Purpose of Module:
The purpose of this module is to learn about the basic components of oxygen delivery systems, their indications, and complications and how they are integrated into the Emergency Medical Services.

Time to complete Oxygen Therapy: 1 hour

Directions for using the Oxygen Therapy module:

* You must spend at least 1/2 hour doing hands-on training.
1. Read the training Objectives
2. Review Brady Emergency Care, Eighth Edition pp. 123-136.
3. Watch the video tape "Mosby’s EMT-BASIC VIDEO SERIES, Lesson 2-1 Airway".
4. Use the MED EMT computer based training software and complete Chapter 9 Section 7.
5. Initiate Oxygen Therapy on an airway mannequin. Use the Airway, Oxygen, and Ventilation Checklist and an adult mannequin provided.
6. Take the posttest.
7. Give module back to instructor or person in charge.

Training Objectives:

1. Define and demonstrate how to employ the components of an oxygen delivery system.
2. Identify a non-rebreather facemask, state the oxygen flow requirements needed for its use and demonstrate the proper use on a patient.
3. Describe the indications for using a nasal cannula versus a non-rebreather facemask and demonstrate the proper use on a patient.
4. Identify a nasal cannula and state the flow requirements needed for its use.
5. Explain the rationale for basic life support artificial ventilation and air way protective skills taking priority over most other basic life support skills.
6. Explain the rationale for providing adequate oxygenation through high-inspired oxygen concentrations to patients who, in the past, may have received low concentrations.

Activities to Perform:

1. Watch the video tape "Mosby’s EMT-BASIC VIDEO SERIES, Lesson 2-1 Airway".
2. Use the MED EMT computer based training software and complete Chapter 9 Section 7.
3. Use the Oxygen Administration Checklist to verify your steps for providing oxygen to a patient. Ask a classroom facilitator to provide you with an oxygen tank, regulator, nasal cannula and non-rebreather facemask. Practice using an adult mannequin.
4. Take the posttest to give yourself feedback on this module.

Posttest:

1. A full tank of oxygen contains how many pounds per square inch (psi)?
A. 1,100
B. 2,100
C. 3,100
D. Varies with different sizes of tanks.

2. Although done rarely, oxygen occasionally is humidified to prevent:
A. damage to the flowmeter.
B. damage to the pressure gauge.
C. separation of the oxygen molecules.
D. drying of the patient’s mucous membranes.

3. A safe residual amount in an oxygen cylinder is:
A. 500 psi.
B. 2,000 psi.
C. 500 liters per minute.
D. 2,000 liters per minute.

4. Oxygen is a medical gas. What color tank is it stored in?
A. nasal cannula.
B. venturi mask.
C. simple face mask.
D. non-rebreathing face mask.

5. The maximum flow rate used with a nasal cannula is how man liters per minute?
A. 2
B. 4
C. 6
D. 8
