Abnormally low hematocrit (hct) and hemoglobin (hb) levels-rationale.
Explanation:
Abnormally low hematocrit (hct) and hemoglobin (hb) levels-rationale. At low pre-operative hct and hb levels indicate the patient may require a blood transfusion before surgery.
if the hct and hb levels decrease during surgery because of blood loss, the need for a transfusion increases.
A complete blood count (CBC) or full blood count (FBC) is a hematological laboratory investigation which comprises of the following tests:
1. White blood cell count which includes both total count and differential count. It gives a pointer to the immunity level of the patient.
2. Platelet count- this shows the bleeding tendencies.
3. Packed cell volume(PCV) or hematocrit level: This shows the red blood cell fraction in the blood. If low, patient would possibly need a transfusion or would build with hematinics before the surgery.
4. Mean corpuscular volume (MCV)
5. Mean corpuscular hemoglobin(MCH)
6. Mean corpuscular hemoglobin concentration(MCHC)
6 ways of expressing standard atmospheric pressure include: millimetres (or inches) of mercury, pounds per square inch (psi), dynes per square centimetre, millibars (mb), standard atmospheres, and kilopascals.
