Here you can find answers to the most frequently asked questions about CorPatch®, CorPatch® Trainer and the free apps.

What to do, if you witness a cardiac arrest?

If you witness an unconscious person who is not breathing, provide first aid immediately.

  1. Check whether the person is conscious and breathes normally.
  2. If not, call for help from the Emergency Medical Services (1-1-2).
  3. Begin CPR.
    • The chest should preferably be free and bare. Give 30 chest compressions with a depth of 5-6 centimeters at a rate of 100-120 pressures per minute followed by two rescue breaths. Repeat.
    • Here, CorPatch® connected to the free CorPatch® app, can help you improve the quality of your CPR and guide you in relation to depth, recoil, frequency and flow fraction.
  4. If you are alone, call out loud for help but continue to perform CPR.
  5. If you have others to assist you, tell them to retrieve an AED.
  6. Continue with CPR until the person wakes up, or until a Community First Responder or Emergency Medical Services arrives and take over.

IMPORTANT! Always continue CPR until the person wakes up or professional help arrives and takes over. In some cases, an electrical shock from an AED can restart the heart, but it is not all hearts that have a ‘shockable’ rythm, and therefore continuous High Quality CPR is crucial. Never leave an unconscious person alone to pick up an AED!

CorPatch® FAQ

Why is good and regular CPR training not enough to perform effective CPR?

Studies show that many CPR skills acquired at a first aid course are forgotten after just three months, and most after 6 months. This life-saving knowledge will slowly vanish if not properyly maintained or regularly trained, which is possible with CorPatch®.

It can be a very stressful experience to witness a cardiac arrest, and this can cause the bystander to panic or not to do anything at all out of fear of making the problem worse. Regular training cannot predict the actual reactions from the bystander, but you are better prepared for the situation. Hopefully, the free  CorPatch® app will increase your confidence to act, and when connected to a CorPatch®, it will guide and help you to perfom high quality CPR.

How easy is CorPatch® to use in a stressful situation?

The free CorPatch® app is very user-friendly and will guide you to recognize a cardiac arrest. The app will tell you to chevk for vital life-signs and call EMS (1-1-2) if a cardiac arrest is at hand. If connected to a CorPatch®, it can also guide you to perfom high quality CPR.

Furthermore, CorPatch® has a self-train function to prepare you to use CorPatch® and the associated free app in a real-life situation. For more detailed information, feel fre to check out our User Guides.

How much time do I use on CorPatch® before I begin to perform CPR?

We recommend that you place the free CorPatch® app on the home screen on your smartphone, so it is easy to find. This way you are also informed about all relevant news on guidelines and other news related to cardiac arrest.

In the event of a cardiac arrest, you simply need to open the free CorPatch® app and tap ’emergency’. Now you are ready to start daignosing cardiac arrest, and if a cardiac arrest is at thand, you simply have to remove the CorPatch® from its enclosure and place it on the chest of the victim. Then you are ready to start chest compressions.

If well prepared, this can happen within few seconds, and this way you can maximize the blood flow to the brain and improve survival chances considerably.

How can I be sure that CorPatch® makes a difference when I perform CPR?

CorPatch® and the free CorPatch® app are developed to empower you to act, if you witness a cardiac arrest. The CorPatch® and app will guide you to perfom quality CPR, but it cannot ‘do it for you’ e.g. give compressions or rescue breaths. It is a supplement that makes it easier to perform quality CPR as you will receive live guidance on your performance, if you have a CorPatch® connected to the free app.

If you do not feel confident to do rescue breaths, do not worry. Chest compressions alone will also improve survival chances if you start fast enough, since there is oxygen in the blood at that time, which can saturate the brain for some minutes.

We always recommend you sign up for a first aid course to gain the relevant CPR knowledge, which you can combine with the skills acquired through CorPatch®.

Some AED's can measure compression depth when you perform CPR. Why should I use CorPatch® instead?

The CorPatch® is designed to assist the bystander in the first crucial minutes after a cardiac arrest before the arrival of an AED or ambulance. It is recommended by the European Resuscitation Council to immediately start CPR – mainly chest compressions, but also rescue breaths if you feel confident to do so. Send somenone else to pick up an AED, if there are more than one bystander at the scene, but do not go yourself! Chest compressions are much more importable in imporoving survival chances.

