Cardiac arrest, also known as Sudden Cardiac Arrest, is when the heart stops beating suddenly. The lack of blood flow to the brain and other organs can cause a person to lose consciousness, become disabled or die if not treated immediately.
The terms ‘heart attack’ and ‘cardiac arrest’ are often used interchangeably, but these are two different heart conditions.
A heart attack occurs when there is a blockage in the arteries that stops blood flow in the heart. Due to the lack of blood and oxygen flowing in the heart, the heart muscle tissue will become damaged. Heart attacks can increase the risk for cardiac arrest because heart attacks can alter electrical signals in the heart.
CPR – or Cardiopulmonary Resuscitation – is an emergency lifesaving procedure performed when the heart stops beating. Immediate CPR can double or triple chances of survival after cardiac arrest.
If someone experiences cardiac arrest, they need immediate treatment to increase the flow of oxygen-rich blood to their organs. CPR is the compression over the chest to manually pump a patients heart. Rescue breaths are preformed to provide oxygen to the body.
During CPR, proper hand placement on the lower half of the sternum is crucial. Placing hands over the sternum ensures effective chest compressions directly above the heart, optimizing blood circulation throughout the body.
According to the American Heart Association (AHA), the overall survival rate for out-of-hospital cardiac arrest is around 10%. However, survival rates can be improved if bystander CPR is started immediately. Studies have shown that bystander CPR increases the chances of survival for someone experiencing cardiac arrest. In fact, the AHA reports that survival rates increases to 40% or higher when bystander CPR is performed promptly. The surival rate is between 24% and 40% for those that happen in the hospital, according to the report published online in the Emergency Medicine Journal.
CPR is preformed between 100 - 120 beats per minute. Famously Staying Alive by the Bee Gees is the same beat. A large list of songs with the correct BPM can be found here
The American Red Cross gives the following list of steps to asses if CPR is needed and how to preform:
1 CHECK the scene for safety, form an initial impression and use personal protective equipment (PPE)
2 If the person appears unresponsive, CHECK for responsiveness, breathing, life-threatening bleeding or other life-threatening conditions using shout-tap-shout
3 If the person does not respond and is not breathing or only gasping, CALL 9-1-1 and get equipment, or tell someone to do so
4 Kneel beside the person. Place the person on their back on a firm, flat surface
5 The American Red Cross CPR guidelines recommend 100 to 120 chest compressions per minute, 30 at a time. Remember these five points:
Hand position: Two hands centered on the chest
Body position: Shoulders directly over hands; elbows locked
Compression depth: At least 2 inches
Rate of compressions: 100 to 120 per minute
Allow chest to return to normal position after each compression

Give 2 breaths
Open the airway to a past-neutral position using the head-tilt/chin-lift technique Pinch the nose shut, take a normal breath, and make complete seal over the person’s mouth with your mouth. Ensure each breath lasts about 1 second and makes the chest rise; allow air to exit before giving the next breath Note: If the 1st breath does not cause the chest to rise, retilt the head and ensure a proper seal before giving the 2nd breath If the 2nd breath does not make the chest rise, an object may be blocking the airway
7 Continue giving sets of 30 chest compressions and 2 breaths. Use an AED as soon as one is available! Minimize interruptions to chest compressions to less than 10 seconds.

why did no one ever mention that learning to code is fun
Death to America
It’s a great time, especially if you find projects that click with your skills and interests. One of my first projects was a microtonal synth since my main hobby before that was music
Damn, I tried to make a semi-accurate NES sound synth, but the math was a trouble and I got confused doing all the sample rate stuff. But I did model part of the audio chips, badly, lol. It was a fun project, I got a dumb LoZ tune working from some file format that didn’t require me to emulate the CPU.
Oh, I made mine in Python, GC pauses be damned. Most of the math I had to do had to do with distributing pitches along an octave. Everything else was handled for me. I knew a fair amount of about sample rate and whatnot because of doing music production, but I don’t envy anyone who’s programming that logic from scratch.
Learning things is fun. Especially when its cheap or free.
Everyone so focused on making money and turning out corpo software sludge, not many people learn to code just cuz its fun :3
What programming language you using? If any, ofc hehe
just python at the moment bc im a complete beginner and python has the best combination of 1) having lots of free tutorials online and 2) appearing in job postings for jobs i actually want.
i’ve got a bunch of projects i want to build actually, so I can build up a portfolio while learning. im tryna figure out how to use the fda’s database of nutrition facts to determine which foods have the best ratio of protein/calorie so i can get swole while being vegan. i’ve also got an idea for an algorithm for betting on soccer; an app that locates the closest artwork by a given artist to the user’s location; a taste similarity score for finding people to follow on goodreads given the user’s pre-existing ratings; a property values map that shows property values by block and can show historical data on a slider; and an algorithm that summarizes 10-Ks to show figure out what evil shit corporations are legally required to admit to
idk why ive told you all this when you didnt ask lol im just excited about possibly building something useful using nothing but cOdInG sKiLls
Death to America
programming is really fun yeah! it’s like making puzzles for yourself to solve. and then you are done you’ve got your cool little things you made to use!
