Pooling some trivia

In my role, I need to know how to perform Cardiopulmonary Resuscitation, or CPR, so I attended a session this week. The cycle is a bit funny ironic: Need to learn CPR -> hope that you never need to use CPR -> wish fulfilled -> forget CPR -> need to learn CPR.

Anyway, some learnings from the session:

• As first responders, you are expected to Send for help. The instructor told us specifically not to say, “call an ambulance” – I guess if a pack of bystanders happened to be tourists from overseas, you waste less time in case they get the number wrong. 🚑🚑🚑

• The correct thing to say is “call 000!” (Or insert locally relevant number). The other number for Australians is 112.

• Nobody has ever been successfully sued for breaking ribs while administering CPR. People have tried, though. Seems a tad ungrateful, doesn’t it?

• Currently, the estimated time it takes for an ambulance to reach a victim/patient in our state is about 40 minutes, which is absolutely terrible.

• Parents can sometimes misjudge their child’s ability to stay safe in a pool – forgetting that swimming lessons might be in warm water, whereas cold water elsewhere gives the child a shock.

• The blue-ringed octopus is found near our waters, and despite being tiny creatures, their bite can paralyse the muscles you use for breathing.


No real uni-related things in the last fortnight (and none for a while).

I have recently taken up tutoring some primary school kids, and that’s been fun. Out of nowhere, one child asked me if watermelons float or sink in water. I was completely flummoxed. I told her I would find out for her and come back with an answer next week – (“Do you have a swimming pool?” “No, I meant I’ll look on the internet for you”).

Turns out that:

• Watermelons are buoyant in water.


Hope everyone is well in blog-land.

  1. That watermelon looks so enticing, but I have this weird watermelon allergy. Can’t eat it. It’s so strange (and sad). 😀 I’m going to check out blue-ringed octopi. That’s an interesting factoid about their ability to paralyze respiratory muscles.

    Have a good rest of the week! 🙂

  2. CPR ? Work ( medical research, first real job) insisted all staff qualify in first aid. CPR works. chest pushes & own breath into patient. Small difference….
    My patient was a newborn, not breathing calf. His mother quite big, but let me get on with it. He started breathing, struggled to his feet,
    No human experience, yet. Hope it never happens..
