Drag and Drop

With ​

Placeholder

ventilation, the anesthetist delivers all of the air required by the patient and the patient does not make spontaneous respiratory effort.

In ​

Placeholder

ventilation, the anesthetist ensures that an increased volume of air and anesthetic gas is delivered to the patient. The patient initiates each inspiration.
