Pronunciation follows convention outside the medical field, in which acronyms are generally pronounced as if they were a word (JAMA, SIDS), initialisms are generally pronounced as individual letters (DNA, SSRI), and abbreviations generally use the expansion (soln. = "solution", sup. = "superior").
The main discussion of these abbreviations in the context of drug prescriptions and other medical prescriptions is at List of abbreviations used in medical prescriptions. Some of these abbreviations are best not used, as marked and explained here.
In biology and medicine, gravidity and parity are the number of times a female has been pregnant (gravidity) and carried the pregnancies to a viable gestational age (parity). [1] These two terms are usually coupled, sometimes with additional terms, to indicate more details of the female's obstetric history. [ 2 ]
Postpartum bleeding or postpartum hemorrhage (PPH) is often defined as the loss of more than 500 ml or 1,000 ml of blood following childbirth. [2] Some have added the requirement that there also be signs or symptoms of low blood volume for the condition to exist. [6]

[41] However, when combined with an additional underlying hypercoagulable states, the risk of thrombosis or embolism may become substantial.
