Unit 6 - Task 1 - the one about Osmosis

"There is a youtube channel called osmosis, which is about health and medicine. I want you to watch and choose one video about an illness and/or a microbe and take some notes, as you will be presenting said illness for the synchronous session.

https://www.youtube.com/c/osmosis"

So I chose to briefly talk about Sleep Apnea and these are some notes I took:

Intro: Breathing is important

Apnea = from Greek 'apnoia' meaning breathless

Medical definition: Sleep disorder, momentarily stop breathing

Two types: Normal + Central (or a combination of both normally)

Normal, most common: some sort of blockage in the air pipes. Nasal cavity and pharynx -> laryngopharynx -> trachea

Could have multiple causes: Allergies, swollen glands, severe overbite, weight issues (common)

Central: Brain induced, cycles of CO2 lows and highs (hypo and hypercapnia)

Symptoms: Snoring and Sleep deprivation, and during the day difficulty concentrating, headaches, constant fatigue

I can exacerbate risk of heart arrhythmia and failure, respiratory issues, diabetes and even some types of cancer. I would add Alzheimer’s.

Diagnosis: Test and then a sleep study. Comprehensive polysomnogram.

Treatment: 

avoid depressants (alcohol, sleeping pills, etc.) 

Sleeping on the side

CPAP (Continuous Positive Air Pressure)

Sometimes surgery
