cardiac arrest is when the heart stops - abruptly and with little warning
this is different than a "heart attack" when there is a blockage to a coronary artery, and USUALLY the heart doesn't stop
3/5
cardiac arrest is 100% fatal UNLESS actions are taken immediately - those actions include CPR and the use of a defibrillator
4/5
it's really important to start CPR right away if someone suffers cardiac arrest.... the chance of survival falls by 10-15% for EACH MINUTE that cardiac arrest isn't treated by these actions
key that ALL OF US learn CPR & how to use an automated external defibrillator (AED)

praying for Damar Hamlin and his family - no matter what the cause, cardiac arrest is a critical medical problem
post script - to watch a 90 second video to review the basic actions of CPR and AED use, check this out:
post script #2 - I did a free lecture series on cardiac arrest for Coursera many moons ago, here's a link for more cardiac arrest content if interested:

now, before I begin: we cannot yet say if Mr. Hamlin will recover. He has a long and difficult road ahead.
But what is medicine without hope?
As an ER doc, I couldn't do my job without it.... so let's learn from these survivors:

1. FABRICE MUAMBA - 2012
A soccer player in the UK, Mr. Muamba collapsed at age 23, during a game. It was observed that he "fell like a tree trunk. He didn't put his arms out to break his fall, or anything, he just dropped."
in my first thread earlier tonight, I briefly explained CPR.
When CPR is successful, and heart function is restored, patients require specialized ICU care to support organ and brain recovery - this is known as POST-ARREST CARE.
It is slow and careful work.

One of the keys to post-arrest care is TARGETED TEMPERATURE MANAGEMENT (TTM) - the use of technologies to avoid fever and precisely control body (and hopefully brain) temperature.
It can look like this - cooling pads hooked up to a coolant machine:
1,000s of pregnant women each year in the US are diagnosed w cancer. These include breast ca, rectal ca, melanoma.
Treatment may require radiation, chemotherapy. But here's the problem....
radiation & chemo can cause great fetal harm in up to 15%-20% cases
what to do?
(3/8)
imagine: you're a pregnant women, excited to have your 1st child. You receive terrible cancer news. And you are told that you need chemo NOW - or you risk the cancer spreading.
But you are told chemo has a big chance of harming the fetus.

Ectopic pregnancies, sometimes called "tubal pregnancies" are when the fetus is growing in the wrong place.
A fetus should take root in the uterus, where it can grow safely. If it gets stuck elsewhere, that's an ectopic.
It's super common - 1 in 50 pregnancies!
(3/11)
many women have no idea that their pregnancy is ectopic.
One day, they have abdominal pain and/or vaginal bleeding, and they go to the ER - and an ultrasound confirms it. It's a serious emergency that ER providers see ALL THE TIME.
