The idea of finding and raising the Titanic was thought of very soon after the sinking of the vessel. However, the first successful attempt at locating the Titanic Wreck was in 1985 by a French and American expedition led by Jean-Louis Michel and Dr. Robert Ballard.
The higher the pressure, the harder the heart has to pump. Normal adult blood pressure is defined as a blood pressure of 120 mm Hg1 when the heart beats (systolic) and a blood pressure of 80 mm Hg when the heart relaxes (diastolic).
Normal blood pressure range is a systolic number less than 120 and diastolic reading of less than 80. Systolic, which is the top number, measures pressure in the arteries during heart beats. Diastolic, the lower number, measures the pressure in the arteries between heartbeats.
