Can You Measure Blood Pressure At The Ankle?
Consider.
- As long, as I can remember my left foot has always been larger than my right.
- Over the last few years increasingly, my left foot has often been a stronger shade of red, than my right.
- I also know, that after my stroke a specialist physiotherapist found that my left leg was stronger than my right.
I also know that I have a strange leaky skin.
- I had my stroke in 2010 in Hong Kong and was looked after in a private Chinese hospital.
- They were very strict and measured all the bodily fluids, that I passed.
- They didn’t collect any urine, so they accused me of throwing all my water away.
- I was not guilty, as I was drinking it all.
So they fitted me with a catheter and guess what? They still didn’t collect anything.
It was evidence that my skin is not good at holding water.
So why do I want to measure the blood pressure at my ankle? Or in fact both ankles.
In my ICI days in the 1960s and 1970s, I was helping chemical engineers to understand chemical plants and reactions, by looking at flows and pressures in the various pipes of the plant or experimental rig.
But I do wonder, if the red nature of my left foot, is due to some sort of irregularity in the blood flow to my left leg.
Do Animals Lose Water In Low Pressure Weather?
I feel I do and I wrote a post called My Strange Skin, which is explained by water being driven out of my body.
So I asked Dr. Google, the question in the title of this post and got this answer.
Yes, animals can lose more water in low-pressure weather conditions. Lower atmospheric pressure, often associated with unstable weather, can increase water loss through evaporation and other physiological processes.
Here’s why:
Low pressure often means lower relative humidity, which increases the vapor pressure deficit between the animal’s body and the environment. This difference in water vapor concentration drives more water to evaporate from the animal’s body, particularly through the skin.
That’s all very sound physics.
Last night, I was woken by an intense strange itch in the sole of my right foot.
- As I often do, I rubbed the itch on the a genuine Indian rug I have on the floor by my bed, but it didn’t work.
- So I had to get up and apply a dollop of Udrate cream and rub it in.
About, half-an-hour later I got back to sleep.
Today, I got a similar intense itch in the sole of my left foot. Again it was stopped by a dollop of cream rubbed in. But this time it was Body Shop’s Hemp Foot Protector.
Does water find it easier to get out through the soles of my feet?
Exceptionally Low River Levels Raise Fears Over Water Supplies
The title of this post is the same as that of this article on the BBC.
This is the sub-heading.
Many of the UK’s rivers have hit exceptionally low levels and that could worsen in the next three months, according to the Centre for Ecology & Hydrology (CEH), raising questions over supplies to households, farmers and businesses.
These three introductory paragraphs add more details.
The warning comes after the driest spring in England since 1961, with northern regions experiencing the driest start to the year in nearly a century.
Almost all of the UK is expected to have below normal or low river levels in May, apart from the south-west of England.
The Environment Agency has said that the UK is at medium risk of drought and warned households of the risk of water restrictions.
In the 1970s, I was involved in a marginal way, in the planning of the water supply network in the UK, by the then Water Resources Board. My software called SPEED was used to solve the hundreds of differential equations involved.
Since the 1970s, I have felt, that as water supply in the UK has been fairly good, that the engineers, planners and mathematicians of the Water Resources Board didn’t do a bad job.
I don’t think, I can remember a period as long as this without rain.
I am drinking heavily to keep hydrated and I’m already today on my second bottle of Adnams Ghost Ship 0.5 % Beer.
But it just seems to go straight out through my skin, which I talked about in My Strange Skin.
I am Jewish in my father’s male line and Huguenot in my mother’s, so I have lots of ancestors, who lived in poor living conditions. So did Darwinian selection produce my leaky skin, that also heals itself quickly, in the harsh living conditions.
But on the other hand does it make me dehydrated all the time? And also create lots of red spots all over my body?
It’s not something new, as I can remember feeling this this as a child and helping my mother to count all the spots.
I hope that I will be fine, when we get some rain.
