For clinical purposes, the terms ‘haematocrit’ and ‘PCV’ are used interchangeably. The relationship between haematocrit and haemoglobin concentration in a given sample is influenced by the size and haemoglobin content of the red cells. A useful conversion factor is that haematocrit (%) is approximately equal to three times the haemoglobin concentration. 1. 3 Clinically important anaemia It is relatively simple to define a patient as being anaemic by comparing his or her haemoglobin concentration with a normal or reference range.
Hormonal responses Many of the same hormonal responses to acute blood loss also occur in chronic blood loss, although the degree of compensation required is considerably less. Thus, red cell production is stimulated by erythropoietin, provided there is sufficient iron available for haemoglobin synthesis, and blood volume is maintained by the action of vasopressin and aldosterone. Clinical features of chronic blood loss Provided that the patient’s compensatory mechanisms are effective, chronic anaemia may cause few clinical symptoms or signs until a relatively low haemoglobin concentration is reached.
