Evaluation of the safety and efficacy of using the Lumena mask, compared to commercially-available, commonly used Oro-nasal masks.


20 participants will be included in the study. The number of patients for each group is 5.

The trial is, a crossover trial, as all participants go through every one of the trial conditions, albeit in a different order, and thus every trial condition will have results of 20 patients in it eventually.

Prior to patient treatment, the subject will be informed about the study and potential risks, and will be givin written informed consent.

Prior to every inhalation and particle sampling, a baseline sample will be taken to filter possible carryovers from previous sampling.

Demographics including age, sex, height, weight and body mass index. Past medical history including smoking status, co-morbid conditions and medication use.

Vital signs before, during and after non-invasive ventilation: heart rate, respiratory rate, blood pressure (invasive and/or non-invasive), oxygen saturation, end-tidal capnography and temperature.

Electrocardiogram (ECG) diagrams before and after use. Arterial blood gas analysis for O2, CO2, pH and HCO3 as well as serum Lactate levels before, during (every 30 mins) and after non-invasive ventilation. A maximum of 20 ml of blood will be collected from each patient.

Room aerosol particle concertation in sizes 0.3, 0.5, 1.0 and 2.5µ. Symptoms and signs during use of non-invasive ventilation (e.g. diaphoresis, anxiety).

Estimation of patient comfort (an analog 1-5 scale as well as recording of verbal comments) - the question shall be phrased thusly: In a scale of 1-5, 1 being very uncomfortable and 5 being very comfortable, how would you rate the mask you are wearing? Estimation of staff comfort (an analog 1-5 scale as well as recording of verbal comments). - the question shall be phrased thusly: In a scale of 1-5, 1 being very uncomfortable to use and 5 being very comfortable, to use how would you rate the mask? Device related AE's will be reported by number, type, seriousness, severity and duration. All device and treatment related AEs will be captured, regardless of severity.
