Ventilator Types. Ventilators for home use are small, lightweight and run on electricity. They can be powered by the internal battery for brief trips outside the home, and can sit on a bedside stand, cart or wheelchair and be used for travel. Most feature various levels of gas/air-flow pressure, volume, rate and duration to control breathing or to wean a patient off the ventilator.
Accumulators usually are installed in hydraulic systems to store energy and to smooth out pulsations. Typically, a hydraulic system with an accumulator can use a smaller pump because the accumulator stores energy from the pump during periods of low demand.here are four principal types of accumulators: the weight-loaded piston type, diaphragm (or bladder) type, spring type, and the hydro-pneumatic piston type. The weight-loaded type was the first used, but is much larger and heavier for its capacity than the modern piston and bladder types.
