Why is bedrest and oxygen prescribed with cardiac patients?

NEED ANSWER SOON, maybe from a medical professional or nursing student

Bedrest decreases movement which in turn helps keep oxygen levels up without strain. The heart pumps oxygenated blood throughout the body. When the body is in motion, especialy more vigorous motion, the blood demand goes up, therefore forcing the heart to work harder. That is why bedrest is important. Oxygen is prescribed for the same reason, if the patient is mobile there is a supply of oxygen readily availiable to aid in easy oxygenation and flow of the blood from the heart out to the body.

Bedrest is generally only required when the patient cannot tolerate exercise for even brief periods, Oxygen, on the other hand, is prescribed for nearly all hospitalized cardiac patients, especially those who have had a heart attack or who may have damage to the heart muscle from other causes. Increased oxygen decreases the demand on the heart muscle, and increases the supply of available oxygen to the rest of the body.

I am neither a doctor or nurse but I am a person who went thru this personally. Bedrest and oxygen is something extremely vital for a person who either suffered a full blown heart attack or someone who almost had one. Depending on the person's age and health to begin with, prior to the cardiac incident determines what their body needs the most. Activity levels are decreased emmensely after having a heart attack and oxygen is badly needed in the blood stream too. Cardiac patients are generally depleted in oxygen and so they need to have it for a period of time after their heart attack experience. Some may require oxygen for a brief period of a few days to a few weeks, while others could have it for a few months, a few years or the rest of their lives. It all depends on their bodies needs and their over all health prior to their cardiac problems.

Good luck and I hope you or your loved one feels better soon!
