Breath sound
Feel : air passes through nose and
mouth
Upper airway : clear/ maintainable,
not maintainable
Increase respiratory effort, inspiratory force/absent?
Snoring, stridor?
Retraction?

11. Breathing
RR
Respiratory effort
Tidal volume
Airway and lung sound
Pulse oximetry
 94% = adequate oxygenation
 < 94% airway intervention
 < 90% in 100% oxygen ( non
rebreathing mask  advanced
intervention : assisted ventilation

21. Tertiary assessment
 Laboratory : ABG, VBG, Hb, SVO2 sat,
HCO3, lactate,
 Radiography : CXR, echocardiography
 Exhale CO2, PEFR, CVP
 Emphasize : Anytime you identify a life
threatening condition, initiate appropriate
care immediately
21

22. Assess
Action Categorize
Decide
If you recognize a life threatening condition at any time,
immediately begin life saving intervention and
activate the emergency response system
22

23. Summary
PALS guideline AHA 2008
23

24. Signs of life threatening condition
Airway Complete or severe AO
Breathing Apnea, significant work of
breathing
Circulation Absent pulse, poor
perfusion, hypotension,
bradycardia
Disability Unresponsiveness, depress
conscious
Exposure Significant hypothermia,
bleeding, purpura,
abdominal distension due
to bleeding
24

25. Life saving intervention
ACTION
 ABC/CPR
 100% oxygen
 Assisted ventilation :
bag mask, ETT
 Cardiac and
respiratory monitoring
: EKG, pulse oximetry
 Intravenous / I/O
 Bolus isotonic
crystalloid
 Lab study : DTX, ABG
 Drugs
 Electrical therapy
25

26. New recommendation : Bag & mask
ventilation :
E-C clamp
Give 2 breath chest move?
(12-20 breath/min for child)
26

27. 27

28. PALS and neonatal update
Good PALS begin with good BLS
Lay person (1 choice) : 30:2 (8 yr)
HCP : 1 rescue : 30:2
HCP : 2 rescue : 15:2 (teenage)
Child chest compression > 1 or 2 hands

29. Chest compression

32. Coronary Perfusion Pressure Improves With Sequential
Compressions
CPP at 5:1 ratio
Survival with 15:2
CPP at 15:2 ratio
32

33. “Continue CPR as much as
possible except rhythm check”
33

34. Key change in BLS
Effective rescue breath and visualization
of chest rising
Fully recoil chest
Single shock for VF
(2 J/kg mono-bi phasic continue CPR,
rhythm check only at 2 min)
AED 1-8 years old
34

35. Categorize
 Determine the type and severity
Type Severity
Respiratory - Upper airway obstruction -Respiratory
- Lower airway obstruction distress
- lung parenchymal disease -Respiratory failure
- Disorder control of breathing
Circulatory - Hypovolemic shock -Compensated
- Obstructive shock shock
- Distributive shock -Hypotensive shock
- Cardiogenic shock

43. Prehospital Tracheal Intubation vs Bag-Mask
Ventilation
Bag-mask
ventilation : as
effective as
intubation if
transport time is
short
Need training and
experience
Must confirmation of
tube position
Monitoring
43

44. Use of Cuffed Endotracheal Tubes
In-hospital setting, a cuffed ETT : as
safe as an uncuffed tube for infants
(except the newborn) and children
Keep cuff inflation pressure <20 cm
H2O
Cuffed ETT size (mm) = (age (yr) /4) + 3
Uncuff size (mm): (age (yr) /4) + 4
Depth : age (yr)/2 + 12
44

45. Insertion of the Laryngeal Mask Airway in
Children
 The LMA consists of a tube
with a cuffed mask at the
distal end.
 The LMA is blindly
introduced into the
pharynx until resistance is
met; the cuff is then
inflated and ventilation
assessed.
45

46. Verification of Endotracheal Tube Placement
bilateral chest movement and listen
for equal breath sounds over both
lung fields
gastric insufflation sounds
exhaled CO2
pulse oximeter
direct laryngoscopy
chest x-ray
46

47. Colorimetric Exhaled CO2 Detector
Colorimetric
exhaled CO2
detector device
changes color (from
purple to yellow)
with detection of
exhaled CO2
“additional”
confirmation with
clinical assessment
