This F.A.Q. will try to shed some light on KAT Advanced Medical. We will try to keep it up to date and if you find anything wrong or you are still unsure, feel free to join our Discord [discord.gg] and use #ask-questions-here .

Q1: KAT - Advanced Medical is not working, what to do?
A1: Make sure you are using latest REWRITE version from (https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2020940806) and also that you don't have ADV ACE-CPR activated.

Q2: Why I cannot use item XYZ(Defibrillator - AED or AED-X and other KAT items)
A2: Make sure your character have proper medical level expertise. You can change it in editor on character properties and then ACE Options, where you have Is Medic: Default, None, Combat medic, Doctor. Also check out addon settings where you can change medical level required to suit your needs.

Q3: How do I use stretcher?
A3: You can find backpack containing stretcher in arsenal. After that, you can deploy it and then use it via ace interactions and context menu. You can spawn stretcher both in editor or Zeus - both will work.

Q4: What do SpO2 change values mean?
A4: There are two SpO2 change values - Small and Big. SpO2 value can decrease from multiple reasons (0 HR, Obstruction/Occlusion, XYZthoraxes and their combinations). There is also time included, so before 100 seconds, SpO2 change will be "Small" unless you combine multiple complications(2 and more) - that will become "Big". If nothing combines, after some time, it will change to "Big". Current default values are 30 for "small "value and 66 for "big" value - it can be changed in addon settings.

Q5: What is the difference between obstruction and occlusion, and how do they happen?
A5: Obstruction happens due to a loss of airway reflexes. A real world example is the tongue falling back and blocking the airway. Occlusion is a foreign body (such as emesis, blood, a crayon etc.).
In this mod, obstruction can happen only when unit goes unconscious. However occlusion can happen when unit is unconscious and chance for that is calculated every 60 seconds. They both decrease SpO2 value. In order to remove obstruction, you either need to use Guedel tube/KingLT/Acuvacc or if you don't have such tools, you can resort to hyper-extending head of the patient which will mitigate the effect of obstruction, but you need to stay close to the patient until he awakes(Awakening will result to removing the obstruction). Occlusion can be removed by using KingLT/Acuvacc or you can try head turning and according to the chance set in addon options, it will successfully remove occlusion or it won't. Chances for both obstruction and occlusion can be changed in addon settings.

Q6: What is the difference between Guedel Tube and KingLT?
A6: Guedel tube after insertion will only prevent obstructions from happening. Patient with Guedel tube still can get occlusions. KingLT will prevent both obstructions and occlusions from happening thus "permanently" securing the airway.

Q7: How do I use painkillers?
A7: Because of the ArmA limitations, painkillers that you should use are located in magazines category. From there, you can grab them and use them both via ace interaction on your head, or medical menu. You can use each package 10x.

Q8: What are the differences between pneumothorax, tension pneumothorax and hemothorax, and how do they happen and treat them?
A8: Pneumothorax can happen from extended damage to the character. Once damage threshold is crossed, chance for pneumothorax is calculated(You can adjust the chance and threshold in addon settings). Currently if unit has pneumothorax and is unconscious, his SpO2 value will drop pretty fast. When unit is conscious, it will do nothing apart from not being able to apply Personal Aid Kit to such unit - in the future, this will be revamped. Tension pneumothorax and hemothorax can happen after you suffer from pneumothorax. Currently they are just fancy new injuries, but their dangers to the patient will be expanded in the future. Hemothorax is the state in which chest cavity is filled with fluid(mostly blood and so on). Tension pneumothorax is like hemothorax, but chest cavity is filled with gas, rather than fluid. In order to treat pneumothorax, you only have to apply Chest seal to the torso. In order to treat hemothorax, you will need to apply Chest seal first and then use AAT Kit and then using that will drain fluids. To treat tension pneumothorax, you only need AAT Kit to perform needle decompression.

Q9: Pulse-oximeter, AED and AED-X - what are the differences and how do they work?
A9: Pulse oximeter is very simple device that you can put on patient arms(IRL fingers) and it can monitor HR(Hearth Rate) and SpO2. That is all what it does. AED (Automated External Defibrillator) can be used on patients torso and give him a "shock" in order to give him HR. We know that this is not realistic approach, but rather "gameplay mechanics" so stay calm and enjoy the game. Other than giving a "shock", AED cannot do anything else. AED-X is better version of AED and it does what AED does + it can monitor HR, SpO2 and BP(Blood pressure). You can connect it to the patient and it will make beeping sound(which you can turn off via ace interaction). It will be connected to that patient, so if he moves away too far from the medic, it will get disconnected. For both AED and AED-X, there are success chances which can be set in addon settings.

Q10: How blood groups work in KAT and how do I use IV stand?
A10: Each unit can choose its own blood group in addon settings if it is not forced from mission or server. If it is not forced by mission or server setting and player did not chose his blood group, blood groups will be assigned randomly. You can check the blood group by checking the dog-tag. In KAT, there are no Rh factors for blood groups, but apart from that, it will work fairly the same as in real life. There is also blood group cheat-sheet if you are unsure which blood group is compatible. If you give someone wrong blood group, you can kill him. In order to counter it, you will have to use painkillers(Tylenol). Currently blood cannot be hanged to IV stands - only the saline bags can.

Q11: Can I contribute somehow?
A11: You can, this is open-source project so everyone can make suggestions on our GitHub or even PRs. If you happen to know a foreign language and you want to make translations, go ahead, we will be very happy. You can also contribute by reporting bugs to #bug_reports and discussing relevant topics in #ask-questions-here.

Q12: Is there any documentation?
A12: Currently there is nothing official, but if you check pinned messages at our Discord [discord.gg] in #ask-questions-here, you can find plenty of documents created by the community which could serve you as "documentation".
