Hypoxia in Flight Simulation in Obese Patients

Hypoxia in Flight Simulation in Obese Patients

The purpose of this pilot study is to determine whether obese adults,obese (BMI>30 kg/m2) with obesity hypoventilation or obese COPD-patients do undergo oxygen desaturation under flight simulation and if the hypoxic altitude simulation test is as effective as the hypoxic chamber test.

Inclusion Criteria:

• age ≥ 18 years
• patients with COPD (GOLD I-IV Group A-D) with obesity (BMI> 30kg/m2), obese healthy adults with BMI> 30kg /m2, patients with Obesity hypoventilation syndrome
• informed consent provided

Exclusion Criteria:

• patients less than BMI <30 kg/m2 with or without COPD, OHS
• Age < 18 years
• pregnancy, lactation
• any medical, psychological or other condition restricting the patient's ability to provide informed consent
• participation in another clinical trial
