Putting Covid-19 patients on ventilators could be harming some patients. Health officials are focusing on securing more ventilators to treat coronavirus patients. But many doctors are moving away from using them. Some hospitals have reported high death rates for Covid-19 patients on ventilators and some doctors worry that the machines could be putting some patients at risk. Ventilators exert pressure on the lungs, which many elderly patients can’t handle.
Using ventilators involves sedating a patient and sticking a tube into the throat, in general, 40% to 50% of patients with severe respiratory distress die while on ventilators 80% of coronavirus patients placed on the machines in New York have died. Similarly, the UK reported thzt 66% pf patients plced on machines have died. Some patients are becoming completely dependent on them to breathe.
Ventilators are complex machines and require experience to operate as the amount of airflow and pressure can be different for each. Some doctors think that ventilators are being overused even for those who don’t need them. Experts say that patients with bacterial pneumonia may be on a ventilator for 1 or 3 days.
Coronavirus patients are placed on a ventilator for up to 15 days and this is one of the reasons why ventilators could grow in short supply. Instead, they recommend the use of oxygen therapy as well. This doesn’t mean ventilators are useless, it just means other options should also be considered depending on the needs and conditions of each patient. Some experts speculate that ventilators might ignite a harmful immune system reaction. Medical ventilation may also worsen lung injury. The dangers of ventilators can be reduced by limiting the amount of pressure and the sixe of breaths provided by the machine
