Abstract: The invention features an exhalation assist device for adjusting the airway resistance in an exhalation circuit of a medical ventilator. The device includes a set of pressure, airflow and airway sensors, a controlling processor, a user interface, and a ventilatory unit in communication with a medical ventilator. Data relating to pressure within the ventilatory unit and data relating to exhalation airflow, exhalation circuit pressure and exhalation circuit resistance are provided to the controlling processor by the sensors. The controlling processor compares measured and calculated values for airway pressure, airflow, airway resistance and applied negative pressure with desired values that have been entered by a clinician. Based on these calculations, the controlling processor transmits a signal that will change the applied negative pressure applied to the exhalation circuit by the ventilatory unit.

Abstract: A ventilator control system controls a ventilator pneumatic system in a medical ventilator. The ventilator control system includes a user interface, a memory and a processor. The user interface receives input values from a user for setting one or more breath parameters within a set of breath parameters. The user interface can include a display for displaying the status of the patient's pulmonary system and the set of breath parameters. The memory stores the set of breath parameters after the user has set one or more breath parameters to desired input values. The processor simultaneously adjusts a plurality of controls within a ventilator pneumatic system in response to the set of breath parameters. The user can change or implement new phases, breaths, modes or therapies in seconds such that the therapy delivered to the patient is essentially uninterrupted. Also, a simulator may be provided for predicting the status of the patient's pulmonary system prior to adjusting the plurality of controls.

Abstract: A pneumatic system is provided for a ventilator is provided for controlling inspired and expired patient gas flow during respiratory therapy. The pneumatic system includes a pneumatic circuit for controlling a supply of one or more selected gases to a patient and a disposable patient breathing circuit for isolating exhaled patient gasses from the pneumatic circuit. The pneumatic circuit includes a dual venturi for assisting compression and expansion of a flexible gas reservoir of the patient breathing circuit.

Abstract: A method and apparatus for providing circulatory and respiratory assistance in a patient. The method includes the steps of determining the onset and duration of at least one portion of the cardiac cycle of the patient and increasing the intrathoracic pressure in the patient by introducing a volume of a respiratory gas into the lungs of the patient during the ventricular systolic portion of the cardiac cycle. The method includes reducing the intrathoracic pressure in the patient by extracting, under either subambient or substantially ambient respiratory gas pressure, a portion of the volume of the respiratory gas from the lungs of the patient, beginning during the diastolic portion of the same cardiac cycle.

Abstract: Improved cardiocirculatory assistance is provided to a patient by detecting the onset of ventricular ejection in the cardiac cycle of the patient and selectively increasing intrathoracic pressure of the patient in relative phase with respect to the onset of ventricular ejection. Cardiocirculatory output may be monitored and the relative phase of the increase in intrathoracic pressure with respect to the onset of ventricular ejection adjusted to maximize cardiac output. The intrathoracic pressure is increased once every N cardiac cycles where N is a positive integer. The patient interface may include apparatus for supplying high frequency respiration pulses in synchronism with the cardiac cycle. Alternately, or in addition, the pulses may be used to inflate a bladder in contact with the thorax.
