so say you have a lil 4 week old baby who needs his patent ductus arterius closed. So he has it closed in cardiac catherization in the neonatal intensive care.
In general - compared to a normal infant, where would this one have a higher PaO2 (partial pressure of oxygen)?
WELLL
Let’s think about it
so a patent ductus arteriosis connects our aorta to our pulmonary artery (oxygenated blood is going into our UNOX blood because of pressure differences)
SOOO
obviously the pulmonary artery is going to have higher oxygen potential then it should
You’re not being dramatic; school shootings is a big worry. And while I don’t believe you should drop out - I do think you should consider talking with a school counselor and school therapist about your worries
It’s like grounds extremely sacred to me have been attacked. I’m going to unload again, but my aunt and uncle got married at a chapel on MSU’s grounds, on the day Megan died. On each altar was a white rose for each of us, and white roses just…strike a chord. I’ve been there multiple times.
a licensed therapist/mental health professional would be able to help you address your fear and they’d be able to help you find ways to make it more manageable
it’s not going to magically fix anything but it can help it not impact your day to day life as much
At least you have a seat. Also, I prefer baths, as when I get out of the shower, I’m freezing. At least with baths, I can soak in the warmth. Yes, I know I’m soaking in my own juices, leave be be.
I just don’t want to snap my neck, thanks. My mom got me some sort of bumpy thing so I don’t slip, and I swear, I will trip over one of those bumps. Somewhat unrelated, but I was using a cane, and the tip got stuck on a bump, and was shoveled into my abdomen, basically giving me the Heimlich. I thought those things were supposed to help people like me!
so say you have like a 62 yo man who comes into the office with LEFT arm clumsiness. In his physical exam; he has motor weakness of both his LEFT ARM AND LEG.
His speech be slurred
He has a drooping of his LEFT LOWER FACE
when he “flexes” his left arm, there’s resistence for a second and then it suddenly releases as he continues to flex
He’s having left sided issues - meaning his right brain is affected
Not that it helps us since all the answer choices are on the right but just a good though process to have
Let’s talk through what all of those spots on the brain are
A. Caudate Nucleus: Extrapyramidal issues
B. Internal Capsule: Motor cortex runs through here
C. Insula: Emotional experience issues if damaged!
D. Putamen: Extrapyramidal issues
E. Globus Pallidus: Extrapyramidal issues
so what this patient has is Clasp knife spacisity (resistence followed by SUDDEN release) adn that is usually seen with UMN lesions. It usually happens because a LACK of Upper motor neuron inhibition.
UMN lesiosn can affect any part of the motor system, which runs from the primary motor cortex through the internal capusle TO the brainstem and spinal cord
SOOOO pts with an internal capsule stroke can have both SENSORY and MOTOR but usually it’s motor
