BACKGROUND Prolonged mechanical ventilation, longer hospital stay, and a lower rate of home discharge have been reported with patient-ventilator asynchrony in medical patients. Though commonly encountered, asynchrony is poorly defined within the traumatically injured population. METHODS Mechanically ventilated trauma patients at an urban, level-1 center were enrolled. Breath waveforms were re...

Newborn infants may have a high oxygen cost of breathing (OCB) at the time of being weaned from mechanical ventilation. We hypothesized that this increase in oxygen consumption (V'O2) could be reduced by using certain weaning ventilatory modes. We designed a study to assess V'O2 during three weaning ventilatory modes: patient triggered ventilation, synchronous intermittent mandatory ventilation...

OBJECTIVE To study the effectiveness of high-frequency ventilation (HFV) for the treatment of pediatric patients with acute severe respiratory failure. DESIGN Post hoc analysis of retrospectively and prospectively acquired data. SETTING Tertiary pediatric ICU. SUBJECTS Twelve patients, ages 4 months to 15 years, who developed acute severe respiratory failure from diverse causes. INTERVE...

background: patients undergone mechanical ventilation need rapid and reliable evaluation of their respiratory status. monitoring of end-tidal carbon dioxide (etco2) as a surrogate, noninvasive measurement of arterial carbon dioxide (paco2) is one of the methods used for this purpose in intubated patients. objectives: the aim of the present trial was to study the relationship between end-tidal c...

Lung-sparing medical ventilation –CPAP + PSV Mode – The FABIAN HFO is a new medical ventilator that was developed mainly for use with newborns and can accommodate children weighing up to 30 kg. It is equipped for ventilation modes CMV, SIMV, AC, PSV, and HFO and has VG, volume limit, and leak correction functions. A key feature is separate pressure setup for backup ventilation during apnoea in ...

OBJECTIVES To review the arterial carbon dioxide tensions (PaCO(2)) in newborn infants ventilated using synchronized intermittent mandatory ventilation (SIMV) in volume guarantee mode (using the Dräger Babylog 8000+) with a unit policy targeting tidal volumes of approximately 4 mL/kg. METHODS Data on ventilator settings and arterial PaCO(2) levels were collected on all arterial blood gases (A...

BACKGROUND In pressure-controlled (PC) ventilation, tidal volume (V T) and transpulmonary pressure (P L ) result from the addition of ventilator pressure and the patient's inspiratory effort. PC modes can be classified into fully, partially, and non-synchronized modes, and the degree of synchronization may result in different V T and P L despite identical ventilator settings. This study assesse...
