Session 1: Concentrator 101

1. Room air contains what percentage of Oxygen?

50%

25%

21%

100%

Room air contains approximately 21% of oxygen. This is the correct answer because oxygen makes up a significant portion of the Earth's atmosphere, and in normal conditions, the oxygen concentration in the air is around 21%. This level of oxygen is essential for sustaining life and allows for proper respiration in humans and other living organisms.

2. Concentrators have evolved in the last 30 years to become.....

Smaller, quieter and more reliable

Quieter, require fewer filters, there are more manufacturers

More reliable, smaller, require higher electrical consumption

None of the above

Concentrators have evolved in the last 30 years to become smaller, quieter, and more reliable. This means that over time, advancements in technology and design have allowed concentrators to be produced in smaller sizes, reducing their overall footprint. Additionally, improvements in noise reduction have made them quieter, creating a more comfortable environment for users. Lastly, advancements in reliability have made concentrators more dependable, reducing the likelihood of malfunctions or breakdowns.

3. Oxygen Concentrators are all 5 LPM?

True

False

Oxygen concentrators are not all 5 LPM (liters per minute). They come in different flow rates to meet the needs of different individuals. While 5 LPM is a common flow rate, there are concentrators available with higher or lower flow rates depending on the requirements of the patient. Therefore, the statement that all oxygen concentrators are 5 LPM is false.

4. What do the letters PSA stand for?

Poor Saturation Accuracy

Pressure Swing Adsorption

Positive Saturation Adsorption

Pressure Swing Accuracy

PSA stands for Pressure Swing Adsorption. This is a process used in gas separation and purification, where a gas mixture is passed through a solid adsorbent material. The adsorbent selectively adsorbs certain components of the gas mixture, allowing the desired gas to be separated and purified. The pressure is then reduced, causing the adsorbed components to be released from the adsorbent. This method is commonly used in industries such as gas refining, hydrogen production, and air separation.

6. All concentrator systems require which of the following components?

Four sieve beds, A/C & D/C, compressor, valve system

Compressor, 1 sieve bed, electrical, valve system

Three sieve beds, A/C electrical power, compressor, motor

Two sieve beds, electrical power, compressor, valve system

Concentrator systems are devices used to separate and purify gases, such as oxygen. In order to function properly, they require certain components. The correct answer states that concentrator systems require two sieve beds, electrical power, a compressor, and a valve system. Sieve beds are used to separate the desired gas from other gases, electrical power is needed to provide energy for the system, a compressor is necessary to increase the pressure of the gas, and a valve system is required to control the flow of gases within the system. This combination of components ensures the proper functioning of the concentrator system.
