  • Patent number: 10780239
    Abstract: A system for controlling patient sedation and spontaneous breathing intensity includes a ventilator system that delivers ventilation to the patient. The system further includes a spontaneous breathing control module configured to determine a first spontaneous breathing intensity at a first sedative status of the patient, and a second spontaneous breathing intensity at a second sedative status of the patient. A sedation/breathing relationship is then defined between spontaneous breathing intensity and sedative status for the patient based on the first and second sedative statuses and the first and second spontaneous breathing intensities. The spontaneous breathing control module then receives a desired spontaneous breathing intensity for the patient and determines a desired sedative status that achieves that desired spontaneous breathing intensity based on the sedation/breathing relationship.

  • Publication number: 20180344958
    Abstract: A method and system for assisting clinicians in determining when and how to perform a lung recruitment procedure. The method includes a user configurable interface that an operator or institution can set up to correspond to best practices. Based upon the information entered into the configurable user interface, a method and algorithm automatically determines when a lung recruitment procedure should be instituted. The system can either manually or automatically enable the beginning of the lung recruitment procedure depending upon the clinician and facility preferences. The algorithm includes a plurality of process steps that are carried out in a clinically-relevant order to eliminate patient condition options and to provide the appropriate recommended actions prior to initiating the lung recruitment procedure.

  • Patent number: 8479731
    Abstract: A method and apparatus for determining the presence or absence of a pulmonary embolism (PE) in a patient. The breathing gas CO2 partial pressure (PCO2) during the expiration of breathing gases by the patient, the end tidal (EtCO2), CO2 partial pressure, and the CO2 partial pressure (PaCO2) of the blood are measured. The volume (V) of breathing gases expired during the expiration of breathing gases by the patient is also measured and a relationship between changes in breathing gas CO2 partial pressure (PCO2) and changes in breathing gas volume (V) in an alveolar expiration phase of patient expiration is determined. The difference between the blood CO2 partial pressure (PaCO2) and the end expiration CO2 partial pressure is divided by the relationship between PCO2 and V produce a quantity which is compared to a threshold value. If the quantity is below the threshold value, the absence of a pulmonary embolism is indicated.

  • Patent number: 8424524
    Abstract: A method and apparatus for providing an average signal characteristic profile derived from signals obtained from different cycles of a cyclically recurring physiological phenomenon. A signal produced from first and second cycles of the physiological phenomenon is sampled at a series of data points to obtain second physiological property values at the data points. The change in the second physiological property values for the first cycle signal between a pair of successive data points and the change in the second physiological property values for the second cycle signal between the same pair of successive data points are determined and averaged. The average change amount is applied to a value of the average signal characteristic profile at one of the pair of successive data points to produce a new second physiological property value for the average signal characteristic profile at the other of the data points of the pair.

  • Patent number: 7992555
    Abstract: A ventilation system for intensified breathing that includes both a manual ventilation system and automatic ventilation system. The gas mixture from a gas supply system is supplied to a switching valve that is operable between a manual position and an automatic position. When the switching valve is in the manual position, the inhalation gas from the supply system is guided to a manual ventilation bag. When the ventilation bag is squeezed during manual inhalation, the gas flow from the manual bag is directed to the inhalation limb of the patient circuit. When the manual ventilation bag is released, the pressure within the ventilation bag falls below the exhalation pressure, thereby indicating the beginning of the exhalation phase and the re-inflation of the manual ventilation.
