Nothing much. You just get tired. Sometimes it happens when you're too fat, that's why fat people sometimes walk slower and you can hear them panting. If you are very very fit, your heart goes a bit slower, so when you are running it speeds up later, giving you more energy to run. That is why all (most) runners are so skinny.

∙ 13y agowhen there is bleeding there will be low or inadequate oxygen delivered to the tissues and organs.By the negative mechanism these receptors will send the signals to the brain and thus stimulate heart to pump faster and lead to tachycardia.

∙ 9y agoYes, a loss in blood pressure can increase heart rate. Delivery of oxygen and nutrients to the tissues depends on the blood pressure and the heart rate. If the blood pressure drops, the heart rate may need to increase to deliver enough oxygen to the tissues.

Would you expect a fast or slow pulse with a sudden drop in blood pressure from loss of blood?
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
Why does blood volume loss cause tachycardia?
Because the heart itself needs a blood supply in order to function. If the heart is starved of its own blood - it will stop.
Why do patients with a heart rate greater than 160 not receive nitroglycerin for chest pain?
At this fast a rate, the heart chambers do not have adequate time to refill fully with blood. This is called fibrillation and is associated with a corresponding decrease in cardiac output and lower blood pressure. Since nitroglycerin also causes lower blood pressure by dilating or expanding the vessels, the additive effect could cause loss of consciousness.
Is Arteries and The Heart the same thing?
The artery and the heart are both part of the cardiovascular system, but they differ in meaning. Arteries carry blood away from the heart. They are thick-walled and elastic. Blood from the arteries is under high pressure since it has just come from the heart. A cut in the artery may be fatal due to blood loss. However, this thickness, elasticity, and location protect it from damage. The heart is like the central station. It is a powerful muscular organ. It is also responsible for the circulation of blood.
How does the heart compensate for changes in peripheral resistance?
Bleeding, technically known as hemorrhaging or haemorrhaging (see American and British spelling differences) is the loss of blood or blood escape from the circulatory system.[1] Bleeding can occur internally, where blood leaks from blood vessels inside the body or externally, either through a natural opening such as the vagina, mouth, nose, ear or anus, or through a break in the skin. The complete loss of blood is referred to as exsanguination,[2] and desanguination is a massive blood loss. Typically, a healthy person can endure a loss of 10-15% of the total blood volume without serious medical difficulties, and blood donation typically takes 8-10% of the donor's blood volume
What is the effect of hypovolemic shock on the blood vessels and the heart?
Blood vessels constrict to increase venous return and maintain pressure. Heart rate increases to compensate for loss of blood pressure and to maintain cardiac output.
When you cut off your finger does your blood pressure increase?
The pain and the stress from the injury can result in a temporary increase in blood pressure. But if it's not tended to immediately and the blood loss stopped, it can result in a drop in blood pressure. This drop can sometimes be severe.
Does hemorrhage increase blood pressure?
the question is not sufficiently specified to enable a good answer in a short essay. There are many kinds and degrees of "Hemorrhage" No. A hemorrhage causes a loss in blood/plasma, and that will decrease the hydrostatic pressure of the vessels --> decrease blood pressure.
Does hemorrhage increase or decrease blood pressure?
Blood has a normal viscosity dependent on adequate hydration and the absence of any illness that could affect normal electrolyte balance in the body. As blood thickens, it becomes harder for blood vessels to return the blood through the venous and arterial blood vessels. This increases the work of the heart, as a pump, to move the thickened blood to the brain and vital organs, out to the limbs, and have it return again for oxygenation and the process continues again. Various factors combine to increase heart rate and blood pressure.
How would decreasing the amount of water in the blood affect blood pressure?
Blood pressure would decrease
Why does blood pressure decrease after long term exercise?
Yes your blood pressure will decrease for a couple of different reasons: The first is that your blood vessels have dilated to provide muscles with an increase in oxygenated blood and the surface (peripheral blood vessels) will dilate to increase the rate of heat loss from the body. Over a sustained period of exercise (months) the blood vessels will become more elastic, decreasing the pressure on the vessel walls and more importantly on the left ventricle of the heart. There will be a similar decrease in your resting heart rate. Overall your cardiovascular system will become "younger".
How does head trauma cause immediate loss of consciousness?
When there's brain injury, the brain will swell, and the blood vessels will leak. which causes increase in the blood and cerebral blood flow to the brain, but as the brain is accommodated inside the skull and it can't be expanded, this will increase the pressure inside, the intracranial pressure, which will interfere with the blood flow to the brain, decreasing it and causing loss of consciousness
What does blood pressure 44 over 34 and pulse 128 mean?
Probably a large loss of blood. Not enough to keep the pressure up and the heart beats faster to try and compensate.
Can heavy blood loss cause heart damage?
Heavy blood loss can and will cause heart damage and that is not a good thing and you can die from blood loss to your hearttt...
Why is it dangerous for a person if one of his arteries is cut?
Arteries carries the high-pressure blood coming from the heart, so a cut artery will bleed a lot more than a cut vein, which carries the low pressure blood returning to the heart. Lacerating an artery can result in severe blood loss. Severe blood loss can result in damage to the brain which, depending on the location and severity of the damage, can cause loss of coordination and mobility, loss of sensation or sensory ability in part or totally, and/or loss of cognitive functions. Of you could just die.
Why risk of bleeding post operatively in extraction of hypertensive patient?
excessive vascular pressure will increase blood loss at surgical site
How the blood vessels can respond to the lack of blood?
vasoconstriction and venoconstriction (arteries and veins) renin/aldosterone secretion by kidneys (to increase blood volume by preventing water and sodium loss) blood redistributed to vital organs (brain, heart, kidney and liver) tachycardia of heart (increased heart rate
