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.
Ventricular tachyarrhythmias are a group of arrhythmias that result in a heartbeat greater than 100 beats per minute and originate anywhere in the ventricle. There are three main types of ventricular tachyarrhythmias: ventricular fibrillation, monomorphic ventricular tachycardia, and polymorphic ventricular tachycardia. Each one is associated with a high mortality rate. Symptoms include chest pain, palpations, hemodynamic collapse, and end-organ damage.
