CHAPTER 30 (part 2)

"Alright doctors!" The class immediately fell in
full silence when Amber walked in confidently into the class using a neat blue plaid shirt and black jeans Tara prepared for her. These kids were technically not doctors yet, they were med student with fresh brain and curiosity and the prestige to be called 'doctors' would boost their spirit to learn.

"Today, we are going to learn about tension
pneumothorax and what to do when you find
this condition. I will explain it in the easiest
possible way for you to understand. Of course
there are many videos about it on YouTube or
whatever med sites on the Internet. But today,
I'll give you a very rare chance to see it live."

She smiled at the enthusiastic murmur.

Her residents brought in two large grey boxes and put it on the table.

"Okay, lets see. Ah! Five of you," she pointed
the first row to come forward next to her. "Put on your gloves, please," she ordered. "Now, we're going to find out what's in this thing," she tapped the plastic box. "Open it," she said to the male participant.

"Oh my god!" He gasped. "It's a lung!"

"It's not a lung. It's a pair of lungs." Amber laughed. "A really fresh pair of lungs. Now don't be too surprised, you already seen it before, right? Anatomy skills lab?"

"It's a breathing dead lungs in a box," one of
them said as a matter of fact.

"Yeah, we never see dead lungs breathing in a
box before."

"Now you see it." she shrugged easily. "And in this
other box, is a not really fresh pair of lungs."

"Can I touch it?" asked the thick glasses young
girl.

"Sure you can, but after my explanation, okay?"
Amber smiled friendly. "Of course as you can see
these lungs are not breathing by themselves.
We use this endotracheal tube connected to the
ambu bag to push oxygen into the lungs. Both of
them rise and down nicely, right?" The students
nodded in agreement.

"Let see the first lungs," she took the organ out
of the box and put it on the tray. "Not injured
everybody. Go on examine it." The five students
carefully lifted it up and down to find any
abnormality.

Five of them nodded.

"Not injured, right? Okay, now pay attention. I
will use this plastic bag-imagine it as the chest
wall, okay?" She wrapped the lung using the bag
and asked her resident to pushed the ambu bag.
"Look at it. What do you see?"

"Bag is collapsing with each ventilation." the
straight haired young girl answered. "It expands
without trouble."

"Right! That is correct. Now we move on to the
second lungs. What do you see?"

"There's a cut, here."

"Okay, this one is an injured lungs. Lets put the
bag and push. What do you see?"

"Wow, the bag is keep on expanding." the tall
man stunned. "But isn't that mean that the
lungs is going to be recessive? There's too much
pressure. "

"Aren't you guys smart?! Hah!" She clapped her
hands excitedly.

"If the lungs is injured, air will leaks into
pleural cavity. So the bag will not collapse with
expiration instead itll trapped the air more
with no way out. So then the question is, how to
reduce the pressure?"

A handsome guy raised his hand to answer.

"Yes, Mister?"

"Pascal. Pedro Pascal, doctor."
