If you're a CPR instructor, you know
how difficult it is to carry heavy manikins and set up training equipment.
In this case study, we interviewed a professional CPR instructor who tested a portable
CPR training device, cprCUBE 3, during a real training session.
Here’s what worked and what didn’t.
Hello, this is Editor R.
Today, we visited Somang Rehabilitation Center
in Seongnam-si, Gyeonggi-do.
We met with Ms. Yoon Hye-ryeong, a nurse and active CPR instructor,
who conducted a training session using our new product, cprCUBE 3.
After the session, we had an interview with her.

Interview Begins!
R: Hello, Ms. Yoon Hye-ryeong! Let's start the interview.
This is IMLAB's new product,
'cprCUBE PRO 3'!
Yoon Hye-ryeong T: Oh, it's so small and cute!
R: π Thank you for your positive first impression of cprCUBE 3!
R: How do you prepare training materials and content for CPR education?
Yoon Hye-ryeong T: To conduct CPR training, I have to carry all the equipment, like mannequins.
For example, when training kindergarten teachers, kindergartens usually don't have mannequins.
Most mannequins are expensive, and those with feedback features are especially heavy.
R: What about stackable mannequins that require assembly?
Yoon Hye-ryeong T: When I go to a training session, I need to set up quickly. Assembling them takes a long time,
and it can be difficult to do alone.
Conversely, lightweight mannequins that don't require assembly are too light, which can cause them to shake excessively during training.
R: How do you typically conduct CPR training?
Yoon Hye-ryeong T: There are so many different scenarios.
The number of trainees also varies greatly.
Recently, I trained over 100 people.
For that, I set up 10 mannequins,
and trainees took turns practicing compressions.
Total Training Time
4 hours
Theory Class
2 hours
Practical Class
2 hours
Typically, a 4-hour training session consists of 2 hours of theory and 2 hours of practical training.
Many instructors have trainees complete 2 hours of online theory beforehand.
Even so, I still briefly cover theory before proceeding with the practical session.
R: What are your thoughts on conducting training with cprCUBE 3?

cprCUBE PRO 3 in action.
Yoon Hye-ryeong T: First, it's excellent for compressions.
Its small size allows me to set it up in advance, and it's light and convenient!
The price also seems good, especially compared to traditional mannequins.


When performing compressions, I received feedback via the product's LED lights.
It was great to get feedback on the three most crucial elements of CPR: depth, recoil, and rate.

CPR PLUS_Real-time feedback.
The real-time feedback displayed on my phone or tablet screen is excellent, allowing me to see if my compressions are accurate.
R: Are there any aspects of cprCUBE 3 that you find lacking?
Yoon Hye-ryeong T: Hmm, it's a bit disappointing that it doesn't support rescue breath practice.
Since lecture times are usually short,
instructors typically demonstrate how to perform rescue breaths.
It would be effective to bring one mannequin to demonstrate rescue breaths,
and then use the portable cprCUBE for multiple trainees to practice compressions.
R: The dedicated CPR PLUS app was also released recently.
What are your thoughts on using both the app's Scenario Mode and Feedback Mode?

Yoon Hye-ryeong T: In actual training, we sometimes display educational videos for practical exercises.
I usually give direct commands, but instructors with softer voices might play official training videos and use the video's commands for practice.
It would be fantastic if the app's content could be displayed on a large screen, like with a projector, so everyone could see it together during training.
Conclusion of the Interview
Today, we visited Somang Rehabilitation Center
and heard an honest review from CPR instructor Yoon Hye-ryeong
after she used our cprCUBE PRO 3.
We look forward to sharing more interview reviews from other instructors in the future!
