Role of Mechanical Ventilation i.e. Invasive Ventilation Critical patients of COVID-19 need shifting to ICU and mechanical ventilation. However, mechanical ventilation is not very easy in terms of infrastructure, availability of ICU beds, maintenance of equipment, man power and experience of operating persons. The risk of contamination due to poor availability of PPEs and inadequate supplies for ICU care, mechanical ventilation remains under objection. Moreover, several healthcare centers around the world do not have access to quality settings. Poor number of available ventilators compels the healthcare providers to line up several patients for each ventilator. This does not give sufficient pressure and volume of oxygen to each patient thus, compromising the quality of mechanical ventilation. Mechanical ventilation has advantages but disadvantages outweigh them. It can worsen the condition of patient by causing barotraumas, volutrauma, atelectrauma, biotrauma and oxytrauma. Mechnaical ventilation is a successful intervention when conducted in commendable infrastructure under experienced operators. It saves lives.
