Because the lower chambers (the ventricles) cannot fill with the correct amount of blood, less than normal amounts of blood reach the lungs and the rest of the body. This condition is very serious and can be fatal if not treated.
It's Not Necessary Something You "get" as More it Is Something That Happens To You. Cardiac Arrest Is What's Known As A Heart Attack And Can Happen From Clogged Arteries, Overactive Heart Beating Causing Wear-Down, And High Blood Pressure. There Are more ways to get cardiac arrest too.
Cardiac arrythmias.. Sometimes life threatening cardiac arrythmias. Inneficient cardiac out put and death.
You would get a heart attack otherwise known as a cardiac arrest.
During the Valsalva maneuver, intrapulmonary pressure increases due to compressing the air inside the lungs while intrapleural pressure also increases due to the forced expiration against a closed glottis. This can lead to a decrease in venous return to the heart and a decrease in cardiac output.
When gas hydrates are brought to the surface, they lose stability due to the change in pressure and temperature. As a result, the hydrates dissociate into gas and water, releasing the trapped gas. This release of gas can cause pressure build-up and potentially lead to explosions or other hazards.
cardiac arrest
It can cause heart irregularites, or even trigger cardiac arrest.
This happens at the Sun's center, where both the temperature and the pressure are greatest.This happens at the Sun's center, where both the temperature and the pressure are greatest.This happens at the Sun's center, where both the temperature and the pressure are greatest.This happens at the Sun's center, where both the temperature and the pressure are greatest.
The pressure will increase.
decreases
nothing happens.
