Neuro Exam:
1. Orientation
Does the diver know their own name and age?
Does the diver know the present location?
Does the diver know what time, day and year it is?
Note: Even though a diver appears alert, the answers to these questions may reveal confusion. Do not omit them.
2. Eyes
Have the diver count the number of fingers you display, using two or three different numbers.
Check each eye separately and then together.
Have the diver identify a distant object.
Tell the diver to hold head still, or you gently hold it still, while placing your other hand about 50cm in front of their face. Ask the diver to follow your hand. Now move your hand up and down, then side to side. The diver’s eyes should follow your hand and should not jerk to one side and return.
Check that the pupils are equal in size.
3. Face
Ask the diver to purse their lips. Look carefully to see that both sides of the face have the same expression.
Ask the diver to grit their teeth. Feel the jaw muscles to confirm that they are contracted equally.
Instruct the diver to close the eyes while you lightly touch your fingertips across the forehead and face to be sure sensation is present and the same everywhere.
4. Hearing
Hearing can be evaluated by holding your hand about 60cm from the diver’s ear and rubbing your thumb and finger together.
Check both ears moving your hand closer until the diver hears it.
Check several times and compare with your own hearing.
Note: If the surroundings are noisy, the test is difficult to evaluate. Ask bystanders to be quiet and to turn off unneeded machinery.
5. Swallowing Reflex
Instruct the diver to swallow while you watch the “Adam’s apple” to be sure it moves up and down.
6. Tongue
Instruct the diver to stick out their tongue. It should come out straight in the middle of the mouth without deviating to either side.
7. Muscle Strength
Instruct the diver to shrug shoulders while you bear down on them to observe for equal muscle strength.
Check diver’s arms by bringing the elbows up level with the shoulders, hands level with the arms and touching the chest. Instruct the diver to resist while you pull the arms away, push them back, up and down. The strength should be approximately equal in both arms in each direction.
Check leg strength by having the diver lie flat and raise and lower the legs while you resist the movement.
8. Sensory Perception
Check on both sides by touching lightly as was done on the face. Start at the top of the body and compare sides while moving downwards to cover the entire body.
Note: The diver’s eyes should be closed during this procedure. The diver should confirm the sensation in each area before you move to another area.
9. Balance and Coordination
Note: Be prepared to protect the diver from injury when performing this test.

Mark... I am in the medical business and you just gave one of the best presentations I've ever seen on the neurological symptoms and presentations of DCS... you could have been speaking to the staff of an ED (emergency department) as to the proper way to test for DCS.... as well as other neuro issues, as well. Great job, as always! My wife and I are great fans of your - keep up the amazing work. Larry
A extremely well presented video on the neurological evaluation of DCS symptoms. Your video emphasised the importance of completing a Rescue Diver course combined with First Aid/First Responder & Oxygen Provider certification.

Rescue, such an important course. Most real-world incidents aren't as calm and organized as the Open Water Course
Great video lots of useful info 👍
Really good idea for me to learn, as I'm just starting out my padi open water course. 😊😊❤❤ #askmark maybe?...
thank you for the explanation of the term "bends" excellent video
This is a lot of great info I hope I never have to use. I took a ton of notes
Great Master Class Mark!! Thanks a lot for being so good at pronunciation . very important for foreiners like me,
Excellent presentation, Mark. Thank you for refreshing my aging memory of the sign and symptoms.
I got bad itching after a dive at the Red Sea but after I went to the doctor 1 hr later he told me it’s just a regular sun burn not DCS 😂😂
It’s a little scary that so many instructors are not teaching DCS well enough

Depends what level of training you're at.
I am going to need a Rescue Diver to save me from the brain aneurysm I just had at 0:30. Maybe that diver had one, too? That would explain....whatever that is.

i don't know what's worse, the fact that he just took a shitty course with a shitty instructor or the fact that they put this clip in this video on what is supposed to be an educational scuba diving channel... imagine diving with a dude like that, ✋✊👍👍 after 10 minutes of dive.
Back in Aug I did my PADI OW Dives. A few days later I had what looked like a pimple between my nose and eye. Next morning I had a ring around my one eye. Cleared up after a few days. I was told it could have been Mask Squeeze. Don't recall experiencing anything different during the 60 ft dive that I normally don't in my college pool.

Yes, mask squeeze, your not likely to get DCS at that depth, you could get DCI, but that's a mask squeeze you're describing.

yup, that's mask squeeze, make sure you always insuflate air in your mask when you're descending.

I vote we can call it the Tropic Flounder. They are found in their natural habitat, 10m-20m, twice a year. It is a rare sighting!

He is unable to move with fins. He is disabled. That is the only one of two ways that he is able to move underwater. (The other being an underwater scooter.)

With special gloves, he is able to move underwater that way.

@@ahmedmahomed aha, cute, except disabled people that don't have leg mobility don't wear fins, and as you say, use palmed gloves... it was a rethorical question, you see...? the truth's more likely that he is just a noob that took a shitty owd course with a shitty instructor and has no idea what's actually going on.
