Why do peeps who are anemic not exhibit an increase in resp. rate or tidal vol. even though their blood is not

because the regulatory mechanisms that control rr and tv are mainly controlled by the autonomic nervous system ie hormonal control, low o2 conc does not affect these as the there are no feedback mechanisms from the tissues that need the o2, the systems, in other words , are not intrinsically linked

Red blood cell (RBC) count. Red blood cells carry oxygen from the lungs to the rest of the body. They also carry carbon dioxide back to the lungs so it can be exhaled. If the RBC count is low (anemia), the body may not be getting the oxygen it needs. If the count is too high (a condition called polycythemia vera), there is a risk that the red blood cells will clump together and block tiny blood vessels (capillaries).

Wow, some disjointed questions there.\n\nTo increase red cell production, have a healthy diet and make sure you get enough iron.  Iron is required for hemoglobin production, and hemoglobin is the business part of the red blood cell.\n\nYour height shouldn't make any difference with your heart function.  Your weight, however, might.  Eat a healthy diet, and exercise, and your heart should do just fine.

Though they may call that test that, they are NOT checking for iron.\n\nThe test is technically called a 'hematocrit' and is intended to test the amount of red blood cells in your blood.  This test is required by law, though the actual form of the test may vary depending on where you are going.  For accurate results like you're desribing, they probably centrifuged your blood and measured the volume directly.\n\nThere are lots of things which can affect the amount of red blood cells you have kicking around, and one of the more common problems is an iron deficiency.  This is probably why it is often referred to as 'checking your iron'.  Other things include illness, bleeding, and sometimes just a natural tendancy in some people to have less.\n\nNow... I can tell what you're thinking.  "If I'm giving PLATELETS, what difference does it make if I don't have enough red blood cells.  I get everything but the platelets back, right?"  And this is completely true.  Usually.  The wrinkle is that the apheresis machine which separates out your platelets usually has about a half a litre of your blood in it while it's operating.  If something should go wrong, either in the machine or if you have a reaction, they may have to just pull the needle from your arm and you'll be out that much blood.  So they want to make sure you have enough to lose!\n\nAnd just as there are things that lower the amount of red blood cells you have circulating, there are also things that raise it.  Making sure you're eating enough iron is a good one... but be careful with this.  Iron in large amounts can be toxic, and vitamin C eaten at the same time can interfere with your digestion of iron.  Donating whole blood regularly can prompt your system to overproduce red blood cells a little bit to compensate.  Likewise with spending time at high altitudes.  Female people may just want to schedule such appointments before instead of after their 'time of the month'.\n\nHope all that helps!  Don't get discouraged... lots of people end up with a low hematocrit from time to time.  Donating is a GREAT thing!

Forgive me for pointing this out, but survival is possible.\n\nOhter things can be used to maintain circulating volume: crystalloids (like saline) and albumin are the main ones.  Certainly, if you don't get transfused when you need it, you will have some real trouble with anemia, and with oxygen transport--but certain religioius groups, notably the Jehovah's Witnesses, refuse blood transfusions, no matter what.  They often endure more prolonged recovery because of that choice, and certainly many of them die when they would probably have survived with the transfusion, but the transfusion refusal is not a guarantee of death, even in extremely grim situations.\n\nIn longer term situations, the recovery can be accelerated by using erythropoetin or an erythropoetin analog to accelerate production of red cells; this is slower than transfusion, but it has rescued a lot of people who refused transfusions.

This is common in vegetarians... are you?  It could result in megaloblastic or pernicious anemia & neurological degeneration of neurons.  You probably have fewer than normal red blood cells, thus a reduced oxygen-carrying capacity.  You need to be taking supplements.

if it stays low from what I understand from family members being anemic your body could go into shock and that can bring on other illnesses.  being anemic is not a good thing because your body needs the iron to fight off infections and viruses.  That is why people who are anemic if they do not take care of themselves they are always cold and they are always sick with the flue or a cough.

Itching (pruritis) is not a symptom of anemia.  You may have simple dry skin.

Low levels could indicate anemia.\nhttp://www.lymphomation.org/CBC-blood-counts.htm\n\nHCT - Hematocrit  (he-MAH-to-crit)\nRef.  Range 38.5 - 49.0%\nPercent of  your blood that is occupied by red blood cells. Good indicator of anemia.\n\nHGB - Hemoglobin  (HE-muh-glow-bin)\nRef.  Range 13.2 - 16.9\nHemoglobin is a protein used by red blood cells to distribute oxygen to other tissues and cells in the body.  Low levels indicate anemia.\n\nRBC - Red blood cells (erythrocytes - eh-REETH-ro-site)\nRef.  Range 4.20 - 5.70\nCells that deliver oxygen throughout the body and make blood look red. A low RBC can indicate anemia, which can lead to fatigue.\n\nRDW - Red Cell Distribution Width\nRef.  Range 11.0 - 15.0\nMeasures the range of sizes of red blood cells in a blood sample. RDW results are often used together with MCV results to determine possible cause of anemia when anemia is indicated by other test results.\n\nMPV - Mean Platelet Volume\nRef.  Range 7.5 - 11.5\nMeasures the average volume (size) of your platelets. Higher-than-normal MPV is associated with an increased risk of heart attacks and stroke.\n\n"Anemia"\nhttp://kidshealth.org/parent/medical/heart/anemia.html\n\n"Anemia, one of the more common blood disorders, occurs when the number of healthy red blood cells decreases in the body."

The blood treats the problem..eg anaemia is lack of quality red bloods cells-> -> blood given, now patient has good quality blood cells, for a short while anyway...;

you may be anemic. my ma bruises easy and she is. just take more iron tablets

hypoxic condition stimulates our kidneys to produce a hormone called ERYTHROPOETIN which stimulates the bone marrow to produce more erythrocytes thus compensating for the stress

That is weird, my friend and I were discussing that yesterday. She had been to the doc and he said that the blood bank loves her blood, she is 0 neg. too. She told me that anyone can get her blood, but she could only have 0 neg. herself. I never knew that! I have no idea what type I am, but I will find out now. Thanks for reminding me to do that!

there is no direct relationship with the two, however is does not mean that both cannot be elevated, high blood pressure is caused by many different things , and something the cause high blood pressure may sometimes also be equated to having cause a higher hemo count. but  the two are not directly proportionate

You need to take a multivitamin with100% Iron because I am anemic with the same problems, buy a big bottle and start off taking 2 aday to build up.

Have you been tested to see if you are anemic.  I am anemic and when my hemoglobin drops low sometimes I get dark cicles under my eyes that won't go away until my iron levels rise.  Just something to check into

maybe you a. dont get enough sleep b. are anemic c. have a thyroid problem or d. suffer from depression e. many other reasons
