The air at the Dead Sea

It's my understanding that the atmosphere at the Dead Sea has a higher concentration of oxygen than the sea level norm because of the extremely low elevation (roughly a quarter mile below sea level). My question is: what does it feel like to breathe this air? Is it refreshing? Does it feel thicker than air at sea level? Are there any objective medical findings associated with long-term exposure to oxygen at this concentration? Many thanks in advance.

Oxygen for Rental for Father

My 72 year old dad just was prescribed oxygen. He has portable units and then an electric machine for home use. He is supposed to fly from Dallas to Phoenix to visit me for Thanksgiving. I saw the Southwest regulations for his portable, but should I rent him a home machine or can he check his? Are they heavy? Are they expensive to rent?

How to get an oxygen tank in the stroller.

Our baby is nearly coming home from the NICU, and the doctors have told us more than likely he will have to come home with an oxygen tank. We already bought a pram/stroller for him before we knew about this, now we aren't sure if we can fit the oxygen tank with the pram/stroller we have. I think its going to be a class D oxygen tank. Do we need a new pram or can we attach the tank somehow? [more inside]

Oxygen in food??

I was just forwarded an email from a family member that eating raw foods high in oxygen can somehow help your blood oxygen levels. This sounds like complete crap to me. I was taught that oxygen gets into our bodies via the lungs. Is there the remotest possibility that oxygen in food gets into the bloodstream? In some significant amount that the body would notice? Any biochemists out there?

Semi-humourous sci-fi short story ID

I'm trying to remember a science-fiction (?) short story that I read about 10-15 years ago. Basically, a bunch of prominent citizens of Earth (including Miss Universe) are summoned to Mars to be harangued by a sarcastic alien who tells them they're all doomed. [more inside]

How would the Horta actually work?

"Silicon based life" is a perennial sci-fi trope - I guess because silicon and carbon share similar-ish valency properties. Has anyone actually tried to flesh out what a silicon chemistry complex enough to support protein analogues would look like? Or more broadly, has anyone proposed schemata for complex, self-replicating chemistries that differ substantially from those we know?

Need to find a pulse/ox monitor

Pulse-Ox monitors (the little dealies that fit over your finger and measure oxygen saturation in the blood). Need to buy one for an asthmatic person. What are reputable brand names, places to order, etc? I'm in Canada, so shipping availability to Canada is essential (if ordered online), or local resources in Toronto.

Breathe, breathe in the air...

Not to start a fight but I am curious about this one...If the entire atmosphere is 100% and nitrogen is 89% and the inert gases are 0.9% and the rest is the O2 we breathe and more and more CO2 is being made [carbon burning made that is] from that O2 and not going back out of the system as released O2 will we see a drop in the amount of O2 we have to breathe? Does the actual % of the various gases get checked on by anyone? And would we see it first decline at higher altitudes or in the deaths of animals who need more O2 for their specific needs..........which ones are the mine canaries here?

traveling with oxygen

I'm working to transfer a person on oxygen from San Diego to Oregon. It's a long trip and this person is mostly wheelchair bound. Overexertion causes breathlessness and anxiety. We are trying to effect this ourselves and the oxygen is proving the most problematic. At 12 liter flow, getting enough oxygen is a major technical issue if moving by vehicle. We're talking a 3 day trip with a stop halfway in Watsonville for a day. [more inside]
