While Googling a first aid question I had, I ran across the UK Maritime and Coastguard Agency website. In case anyone is interested, there's an online version of The Ship Captain's Medical Guide. There are links to PDF chapters in this guide. I only skimmed chapter 1, which covers your traditional first aid, but there are also chapters on general nursing, communicable diseases, and other topics that may be of interest to people.

In some ways, being stuck far out at sea with a medical situation sounds like it could be similar to what some people may face when cut-off from medical services for some time after a major earthquake, hurricane, or that next pandemic.

Arney, thanks very much for sharing this link.

Good stuff, Arney, I just downloaded the entire thing to print and put on my Kindle.

Another big thank you to Arney - what an excellent resource!

I bought this book some years ago, and would highly recomend it both to read before any emergency occurs, and as a reference book during emergencies.

A few sections are only relevant at sea, but in general the advice is just as useful on land, in remote locations, or if some emergency prevents access to medical help.
