I‘m thinking for example how to do the Heimlich maneuver on others or on yourself, what to do during an earthquake and similar things.
I‘m having lots of fun learning new things with Anki and thought a deck like this would be a good addition. Of course hoping I won‘t ever need to apply any of it.
Take a modern first aid class. Some of the things taught in recent decades (mouth-to-mouth CPR, tourniquets, heimlich maneuver) are no longer advised for. And as certain tools became readily available for trending problems (NARCAN for opioid overdoses), new trainings are prioritized that someone going through first aid classes a decade-plus ago wouldn’t have learned about.
“Normal” first aid today will teach about scene assessment, AEDs, chest compressions only CPR, and NARCAN. A wilderness first aid class would teach things with the assumption trained medical help is not 30 min or less away (broader scope of scene assessment, tourniquets and splinting bones, hypothermia, animal bites, evacuation, +).
I took a CPR class about a month ago in the US, and artificial ventilation is still strongly recommended. Otherwise, oxygen levels slowly drop off, making chest compressions less effective over time.
Chest compressions only are better than doing nothing, and most CPR trained people probably don’t have a mouth cover for sanitary ventilation unless a medical kit is nearby (most places in public have one).
Doing ventilation correctly takes some practice, which is why inexperienced people are told to do chest compressions only during emergencies. But if you take a dedicated CPR course, they still teach and recommend ventilation.
