Abstract: A ventilator that delivers air at different pressures to a patient during inspiratory and expiratory cycles of breathing and that cycles from inspiratory to expiratory operation when the patient's respiratory flow passes a threshold level. The threshold generally increases form the beginning of inspiration to the end of inspiration. The increase can be linear over all or only a proton of the inspiratory cycle, and the threshold can be adjusted so that cycling is prevented during the initial portion of an inspiratory cycle. The minimum and maximum levels may both be functions of peak flow and the threshold may increase as a function of elapsed inspiratory time. The rate at which the threshold increases from a minimum level to a maximum level may be adjustable for individual patient needs and may be determined from previous breaths.

Abstract: Methods are provided for protecting against ventilation-induced lung injury both directly, by lowering surface tension, and indirectly, by promoting equitable liquid distribution in pulmonary alveolar edema, in which liquid- and air-filled alveoli are normally interspersed. Since a pressure barrier is responsible for trapping liquid in discrete edematous alveoli and the magnitude of the barrier is proportional to surface tension at the air-liquid interface, the present invention provides various methods for promoting equitable redistribution of edema liquid amongst alveoli to help protect the lung during ventilation, including: i) use of an additive that lowers surface tension; ii) use of active, accelerated deflation during mechanical ventilation; and iii) high frequency (>50 Hz) vibration of the lung.

Abstract: The system and method of the present application predicts if there is sufficient CO2 absorbent capacity for the next anesthesia case. If insufficient, the canister can be preemptively replaced when no patient is connected to the breathing system. Such prediction also allows clinicians to determine if the CO2 canister has to be changed during the present case or to wait until the end of the case. In the latter, the clinician may buy time by increasing the fresh gas flow rate to reduce the amount of patient CO2 gases recirculated. A predictive estimation of CO2 breakthrough allows more time to prepare for an orderly CO2 canister replacement during a quiet period in the anesthesia care.

Such changes, or lack thereof, can be based on a backup heart rate or no heart rate at all. Once the threshold voltage is determined where the artificial pacemaker ceases to cause a heartbeat, the voltage of the pacemaker can be set accordingly.

If the patient does require the defibrillation shock, the operator sends a second communication signal delivering the defibrillation shock from the precharged high energy storage capacitor of the ICD. The patient can then be removed from the MRI scanner and the RF and gradient fields of the MRI scanner turned off.
