A Mechanical Repilator: A Description Of Mechanical Vilators

MECHANICAL VENTILATORS DECEMBER 10th, 2017

A ventilator is a mechanical device that is designed to aid the body in moving gas in and out of the lungs. Breathing, the process of moving air into and out of the lungs, and can be also called as ventilation. The process of breathing includes, inhaling certain amount of volume through the mouth or nose and moving into the pharynx, trachea and bronchi respectively, During inspiration, The diaphragm contracts by moving downwards that helps to increase the chest cavity space which helps the lungs to expand. During expiration, the diaphragm relaxes decreasing the chest cavity space to aid the lungs in expiration. In the alveoli, it exchanges with the carbon dioxide rich blood with fresh oxygen. This process is carried out multiple time in a minute, with a frequency of 12 beats/min when at rest and increases accordingly with exercise or various emotional states.

The lungs helps primarily to exchange gases, the carbon dioxide byproduct produced from the body with the fresh oxygen

It consists of a syringe pump that is fitted to the person’s nose or mouth with a mask. This causes the air to flow from the device to the person’s lungs when the device is compressed and out of the lungs when the device is stretched. Automatic ventilation is widely used as it does not require operator intervention. The patient Interface for these automated ventilators can be categorized into two pressure ventilators, positive pressure ventilators and negative pressure ventilators. The positive ventilator circuit can have one or two breathing tubes. The ventilator circuits can either be tracheostomy tube into the subject’s throat, or a mask that covers the patient’s mouth and nose. Negative pressure ventilators are a type of ventilators that have patient enclose just their rib cage and abdomen or might have their whole body enclosed except your head
