But health officials have wondered whether ventilators might be making the situationworse in some patients.

Experts say ventilators can be damaging to a patient because of the pressure on the lungs as the oxygen is forced in over time.

He said those decisions are separate from worries that there are not enough ventilators in the United States.
他表示，這些決定與擔心美國沒有足夠的呼吸機無關。
That is also a worry, Habboushe added.
哈布希補充道，後者也是一個擔憂。
There are reports that coronavirus patients are usually on ventilators much longer than other patients, said Dr. William Schaffner.

Coronavirus patients use ventilators for up to 15 days, and they are dying.
