The Performance of Dräger Oxylog Ventilators at Simulated Altitude

Abstract: Ventilated patients frequently require transport by air in a hypobaric environment. Previous studies have demonstrated significant changes in the performance of ventilators with changes in cabin pressure (altitude) but no studies have been published on the function of modern ventilators at altitude. This experiment set out to evaluate ventilatory parameters (tidal volume and respiratory rate) of three commonly used transport ventilators (the Drager Oxylog 1000, 2000 and 3000) in a simulated hypobaric environme… Show more

“…The influence of a change in altitude upon different types of ventilators can also differ. Some ventilators provide a lower respiratory frequency, a higher tidal volume, and minute ventilation volume (15, 16), while others do not change significantly (17). This shows that the performance of different ventilators varies when exposed to high altitude.…”

“…Bilevel noninvasive positive-pressure ventilation was the ventilatory mode used for all 20 patients because it is generally considered that there are no differences in clinical outcome between continuous positive airway pressure and bilevel positive airway pressure in COPD. 13,14 We started at a fractional inspired oxygen concentration (Fio 2 ) of 0.5 and subsequently adjusted Fio2 to the minimum required to achieve saturation of 92%. Five minutes after patients had received their treatment, the efficacy of SMT or NIV was evaluated.…”

“…Another common focus in the literature was on airway management and equipment. 12,15,20,26,30,31 Such professional skill differences often define scopes of practice. 3 An emerging area of discussion relates to prehospital therapeutic agents such as muscle relaxants and the carriage of blood products.…”
