Pulmonary function was measured invasively in a subset of rats 7 days after treatment with DA (n = 8) or vehicle (n = 4) using the FlexiVent mechanical ventilator and data acquisition system (SCIREQ, Montreal, PQ, Canada).
Ptrach, Pes and gas flow were measured and recorded by a computerized system incorporated into the mechanical ventilator (AVEA™, Cardinal Healthcare, Dublin, OH, USA).
This process can also occur automatically, through the so-called closed-loop ventilation system, when this software is integrated with a mechanical ventilator.
Information about Dräger Babylog 8000plus conventional mechanical ventilator, Carefusion SensorMedics high-frequency oscillatory ventilator, and Viasys Infant Flow system continuous positive airway pressure (CPAP) was collected (see Table 2).
The patients were ventilated with a Servo 300 C mechanical ventilator (Siemens) using a standard ventilator circuit.
Patient valves are used for positive pressure ventilation with a BVM or a mechanical ventilator [ 12].
Cavaliere and colleagues described a noise level of 94 ± 2 dBA when using the helmet with a CPAP system compared with 57 ± 11 dBA for a mechanical ventilator plus mask [ 29].
Our objective was to compare mechanical ventilator weaning duration for critically ill adults and children when managed with automated systems versus non-automated strategies.
A co axial tubing system was connected (Universal F2 breathing circuit, Medical product service GmbH, Braunfis, Germany) to a mechanical ventilator (Galileo ventilator, Hamilton, Bonaduz, Switzerland or Servo ventilator, Maquet, Rastatt, Germany) and a heat moist exchanger (HME, Medisize, Hillegom, the Netherlands) was placed at the end as part of routine practice.
In this work we propose a chemical sensing system based on an array of 16 metal-oxide gas sensors that we combined with an external mechanical ventilator to simulate the biological respiration cycle.
