An Alternative Way To Deliver Oxygen To People

Study Overview
=================
Brief Summary
-----------------
The availability of oxygen is a crucial prognostic indicator for outcomes pertinent to many chronic diseases. Accordingly, interventions that might increase oxygen availability have obvious beneficial clinical application. In this regard, Respirogen Micro-Oxygen (RMO) technology holds considerable promise. Data from experimental animal models of lung injury suggest administration of RMO is a feasible method to deliver oxygen in a manner independent of pulmonary function. Our ultimate long-term goal is to provide a product that can be used to deliver oxygen to humans experiencing respiratory distress and pulmonary dysfunction In this first exploratory study, our goal is to begin to understand the physiological responses to enteral (rectal) delivery of RMO in low-oxygen environments in healthy adults at rest.

Design Details

Primary Purpose: Health Services Research
Allocation: Randomized
Intervention Model: Crossover Assignment
Interventional Model Description: Following screening, six healthy adults will report to the Human Performance Clinical Research Laboratory on two separate occasions, each separated by  7-14 days. During each visit, study participants will undergo physiological monitoring prior to and during inhalation of hypoxic (FiO2=0.15) gas mixtures. During one of these visits, following initiation of hypoxic gas breathing, colon administration of RMO will commence.
Masking: None (Open Label)
