The half-fast fall colors tour had its second incarnation of the season. We postponed due to weather and it was the right choice.
After a leisurely breakfast to let it warm up a bit, we headed off through the former Badger Army Ordnance Works, now being restored as prairie by multiple owners. This version of the route took us on a few miles of dirt road, sometimes with gravel, sometimes with scattered rocks, sometimes just rutted dirt with fallen leaves to hide the ruts. We met a car. They must have been lost, because we saw them again minutes later, going the other way.
After lunch we rode past a stone silo and some more stone work that always reminds me of this scene from “The Princess Bride”.
The afternoon featured hills, as we are on the edge of the Driftless Area.
It remained warm enough for hors d’oeuvres and wine on the back porch of the cafe overlooking the Wisconsin River.
After a day of rest we joined the last Bombay Bicycle Club ride of the season. The ride started 10 miles from my house and was only 40 miles, so I could ride from home to meet them. It has always seemed weird to me to drive my car somewhere in order to ride my bike. It makes sense after work (see Wednesday Night Bike Rides) when you want to get somewhere out of town before it gets dark, but on Sunday morning, with a meetup time of 10, there was plenty of time to do the laundry and get to the start point.
There was a car show going on at the meet point, with a bit of everything (including a matte black Lamborghini roadster – looking at pictures just now, I’d say it was an Aventador – nothing like a stealth car that can go >200 mph [>350 km/h] and 0-100 km/h in ❤ seconds [Ed. note: some browsers change less than 3… < 3… to a heart emoji, sorry]). There was also a Model A Ford and some Chevy IIs, later renamed Nova – another good story, as the Nova had poor sales in Mexico and GM didn’t know why until someone told them “No va” means “it doesn’t go”. Major corporations then learned to check languages other than English before they named cars and other products, and also to use made-up words.
It was 60 degrees (15.5 C) and warmed up to 75 (24 C) as the day went on. We rode out into a brisk headwind and returned into that same wind, as it was a circular route. We seemed to get short-changed on the tailwinds today – but if miles are equal, time certainly isn’t.
Tomorrow may be the last warm day for the year (unless the front comes early), with the temperature dropping 2o degrees by Tuesday and that could be it for warm weather for this year. Then comes the dark and wet season until snow comes to brighten things up.
Happy birthday to an 80 year old who helped introduce me to cars. Luckily, I outgrew that and turned to bikes;) since the Italian car mentioned above costs about a half million dollars more than my Italian bike.
With that in mind, we decided that the fall color ride, being one of the highlights of our year, might be twice as fun if we did it twice. On Tuesday, October 18, we decided to put that to the test. Finding two available dates was surprisingly hard for a group that is mostly retired. [By “mostly retired”, we don’t mean like “mostly dead”. We mean that most of us in the group are retired.]
And so, on Tuesday morning, after a breakfast that couldn’t be beat, we headed off into the sunrise. It was a fine fall morning…
Or maybe we didn’t. It snowed a bit on Monday, with a temperature that never got out of the 30s (<4ºC) and winds that stayed in the teens all day. The forecast for Tuesday was more of the same so, one by one, folks found other ways to spend the day. We rescheduled for a day when it is supposed to be about 40 degrees (F) warmer.
What to do? I made my own breakfast and coffee instead of going out with the gang. On the road early, temperature right at 32 (0 C), a strong wind making the wind chill some number I don’t care about. Why do I own warm cycling clothes unless it’s to ride when it’s chilly?
It was a beautiful morning. The colors are past their peak, but don’t tell that to the maples in their Serrano chili red, or maybe it was Ferrari red, or maybe crimson or scarlet or a red with no name. It was a red that made the sunlight different when I passed those trees; a red that made the sky around it bluer; a red that made me realize I don’t know what red means.
Alas, none were close enough for a good picture. As the kids’ book detective Cam Jansen would do, I said “click” and took a picture that only I can see.
One of these days, we will head out for the final group ride of the season. You’ll read it here first (since you won’t read about it anywhere else, ever).
I just finished my last tour of duty on the COVID-19 units – not because the pandemic is over (it’s not) but because I have 5 more weeks to work and will not have another rotation in that time. (Dog willing.) When I hang up my PAPR (Powered Air-Purifying Respirator) this week, I hope never to pick it up again.
