Dianne Croteau and her partner Richard Brault invented theActar 911. I can only speculate that they believed a low cost alternative mannequin was needed to allow more people to have their own mannequin during training. The cost of the Actar 911 is only 1/10 the cost of a regular mannequin (a person could by 10 Actars to 1 Laerdal mannequin).
When CPR is practiced, or performed in real life, exhaled air from the rescuer into the mannequin or person is about 16%.
According to the related link, Actar Airforce Inc., Toronto, ON, Canada manufactures the Actar 911 CPR mannequin.
Some schools have Allied Health programs that teach CPR as part of the curriculum. The Mini Anne mannequin may be used in some of these programs.
It is possible to get an infectious disease from performing CPR. The risk is low, but there is a risk. That is why the ARC and AHA advise the use of a breathing barrier when performing CPR (even during class practice on the mannequin).
The related link, from USMRA, gives a brief history on Resusci Annie.
Demonstrate on a mannequin you can adequately perform the checks, breaths, and compressions during a trial run of check, call, and care.
Ask her to take a CPR class with you. Tell her you want her to be prepared to save a life. It will be better to take a class together so she can actually practice on a mannequin.
It probably is if you are looking for a CPR class for your personal benefit. If it is for a job (ski patrol, EMT, CNA) you will need a class where you actually practice on a mannequin; for example the ARC or AHA.
It saves lives every day on humans which the mannequin is supposed to simulate for practice only.
The training device is a mock Adult, Child or Infant mannequin that you use to simulate performing CPR on an actual person. These devices can be simple or quite sophisticated that have lights and read outs to confirm hand location and breaths. CPR is performed on the training devices exactly the same way you would do it on a person.
A sewing mannequin is a great resource for those who are learning to sew. A person can use the mannequin to pin pieces of material to get just the right fit.
