Egan's Fundamentals of Respiratory Care: Midterm Review RES1010 Flashcards

Water vaporized with medications to be inhaled

Use of various techniques and devices to establish or maintain a functional air passageway

The combination of cardiac and pulmonary systems. ie: The heart and lungs

The committee on accreditation for respiratory care. This committee accredits schools programs on respiratory care.

The national board of respiratory care. This board administers the testing to become certified and registered respiratory therapists.

The abilities to deliver oxygen to people who are having oxygen deficiencies.

Pulmonary function tests, wide range of diagnostic procedures to measure and evaluate lung functioning.

Health care discipline that specializes in the promotion of optimal cardiopulmonary function and health.

Health care professionals who are educated and trained to provide respiratory care to patients.

Apply scientific principles to prevent, identify and treat acute or chronic dysfunction of the cardiopulmonary system.

the use of mechanical devices to provide ventilator support for patients.

A private non-governing agency that establishes guidelines for the operation of hospitals and other health care facilities, conducts accreditation programs, surveys, and encourages the attainment of high standards of institutional medical care.

Specification of actions that allows respiratory care practitioners to initiate and adjust therapy independently, within guidelines previously established by the medical staff.

Solid, Liquid, and Gases. Solids have a fixed volume and shape, they have strong mutual forces between atoms. Liquids have a fixed volume but adapt to the shape of their container. Atoms have less mutual attraction to each other. Gases molecular forces are very weak. They are easily compressed and expanded. They have no fixed volume or shape.

The actual mass or content of water in a measured volume of air, usually expressed in grams per cubic meter or pounds.

band of scar tissue that binds anatomic surfaces that are normally separate from each other.

Ambient Temperature Pressure Saturated. A correction factor

Attractive forces between like molecules.

change of a state from gas to liquid. As with water vapor condensation.

the transfer of heat by the direct interaction of atoms or molecules in a hot area that contact atoms or molecules in a cooler area.

the highest temperature at which a substance can exist as a liquid, regardless of the pressure.

law stating that the total pressure exerted by a mixture of gases is equal to the sum of the pressure exerted by the individual gases if they were present alone in the container.

the difference in pressure between the two points along a tube divided by the actual flow.

use of the Bernoulli effect to draw a second fluid into a stream of flow. A vacuum effect.

the energy of motion or movement.

a fluid moving in discrete cylindrical layers or streamlines through a tube.

laws that describe the relation between temperature and the kinetics of matter changing it's state. Energy can not be created or destroyed. the conservation of energy

temperature at which the solid and liquid forms of a substance are in equilibrium.

heat transfer without direct contact.

a gas that is not fully saturated, the ratio of it's actual water vapor content to it's saturated capacity at a given temperature.

the tendency of a liquid to minimize the area of it's surface by contracting. This property causes liquids to rise in a capillary tube, effects the exchange of gases in the pulmonary alveoli, and alters the ability of various liquids to wet another surface.

measure of heat. four methods of heat transfer, conduction, convection, radiation, and evaporation.

Fluid molecules forming irregular eddy currents in a chaotic pattern.

is the change of state from liquid to gas. vaporization requires heat energy.

is the force opposing a fluids flow.

the pressure exerted by water in it's gaseous state.

a phenomenon in which a liquid in a small tube moves upward against gravity. Capillary action involves both adhesion and surface tension forces.

Body Temperature Pressure Saturated

a modified entrainment device which widens just after it's jet or nozzle, helps restore fluid pressure. Provides greater entrainment.

Tube that restores fluid velocity, lessens the effect of downstream pressure on fluid entrainment.

9/5(temperature in Celsius)+32

9/5(temperature in Fahrenheit-32)

the lowest possible temperature that can be achieved.

the temperature at which it's vapor pressure exceeds it's atmospheric pressure.

melting, freezing and sublimation. Melting: the changeover from a solid to a liquid state, Freezing: The changeover from a liquid to a solid due to extreme cold temperatures. Sublimation: Transition from a solid to a gaseous state without becoming a liquid first. This occurs because the vapor pressure is low enough for the intermediate liquid not to appear. Dry Ice is an example of sublimation.

the measurement of heat. The collision of molecules.

(Henry's Law) Volume of gas dissolved in a liquid is a function of it's solubility coefficient and it's partial pressure.

Gradient that causes gas flow in and out of the lungs. Prs= Palv-P(bs or ao)

keeps alveoli open. surfactant plays role in this

characteristic of strecthability.

How well an object recoils or returns to it's original shape after being stretched or damaged in someway

reduces surface tension. surfactant stabilizes alveoli by preventing collapse.

Total measurement of all forces combined. Total gas flow.

anatomic and alveolar dead space combined

the PaCO2 is less that (<) 35mmHg more CO2 is being blown off than is being produced.

the PaCO2 is more that (>) 45mmHg less CO2 is being blown off than is being produced.

Dead space in alveoli. Air that is ventilated but not profused. Gas is not being exchanged.

Air that is in the conductive zone that does not reach the alveoli. This air is not reaching the alveoli.