We want this pandemic to be over, people are beginning to act like it’s over. We can pull the wool over our eyes or we can face the music. Numbers are down, but ask the dying what they care about numbers.
I started the week with someone who went to a family gathering for Easter. A guest invited by one of the family had driven halfway across the country to join them, picking up COVID-19 along the way. The whole family is now infected. I think they will all survive. Another patient went on palliative care that first day. While COVID-19 will not be the only cause of death, it will certainly be a contributing factor.
Another patient told me they felt “crappy” but could not explain further – not painful, not short of breath, not nauseated, just crappy; also disappointed in their lack of progress from the orthopedic injury in addition to COVID-19. I went in to work the next morning to find they died 16 hours later – 20 minutes before my arrival to work.
A fourth patient told me of a near-death experience. They had a heart arrhythmia and were about to undergo DC cardioversion (pretty much the same as defibrillation of a newly-dead person, or as Miracle Max might say, mostly dead). As doctors were preparing, my patient announced they were receiving a phone call from a (long-dead) parent. As they tell it, the doctor began the procedure instantly, not waiting for the anesthesia to take effect, later explaining to my patient that he thought their death was imminent. The patient says the doctor told them that, should they get calls from dead relatives, they should not answer.
The story was told, not to be entertaining, but in a tone of terror. This person was terrified of death and still fears their death is imminent. With COVID-19, I am in no position to doubt. I received my fourth vaccination at the end of my shift.
We’ve hinted about this topic for a while. Let’s get down to brass tacks and talk about frostbite. Remember I’m not a doctor, but I play one on TV. Nothing in this blog should take the place of adequate medical care.
As usual, we’ll start with a story. I was 13. It was a Sunday morning in January, about 5 AM. The temperature was about -15 F (-26 C) with a 20 mph wind (windchill about -40). [While we didn’t know about windchill in those days, and I’ve been known to pooh-pooh it, it is a real factor when it comes to freezing flesh.] I was heavily laden with newspapers and stopping at the first house. The bike was too heavy to make it up the steep driveway, so I parked at the foot of the hill and jogged up with the paper. At the front door I heard a crash. I turned and looked down the hill to see my bike tipped over and newspapers flying about. I ran down and hastened to pick up papers, trying to stuff them back together. With heavy mittens I didn’t have the needed dexterity so I tossed the mittens aside and worked frantically against time and the wind. I’d gotten all 109 remaining papers back together (not all had blown apart) and reloaded on the bike. No more pages were flying around. I noticed my fingers weren’t cold, but they were stiff. I bit one and didn’t feel anything. Under the streetlight they looked white (and I don’t mean Caucasian, I mean really white).
With a couple of hours of outdoor work ahead of me I knew I had to do something or lose my fingers. I found a house with lights on and rang the bell. They knew me as their paperboy, but they also knew my older brothers from when we lived in this neighborhood (as tenants of the person whose house I’d been delivering to when this happened).
They invited me in and let me call my parents for a ride, then I went into the bathroom to thaw my fingers under running water. The pain was excruciating as blood returned to my fingertips – but I kept all my fingers and I delivered all of the papers on time – the next 100 or so from the back of a car. Fast-forward 35 years and I found myself working in a burn unit, treating people with frostbite.
Windchill is definitely a factor with exposed skin. Wednesday it was -12 degrees F (-24 C). It was calm so there was no windchill. I rode to work at 15 mph so, relative to me, there was a 15 mph headwind and therefore a windchill of -35 degrees. If you ride in winter, remember it is always windy.
What do you do for frostbite? The most important step is prevention. When it is really cold, cover all skin. The Cleveland Clinic says 10 minutes at -10 F is long enough to get frostbite. Wear mittens, not gloves. Your fingers help to keep each other warm. If they still get cold, you can make a fist inside of the mitten. A bit of anatomy will help that make sense.
The main takeaways from the picture are: 1) the blood supply to your hand (like your brain) is redundant. Notice that the radial and ulnar arteries join to form an arch and the blood supply to your fingers comes off of that arch. Thus, even if one artery is injured, your fingers get blood; 2) there are two arches – a superficial and deep arch. (Okay, three in this image, including the unlabeled one – I’ve never seen that third arch depicted and I haven’t dissected a palm lately to look for it. If I do, I’ll post an update.) This gives further redundancy; 3) the arteries to your fingers run up the sides. If your fingers are separated in gloves, more surface area is exposed to allow more heat to escape. Conversely, if your fingers are touching, they keep each other warm. Also, the pads at the tip are the last place to get blood – the vessels are pretty small by that point; 4) due to the multiple vessels running through your palm, if you tuck your fingers into a fist, the tips are warmed by the palmar blood.
