Question 1

i've been at 3500 feet for 3 days. been having chest tightness and shortness of breath and oxygen says 92-95 usually 98. bp 115/75. 
i felt sick on plane too. previous heart check was good. norm chest x-ray . nobody else has low oxygen here but me.

Accepted Answer

Lung function test?: have you had a lung function test to check for lung disease?  Have you had an exercise echocardiogram?  Whatever it is, you need a pulmonary and a cardio evaluation.

Question 2

what is hypobaric hypoxia?

Accepted Answer

Altitude: Exposure to air with too little oxygen pressure, as on a high mountain or in a hypobaric chamber.

Question 3

what are hypoxia and asphyxia?

Accepted Answer

See below: Hypoxia is a lack of oxygen in the bloodstream. Asphyxia, or suffocation, is the consequence of hypoxia.

Question 4

what is hypoxia versus ischemia?

Accepted Answer

Hypoxia is : Referring to low oxygenation levels globally in the body whereas ischemia refers to low oxygen levels in localized tissue.

Question 5

explain hypoxia vs hypoxemia?

Accepted Answer

Tissues vs. blood: Hypoxia is low oxygen in the tissues. Hypoxemia is low oxygen in the arterial blood.  Hypoxemia caused by low oxygen in air (such as high altitude), low ventilation (slow breathing oversedation), lung disease or blood clots in lung. Low oxygen in arterial blood leads to low oxygen in tissues but hypoxia can also be due to anemia (less oxygen carrying capacity by blood), carbon monoxide poisoning.

Question 6

why is there cyanosis during hypoxia?

Accepted Answer

Low oxygen: Cooling slows down metabolic process of circulatory system and oxygen levels fall.

Question 7

symptoms of hypoxia , cough and dysphagia ?

Accepted Answer

? aspiration: These could all be due to recurrent aspiration.

Question 8

whats more dangerous hypoxia or hypoxemia?

Accepted Answer

Same phenomena: Hypoxia is more of a physiologic state wherein  biological tissue or organs are low on Oxygen gas.
Hypoxemia is more of a specific term for low oxygen in the bloodstream.  Just a matter of semantics.

Question 9

does hypoxia cause vasoconstriction or vasodilation?

Accepted Answer

Vasoconstriction: Low oxygen cause blood vessels to constrict.The body  is trying to  use whatever  oxygen is available  to maintain critical body functions  and constrict blood flow to others.

Question 10

what are the long term effects of congenital hypoxia?

Accepted Answer

Depends on variables: Hypoxia at birth is relative, as all babies have lower oxygen content in the womb before delivery & the slower metabolism of the unborn is able to tolerate it.After delivery, baby works to breathe, maintain their heat & blood sugar & must increase their blood oxygen content. The duration of any oxygen deprivation after delivery effects amount of injury from none to lots. It takes time to tell.
