MECHANICAL VENTILATORS Meaning and
Definition
-
Mechanical ventilators, also known as respirators or ventilatory support systems, are medical devices used to assist or replace the natural function of breathing in patients who cannot breathe adequately on their own. These devices are commonly utilized in critical care settings such as intensive care units (ICUs) and emergency departments to provide life-sustaining support to individuals with respiratory failure or insufficiency.
Mechanical ventilators work by delivering a carefully controlled mixture of air and oxygen into the patient's lungs, while removing carbon dioxide from the body. They consist of a variety of components, including a gas source (usually compressed air or oxygen), a control system to regulate airflow and pressure, tubing or circuitry to deliver the air and oxygen to the patient's airways, and a patient interface such as an endotracheal tube, tracheostomy tube, or face mask.
The ventilator's control system allows healthcare professionals to adjust various parameters such as tidal volume (the amount of air delivered with each breath), respiratory rate (the number of breaths delivered per minute), and positive end-expiratory pressure (PEEP - a constant pressure applied to the airways to enhance oxygenation and prevent lung collapse).
Mechanical ventilators are commonly used for patients facing acute respiratory distress syndrome (ARDS), severe pneumonia, respiratory failure due to chronic obstructive pulmonary disease (COPD), and other conditions where the patient's ability to breathe independently is compromised. These devices provide vital support to stabilize patients, alleviate breathing difficulties, and help promote improved gas exchange until the underlying condition is addressed or resolved.

Etymology of MECHANICAL VENTILATORS
The word "mechanical" comes from the Latin word "mechanicus", which means "of machines". It is derived from the Greek word "mekhane", meaning "machine" or "contrivance". The term "ventilator" originates from the Latin word "ventilare", meaning "to fan" or "to provide with fresh air". The combination of these two words describes a device that is pneumatic or electronically powered to assist or replace the natural ventilation functions of the human respiratory system.