As an experiment this week, I wore my big mitten from Empire Wool and Canvas Co on one hand. On the other I wore various liners under the mitten: 1) a thin polyester biking liner glove; 2) a full-fingered insulated biking glove [a spring and fall glove]; 3) a nitrile exam glove. While a glove was handy when I had to work locks and keys and mount a pannier, the mitten alone was warmer while riding. When my fingers got cold I had enough space inside to make a fist and warm them up. They warmed quickly due to direct skin-to-skin contact.
[An aside here: Clearly, the brain and the hand are important structures in humans. With the Circle of Willis in the brain and the palmar arches in the hand providing redundant blood supplies, our bodies have gone to great lengths to protect these structures. Think about that.Discuss among yourselves.]
Toes are also subject to frostbite. I could argue that they are easier to live without, but instead I’ll argue that you should protect them. Wool socks, liner socks if it’s really cold (I use silk for less bulk), and warm boots are essential. The longer you are out, the greater your chances of losing parts. Consider hand and foot warmers (battery-powered, or chemical pads that release heat when exposed to air).
You’re out in the cold. You notice your fingertips are getting cold. DO something! Get inside if possible. Move (your body in general, your hands and feet in particular). Get your hands out of the wind. Make fists. Stick your hands in your pockets (with mittens on if possible) or in your armpits (without mittens). (Zip your jacket back up to preserve core heat.)
Did you fail to do any of those and your fingers stopped feeling cold? Did they stop feeling anything? If you squeeze your fingertip, is it hard and you don’t feel it? Are your fingers stiff? Warm them up!
Do NOT rub snow on them. Do NOT run hot or cold water on them. You are trying to rewarm them to body temperature. Use water about that temperature. Feel it with an unfrozen body part (like an elbow or another person’s hand), because your frozen fingers can’t tell how warm it is and you don’t want to burn them on top of the frostbite.
When the skin has turned white and the tissue has frozen, there is no blood supply. The tissue will die if not rewarmed. As it rewarms, it will hurt. Deep frostbite can cause lasting damage. If in doubt, get to a doctor, preferably a regional burn center.
Deep frostbite will blister. The skin will turn purple. It will look like a bad bruise. That is essentially what you have – damaged and leaky capillaries that allow blood to flow into the interstitial spaces and cause the skin to look purple; clots that prevent flow into and out of small vessels. From there, one of two things happens: either it slowly returns to normal color, or it turns black, mummifies, and eventually falls off (which is known as auto-amputation). I am not going to include pictures of any of this. If you really want to see that, Dr Google will show you pictures of what happens when you get deep frostbite. Suffice to say that I have worked with people with fingers that were amputated at the first joint, leaving nubs (which can be surprisingly functional, but I don’t recommend you try it), and with people who lost their fingers (and legs, for that matter) entirely. I’ve seen it so you don’t have to.
Deep frostbite requires a doctor’s care – in a hospital. For the first 72 hours we encourage the patient to move their fingers actively but, unlike burns, we don’t move them passively – that could cause further damage to deep tissues. After initial warming, the fingers will have to rewarm from the inside out. Medications can improve circulation and re-establish blood supply before tissue dies (like the treatment to cerebral arteries after a stroke, or in the lungs after a pulmonary embolism). The body will scavenge dead tissue. That process can cause further complications that you can’t manage by yourself.
Your fingers may stay purple for a while. The doctor will wait for them to “declare themselves”. It is not always clear what tissue will survive and what is dead.
Doctors do not want to amputate fingers that are only “mostly dead”. They don’t want to amputate dead fingers but leave some dead parts behind. They also don’t want to amputate too far and take parts that will heal. Once the fingers have “declared themselves” they will take the dead part and cut back to healthy, bleeding tissue so the residual limb will heal. Then the therapist will work with you to help regain function with partial fingers, help you learn to compensate for what is lost, and help reshape the residual fingers.
Obviously, you don’t want to have first-hand knowledge of most of this. That’s what I’m here for – to convince you to care for your body and keep all the parts.
