Case 1

Your patient is a 42-year-old woman who was pulled out of a backyard swimming pool.

It is a warm July day.

The time is 1523.

8 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

You see a woman supine on a stretcher.

Her eyes are closed, and her hair and clothing are wet.

You see no signs of breathing.

Her skin looks pale.

9 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

What memory aid can you use to evaluate the patient’s level of responsiveness?

10 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Assess Responsiveness

A = Alert

V = Responds to Verbal stimuli

P = Responds to Painful stimuli

U = Unresponsive

11 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

The patient is unresponsive.

What should be done next?

12 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Primary Survey

Perform a primary survey that starts with the assessment of the patient’s airway: A = Airway B = Breathing C = Circulation D = Defibrillation/disability E = Exposure

13 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

How will you open the patient’s airway?

14 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Airway

Unresponsive patient

Use the head tilt–chin lift maneuver to open the airway if no trauma is present.

Use a jaw-thrust without head-tilt maneuver if there is known or suspected trauma.

15 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

You see a small amount of pink fluid in the patient’s mouth.

What should be done now?

16 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

17 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

The patient’s airway is clear.

What should be done now?

18 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

The patient is not breathing.

How should you proceed?

19 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

Size and insert an oral airway. Begin positive pressure ventilation. Continue the primary survey.

20 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

Copyright © 2012 by Mosby, an imprint of Elsevier Inc. 25

Oral Airway: Insertion

Copyright © 2012 by Mosby, an imprint of Elsevier Inc. 26

Oral Airway: Insertion

27 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

An oral airway has been inserted.

The patient is still not breathing.

Should a nasal cannula be considered at this point?

28 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

When the use of a nasal cannula is indicated, what liter flow is recommended for use with this device?

What is the approximate oxygen concentration that can be delivered with a nasal cannula?

29 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Nasal Cannula

0.25 to 8 L/min flow

Oxygen concentration of approximately 22% to 45% (actual amount of inspired oxygen depends on ventilatory rate and depth)

30 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

Should a simple face mask be considered at this point?

31 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

When the use of a simple face mask is indicated, what liter flow is recommended for use with this device?

What is the approximate oxygen concentration that can be delivered with a simple face mask?

32 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Simple Face Mask

5 to 10 L/min flow

Inspired oxygen concentration of approximately 35% to 60%

The patient’s actual inspired oxygen concentration will vary, because the amount of air that mixes with supplemental oxygen is dependent on the patient’s inspiratory flow rate.

33 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Case 1

What percentage of oxygen can be delivered with a bag-mask device?

Copyright © 2012 by Mosby, an imprint of Elsevier Inc. 34

What methods can be used to verify the proper placement of the tracheal tube?

46 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.

Confirming Tube Placement Visualizing the passage of the tracheal tube between

the vocal cords Auscultating the presence of bilateral breath sounds Confirming the absence of sounds over the epigastrium

during ventilation Adequate chest rise with each ventilation Absence of vocal sounds after tracheal tube placement End-tidal carbon dioxide measurement (waveform

capnography is preferred) Verification with an esophageal detector device Chest radiography

47 Copyright © 2012 by Mosby, an imprint of Elsevier Inc.
