well it depends what was happening to cause the loss of blood if someone was slashed by a bear their heart rate would be very high if someone was just donating alot of blood it would be slow, in general losing blood = slow heart rate, basically like being sufficated because that's basically whats happening
Blood pressure would decrease
Blood pressure is the blood flow when the heart is pumping (top number) and when the heart is resting (bottom number). The body is a closed system and requires enough blood pressure to pump the blood throughout the body. A typically healthy blood pressure would be 120mmHg/70mmHg. Atmospheric pressure is the weight of the atmosphere at a specific location and altitude. At sea level, atmospheric pressure is 760mmHg. So actually, atmospheric pressure is much greater than blood pressure. Most people never have to worry about atmospheric pressure affecting blood pressure. However, deep sea divers experience an increase in blood pressure while diving, and astronauts experience a decrease in blood pressure when in space.
Serious dehydration is a form of hypovolaemic shock and would lower BP.
Yes, blood pressure is a measure of the pressure exerted on your arterial walls as the heart pumps blood throughout the body (systolic) over the pressure when your heart is relaxed (diastolic).
if your taking blood pressure in the anticubital area (crease of the elbow) then you would palpate the brachial artery.
