONALE Amyotrophic lateral sclerosis (ALS) is a rapidly progressing neurodegenerative disease that involves limb, axial, bulbar, and respiratory muscles. Fatigue and weakness of the respiratory muscles eventually induce respiratory insufficiency, which is one of the main causes of death in patients with ALS. In ALS patients with respiratory insufficiency, application of a ventilator is indis...

Background: Heated humidified high-flow nasal cannula (HHHFNC) is gaining popularity in the management of respiratory distress in preterm neonates. However, it is not known whether it takes precedence over the gold standard nasal continuous positive airway pressure (NCPAP) in this age group as a primary mode of non-invasive ventilation (NIV). There is limited evidence ...

BACKGROUND Various modes of mechanical ventilation have different effects on respiratory variables. Lack of patients' neuro-ventilatory coordination and increasing the work of breathing are major disadvantages in mechanically ventilated patients. OBJECTIVES This study is conducted to compare the respiratory parameters differences in Adaptive support ventilation (ASV) and synchronized intermit...

STUDY OBJECTIVE To compare the effects of noninvasive assist-control ventilation (ACV) and pressure support ventilation (PSV) by nasal mask on respiratory physiologic parameters and comfort in acute hypercapnic respiratory failure (AHRF). DESIGN A prospective randomized study. SETTING A medical ICU. PATIENTS AND INTERVENTIONS Fifteen patients with COPD and AHRF were consecutively and rand...

abstract background: different modes of mechanical ventilation are used for respiratory support after coronary artery bypass graft (cabg). this study aimed to compare the effect(s) of using adaptive support ventilation (asv) and synchronized intermittent mandatory ventilation (simv) on the length of mechanical ventilation (intubation duration) and hospital stay after coronary artery bypass graf...
