"Anemia can be defined as a reduced absolute number of circulating red blood cells. In practice a low hemoglobin concentration or a low hematocrit is most widely accepted definition for anaemia.
Red blood cells are the cells that carry oxygen around our body. Red blood cells also known as erythrocytes arise from myeloid progenitor cells in the bone marrow. Erythropoesis is the process of erythrocyte production. Myeloid progenitor cells become reticulocytes. This path is stimulated by hormones including erythropoietin. The reticulocyte enter blood stream 3 days later and matures to become a RBC in circulation. The mature RBC circulates for around 120 days, after which time it is removed from the circulation by the reticuloendothelial system.
When performing a FBC or CBC, looking at Hb is the first step in diagnosing anaemia. One way to categorise anaemia is be looking at the mean corpuscular volume. Mean corpuscular volume (MCV) is the average size of a persons RBCs Therefore one way to categorize anaemia is using the MCV. You can have microcytic, Normocytic and marcocytic anaemia. Another way to classify anaemia is by looking at the pathophysiology."

I'm study for my Adult Geriatric Np boards and this video has clarified everything I need to know. Thank you for your wisdom.
Every letter said in this video is very important and must be memorized
Thank you very much you are a life saver .
Appreciate this very clear covering video on anemia. You've helped me so much.
How did you know that I needed this video? I’m currently studying for my FNP boards and this is the topic I’m working on!! Woot!
Are you an FNP yet? It's been two years. I have a case study for you:
A 40 yr old female presents with extreme fatigue, intermittent SoB and singleton pregnancy at 17 weeks gestation. PMH of Hashimoto thyroiditis, iron deficiency anemia.
Vitals: 101/60 63 98.0 21 res.
This is amazing work!
Can you please upload a picture/screenshot of the whole final plate at the end of the video? Would be very useful to have on my smartphone for quick use.
Thank you Armando and keep up the good work! I am happy to just have subscribed to your channel!

The best definition I've come across is that anaemia is where there is a clinically significant reduced oxygen carrying capacity of the blood. I think that's the best briar definition
I love this and ninja nerd’s lectures... both are informative and entertaining... i’m reviewing for my exams and i graduated 10+ years ago 😅
