Module 3—Behaviour of Gases

Reflect and Connect

 

Respiratory therapists evaluate and care for patients who suffer from breathing problems due to chronic lung conditions, such as asthma and emphysema. They also work with people involved in motor vehicle collisions, people who have heart attacks, and premature infants.

 

Respiratory therapists continually work with gases, such as oxygen and carbon dioxide. They monitor lung capacity and work with patients to ensure they are breathing properly.

 

Read the transcript of an interview with a respiratory therapist to see how a knowledge of the pressure-volume relationship of gases is used in their work.

 

Reflect on the Big Picture

 

Compressed Gases

 

Throughout this module you will be asked to consider technologies that apply the use of one or more of the gas laws. For your combined unit and module assessment, you will prepare a response on a technology that applies one or more of the gas laws. To prepare your response, consider the following description of compressed gases. Refer to the Unit Assessment section for more information.

 

Review the technologies described in the case study on “Compressed Gases” on pages 159 and 160 in your textbook.

 

Which of the technologies in this case study involves a pressure-volume relationship? Describe how this relationship is involved in the operation of the technology. Save your answer in your course folder.
