Respiratory History
This ancient physician is traditionally known as the father of medicine.
Who is Hippocrates?
Pressure and volume change inversely when temperature remains constant.
Who is Boyle's law?
Normal atmospheric pressure at sea level in mmHG.
What is 760 mmHg?
Fluid molecules moving in smooth, streamlined layers demonstrate this type of flow.
What is laminar flow?
Of helium, carbon dioxide, nitrous oxide, and air, this gas is the least dense.
What is helium?
This individual described oxygen as "dephlogisticated air" after discovering it in 1774.
Who is joseph Priestley?
Volume changes directly with absolute temperature when pressure is constant.
What is Charles' law?
Approximately this percentage of the Earth's atmosphere is nitrogen.
What is 78%
Flow often becomes this type when a tube branches.
What is turbulent flow?
This gas moves from an area of higher concentration to an area of lower concentration by diffusion.
What is any gas / diffusion?
He is credited with the earliest therapeutic use of oxygen.
Who is Thomas Beddoes?
The total pressure of a gas mixture equals the sum of the individual partial pressures.
What is Dalton's law?
At sea level, the approximate partial pressure of oxygen in dry atmospheric air is this value.
What is 159 mmHg?
Laminar, turbulent, and this third type are recognized flow patterns.
What is transitional flow?
This process changes a solid directly into a gas without passing through the liquid state.
What is sublimation?
This scientist developed large-scale oxygen production in 1907.
Who is Karl von Linde?
Pressure changes directly with absolute temperature when volume remains constant.
What is Gay-Lussac's law?
A mixture contains 25% oxygen at 760 mmHg. The oxygen partial pressure is this.
What is 190 mmHg?
The relationship among pressure, flow, resistance, tube length, viscosity, and radius is described by this law.
What is Poiseuille's law?
Dry ice is a classic example of a substance undergoing this process.
What is sublimation?
This Renaissance figure recognized that animals require something in the atmosphere to sustain life.
Who is Leonardo da Vinci?
This law combines pressure, volume, and temperature into one relationship.
What is the combined gas law?
According to Laplace's law, doubling surface tension while keeping radius constant does this to pressure?
What is doubles the pressure?
A stream of gas that follows nearby curved surface demonstrates this phenomenon.
What is the Coanda effect?
As the temperature of most liquids increases, this physical property decreases.
What is surface tension?
