what is ventilation medical

A medical ventilator, also known simply as a ventilator, is a machine that helps a person breathe by pumping air into the lungs. It is commonly used in situations where a person is unable to breathe adequately on their own, such as during surgery, in cases of respiratory failure, or in severe COVID-19 symptoms. Ventilators can be life-saving devices, as they provide support for the respiratory system by delivering oxygen and removing carbon dioxide from the body. The machine uses positive pressure to force air into the lungs, essentially acting as an external set of lungs. Ventilators are crucial in intensive care units for patients who cannot breathe on their own and can be adjusted to meet specific needs. They are used to keep the airways open, deliver oxygen, and remove carbon dioxide, thereby supporting the patients lung functions. Ventilators play a critical role in stabilizing patients while other treatments and medications help the body recover. Different types of ventilators are available, and the type used depends on the individuals condition. Ventilators are regulated by healthcare professionals, such as doctors and respiratory therapists, who set the controls for pressure, humidity, volume, and temperature of the air. While ventilators can be life-saving, they are not without risks, and prolonged use may lead to complications such as damage to the vocal cords, trachea, or lungs. Overall, a medical ventilator is a vital tool in medical care, providing essential support for individuals who are unable to breathe adequately on their own.
