What is considered long term ventilator use

Prolonged mechanical ventilation (PMV) is defined by the Centers for Medicare and Medicaid Services in the United States as greater than 21 days of mechanical ventilation for at least six hours per day [1], although many studies have used an alternative duration to define PMV.

How long a patient can be kept on ventilator?

Can you be on a ventilator longer than 14 days?

When should a patient be removed from a ventilator?

Although 24–48 h of unassisted breathing often is considered to define the successful discontinuation of ventilator support in the ICU setting, many studies use shorter time periods to indicate success and often do not report subsequent reintubation rates or the need to reinstitute mechanical ventilatory support.
