Ventilators are highly sought after and hard to find – but they are not always successful. Here's how they work:

How do ventilators help patients breathe?A popular mode used with ventilators is called assist-control . In that mode, the ventilator assists with breathing. It's ideal for recovery because the patient only has to initiate a breath and the ventilator does the rest.

Even if the patient attempts a breath in between the timed breaths, the ventilator will take over and deliver the same volume of air as the timed breath.Patients are connected to ventilators in three ways. Though patients are sedated for the invasive procedures, the process of putting tubes in patients can be dangerous for health care workers, who risk being infected themselves. There's also a risk of infection for patients with breathing tubes.

Once the tube is inserted, a cuff is inflated to keep the tube in place and seal out secretions. The laryngoscope is removed and the tube is taped to the side of the face. The tube is checked to make sure it can equally inflate both lungs.This is a more invasive procedure with an incision in the windpipe for insertion of a tracheal tube.

As a physician I can tell you right now this article has false info. Typical of usatoday. There is no ventilator being connected to a patient by a mask. A vent is always connected by an ET tube. Whoever wrote this probably meant a bipap or cpap machine. Idiots!

How disgusting...you fearmongering rags are about bankrupt right?!? FakeNews WalkAway

Correction: Why a small .1% of coronavirus patients who land in a hospital need a ventilator. The 99.9%+ of people infected with coronavirus are not even noticing they are infected because their symptoms are so mild to non-existent.

Literally a last gasp device! Only around 20% survival rate for Covid-19 patients! Not good to get sent to ICU and get last rights before you’re put on a ventilator. Scary very scary!
