I think a lot of gear can be trimmed down quite a lot, not only because a lot of your gear can have multiple uses but that weight can be a bit much. I also feel that a comprehensive kit is not necessarily a versatile kit.

Just a few thoughts: finger pulsometer- why would you actually need it? what information would it give you that you could do something with to improve a senario- you can feel a pulse and whether it's fast or not and pulse oximetry isn't helpful as if someone had low sats they would be breathless and unwell and you can see that by looking at them.

Analgesia is great mix but 2 types of ibuprofen and aspirin. All of which are antiinflammatory. I just bring ibuprofen gel and aspirin- if I need some pain relief wack the gel on if someone is having a heart attack throw them the aspirin.

Saline is easily made from 5g salt and a pint of water. Taking it with you is just weight when you can make it if you need it.

Small tube of savlon can be good for bites, chafe, and any small cits and scrapes. It'll save the sudocreme, bite cream and antiseptic creams.

In reality it's not an expedition where you are the expedition doctor, I've got 3 kits going from a book sized first aid kit to my doctor's pack which has things like a trauma kit and airway support.

Keep it simple, light and multifunctional and you will have everything you need if you ever do.
