This notion is totally wrong. Ventilator is an important invention in the field of medical science. ICU cannot be imagined without ventilator. Patients who have breathing problems and are unable to maintain the level of oxygen, needs ventilator the most. It is a lifesaving device and is needed.
During COVID-19 we all have seen that due to lack of oxygen or not maintaining oxygen, patients needed oxygen support via other devices such as BiPAP, NIV, ventilation or else the patient’s condition was worsened or they died. Sometimes, if ventilation is not provided in time, chances of saving lives are reduced.
