This prospective experimental study is conducted in Pauls Stradins Clinical University Hospital (PSCUH) and Sleep Disease Center in Riga, Latvia. The study includes patients with respiratory failure and hypoxemia to whom NIV is indicated.
Participants clinical parameters are monitored and samples will be sent to a clinical laboratory for analysis.
Initial ventilation parameters will be defined by the clinician who performs the experiment.
During the validation phase, the investigators will obtain clinicians' final decision on the changes of the ventilation system parameters and compare it to our module proposal. That way it would be possible to estimate if the system is ready for the next step - fully automated closed-loop ventilation system development.
