Those amounts are equivalent to about 2 cups of air in a single breath. Since the average person at rest breathes about 12 times per minute, with a tidal volume of a half liter per breath, that equates to a rate of about 6 ...
Blood circulates across our bodies, supplying important nutrients and oxygen to the body's cells. It also transfers mitochondrial waste products away from the cells in question. Blood is the only thing that can replace it thus it is impossible to create or produce. Patients in need of a ...
aSome salt solution with a concentration of 70% is mixed up with some salt solution with a concentration of 58%.And the new solution had a concentration of 62%.If we take 15 more liters of each solution,the mixture we get will have a concentration of 62.25%.How many liters of solutio...
The ratio of breath alcohol concentration to blood alcohol content is 2,100:1. This means that 2,100 milliliters (ml) of alveolar air will contain the same amount of alcohol as 1 ml of blood. For many years, the legal standard for drunkenness across the United States was 0.10, but ...
A normal balloon at an amusement park might be 30 centimeters (about 1 foot) in diameter. To determine how many liters of helium a sphere can hold, the equation is 4/3 x pi x r x r x r. The radius of a 30-centimeter-diameter balloon is 15 centimeters, so: 4/3 x pi x 15 ...

It's not really the number of seconds that's key, however, so much as the amount of air you're taking in during that breath. Helpfully, the ideal amount is also easy to remember: It's 5.5 liters. McKeown feels that timing your breaths is a distraction from making sure each one is...
**Tidal volume (VT)** is the amount of gas expired in each breath, usually about half a liter. **Dead space volume (VD)** is the sum of the "anatomic" dead space, which is wasted airway space, and the "physiologic" dead space, resulting from alveoli that are getting...
Incentive spirometer normal range A normal range on the incentive spirometer depends on your age, height, and sex. For example, for a 40-year-old woman who is 5 feet 4 inches tall, the incentive spirometer goal by age would be 2,300 mL. For a 60-year-old man who is 6 feet tall,...
Blood clotting is an important part of hemostasis, the balance of anti-coagulation and pro-coagulation mechanisms that preserves normal blood flow throughout the body. In healthy conditions, blood clots, which includes venous and arterial clots, form to prevent blood loss after an injury to a blo...
