...Hypoxia is a pathological condition in which the body as a whole (generalized hypoxia) or a region of the body (tissue hypoxia) is deprived of adequate oxygen supply. Variations in arterial oxygen concentrations can be part of the normal physiology, for example, during strenuous physical exercise. A mismatch between oxygen supply and its demand at the cellular level may result in a hypoxic condition. Hypoxia in which there is complete deprivation of oxygen supply is referred to as anoxia.

Is it possible to experience Recently went on a vacation
abroad, took a plane. There
are feelings of lethargy and
sleepiness even after 11 or so
hours of sleep. Dizziness and
some blurred vision, too, and
a general feeling of being
sick, although I haven't had
any fevers or irritations.
I've done some research on
altitude sickness and hypoxia,
and I was wondering if it was
a medical possibility to have
delayed or extended signs and
symptoms of Altitude Sickness,
or am I just tired?

hypoxia = lack of oxigen for the use of the body *can be caused by choking,metabolic dysfunctions,pulmonary distresss,diseases,drowning..a nything that take away the oxigen or lack of oxigen for use.. Ulcer=slough off of the surface area of skin,epithelials,mucous layers(like in stomach ulcers) it can be caused by traumas,diseases,infections ,chemical(like acids or alkalines) and etc.. Edema=swelling due to dysbalance of oncotic and osmotic pressures in our blood vessels tht causes plasma to come out from blood vessels to tissues..causes(chronic heart failure,stting too long in the plane,kidney problems,leakage of proteins tru kidney filters,hypertensions,etc...) |

Medical Trivia?
Eight-year-old B.J. has had
asthma for 2 years since he
had acute bronchitis. He is
tested for allergies and
demonstrated marked responses
to a number of animals,
pollens and molds. B.J. also
has a history of asthma
related to exposure to very
cold weather.
Please include references.
Describe the pathophysiology
of an acute asthma attack in
B. J. following exposure to
cats.
Describe the early signs of an
acute asthma attack and relate
each of these to the changes
taking place in the lungs.
State and explain the effects
of a prolonged asthma attack.
Explain the factors
contributing to severe hypoxia
and acidosis in a prolonged
attack.
Define status asthmaticus.
Explain why B. J. is likely to
have frequent respiratory
infections.
Suggest several measures that
B. J. can take to reduce
anxiety and perhaps the risk
of an asthma attack.
Explain why a beta2-adrenergic
agent is helpful in treating
asthma and how it is usually
administered.

Quite a lot of questions but anyway, I will try to short answers but maybe not in details. I attached good sources as your references. >>Following exposure to cats, fur particles could be inhaled and serve as stimulant or allergen which would stimulate an antigen-antibody reaction. IgE in particular will be stimulated and will result to release of histamines causing constriction of airway smooth muscles,inflammation of the bronchi and contraction of the bronchial smooth muscle. >>Symptoms include wheezing, shortness of breath, chest tightness, and coughing which are due to narrowing of the airway. Wheezing is produced when air try to pass through the narrowed tubes filled with mucus. >> the mucus-producing cells within the airway increase their output and mucus plugs the airway. The combination of airway narrowing, mucus plugging, and airway inflammation can block portions of the airway entirely. >>Air becomes trapped in the alveoli (air sacs at the end of the bronchioles). This trapped air cannot provide for the proper exchange of oxygen and carbon dioxide. Trapped air leads to hypoxia (low oxygen content) in the body. When oxygen can no longer be provided, carbon dioxide can no longer be eliminated, it will leads to acidosis ) (from carbonic acid). >>Statue Asthmaticus is a severe asthmatic attack which does not respond to standard treatments. >> Take away all allergens and possible stimulants. >>beta2-adrenergic agents causes smooth muscle relaxation resulting in dilation of bronchial passages.Administered intravenous infusion,subcutaneous injection,nebulization or orally. |
