The invention relates to a ventilation monitoring system comprising a ventilation data capturing device connected between a patient and a ventilator device dedicated to the patient, for collecting ventilation data between the patient and ventilator device; an on-site device; a remote device for communicating with the ventilation data capturing device and the on-site device; at least one processor; and at least one memory device coupled to the at least processor configured to: collect ventilation data from the ventilation data capturing device; transmit the collected ventilation data to the remote device/server for analysis; and generate output data comprising the instructions/commands for actioning on the ventilator device, to provide suitable ventilation support to the patient, or generate output data comprising the status of the ventilator device associated with the ventilation data capturing device.

The invention relates to a ventilator (1) at least comprising: a gas supply device (2) and a gas discharge device (3), for supplying a first fluid flow (4) to a respiratory tract (5) of a patient and for discharging a second fluid flow (6) from the respiratory tract (5) back into the ventilator (1) or to a surrounding area (7); a pressure sensor (8) for sensing a pressure (9) in the respiratory tract (5); and a control device (10) for operating the ventilator (1); wherein the fluid flow (4, 6) can be set to a constant value at least during an inspiration process (11) and an expiration process (12). The invention further relates to a method for determining at least a tissue-related resistance of a patient by means of a ventilator (1).

Proposed concepts thus aim to provide schemes, solutions, concepts, designs, methods and systems pertaining to improving the allocation of COPD patients to a remote patient monitoring, RPM, program. Patients are periodically assessed so that they are dynamically placed in an optimal RPM program for their current state of health. Patients are therefore monitored and assistance can be given where necessary. By placing patients in the optimum RPM program, burdens on both patient and the service provider are reduced.

A method for characterizing sleep disordered breathing may include identification of at least one of a plurality of predefined airway structural sources associated with a sleep disordered breathing event based on airflow data. In one example, an identification of at least one of a plurality of predefined airway structural sources associated with a sleep disordered breathing event is made based on data indicative of a ratio of a difference between a peak inspiratory airflow rate and a mid-inspiratory airflow rate to the peak inspiratory airflow rate captured during occurrence of the sleep disordered breathing event.
