Postpartum haemorrhage is defined as the excessive loss of blood that is 500-1000 ml. Normal process after the delivery includes the contraction of uterine muscles which helps to compress the bleeding vessels where placenta was attached. But when uterine muscles fail to contract strongly it lead to haemorrhage. This excessive blood loss might result in shock and death if not treated. Estimation of blood loss and measurement of blood pressure/pulse rate can help in the diagnosis of haemorrhage.
