You are enjoying your vacation on the coast and decided to go snorkeling. Your tidal volume is 460 mL and breathing rate is 14 b
reaths/min. Conducting zone of your respiratory system can hold 210 mL of air. Your snorkel gear holds 150 mL of air. What is amount of fresh air you can breathe in and out every minute (aka, alveolar ventilation) BEFORE you put the snorkel gear on
It is required to find the minute ventilation which is equal to the product of rate of breathing and the total amount of gas being inhaled or exhaled per breathe. Let this minute ventilation be denoted by ""
Thus,
where TD is the tidal volume and Br is the rate of breathing
Substituting the given values we get
We will now reduce the air held in the conducting zone of respiratory system
Air held per breathe
Total Air held
Amount of fresh air one can breathe in and out every minute
Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Every earthquake is recorded on numerous seismographs located in different directions.
