  • Patent number: 10758691
    Abstract: An additive gas delivery apparatus, system and method for delivery of additive gas, such as nitric oxide [NO], to a patient use a control computer configured to determine if a monitored parameter indicates that a patient is connected to the additive gas delivery apparatus, determine if the additive gas delivery apparatus is in a passive state in which it does not deliver additive gas, and activate an alarm if the additive gas delivery apparatus is in said passive state when the monitored parameter indicates that a patient is connected to the additive gas deliver apparatus. The alarm serves to notify the user of undesired non-delivery of additive gas, and so serves to improve safety in additive gas delivery systems.

  • Patent number: 10737050
    Abstract: A ventilator delivers breathing gas to a patient via a patient circuit connecting the ventilator and the patient. The ventilator is configured to, upon activation of an oxygen boost function of the ventilator, increase the oxygen concentration of the breathing gas so as to deliver oxygen-enriched breathing gas to the patient. The ventilator includes a control unit configured to determine the volume of a part of the patient circuit conveying breathing gas from the ventilator to the patient, determine a delay in delivery of the oxygen-enriched breathing gas to the patient based on the volume, and cause indication of the delay to an operator of the ventilator.

  • Patent number: 10617841
    Abstract: A vaporizer arrangement for a breathing apparatus serves the double purpose of vaporizer and pressurized supply of vapor-containing gas for direct delivery to a patient. The vaporizer arrangement has at least a first gas inlet channel for conveying a flow of a carrier gas into a vaporization chamber, a vaporizer for vaporizing a liquid into the carrier gas in the vaporization chamber, and a gas outlet channel for conveying a flow of vapor-containing carrier gas out of the vaporization chamber and toward the patient. The vaporizer arrangement further has a gas flow regulator that maintains the carrier gas within the vaporization chamber at an overpressure, and that controls the flow of vapor-containing carrier gas out of the vaporization chamber in a variable manner.

  • Patent number: 10596336
    Abstract: A ventilation system provides patient-triggered support ventilation to a spontaneously breathing patient during ongoing high frequency ventilation (HFV), and has a pneumatic unit operated by a control computer for delivery of breathing gas in response to an effort to breathe by the patient, and an oscillator for superimposing high frequency oscillation onto the breathing gas. The system further includes a bioelectric sensor that measures a bioelectric signal indicative of the patient's efforts to breathe, and the control computer controls the delivery of breathing gas in response to the patient's effort to breathe, based on this bioelectric signal. The ventilation system is hence designed for neurally triggered support ventilation during ongoing HFV, which makes the trigger mechanism of the ventilation system more precise and robust compared to known trigger mechanisms of HFV ventilation systems.

  • Patent number: 10595729
    Abstract: In a method and breathing apparatus for prediction of fluid responsiveness of a subject connected to a breathing apparatus, at least one parameter is monitored that is indicative of a degree of carbon dioxide elimination of the subject, and a positive end expiratory pressure PEEP regulator of the breathing apparatus is operated to apply a PEEP maneuver in which a PEEP applied to the subject is changed from a first PEEP level to a second PEEP level. A processor predicts the fluid responsiveness of the subject based on a change in the monitored parameter, following the change in PEEP.

  • Publication number: 20190142284
    Abstract: The present disclosure relates to a method for determination of cardiac output or EPBF of a mechanically ventilated subject (3). The method comprises the steps of introducing (S2) a change in the effective ventilation of the subject (3), measuring (S1) expiratory flow and CO2 during a sequence of analysed breaths during which the effective ventilation of the subject (3) varies, and determining (S3) the cardiac output or EPBF of the subject (3) using the flow and CO2 measurements. The method further comprises the steps of measuring (S1) also a relative variation in cardiac output or EPBF during the sequence of analysed breaths, and using the relative variation in the determination (S3) of cardiac output or EPBF.

  • Patent number: 10085673
    Abstract: In a method for continuous and non-invasive determination of the effective lung volume, the cardiac output, and/or the carbon dioxide content of venous blood of a subject during a sequence of respiratory cycles, the inspiratory and expiratory flow, and the carbon dioxide content of at least the expiration gas are measured. In each respiratory cycle, a first parameter related to the subject's fraction of alveolar carbon dioxide, a second parameter related to the carbon dioxide content of the subject's arterial blood, and a third parameter related to the subject's carbon dioxide elimination are determined based on the measured inspiratory flow, expiratory flow and carbon dioxide content. The effective lung volume, the cardiac output, and/or the carbon dioxide content of venous blood of the subject is determined based on the correlation of the first, second and third parameters.
