Portable Oxygen Machines - How To Operate and Choose The Right One
Portable oxygen machines have become a necessary source of life support. But as more people need them, corporations are developing more and different machines all intended to help. The choices are many.
Anybody's lifestyle is seriously affected the minute they are told they may need supplemental oxygen. To keep the adjustment from being too drastic, it's important that the machine delivering the oxygen be as portable as possible. There are several factors that go into making the decision on the type of system that will deliver the oxygen.
How often and how much oxygen is needed is the first factor to take into account. The amount and frequency of oxygen required will influence what machine you use. Do you require oxygen only when you're sleeping? When you are eating? Or do you need it all day long?
The next criteria which may decide the type of portable oxygen machine is the amount of oxygen required. If you need more, be advised that a tank will have more oxygen than a cylinder. On the other hand tanks are at risk of losing oxygen more rapidly as a result of condensation. The final factor to think about is your lifestyle.
Check with your medical professional before you make any decision on a portable oxygen machine. Do your research ahead of time. The more you know, the more you'll be able to ask smart questions which will help you both make a decision.
You want to make a good decision because your body will adjust itself to whatever system or combination you select. While it is good that your body adjusts, it will also be a disadvantage. And that disadvantage lies in the fact that once you become accustomed to a particular system, it becomes a very difficult thing to change. It is for this reason all portable oxygen machines and possibilities should be studied carefully.
If you do not know how to work a portable oxygen machine, ask the vendor to show you. The user's manual may also be able to answer any questions you might have. We pointed out that there is a wide array of designs and machines on the market, but they all basically fall into one of 3 systems.
These consist of portable oxygen concentrators, oxygen cylinders and liquid oxygen tanks. The main units of operation are the same. For instance, every portable oxygen machine will consist of a tank valve, regulator, flow meter and flow port. Operation is easy and you will know exactly how to administer the oxygen with little or no guidance.
Oxygen must be stored carefully no matter what system you select. And handle your equipment carefully because oxygen is extremely flammable.

how do i make a simple adjustable frequency op-amp crystal radio?
i am trying to build a simple op-amp crystal radio that will fit into a 4" X 4" X 3" box.. that is simple, effective and is portable. what are some really simple portable radios? that use minimal parts? would it be possible to make a radio (crystal radio) or variable oscillator reciever that can receive all frequencies that is tunable and audible?
all freq. at once.. and have it audible so you would hear the strongest signal
Crystal radios normally receive the AM band and need an external antenna and earth. Many sites show circuits for all sorts of radio receivers, including crystal sets. Google or similar search engines will find lots of them. To receive all frequencies would require a complex radio beyond the ability of home constructors. Here is a site to start with:
