Methods and apparatus are provided which allow for closed-circuit ventilation for the treatment or diagnosis of disorders. The closed-circuit ventilation apparatus of the present invention provide a closed-circuit respirator that isolates the gas flow path from the ventilator apparatus. This allows the prolonged administration of expensive materials such as fluorochemicals without excessive loss due to evaporation. As such the provided methods an apparatus are particularly applicable to liquid ventilation including partial liquid ventilation and total liquid ventilation.

[ What is claimed is:] [1.] A process for closed-circuit partial liquid ventilation therapy comprising the steps of:introducing at least one non-anesthetic gas or vapor into pulmonary air passages of a respiring patient;capturing expiratory gas from said patient in a closed-circuit respirator in fluid-conducting communication with said pulmonary air passages, said expiratory gas comprising carbon dioxide and at least a portion of said introduced gas or vapor;circulating said expiratory gas through a gas flow path defined by said closed-circuit respirator wherein at least a portion of said carbon dioxide is removed; andthereafter reintroducing at least a portion of the circulated expiratory gas comprising said introduced gas or vapor into the pulmonary air passages of the patient.
