Abstract: A respiration monitoring method and a respiration monitoring apparatus are disclosed. The method includes: according to airway pressure data which are measured by the pressure sensor in a respiratory cycle and gas flow rate data which are measured by the flow sensor in said respiratory cycle, calculating an intrapulmonary pressure of an inspiratory phase of a patient and an expiratory pressure of said patient, which pressures correspond to said respiratory cycle; and determining a driving pressure of said patient, which pressure corresponds to said respiratory cycle, according to the intrapulmonary pressure of the inspiratory phase and the expiratory pressure. In this way, a driving pressure can be obtained without manual intervention, such as inspiratory and expiratory hold, and the driving pressure can also be measured in real time; and since ventilation is not interfered with, a patient-friendly effect is also achieved.

Abstract: A medical device and a method for measuring a positive end-expiratory pressure are disclosed. The method includes acquiring an airway pressure and an air flow rate when a medical ventilation device ventilates a patient; obtaining a ventilation volume according to the air flow rate; and then obtaining, by means of calculation, a total positive end-expiratory pressure according to a preset respiratory mechanics equation, the airway pressure, the air flow rate and the ventilation volume. The disclosed method does not require any expiratory hold operation during the process of measuring a positive end-expiratory pressure, and thus a normal ventilation process is not interrupted. Accordingly, the method is suitable for use in both invasive and non-invasive ventilation.

Abstract: The invention is related to ventilation apparatuses and methods for operating a ventilator of a ventilator apparatus. In the method at least one duration ratio factor is set in a computing system of the ventilator apparatus; at least one minute volume, at least one functional dead space volume and at least one time constant are determined; a respiration frequency is computed, based on a previously defined lung model, depending on the determined parameters. The computed respiration frequency is optimized on at least one minimum of a delivered parameter, which is induced to a patient using the ventilator; an inspiratory time and an expiratory time are determined based on the computed respiration frequency and the duration ratio factor; at least one tidal volume based on the previously computed respiration frequency and the determined minute volume is computed; and a delivered respiratory parameter of the ventilator is closed loop controlled.

Abstract: A plurality of flow rate values associated with pressurized air directed to an airway of a user of a respiratory therapy system is received. A plurality of pressure values associated with the pressurized air directed to the airway of the user is received. A first time associated with a first breath of the user and a second time associated with a second breath of the user are identified. The plurality of flow rate values is filtered based at least in part on the identified first time and the identified second time. The filtering produces a subset of the plurality of flow rate values. An intentional leak characteristic curve for the respiratory therapy system is determined using at least two of the subset of the plurality of flow rate values and the corresponding pressure values for said at least two of the subset of the plurality of flow rate values.

Abstract: Systems slow breathing with positive pressure therapy. In embodiments, a current interim breathing rate target is set, and periodically magnitude of a variable pressure waveform scaled to the current interim breathing rate target is increased if breathing rate is greater than the interim rate target to lengthen breath duration. The magnitude of the pressure increase may be a function of the difference between the interim rate target and the breathing rate. The interim rate target may be reduced in response to slowing breathing rate. The waveform cycles, inhalation to exhalation, when airflow decreases to a cycle threshold. Different interim rate targets have different cycle threshold functions that allow easier cycling as the interim rate targets decrease. Similarly, the waveform triggers, exhalation to inhalation, when airflow increases to a trigger threshold. Different interim rate targets have different trigger threshold functions that allow easier triggering as the interim rate targets decrease.
