Oxygen testing

“If oxygen might help with chronic fatigue, as it has helped you,” a friend asks, “how do I get on oxygen?”

Complicated answer.

First of all, one of the things that is not clear, is what recovery looks like. I think I’ve had low grade chronic fatigue for the last 7 years compared to my “normal”. Now, will I get off oxygen? I don’t know. I am hoping for September but it may be that 7 years of low grade hypoxia means I have lung damage and no, I won’t get totally off oxygen.

They have apparently recently made the guidelines for oxygen more stringent. I sort of missed that update, even though I just recertified in Advanced Cardiac Life Support. You now have to have an oxygen saturation that goes to 87% or below. It used to be 88.

Now, you can test this at home with a pulse oximeter. In 2005 after the influenza, I held my saturations but my heart rate would go up to 135. Which means that I walked across the room very very slowly because a heart rate of 135 sustained does not feel good at all. Normal is 70-100 beats per minute. You can measure pulse with just a second hand, number of beats in a minute. For oxygen saturation, you need the pulse ox and it will measure both heart rate and oxygen saturation.

So: measure pulse and saturation at rest first. Write them down.
Then walk. I usually send patients up and down the hall three times then sit them down and watch the pulse ox. In some, the heart rate jumps up. If it’s over 100 and they are getting over pneumonia, I don’t want them back at work until it is staying under 100. Or if sitting they are at a pulse of 60 and then walking it’s 95, well, I think that person needs to convalesce for a while yet. They can test at home.

As the heart rate returns to the baseline, the oxygen level will often start to drop. Does it drop to 87? Describe the test to the doctor and make sure the respiratory technician does it that way and also they should do pulmonary function tests. Mine were not normal.

Now, what if the oxygen doesn’t drop to 87? We are not done yet. What does the person do for work or do they have a toddler? If they have a toddler do the same test carrying the toddler: they sit down, exhausted and grey and this time the oxygen level drops below 87. If they do not have a toddler, do the test with two bags of groceries. Or four bricks.

When I did the formal test, the respiratory therapist said, “Let’s have you put your things down so you don’t have to carry so much.”

“I’d rather not.” I said, “I want to be able to walk on the beach, so I need the two small oxygen tanks, my bird book, camera, binoculars and something to eat.”

“Oh, ok,” she said.

So I did the test with two full tanks of oxygen, small ones, and my bird book and etc. I dropped like a rock loaded. I think I would have dropped not loaded but perhaps not as definitively. Still hurts to carry anything, even one tank of oxygen.

We are making a mistake medically when we test people without having them carry the groceries, the toddler, the oxygen tank. My father’s concentrator is pre 2013. It weighs nearly 30 pounds. Now they make ones that weight 5 pounds. Huge massive difference.

Good luck.


Walking the beach with a friend a couple of mornings ago, I keep finding shells with a dark marking in the center of the interior and nice shiny interior. Then I find a shell with the other half attached. The other half has a hole in it.

I look it up. This site comes up: http://www.bily.com/pnwsc/web-content/Northwest%20Shells.html. Wow. We filter through it and the shell is in the family Anomiidae. Specifically Pododesmus macrochisma, aka Green False Jingle. It attaches to rocks or other jingles or whatever through the hole. Then it disguises itself. The outside of the shells I found was diverse, some with barnacles. I found a young one, pink, and the radial ridges are visible on the shell.

Cool! Next I tried to identify the two different kinds of chitons. Uh-oh. There are LOTS of chitons. I run out of air very quickly. I will save the chitons for another day. I also returned two sea cucumbers to the sea. The second one scrunches up when I pick her up with a piece of seaweed. When I put the second one in the water, she relaxes. The first one was probably already dead.

Letter to a younger friend

After my mother died I really struggled, partly because I was in the midst of a divorce and felt like a massive failure. I did not like myself. But I kept thinking about my mother and how much she hid: and eventually I thought, you know, I love all of my mother. Even the stuff she hid. If she is lovable then so am I.

What is lovable in your parent? And would you miss her/him if she/he were truly gone?

That is the hard thing for me, that I couldn’t think about that until she was dead. With my sister, I thought about it before she died and changed how I behaved and let her know when I disagreed with her. Even though she had cancer.

Isn’t the greatest gift we can give each other loving honesty? I love you and I disagree with you and I am not going to do what you want just because you (are my mother/are my father/have cancer/have emphysema/want it/are dying). Isn’t the greatest gift to be ourselves and take the flack for it?

Cucumber love is a poem I wrote more then ten years ago about dropping the exoskeleton that we wear for society’s and our family’s approval. It takes courage. You can drop a little piece at a time and let them get used to it. And yes, some people may reject you for good. That is their choice. But you have to ask yourself then, did they ever really love you or did they only love to control you?

Cucumber love

They say they love you
And they do

Sort of

One day you find yourself
Wearing a construct
An exoskeleton
You can move
See out

You built it slowly over years
Because that’s what you were told to do
You wanted to be loved
It made you feel safe

There is praise
Or at least pressure to keep it on
You may not have known it was there
And slowly begin to feel
Who you really are
Awaken to the shell

One day you slip out

They are still saying how much they love you
To the empty construct

You watch bemused
For a while

You say “That isn’t me.”
“Of course it is,” they say

“I’m over here,” you say

Shock and outrage
“That’s not you!
You’ve changed, you’re depressed
Confused, manic, gone out of your mind!”
Off the deep end

You might even go back in to
the construct for a little while

But now you’ve tasted freedom
You won’t be able to stand it for long
You will be out soon

Some people will see you as you really are

Some people will tell you they still love you
But as they say it to the construct
They act as if you’re still wearing it
They still think you love cucumbers
Though you ate that dish once to be polite
They hold the construct in their minds
Even after you’ve destroyed it
And behave the same as they ever did

As you walk away
You will wonder who they loved
