BACKGROUND With adaptive support ventilation, respiratory rate and tidal volume (V(T)) are a function of the Otis least work of breathing formula. We hypothesized that adaptive support ventilation in an open lung ventilator strategy would deliver higher V(T)s to patients with acute lung injury. METHODS Patients with acute lung injury were ventilated according to a local guideline advising the...

INTRODUCTION The present study is a pilot prospective safety evaluation of a new closed loop computerised protocol on ventilation and oxygenation in stable, spontaneously breathing children weighing more than 7 kg, during the weaning phase of mechanical ventilation. METHODS Mechanically ventilated children ready to start the weaning process were ventilated for five periods of 60 minutes in th...

Positive airway pressure (PAP) is considered first-line therapy for moderate to severe obstructive sleep apnea and may also be considered for mild obstructive sleep apnea, particularly if it is symptomatic or there are concomitant cardiovascular disorders. Continuous PAP is most commonly used. Other modes, such as bilevel airway pressure, autotitrating positive airway pressure, average volume a...

introduction: purpose of this study was the effect of different music rhythms (fast rhythm and slow rhythm) in physiological responses of health young male after an exhaustive exercise session during primary minutes of recovery period. methods: seventeen healthy male (ages: 19.76 ± 0.97 yr, height: 176 ± 6.72 cm, weight: 68.5 ±7 5.95 kg), voluntarily performed bruce protocol until exhaustion wi...

Pressure controlled ventilation is a common mode of ventilation used to manage both adult and pediatric populations. However, there is very little evidence that distinguishes the efficacy of pressure controlled ventilation over that of volume controlled ventilation in the adult population. This gap in the literature may be due to the absence of a consistent and systematic algorithm for managing...

Background: Previous studies have shown that progesterone increases the ventilatory performance in healthy individuals and in patients with chronic obstructive pulmonary disorders. The study was designed to investigate the effect of a single intramuscular administration of progesterone on ventilatory performance in adult trauma patients during partial support mechanical ventilation. Methods: Fo...

BACKGROUND Prolonged controlled mechanical ventilation depresses diaphragmatic efficiency. Assisted modes of ventilation should improve it. We assessed the impact of pressure support ventilation versus neurally adjusted ventilator assist on diaphragmatic efficiency. METHOD Patients previously ventilated with controlled mechanical ventilation for 72 hours or more were randomized to be ventilat...
