160 Fun Facts About First Aid

Friedrich von Esmarch, who coined 'first aid' in 1870, was a military surgeon in which country's army?

Esmarch also invented the triangular bandage that still comes in most kits, and his manual claimed it could be applied in 32 different ways.

The 1877 St John Ambulance Association taught first aid in railway centres and which other workplaces?

Its logos differ by country but always carry the eight-pointed white Maltese cross of the Order of St John.

The internationally accepted first aid symbol is a white cross on a background of which colour?

The red cross on white is legally protected under the Geneva Conventions for humanitarian and military medical use, which is why kits use the other colour.

Napoleon's surgeon Larrey created an ambulance corps known by what French name?

The name means 'flying ambulances': light horse-drawn carriages that collected the wounded during the fighting rather than after it.

What adult chest compression rate per minute have guidelines recommended since 2015?

Faster is not better: pushing too quickly stops the chest recoiling fully, so the heart never refills between compressions.

How deep should chest compressions be pushed on an adult?

That is roughly a third of the chest depth; rescuers almost always press too shallow rather than too deep.

What compression-to-ventilation ratio do guidelines recommend when giving CPR to a victim of any age?

The same ratio applies to adults, children and infants, though for babies the rescuer compresses with only two fingers.

For untrained bystanders helping an adult in cardiac arrest, which form of CPR do guidelines recommend?

The blood of a collapsed adult still holds enough oxygen for several minutes, so keeping it moving matters more than topping it up.

In 2010, resuscitation guidelines changed the opening steps for all but newborns from ABC to what?

Putting compressions first cut the delay before blood started moving; newborns kept the old order because their arrests are usually caused by airway problems.

Which Bee Gees song is famously used as a tempo guide for hands-only CPR?

Its 104 beats per minute sits neatly inside the recommended compression range, which is why the American Heart Association adopted it in training campaigns.

Which heart rhythm will an AED refuse to shock, despite what television dramas suggest?

A flatline heart has no electrical chaos to reset, so it is treated with compressions and drugs rather than electricity.

For each minute a cardiac arrest goes without defibrillation, survival chances drop by roughly what percentage during the first three minutes?

After the three-minute mark the decline steepens to about 10% per minute, which is the whole argument for public-access defibrillators.

The portable external defibrillator was invented by cardiologist Frank Pantridge in which city?

Pantridge's first units ran off car batteries and were bolted into ambulances, creating the mobile coronary care unit.

How old was the patient in Claude Beck's first successful human defibrillation in 1947?

The boy's chest was already open for an operation on his breastbone, so Beck applied the paddles directly to the heart.

The first-aid recovery position is meant for a casualty who is unconscious but still doing what?

Lying on the side lets gravity keep the tongue off the airway and lets vomit drain out of the mouth instead of down the windpipe.

For a choking adult, guidelines recommend cycles of how many back blows and the same number of abdominal thrusts?

The escalation starts even earlier: if the person can still cough, rescuers are told to encourage coughing before touching them at all.

The universal sign for choking consists of a person who cannot speak placing both hands where?

It exists precisely because a fully blocked airway makes calling for help impossible.

For a heavily pregnant choking victim, rescuers should apply thrusts to which part of the body instead of the abdomen?

The same substitution is advised for very obese people, and for babies under one, who get back blows and chest thrusts rather than abdominal pressure.

Which traditional kitchen remedy for burns does medical guidance say is not recommended?

Cool (not iced) running water within 30 minutes is what actually reduces burn depth and pain.

The Wallace "rule of nines" for estimating burn coverage is only accurate for people over what age?

Children have proportionally bigger heads and smaller legs, so paediatric burn charts use different percentages.

In 2015 he wrote that both ice and complete rest may delay healing, and newer protocols such as PEACE & LOVE drop routine icing altogether.

In the RICE mnemonic for treating a sprain, what does the E stand for?

Raising the injured limb above heart level is the one step that has survived every rewrite of the protocol.

An adrenaline auto-injector for anaphylaxis is designed to be fired into which part of the body?

Antihistamines, though widely handed out, are poorly supported by evidence and are not a substitute for the injection.

Most second waves arrive within eight hours, which is why emergency departments keep patients under observation after a reaction.

In which year did Charles Richet, who named anaphylaxis in 1902, win the Nobel Prize in Physiology or Medicine?

The pair stumbled on it while trying to immunise dogs against sea-anemone toxin aboard Prince Albert of Monaco's yacht.

It is followed in the final stage by 'terminal burrowing', an instinct to crawl into small enclosed spaces, which is why victims are found in odd places.

Which is regarded as the gold-standard cooling method for exertional heat stroke?

Fever drugs like paracetamol and aspirin do nothing for heat stroke and can worsen liver damage.

The pressure-immobilisation bandage for snakebite is recommended chiefly in which country?

It suits that country's neurotoxic elapids, whose venom spreads through the lymph; wrapping a viper bite tightly can make tissue damage worse.

Recommended tick removal is to grasp it with fine tweezers as close to the skin as possible and pull how?

Chemical tricks meant to make the tick let go by itself are ineffective, and in Australia the advice is to freeze it in place instead.

Tick bites rarely lead to infection if the tick is removed within roughly how many hours?

That window is why a daily tick check after a walk matters more than any special removal gadget.

Good Samaritan laws take their name from a parable told in which Gospel?

The ADA's '15-15 rule' for low blood sugar means eating 15 grams of carbs and rechecking after how many minutes?

Half a cup of fruit juice or regular (not diet) soda counts; the target is to lift blood glucose back above 70 mg/dL.

If someone with dangerously low blood sugar cannot swallow, which hormone may be injected?

It tells the liver to dump stored glucose into the blood, the opposite job to insulin, and now also comes as a nasal powder.

Which over-the-counter drug is an appropriate first response to a suspected heart attack?

It works by stopping platelets clumping onto the clot; women, notably, are more likely to report nausea, jaw pain or fatigue than the classic symptoms.
