There are several things that can cause this. Hypovolemic shock comes to mind. This means you may have too little blood flowing in your body. This, by its self, will cause your blood pressure to fall. When your body recognizes that the blood pressure is too low (because your tissues will not be being perfused adequately), your heart rate will increase to attempt to compensate for the low blood pressure.
What else can I help you with?
What two things help the blood in veins return to the heart?
The blood in veins is at a lower pressure than it is in the arteries. The lower pressure makes for challenges getting that blood back to the heart. As there is less force (pressure) in the veins, blood would pool in the lower parts of the body if there were not mechanisms to prevent that. There are three different things that help blood get back to the heart. The three mechanisms are: venous valves, muscular pumps, and the respiratory pump.
What is the range for high blood pressure?
A healthy blood pressure range would be 120/80. Often if your blood pressure is higher than this you will be told you have high blood pressure and anything lower would be low blood pressure. If your blood pressure is over 140 then you should take steps to reduce this.
What system helps to slow heart the rate lower blood pressure and slow down the functions of the body?
It would be the cardiovascular system.
Would blood thinners and blood pressure medication harm a healthy heart?
Blood thinners are usually taken to prevent blood clots, they would not harm a healthy heart although they would increase the risk of bleeding in case of accidents or injuries.Different blood pressure medications lower blood pressure by acting on different receptors. Without going into too much detail, they would not harm a healthy heart, unless taken in unusually high doses.Both these medications can be taken with a healthy heart since the conditions they are prescribed for may not be heart related.
How would your blood pressure be affected if a human had a two chamber heart?
the four chambers are there to reduce blood pressure in the heart but when it is a two chambers heart the blood pressure is expected to be high because the heart will be given extra work to do.
Will diazepam lower your blood pressure?
Yes and no. Diazepam will lower your blood pressure while it is in your system, but not significantly or anything. It isn't a drug that would ever be prescribed to lower blood pressure and is not effective in that regard.
Blood pressure readings 117 over 76 with pusle 50 would you be concerned?
People who are athletic may have a lower pulse (exercise strengthens the heart, and ther heart becomes more efficient at pumping blood). 117/56: this blood pressure is normal. A pulse of 50 may be normal, but you have to look at the bigger picture: * is the person symptomatic (such as dizzy, nauseated, sweaty) * is the pulse regular or irregular * is the person on any medications that would cause a lower heart rate
Does blood pressure increase when the heart relaxes?
Nope. The blood pressure actually decreases when your heart relaxes. Although the heart relaxes, it is still in pressure or else your blood would stop flowing which to some people is a bad thing.
What is the systolic and diastolic?
Systole is the top number of a blood pressure reading. It is the heart contracting forcing blood out. Indicated by the first heart sound. Diastole is the bottom number of a blood pressure reading. It is the heart relaxing bringing blood back in.
What would happen to your blood pressure if your blood vessels became clogged?
your blood pressure would go up and your heart would beat very fast and then you would have a heart attack and either die or go to the ER almost dead or dieing. :)
What would happen if the heart did not have any valves?
The valves have to open to let blood flow into a chamber, and close before the blood flows back. If the valves do not open and close precisely on schedule, or if they fail to open or close completely, the blood will not flow efficiently. This can cause fluctuations in blood pressure, lack of flow to organs, or damage to the muscles of the heart. For example, if the aortic valve between the heart and the aorta does not close after the left ventricle contracts, there will be back pressure into the ventricle, less blood pumped out of the heart, and lower pressure in the arteries.
How do blood pressure in arteries and veins differ?
Less. The resistance of capillaries causes blood pressure to drop drastically. Also, veins lack the thick muscle surrounding that reflexively maintains blood pressure when the heart relaxes. Veins actually rely on the contraction of the skeletal muscles to maintain circulation. The larger veins also have valves in them to prevent reverse blood flow. To give you an idea, pressure in the arteries typically varies between 60 and 115 mmHg, depending on whether the heart is contracted or relaxed, whereas in a vein the pressure would be around 5-10 mmHg.
