The lockdown has been eased...

#COVID19 case numbers and mortality are coming down

But the crisis isn’t over. There will be second wave

We have an opportunity here to help save lives

#AllWeAskIsWearAMask

There’s been some controversy around masks.

Some national health authorities recommend them. Others don’t.

But there is an interesting graphic here demonstrating countries where people regularly wear masks have lower incidence of #COVID19 Image
There’s evidence from world renowned experts like @trishgreenhalgh suggesting face masks may reduce population risk of infection

So all we are asking today is that you think about how face masks can protect you, but more importantly, others around you. Image
Face masks you wear do not need to surgical grade masks. Let alone respirators

Simple face coverings made of cloth will do

Just do not touch or fiddle with them when out & about.

Wear them if you’re going to be somewhere a 2m distance is impractical- say public transport
Cloth Face masks aren’t the final solution.

But they’re easy, simple to use, can be reused after washing, and are essentially risk free for most people- unless you have pre existing respiratory conditions like asthma.
Recently, England and Scotland have both recommended wearing face masks

It’s a simple intervention, which can help save lives.

Face masks are easy to make, and easy to wear.

Here’s some tips from the BBC Image
Here we have @trishgreenhalgh explaining why non medical face masks are useful in public places. They contribute to everyone’s safety!

I’m going to tag this as a little tutorial for @MichaelYeadon3 who keeps saying that there’s no problem from the suppliers of medical ‘gasses’

Most hospitals in the U.K. run their O2 supply from a Vacuum Insulated Evaporator (VIE)

frca.co.uk/article.aspx?a…

1/n
This VIE is essentially a large thermos flask/ vacuum insulated cylinder at -180C
O2 is supplied from (typically) BOC in liquid form; when required, allowed to evaporate into gas, & supplied to hospital outlets.

Most hospitals have a VIE big enough to meet their needs

2/n
The problem is the pipes

Most ~12 bed ICUs have pipes that allow ~400L/min flow

This is Ok because most ventilators don’t use >20l/min; giving useful buffer capacity

Modern non invasive ventilation systems- CPAP, NIV, and High flow nasal Oxygen (HFNO), however, need more

This may sound gruesome to many

But last night, I read the ‘drowning rats experiment’

Rats were put in water. They normally swim well. So the surprise was they seemed to drown quickly. Image
Then the researcher reflected: perhaps there was an imponderable here.

If you think there’s no solution, fight or flight is not an option. So you give up. Image
Then, you think again, when con fronted with ‘HOPE’ these rats kept swimming for hours - 100x more than in the first set. Image

Anyone else irritated by the fact that the useful but dull stuff seems to get very little attention

New ICU Trainees want to know about how to manage refractory hypoxia, ventilator settings for asthma

Not relevant for anyone that’s not going to make icu a career

1/n
What almost every Dr working in hospital needs to know about is

Types of O2 delivery devices, limitations, variable vs fixed performance

In the last year, I’ve kept some numbers, and 86% had never heard of Peak Inspiratory Flow Rate. Which is not their fault, obv

2/n
For anyone that’s a medical trainee, they need to properly understand NIV and CPAP

Indications, evidence base, but also how to set it up.

I saw him first on my evening rounds.
A tall, strong man around 60, He’d just come back from major bowel surgery

An epidural top-up helped with pain, and put a smile on his face, and his wife’s

They were very pleased at the lack of a colostomy too

Around 2AM, he went wild.

Trying to pull out lines, hit nurses, run away

Screaming we were going to catch him, kill him and he wanted to go home

He was a danger to himself- was on strong medication to keep his blood pressure up, and had lines and drains

2/n
Took 4 people to hold him down so he could have sedation

ICU delirium is unfortunately very common, and we don’t always know what causes it. However, some risk factors are known- sedation, sleep disturbance, noise, being unwell, bright lights at night, etc.

Today I’m going to talk about something uncomfortable

Do you have friends or colleagues who don’t have children?

Here’s some things not to say

Thread...

1/n
When are you going to start a family?

We are a family... and it’s none of your business

Family ≠ children

2/n
How old are your kids?
Do you have kids?

Believe me: if someone has kids, they’ll tell you within 15 min. If they haven’t said anything: stay out of it.

This is my day of being horrified

Having lived out of India for ~15 years, I had no idea this wasn’t crime fiction

But it seems it’s true!

Read on about ‘Narco-Analysis’ and role of Drs in judicial process

1/n
The World Medical Association says Drs should not be involved in judicial executions

This is probably why we see so many reports of execution by injection going wrong in 🇺🇸

2/ Image
However, from talking to friends, and documentary evidence, it seems Drs are required to be present at execution by hanging in India.

@IMAIndiaOrg doesn’t like this.
