Therapeutics I Review

Front

What should gases for medical use be free of?

Back

Gases for medical use should be free of particulates, moisture, and oil.

Front

Which gas is used to reverse pulmonary vasoconstriction?

Back

Boyle's gas is used to reverse pulmonary vasoconstriction.

Front

What is atelectasis?

Back

Atelectasis is the collapse of part or all of a lung, and it is not an example of increased dead space.

Front

Can oxygen be administered with a simple mask at 3 lpm?

Back

No, oxygen cannot be effectively administered with a simple mask at 3 lpm.

Front

How does an Oxymizer increase FiO2 compared to other cannulas?

Back

An Oxymizer increases FiO2 by increasing the size of the oxygen reservoir.

Front

Define dead space in the context of respiratory physiology.

Back

Dead space refers to areas of the respiratory system where gas exchange does not occur.

Front

What is the significance of maintaining moisture-free gases in medical applications?

Back

Moisture-free gases prevent condensation and potential contamination in medical equipment.

Front

Explain the concept of pulmonary vasoconstriction.

Back

Pulmonary vasoconstriction is the narrowing of blood vessels in the lungs, which can affect oxygen exchange.

Front

What is the role of Boyle's law in respiratory therapy?

Back

Boyle's law states that the pressure of a gas is inversely proportional to its volume, which is crucial in understanding how gases behave in the lungs.

Front

What are the potential consequences of administering contaminated gases?

Back

Contaminated gases can lead to infections, inflammation, and impaired gas exchange.
