The devices for oxygen therapy
To carry out the oxygen therapy, there are mainly three kinds of
the oxygen devices to choose.
The first one is Compressed oxygen cylinder, this type of
oxygen is stored under pressure in steel or aluminum canisters and must be
purchased from a supplier. Many hospitals use the steel type. The cylinder
shall be connected to the oxygen delivery devices, then can play the role. The
advantages of the device are low price, easy to get and no waste or loss. But
it is heavy, with small oxygen storage and need to be repeatedly filling. In
the market, there are models like 2L, 3L, 4L, 6L, 8L, 10L, 15L, 40L ect. The
storage is calculated under 130 ATM(standard atmospheric pressure), 2L=260L
oxygen ,3L= 390L oxygen,… 40L = 5200 L oxygen.
The second one is Liquid oxygen. Liquid oxygen is
stored at a very cold temperature( around -166.7℃);
it becomes a gas when released from the container. Like compressed gas, liquid
oxygen must be purchased and stored in canisters and may include an
oxygen-conserving device. 0.028m³liquid
oxygen = 24.35 m³gaseous oxygen. The type device can store the liquid oxygen from 18.16~45.4kg,
in normal working pressure,0.45kg liquid oxygen equals to 344L gaseous oxygen,
that’s to say, one liquid oxygen can store 13760~34400L gaseous oxygen.
Usually, the general portable liquid oxygen cylinder is about 4kg. The
advantages of the device are low pressure, high oxygen storage,light and easy
to refill, it is suitable for long term rehabilitation. But its cost is
expensive, easy to be wasted and leakage. When the patient needs to use more
than 10 compress oxygen cylinder, suggest to apply this type.
The third one is oxygen concentrators or enrichers. This device
uses the electricity and eliminates the N2,CO2 in the air, and then provide
higher purity oxygen to the users. There are two kinds at present, one is
molecular sieve concentrator which is based on the PSA( Pressure Swing
Adsorption), Like the lovego portable oxygen concentrator, Simplygo POC; the
other is membrane concentrator, which is based on the different through rate of
various gas. The advantages of the devices are no need to store oxygen and with low cost, more convenient
for home LTOT. Of course, the price to buy is a little expensive, with nosie
and not easy to move for the stationary type. If you want to go outside, there
are many portable types for choosing too.
While choosing the device, we shall take the factors like economic
condition/ safty/ product
reliability ect into consideration and make a rational choice. Now the
oxygen concentrator is more and more hot and acceptable by users.
