The US is running short on ventilators amid the coronavirus pandemic. Here's how they work and why they're so important.
About 1 million Americans might need a ventilator during the coronavirus outbreak, from Dr. James Lawler, an infectious diseases specialist and public health expert at the University of Nebraska Medical Center. Lawler's projections didn't include a time frame, and all of those people might not need a ventilator at the same time.Some patients with COVID-19 have reported shortness of breath and trouble breathing.
The second kind, called hypoxemic respiratory failure, is when not enough oxygen is entering someone's bloodstream. This sort of failure is often caused by infections like pneumonia, which can cause damage to the lungs. The coronavirus is also shown to cause such damage. "We treat that by giving higher fractions of oxygen," Hill said. "We can give you 100% oxygen to get your oxygen levels in the blood up, but we have to be careful because that 100% oxygen could be damaging too."In New York, the state with the most reported COVID-19 patients in the country, there are still enough ventilators to sustain the fewer than 800 coronavirus patients who currently need to be on the machines, Gov. Cuomo said at a press conference on Tuesday morning.
if things get worse. That could be risky for patients since ventilators are usually built to help just one person at a time. If ventilators are shared among two patients, they would each need to have similar lung capacities and body sizes for things to go smoothly.
