How Well Do You Know Oxygen Bags, Oxygen Cylinders And Oxygen Generators

How Well Do You Know Oxygen Bags, Oxygen Cylinders And Oxygen Generators

1: Oxygen bag: (also known as oxygen bag)

Capacity: Most of the current market is 42L capacity
Use time: about 20 minutes (2L/min flow premise)
Volume: after being filled, it is like an air-filled pillow
Weight: Negligible Reuse: Oxygenation can be repeated, and the oxygenation method is simple, both oxygen generators and oxygen bottles can be used to oxygenate it
Storage: It is not suitable for long-term storage. It can be stored for 24 hours after oxygenation. It is not recommended for longer periods of time.
Oxygen supply: 0.5L/min~2L/min is recommended
Oxygen use cost: the cost of oxygen inhalation for one hour is about 0.5 yuan (PS: calculated according to the oxygen charge of the oxygen generator)
 
Summarize:
Advantages: light weight, medium volume, re-oxygenation
Disadvantages: The use time is short and cannot be stored for a long time due to the large volume, which is somewhat conspicuous
For people:
Occasional short-term use (about 30 minutes), such as pregnant women or COPD travel.
 

2: Oxygen cylinder: (aka oxygen tank)

Oxygen cylinders are currently divided into two types: portable oxygen cylinders and medical oxygen cylinders
 
(1) Portable oxygen cylinders: (I call them hypoxia psychological comfort bottles)
Capacity: 800～1000ml
Number of uses: about 20 times (it has a lot to do with the time of a single breath)
Volume weight: all are very small, easy to carry
Disposable: not reusable, discarded after use
Preservation: It can be stored for a long time without opening
 
Summarize:
Advantages: light weight, small size and easy to carry
Disadvantages: The use time is short and oxygenation cannot be repeated Applicable people: People with psychological hypoxia, not suitable for patients with real hypoxia, because the capacity is too small. (PS: For those who really need oxygen supplementation, they need to inhale about 2L of oxygen per minute, and it will last for about 1 hour or even longer.)
 
(2) Medical oxygen cylinders: (also known as high-pressure oxygen cylinders)
Capacity: The common capacity is: high pressure 2L/4L/7L/10L/15L, the largest 40L is the one in the hospital
Use time: You can look at the volume weight in a table: the larger the capacity, the more bulky it is
Reusable: oxygenation can be repeated, but you need to go to a professional tank oxygen station to tank oxygen
Preservation: It can be stored for a long time without opening
Oxygen supply: 0.1L/min to 20L/min or more, almost unlimited
Oxygen fee: The cost of oxygen inhalation for one hour is about 2 yuan (PS: the price of oxygen inhalation varies from place to place, this is for reference only)
 
Summarize:
Advantages: Large capacity because it is a high-pressure oxygen storage, so it can be used for a long time and can be repeated oxygenation
Disadvantages: The volume and weight are relatively bulky and the pressure is high, so pay attention to the storage safety of oxygen cylinders
Applicable people: Oxygen cylinders are used as a backup emergency oxygen source that cannot be separated from oxygen for 24 hours, such as: power failure, oxygen generator failure and other emergencies.
 
 

3, oxygen generator (PSA molecular sieve oxygen generator)
Mainly divided into two types: desktop oxygen generator and portable oxygen generator
 
(1): Desktop oxygen generator
Capacity: as long as there is electricity, it can continuously produce oxygen. Use time: ensure that the operating temperature is not high, and it can be used continuously for 24 hours.
Weight: The larger the oxygen production capacity, the better the quality, the larger the volume and weight of the machine
Oxygen supply: the maximum oxygen production capacity ranges from 1L/min to 3L/min to 5L/min
Cost: The cost of oxygen inhalation for one hour is about 0.5 yuan (PS: calculated according to the electricity cost of the oxygen generator)
 
Summarize:
Advantages: Most of them can supply oxygen for 24 hours for a long time. The king of long-term oxygen supply is cost-effective. The oxygen supply is stable and the size can be adjusted. It is easy to operate.
Disadvantages: Large size (refer to the size of the suitcase) Noise requires a stable power supply of 220V400 power Suitable for the crowd: People who need long-term oxygen inhalation, such as the elderly with chronic lung diseases/cardiovascular and cerebrovascular diseases, and a small number of pregnant women/premature infants, etc. People who need stable medical oxygen supply.
 

(2): Portable oxygen generator
Capacity: as long as there is electricity, it can continuously produce oxygen
Use time: ensure that the operating temperature is not high, and the volume can be used 24 hours a day
Weight: Most of them weigh no more than 2KG for portable use, and the volume is the same as 4 bottles of soda water
Oxygen supply: the maximum oxygen production rate is 0.2/min~1.2L/min, the effect can be equivalent to 1L~6L/min oxygen
Cost: The cost of oxygen inhalation for one hour is about 0.2 yuan (PS: calculated according to the electricity cost of the oxygen generator)
 
Summarize:
Advantages: small size, can be used with matching batteries to go out and use, can supply oxygen continuously for a long time or even 24 hours, and the oxygen concentration is stable at most altitudes of 4000 meters.
Disadvantages: The effect of the pulse oxygen supply mode needs to be strengthened, the purchase price is expensive and the later maintenance cost is high. Suitable for the crowd: need to go out for long-term stable oxygen supply, such as: plateau hypoxia/COPD travel, etc.
