What cardiorespiratory diseases are caused or influenced by the environment?

What cardiorespiratory diseases are caused or influenced by the environment?

Nature vs nurture: I'll focus on lungs. Cancer can be due to tobacco exposure., even 2nd hand Asbestos too. Emphysema can also be due to tobacco. Asthma exacerbation can be due to air borne allergens especially pollen. Smog doesn't help. Influenza outbreaks can be thought of as a result of close quarters, certainly exposure to ill. I'm sure my colleagues will come up w/more. ...Read more

Why is cardiorespiratory fitness important?

Why is cardiorespiratory fitness important?

So many benefits: It helps optimize the function of your heart, lungs and vascular system. These are pretty important organ systems. Your body is an "organic" machine and exercise really helps keep it "running" smooth. This "efficiency" from exercise helps minimize risk of certain disease, like heart disease, stroke, peripheral vascular disease, just to name a few. ...Read more

How is cardiorespiratory fitness measured well?

How is cardiorespiratory fitness measured well?

V02 Max: "...Vo2 max. Or maximum oxygen uptake, is considered the gold standard of cardiovascular, pulmonary, and muscle cell fitness. It is usually standardized per body weight and expressed in milliliters of oxygen per kilogram of body weight per minute, and is the maximum amount of oxygen your body (basically your muscles) can utilize." http://www.Cptips.Com/exphys.Htm. ...Read more

Anyone know what is a test of cardiorespiratory fitness?

Anyone know what is a test of cardiorespiratory fitness?

MVO2max: In liters/minute is probably the best, although it requires "maximal exertion" which can be risky in populations at risk for heart disease. Cycling, walking, running, treadmill, stepping or so-called "sub-maximal protocols" are often used in that they don't require all-out effort to estimate fitness levels. ...Read more

What is the difference between cardiac arrest and cardiorespiratory arrest?

What is the difference between cardiac arrest and cardiorespiratory arrest?

Specificity...: Cardiac arrest means the heart has stopped beating whereas cardiopulmonary arrest means the heart has stopped beating and the person is not breathing. The latter is more specific but if the heart has stopped, the person will not be breathing. It is possible to have a respiratory arrest and the heart is still beating but if the heart stops, breathing stops, too. ...Read more

Can being bedridden for several months lead to total cardio respiratory failure and destruction of major organs? I know it always causes DVT and PE.

Can being bedridden for several months lead to total cardio respiratory failure and destruction of major organs? I know it always causes DVT and PE.

Saddle embolism/pe: prolonged immobility can result in deep venous thrombosis and pulmonary embolism as you mentioned, if the pulmonary embolism is large enough it can cause what is known as a saddle embolus which can obstruct the main pulmonary artery and can result in cardiac arrest ...Read more
