Ventilators

A ventilator is a medical device designed to assist patients in maintaining normal respiratory function, particularly when they are experiencing breathing difficulties or respiratory failure. Ventilators mechanically deliver oxygen while expelling carbon dioxide, ensuring patients receive adequate oxygen supply. The basic operating principle of a ventilator involves providing positive pressure to facilitate airflow into the lungs. Various parameters, such as respiratory rate, tidal volume (the volume of gas inhaled or exhaled during each breath), and oxygen concentration, can be adjusted to meet the specific needs of different patients. Ventilators are vital medical devices widely employed in the treatment of various respiratory conditions.
