How is PPH measured?

Several methods have been used to assess PPH, particularly after vaginal delivery, that include visual estimation, gravimetric measurement, direct measurement, photometry and other methods such as the shock index method, red blood cell counts, and hemoglobin levels.

What is considered a PPH?

Severe bleeding is called a haemorrhage. A primary postpartum haemorrhage (PPH) is when you lose a lot of blood in the first day after giving birth. After a vaginal birth this usually means you have lost at least 500 mL (half a litre) of blood and after a caesarean section at least 1000 mL (a whole litre) of blood.

How many liters of blood does a pregnant woman have?

During pregnancy, the total maternal blood volume increases about 50% to approximately 5 liters.

How do you calculate blood loss during PPH?

Record the total volume of fluid collected in the under-buttocks drape. Subtract the preplacental fluid volume from the post placenta fluid volume to more accurately determine the actual blood loss. Keep in mind that most of the fluid collected after the birth of the placenta is blood.

How much blood loss is a PPH?

Primary PPH is when you lose 500 ml (a pint) or more of blood within the first 24 hours after the birth of your baby.

What is severe PPH?

Postpartum hemorrhage (PPH) is severe vaginal bleeding after childbirth. It’s a serious condition that can lead to death. Other signs of postpartum hemorrhage are dizziness, feeling faint and blurred vision. PPH can occur after delivery or up to 12 weeks postpartum.

What are complications of PPH?

Immediate and late complications of primary postpartum hemorrhage include hypovolemic shock, cerebral anoxia, renal failure, anemia, puerperal sepsis, and Sheehan’s syndrome. The antepartum hemoglobin status and the rate of blood loss influence hemorrhage outcome.

What is the world record for the 1500m?

Olavi Salsola, Olavi Salonen and Olavi Vuorisalo ( The three Olavis) break the 1,500 m world record in 1957 in Turku, Finland. The 1500 metres or 1,500-metre run (typically pronounced ‘fifteen-hundred metres’) is the foremost middle distance track event in athletics.

The 1500 metres or 1,500-metre run (typically pronounced ‘fifteen-hundred metres’) is the foremost middle distance track event in athletics. The distance has been contested at the Summer Olympics since 1896 and the World Championships in Athletics since 1983.

How long does it take to run a 1500m?

It is equivalent to 1.5 kilometers or approximately 15⁄16 miles. The demands of the race are similar to that of the 800 metres, but with a slightly higher emphasis on aerobic endurance and a slightly lower sprint speed requirement. The 1500 metre race is predominantly aerobic, but anaerobic conditioning is also required.
