How Does Medical Portable Ventilator Work?

Portable ventilation takes place either by volume- or pressure-controlled modes. Volume-controlled versions are designed to achieve a programmed tidal volume with each ventilation at the appropriate pressure within a safe limit for the patient. Conversely, pressure-controlled modes deliver ventilations until a set pressure is reached, with tidal volume regulated by both lung compliance and airway resistance.

Controlled ventilation occurs when everything associated with respiration technically is managed by the rescue or care team. It requires a dose of respiratory gas specifically calibrated for the patient's age, weight, size, and particular condition--which is best accomplished through the use of a portable ventilator machine. The device is lightweight, easy to operate, and combines the functionality of an ICU-grade ventilator with the compactness and ruggedness befitting an EMS transport ventilator.
