Portable Oxygen Concentrator - Development

Development

Portable oxygen concentrators have been around for decades; but the older versions were bulky, unreliable, and were not permitted on airplanes. Since 2000, manufactures have improved their reliability and they now produce anywhere between one and six liters per minute (LPM) of oxygen. The portable concentrators plug directly into a regular house outlet for charging at home or hotel; but they came with a power adapter that can usually be plugged into a vehicle DC adapter. They have the ability to operate from the battery power as well for either ambulatory use, or away from a power source, or on an airplane.

Famous quotes containing the word development:

    The young women, what can they not learn, what can they not achieve, with Columbia University annex thrown open to them? In this great outlook for women’s broader intellectual development I see the great sunburst of the future.
    M. E. W. Sherwood (1826–1903)

    I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.
    Benjamin Harrison (1833–1901)

    The work of adult life is not easy. As in childhood, each step presents not only new tasks of development but requires a letting go of the techniques that worked before. With each passage some magic must be given up, some cherished illusion of safety and comfortably familiar sense of self must be cast off, to allow for the greater expansion of our distinctiveness.
    Gail Sheehy (20th century)
