An oxygen vending machine receives payment from a user. The payment is validated for appropriateness and sufficiency. If a valid payment is made, then concentrated oxygen is provided to a nipple or coupling located in an accessible place. In addition, a packaged breathing device, such as a nasal cannula, is dispensed. The user retrieves the packaged nasal device and uses it to direct the concentrated oxygen from the nipple into the user's nose or mouth. The user may select the particular breathing device which is to be dispensed. The flow of concentrated oxygen to the nipple is ceased after a predetermined period of time has passed.
