Nitrogen Washout Puns

I understand that the volume of pure oxygen exhaled = anatomical dead space, and the volume mixed with nitrogen = alveolar. However I can’t find any source explaining why nitrogen presence signifies alveolar air, since it (to my understanding) is not involved in gas exchange. I could understand if CO2 was used, as this signifies occurrence of gas exchange in that unit volume of air exhaled. But if a unit volume of air has mixed with nitrogen, how does that tell us whether it was in a conducting airway or not? Thank you

Is hyperoxygenation and nitrogen washout of patients with simple pneumothorax linked with a decreased duration of healing, decreased complications and/or decreased progression; or is it no longer recommended? (Obviously not talking about washout prior to altitude)

I'm a paramedic student and currently in a conversation with some paramedics who disagree.

The body has to have its own natural PEEP in order to keep the alveoli open in the lungs, right? I recall hearing from one of my lectures that the body naturally has a PEEP of roughly 5cm H2O, yet I can't find anything online to back this up, aside from air-trapping examples.

I know that they are kept open with surfactant and residual air/nitrogen. In cases where washout occurs, the alveoli collapse and mechanical, extrinsic PEEP is required. Is the combined effect of the surfactant + residual air creating this total "PEEP"-like effect?

The opposing view is that the lung pressure deflates to the local atmospheric pressure, and the ribs and pleural cavity don't allow the lungs to fully collapse from a structural perspective, instead of pressure.

Thanks for any response

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Do your worst!

I'm surprised it hasn't decade.

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.

I said "hey look, an escaPEA"

No one near me but it didn't half make me laugh for a good hour or so!

Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂

It really does, I swear!

Buenosdillas

They’re on standbi

Pilot on me!!

Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.

This sub is mostly just NSFW puns now.

If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.

Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.

When I got home, they were still there.

What did 0 say to 8 ?

" Nice Belt "

So What did 3 say to 8 ?

" Hey, you two stop making out "

I won't be doing that today!

This morning, my 4 year old daughter.

Daughter: I'm hungry

Me: nerves building, smile widening

Me: Hi hungry, I'm dad.

She had no idea what was going on but I finally did it.

Thank you all for listening.

You take away their little brooms

There hasn't been a post all year!

Previously: Bhishma Part 1

***

Nkechi-25 sits across the table from Dr. Ilya Blake, her luminous eyes darting around the sterile, featureless room.

"Why am I here, ma'am?" Nkechi asks politely. She feels uncomfortable out of her armor. She feels light. Vulnerable.

Blake clasps her hands and rests them on the table. "You've been classified as 'presumed dead'. Your fireteam is fine, but they will never see you again."

Confusion, disbelief, and anger washed through Nkechi like a firestorm. "Why, if I may ask?"

"You're going to train the next generation of Bhishma Golems."

Nkechi stares at Blake.

"I-I thought Golems were being created presently, ma'am?"

Blake smiles humorlessly. "Golem production ceased three years ago. Due to both legal reasons and lack of qualified subjects, we were forced to stop."

Nkechi feels cold. She never thought that she and her comrades would be both the first and the last of their kind.

"If you were stopped, then why are you trying to continue, ma'am?"

Blake takes a shaky breath. "Desperate times call for desperate measures. The first generation of Golems are too valuable. The entire system knows about our enhanced Exo supersoldiers. They're things of legends. So sending them on suicide missions would be a massive blow to morale to both the entirety of the system and our military."

The doctor pushes a data pad toward Nkechi. She accepts it and scans through the file presented. "New training protocols have been outlined as well as the improved augmented Exo chassis. We've... learned... from the unfortunate medical processes that were administered to previous generations."

Nkechi shudders as she remembers the feeling of her entire nervous system being torn from her body. She remembers the feeling of liquid nitrogen streaming through her veins, and white-hot blades searing through her brain as her body was forced to adapt to her new chassis, accelerating her reaction time, strength, and speed. She remembers the horror of the Golem 1's, the unfortunate subjects tearing themselves limb-from-limb, sobbing as they do so.

The towering Exo reads the files, slowly grasping the intent of this new generation of Bhishma Golems. Their chassis and augmentations were a quantum leap ahead of what she received. This new generation would be even faster and stronger than her. The survival rate was much higher as well, nearly ninety five percent compared

Nothing, he was gladiator.

It’s pronounced “Noel.”

After all his first name is No-vac

What, then, is Chinese rap?

Me grabbing a soda from my (what I thought was) half full 12pk...

Notices there's only 2;

Me: "Awe man... This is a damn bird box!" Her: "What the hell does that mean?!" Me: (Pulls both cans out & shows them to her) "It's only got Toucans."

I'm not ashamed to admit the look on her face was glorious.
