Hypoxia and Medicine

What is hyperoxic anoxia? Is it poisoning by toxins in oxygen? A medical dictionary definition would be appreciated if you can find one. I need to keep this "professional".

Why does anoxia cause cell death? I understand that most of a cell's chemical processes would stop because of a lack of energy, but what causes the cell to "die"? Why doesn't it just drop what it's doing (so to speak) and wait until it has an oxygen supply again? Why does the inability of a cell to carry out respiration cause it to die? Ashkon, you mentioned some required processes that would cause death if not negatively regulated. Anyone have any idea what sorts of processes those would be?

Anoxia and Brain damage? Why are neurons and other brain cells more vulnerable than other cells to oxygen depravation? Is it becaue they are more sensitive to changes in pH that result from anoxia? If so , why?

what causes anoxia? listed on death certificate as cause of death, but also stated died of natural causes. Is this unusual? I am not talking about anorexia which is starvation.

Brain anoxia and reperfusion iojury? I have come to know the following happens during a cardiac arrest. 1) Anoxia during cardiac causes exitotoxosis due to the ischeamic cascase. This is evident here... http://en.wikipedia.org/wiki/Ischemic_cascade So why are there no covulsion during a cardiac arrest no matter how long it lasts? 2) Reperfusion injury where reoxygenation starts using the built up glutamate store in the brain to over-exite the brain. This is evident here... http://en.wikipedia.org/wiki/Reperfusion_injury But I do not hear much about patients convulsing then. They may be having a very long form of atonic convulsions during cardiac arrest or reperfusion injury, but how would we know? http://en.wikipedia.org/wiki/Atonic_seizure Do you know if they do, and if they do not why, because reading all the stuff it says about ishemic cascades, it does not add up with what really happens to cardiac arrest patients. What is it that I am missing here, explain in detial? CREED

My baby died 7 month gestation of anoxia intrauterine, can u help us understan what could have went wrong help anoxia intrauterine means not having enough oxygen but i cannot understand, everything was going fine all of a sudden the baby stopped moving inside the womb. This has us very stressed and frustrated, we were waiting for this baby for eight years and now everything has gone down hill. If there is someone that can help us please tell us something, because even the umbilical cord was no wrapped around the babies neck, the baby was in perfect shape already. If there is a doctor out there or someone with some knowledge please help us.

How do oxygen and carbon dioxide change with depth? What processes affect the concentration of these gases at different depths and what happens in areas with anoxia?

how do you acheive cerebral anoxia?

is there any treatment for Anoxia? Is brain damage reversible?

Can heart conditions and/or diseases be passed on genetically? I had congestive heart failure. The reason has never been determined. My cardiologist theorizes that I may have gotten it through genetics or a virus before birth. Now I have been diagnosed with anoxia cardiomyopathy and hypertension. Will these conditions be passed on to my kids (if I have them)? Serious responses only please. I am being serious. There are no other cases of heart disease in my family. I'm the only person that has ever had these conditions.

what food items can lower high cholesterol level,and what are the foods allowed/not allowed? my boss had hyperlipidemia,had heart attack,went comatose for 18 days.now he had memory loss and brain anoxia, and at times has to take .25 mg clonazepam for panic disorder.

did you know that you could die from masturbating? Q. What is auto-erotic asphyxiation? A. Auto-erotic asphyxiation is the Induction of cerebral anoxia -- a deficiency of oxygen in the brain -- through self-applied suffocation methods while masturbating. It is estimated that between 500 and 1000 deaths occur annually in the United States from this dangerous type of masturbation. Most commonly performed by young adult males, it almost always remains a secret until they die accidentally. The interference of blood supply to the brain brought on by auto-erotic asphyxiation can intensify sensations. The lack of blood, therefore oxygen to the brain can produce giddiness, exhilaration or a self-induced "high". It's also believed the self-endangerment inherent in the technique enhances the person's sexual gratification. This technique often involves using a rope, belt or another device to cause the asphyxiation. Of course, this same self-endangerment that may provide a thrill to the person carrying out auto-erotic asphyxiation also weakens one's self-control and judgment possibly resulting in accidental death.

Why has humanity never studied the real time fetal response to uterine orgasm. Jeff Schofield? Let the fetus have its say regarding sex during pregnancy and in particular the fetal response to uterine orgasm. The contractions of delivery during birth cut off the blood supply and would suffocate the fetus if not spaced out. Uterine orgasm during pregnancy can last up to 30 minutes. The same physiology must exist as during birth with the cappillaries at the uterine-placental junction being clamped shut by the contracting uterine muscles. It is obvious the fetus survives,but what if repeated breath holding contests inutero lead to asthma etc. What if the reduced flow of cord blood leads to toxemia and anoxia as in a drowning victim? 5000 fetuses are aborted daily in America. If we can justify intruding on the fetal space with abortion, I pray the time has come that some brave researchers will use the high-tech fetal monitoring tests to let the fetus have its say. What are we so terrified of learning? Sex during pregnancy is such a common human experience, fear not I AM

which is a greek word that means without a pulse? a. asphyxia b. anoxic c.anoxia

Question About Fish In A Pond? Which of the following conditions will most likely result in anoxia effect and may kill the largest number of fish in a pond? a) a cold day during an algal bloom b) a hot day during an algal bloom c) a cold night during an algal bloom d) a hot night during an algal bloom e) a cold day

