10894136 · 2021-01-19 · ·

A capnotracking method for continuous determination of cardiac output or EPBF of a mechanically ventilated subject includes the steps of measuring expiratory CO2 of the subject and determining a first value of cardiac output or EPBF of the subject at a first point in time; controlling the mechanical ventilation of the subject to keep a level of venous CO2 of the subject substantially constant between the first point in time and a second point in time; determining from the expiratory CO2 measurements a change in alveolar CO2 of the subject between the first and second points in time; and determining a second and updated value of cardiac output or EPBF of the subject based on the first value and the change in alveolar CO2.

PATIENT SPECIFIC AUTO-FLOWRATE CONTROL

A respiratory assistance system can provide high flow therapy to patients. The respiratory assistance system can include a patient interface that can deliver a gas flow to a patient and a gas source that can drive the gas flow towards the patient interface at an operating flow rate. The system can include a controller for controlling the operating flow rate of the gas. The controller can apply multiple test flow rate values in a range as the operating flow rate. For each of the test flow rate values, the controller can measure a patient parameter. The controller can determine a new flow rate value based on the measured patient parameters. Patient parameters can include respiration rate, work of breathing, or any other parameters related to the respiratory circuit.

Respiratory mask

A respiratory mask, a mould for a respiratory mask, as well as to a method for producing a respiratory mask are disclosed, in which manufacturability and usability of respiratory masks are improved. A respiratory mask is disclosed for administering a breathable gas to a patient, the respiratory mask comprising a first component formed from a flexible material and a second component formed from a material that is more rigid than the flexible material, wherein the first component is formed onto the second component by an overmoulding process.

Apparatus to attain and maintain target end tidal partial pressure of a gas

A processor obtains input of a logistically attainable end tidal partial pressure of gas X (PetX[i].sup.T) for one or more respective breaths [i] and input of a prospective computation of an amount of gas X required to be inspired by the subject in an inspired gas to target the PetX[i].sup.T for a respective breath [i] using inputs required to utilize a mass balance relationship, wherein one or more values required to control the amount of gas X in a volume of gas delivered to the subject is output from an expression of the mass balance relationship. The mass balance relationship is expressed in a form which takes into account (prospectively), for a respective breath [i], the amount of gas X in the capillaries surrounding the alveoli and the amount of gas X in the alveoli, optionally based on a model of the lung which accounts for those sub-volumes of gas in the lung which substantially affect the alveolar gas X concentration affecting mass transfer.
