Measuring Ability of Volunteers to Power a Bicycle-powered Oxygen Concentrator

2016-09-21 20:23:22 | BioPortfolio

Summary

We would like to test how well human volunteers power a modified oxygen concentrator. We modified the oxygen concentrator to be powered by a bicycle instead of wall power so that it can be used in low resource countries where the power supply is unreliable.

Description

We would like to test how many people can power the oxygen concentrator by pedaling the bike for at least 30 minutes. If the volunteers can bike for at least 30 minutes, we assume they are pedaling at or below their lactate threshold. We have literature values which suggest bigger people should be able to output more work, and we wish to use a sample of the population to verify that most of the people can power our system. We have a good estimate of the power required by our system, and we want to verify the average person can actually do what we calculated is necessary.

Medical and Biotech [MESH] Definitions

The use of a bicycle for transportation or recreation. It does not include the use of a bicycle in studying the body's response to physical exertion (BICYCLE ERGOMETRY TEST see EXERCISE TEST).

Expenditure of energy during physical activities. Intensity of exertion may be measured by rate of OXYGEN CONSUMPTION; HEAT produced, or HEART RATE. Perceived exertion, a psychological measure of exertion, is included.

Any method of measuring the amount of work done by an organism, usually during PHYSICAL EXERTION. Ergometry also includes measures of power. Some instruments used in these determinations include the hand crank and the bicycle ergometer.

Physical activity which is usually regular and done with the intention of improving or maintaining PHYSICAL FITNESS or HEALTH. Contrast with PHYSICAL EXERTION which is concerned largely with the physiologic and metabolic response to energy expenditure.

The state of weariness following a period of exertion, mental or physical, characterized by a decreased capacity for work and reduced efficiency to respond to stimuli.