Many AED models can only provide a metronome-like rhythm to guide the rescuer, while mainly new AEDs are able to measure the compression depth and frequency. The main function of an AED is to shock the heart and hopefully ensure ordinary hearth-rhythm – not to guide compressions.

Can I damage the victim or myself when I perform CPR with CorPatch®?

The shape, size and hardness of the CorPatch® is designed to reduce the possibility of hurting the victim and the bystander. The feedback system can help to ensure that the bystander does not put unnecessary pressure on tyhe victim’s chest.

CorPatch® also has a built-in positioning ‘patch’ that shows the bystander exactly where on the victim’s chest to place the CorPatch® before starting CPR. This ensures that you compress in the right position and do not injure the victim.

Do not use CorPatch® on children. It is only intended for use on adolescents and adults.

Are there any evidence supporting the accuracy and measurements of CorPatch® and CorPatch® Trainer?

CorPatch® has been developed with the combined efforts of researchers and behavioural scientists from several countries, and it follows the strict guidelines for resuscitation as released by the European Resuscitation Council. The Guidelines are published every 5 years, and they are basesed on abundant scientific studies.

CorPatch® measures the relative movement with ± 1 millimeter accuracy, which is very precise. You can confidently trust the guidance that CorPatch® provides.

If I get instructions from the CorPatch®, AED and EMS at the same time, what instructions should I follow?

If you witness a cardiac arrest, the free CorPatch® app will ask you to call EMS (1-1-2) after you check for vital life signs. Always follow the instructions from the EMS but tell them that you use a CorPatch® that will give you immediate feedback on your CPR performance and guide you to perfomr high-quality CPR.

If you are more than one bystander at the scene, send someone to pick up an AED while you continue CPR. After you apply the AED, follow its instructions when it anlalyses heart rhythms, and stay clear if it provides a shock, but otherwise continue to follow the cuidance in the free CorPatch® app.

Continue CPR and follow CorPatch® feedback until professional assistance arrives and takes over, unless the patient has been resuscitated by the shok of an AED or your CPR.

Why should I use a CorPatch® if I can perform CPR just as effectively without?

If you are completely certain about your CPR performance over time, then you are the ideal first aid rescuer. But how do you know how well you perform CPR without any measurement? Are you not doing compressions blindfolded?

Studies show that many people are not confident about their CPR skills, and uncertainty is one the most common reasons for opting out of performing first aid.

The CorPatch® free app can hopefully increase the confidence and ensure that everyone is well prepared in case they witness a cardiac arrest, and if connected to a  CorPatch®, you can be guided to perform quaility CPR. After all, spending a little time to ensure quality CPR performance is better than not performing CPR at all.


Do I need a first aid course before I purchase a CorPatch®?

We recommend that you participate in a first aid course to be prepared and know what to do in case of cardiac arrest. A learning experience with other course participants is extremely helpful in giving you the required confidence to act.

You can see a list of our partners that prode CPR course with the CorPatch® technology on our website. It will give you a much better leraning experience and prepare you to use the CorPatch® technology in a real-life situation.

 CorPatch® Trainer FAQ

Why should I use CorPatch® Trainer in my first aid course?

The CorPatch® Trainer and the free CorPatch® Trainer app give your course participants live feedback based on individual performance data, and this can improve the experience in the course.

As an instructor you can see exactly where each participant needs to improve their CPR performance in relation to flow fraction, depth, recoil and frequency. With CorPatch® Trainer, you can increase the confidence of the participants as they receive specific feedback, rather than just a general comment.

Together CorPatch® Trainer and CorPatch® are a ‘Train-As-You-Fight’ concept, using similar guidance, so the course participants can train and get comfortable with CorPatch® Trainer and then use the CorPatch® in real life, if they witness a cardiac arrest.

Instructors who use CorPatch® Trainer in their first aid courses can sell the CorPatch® to course participants as part of the first aid course, offering them an extra parameter that sets them out from the crowd.

