Lung machine

Lung Machine

A Lung Machine, also known as a Mechanical Ventilator, is a life-supporting device that assists or replaces the function of the lungs. It is primarily used in Intensive Care Units (ICUs) and during surgery when a patient's natural breathing is insufficient or needs to be controlled.

History

The development of the lung machine dates back to the early 20th century. The first successful use of a mechanical ventilator was in 1928 by Dr. Philip Drinker and Louis Agassiz Shaw at Harvard University. The device, known as the Drinker respirator, or more commonly, the "iron lung", was a negative pressure ventilator that encased the patient's body and varied the air pressure to stimulate breathing.

Function

The lung machine works by delivering a controlled volume of oxygen-rich air into the lungs. The machine is connected to the patient through a tube inserted into the trachea. The ventilator then inflates the lungs by creating positive pressure, which forces air into the lungs. The machine then allows the lungs to deflate under their own elasticity, expelling carbon dioxide in the process.

Types of Lung Machines

There are two main types of lung machines: invasive and non-invasive. Invasive ventilation involves the use of a tube inserted into the trachea, while non-invasive ventilation uses a mask or similar device to deliver the air.

Use in Medicine

Lung machines are used in a variety of medical situations. They are most commonly used in ICUs for patients who are critically ill and unable to breathe on their own. They are also used during surgery when the patient is under general anesthesia, as the drugs used can suppress the body's natural urge to breathe. In addition, lung machines are used in the treatment of certain lung diseases, such as Chronic Obstructive Pulmonary Disease (COPD) and Acute Respiratory Distress Syndrome (ARDS).

Risks and Complications

While lung machines are life-saving devices, they are not without risks. Potential complications include lung damage, infections, and negative effects on heart health. Therefore, the use of a lung machine is carefully monitored by medical professionals.
