A blood pressure meter, or sphygmomanometer, comprises an inflatable cuff and a gauge to measure pressure.

The human heart is a powerful muscle; given the right circumstances, it has the capacity to squirt blood up to 30 feet. Of course, the distance that blood could squirt depends on several factors: blood pressure -- which would depend on the heart rate -- the size of the cut vessel and the size of the cut itself.

Blood pressure

The heart pumps blood from the left ventricle, forcing it through the arterial vessels and creating pressure in the arteries. The blood moves in waves through these vessels following each beat of the heart, creating the effect of "spurting" of blood from an arterial wound.

Blood pressure depends on the heart rate, how much blood is being pumped and with what force, and the size of the artery. It is calculated that blood travels through the aorta at about 30 centimeters per second.

Blood pressure varies according to factors such as diet, general health, body temperature, an individual's emotional state, or whether they are on medication.

So, how far can blood travel?

Forensic pathologists consider all these contributing factors at murder scenes and tend to conclude that blood typically travels relatively short distances, maybe six feet at most.

Nonetheless, if optimum conditions exist to maximize blood pressure, and if the cut is small, and if the victim is upright, and preferably running at the time -- 30 feet might be possible.

Scientists believe that about 100ml of blood travels through the heart at each beat, at an average, healthy resting rate of 65 beats a minute. With a completely severed artery, an individual would maintain blood pressure for about 30 seconds and the blood wouldn't spurt much higher than his head. If the artery experiences a much smaller cut, on the other hand, it will take longer to bleed out and the blood, maintaining its pressure, will squirt farther.