What kind of equipment do I need for using the CorPatch® Trainer?

CorPatch® Trainer requires only little equipment to get started. You can use your existing manikins to place each CorPatch® Trainer on, a tablet, a QI-charger and of course the CorPatch® Trainer.

Each CorPatch® Trainer must be connected via Bluetooth® to a tablet (one tablet for each CorPatch® Trainer) for the training situation.

Each tablet sends performance data from each course participant to ‘CorPatch® Services’ – a data cloud – where the instructor can retrieve and examine it on a separate tablet.

It is possible to purchase the CorPatch® Trainer individually if you already have a suitable Android tablet and QI-charger, or with tablets and QI-charger included. Please visit our webshop to learn about the packaged solutions or inquire for special solutions.

If you have your own tablets, or you prefer to purchase the tablets elsewhere, please read our information about technical specifications to effectively use the CorPatch® Trainer.

Please note! Some manikins have silicone skin, which CorPatch® does not glue on. You are welcome to check with us before purchasing CorPatch® Trainer.

How do I set up CorPatch® Trainer for a first aid course?

Charge the CorPatch® Trainers in advance of the course.

Each CorPatch® Trainer connects via Bluetooth® to the free app on the tablet, where all data from the CorPatch® Trainer is shown. In the free CorPatch ® Trainer app you can adjust the details of a course e.g. number of course participants or the parameters of CPR training, such as the depth and frequency your course participants should aim for in their performance.

For a more detailed guide on using the CorPatch® Trainer, please read the user guide.

Why should I invest in CorPatch® Trainer, if I already have manikins with feedback?

With CorPatch® Trainer and CorPatch® as part of your first aid course, you have the possibility to offer something more than the ordinary in your courses. You can improve your courses with a new Train-As-You-Fight technology that is not available anywhere else.

CorPatch® Trainer and the free CorPatch® Trainer app give accurate performance data and live-feedback and guidance to your course participants and gather a whole array of data that you can use when you develop your course offering.

With the free CorPatch® Trainer app, you can see each participants CPR performance in relation to flow fraction, depth, recoil and frequency. Your instructions to each participant will be based on live-feedback and reliable data, and you can compare CPR training without CorPatch® and without CorPatch®, giving the participant a truly unique experience, how CPR guidance works.

The CorPatch® Trainer is an ‘add-on’ to your existing manikins. This means that in the event of a damaged or non-functioning manikin, you will not have to replace or repair the CorPatch® Trainer – only apply it to another manikin of yours. Manikins with electronic components can be expensive and time consuming to repair, even if the damage is not directly to the electronic components.

Finally, when working with CorPatch® you are able to expand your offering to customers and provide something that many company clients or private customers will want to acquire before, in the course or after the course. We support you all the way with any material needed to convince customers why CorPatch® makes sense for them. Feel free to contact us at info@corpatch.com

Does the free CorPatch® Trainer app only work on a tablet?

Each CorPatch® Trainer must be connected via Bluetooth® to its own tablet, and the app has been optimized for this usage. This also means that it is very easy to use for the instructor in the course, meaning you spend a minimum of time setting it up.

In the free CorPatch® Trainer app, you can register participants’ nicknames and email addresses. If they are registered, their performance over more courses, or even in a real-life case of cardiac arrest can be measured and compared. This way course providers can follow the effect of their courses and collect data for improvements.

It is not possible to run the free CorPatch® Trainer app on a smartphone or desktop as replacement.

What is the educational gain for a course participant physically unable to perform higher quality CPR?

Some course participants e.g. elderly or disabled persons might be physically unable to perform high-quality CPR. In that case, use the data from the CorPatch® Trainer to discuss other important steps to save a life such as contacting the Emergency Medical Services (1-1-2), gathering an AED or deliver rescue breaths in between compressions if the course participant feels capable of this.

In the event of witnessing cardiac arrest with other bystanders, the course participants can use the knowledge gained at the course to guide others to act. If the course participant is the only witness of cardiac arrest, remind them that performing CPR (regardless of quality) can still increase the chances of survival.