Question about Rotenone? Rotenone, a natural poisonous metabolite found in derris root from tropical rain forests, is used as an insecticide (insect killer) and ichthyocide (fish killer). Its mode of action is through binding to an Electron Transport Chain molecule located within the inner mitochondrial membrane. You would correctly predict that rotenone would _________ nerve transmission (action potentials) in neurons of herbivorous insects by __________. a) decrease ; binding with post synaptic acetylcholine receptors b) increase ; increasing synthesis and release of acetylcholine from anoxia c) decrease ; decreasing production of ATP to drive the NA+-K+pump d) increase ; mimicking acetylcholine Please include your reasoning behind your answer. Thank you.

Help Im sooo confused!!!!!!!!!!!!!? Hi recently my daughter was born sleeping due to Anoxia-lack of oxygen through the cord. I need help Im wondering if this is likely with other pregnancies to come??? Im so worried of losing another precious angel!!!!!!!

More callenge(Q2).......why not?? A recent study says:Human beings need oxygen and air pressuer in order to live.Breathing is made possible by the oxygen in the atmosphere reaching the air sacs in our lungs.As elevation rises,however,atmospheric pressuer goes down as the atmosphere becomes thinner.Therefore the amount of oxygen entering the blood stream declines and it becomes harder to breath.As the air sacs grow narrow and contract,we feel as if we cannot breath. Someone at 5.000-7.500meters above sea-level may faint because of breathing difficulties.That explains the presence of oxygen equipmentin planes and the special system that regulate the air pressuer when planes fly at 9.000-10.000.Anoxia occurs when the oxygen fails to reach the tissues.This oxygen deficiency occurs at height of 3.000-4.500meters. IN THE COMPARISON MADE IN THE VERSE BELOW,this physical truth,the changes that take place in chest with increasing the height,is indicated in these terms(IN THE Holy QURAN centuries ago) ALLAh says"WHEN ALLAH DESIRES TO GUIDE SOMEONE,HE EXPAND HIS BREAST TO ISLAM,WHEN HE DESIRES TO MISGUIDE SOMEONE,HE MAKES HIS BREAST NARROW AND CONSTRICTED AS IF HE WERE CLIMBING UP INTO THE SKY..6:125)" MY Q. IS:if u deny that this Quran is from ALLAH can u make a chapter like it with such a scientific miracle? ALLAH says"AND IF YOU ARE IN DOUBT CONCERNING THAT WHICH WE HAVE SENT DOWN TO OUR SLAVE,THEN PRODUCE A CHAPTER LIKE IT AND CALL YOUR WITNESS BESIDE ALLAH,IF YOU TRUTHFUL"quran. N.B:When ALLAH says about Himself WE,HE means majesty not plural as ALLAH is ONE.

for a black / doom / death metal band , wat do you think as a better name and why? 1. crimson haze 2. guards of darkness 3. anoxia 4. rise of choas 5. frequent 6 6. demon's shrine

hematology testing? it was suggested to my son that he have neurtoxicology, hypoxia/anoxia & neuroimmunology screenings done, also to look for toxins/heavy metals, lead etc...what tests exactly do we request?? it seems that we can't get an answer nor much help from our pmd nor from the neuro dr. that he is seeing. he has been to brain matters in Colorado & had a pet scan done 1 yr ago & they suggested that we follow up at home, but again, we seem to be hitting a brick wall, all they want to do is to keep trying him on meds for bipolar which do not help him at all, the side effects are not worth keeping him on the meds.. He strongly feels that ther may be something else going on and possibly the testing may help us or let us know that there is nothing else. If possible, i would like to know exactly how these test are performed, the more info we have the better educated we are as to what to expect. i would greatly appreciate any help whatso ever.. we are just trying to get him well..thanks sooo much..

In the near future is it POSSIBLE Oceans Currents will stop and turn Seas into Stagnant SOUP? Honestly, NOT trying to be hyping on Gloom & Doom...but I just saw this on Nat. Geo. that during Proterozoic Period, warmer temperatures widely attributed to high levels of atmospheric greenhouse gases such as carbon dioxide causing the 'Breistroffer' event, stopping our ocean currants causing anoxia, stagnation of our oceans, turning it into a virtual poison. Since our temperatures are rising at alarming rates and our sea surface temperatures increase 3–5 °C warmer than it is today(which is what it was when it occurred before), does anyone feel this event will occur again? Are we setting ourselves up? Not if but when? Your constructive ideas/thoughts are appreciated. http://arstechnica.com/journals/science.ars/2008/05/01/increased-deoxygenation-of-the-oceans http://en.wikipedia.org/wiki/Anoxic_event
