Abstract: The present invention includes a method for treating a patient in need of facilitated oxygen delivery through the lungs, additional lung surfactant, removal of material from inside the lung, or inflation of collapsed portions of the lung, comprising the step of introducing into the lung of the patient an effective therapeutic amount of a fluorocarbon liquid, the amount not exceeding the functional residual capacity of the lung of the patient upon exhalation taking into account any positive and expiratory pressure applied to the patient's lung. The method may also comprise the additional step of providing an oxygen-containing breathing gas to the patient while the fluorocarbon liquid is in the lung.

Abstract: Systems and methods are described for calculating, in real-time, various oxygenation parameters including total oxygen transport, mixed venous blood oxygen tension and mixed venous blood oxyhemoglobin saturation in a patient. The system preferably uses a computer, an arterial pressure line and a blood chemistry monitor to assist a physician in accurately determining when to give a patient a blood transfusion or otherwise alter the clinical management of that patient.

Abstract: A system and method is described for determining and graphically displaying oxygenation states of a patient in real time. The system is non-invasive and can display information to a physician that is intuitive. Various display objects are described for illustrating the output of oxygenation values. The display objects reflect the in vivo physiology that they measure, thus making interpretation of the measured values very intuitive.

Abstract: 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.

Abstract: A method for treating conditions associated with ischemia or infarct is disclosed which includes the steps of administering a biocompatible non-blood oxygen carrier while monitoring one or more oxygenation indices to maintain oxygenation of the patient's tissues at or above a predetermined level.

Abstract: A method for hemodiluting a patient is disclosed which includes the steps of administering a biocompatible oxygen carrier in conjunction with surgery or organ ischemia or infarct while assessing the patient's PvO.sub.2 or other oxygenation indices, and administering to the patient additional oxygen carrier or autologous blood in response to the PvO.sub.2 value if necessary to maintain the PvO.sub.2 at or above the desired level.
