Positioning
THE HUMAN AIRWAY:
AIRWAY: A CONTINUUM…
• Awake & Alert: No Intervention
• Inadequate?
– Positioning
– Head Tilt / Jaw Thrust
– Nasopharyngeal Airway
– Oropharyngeal Airway
– Bag Valve Mask Ventilation
– Supraglottic Airway (LMA, etc)
– Endotracheal Intubation
• “Impossible?”  then one of the following…
– Jet Insufflation
– Surgical Airway: Cricothyroidotomy > 8-12 yo
Bagging a Patient:
Head--Tilt Chin Lift
Head
• Extend the patient’s head slightly (‘sniffing position’)
• Do NOT do this with C-Spine precautions
• Jaw Thrust
• OK to do this with C-Spine precautions
 ‘Head-Tilt Jaw-Thrust’

facial abrasions, breathing poorly, slightly
cyanotic, and with a weak femoral pulse.

The ACLS “Surveys”
Primary
•

•
•
A-B-C  C-A-B!!!
Call for help; get AED
If alone
alone, call 911
911, get AED  follow prompts
No AED  CPR x 30 compressions
Airway: assess & open (head-tilt, jaw thrust)
Breathing: provide x2
Repeat 30/2
Defibrillate: when AED or Life-Pak arrives
The ACLS “Surveys”
Other ACLS Changes…
• No cricoid pressure for lay or healthcare BLS
• No more ‘look-listen-feel’  ‘hands-only CPR’
• Even for healthcare providers, empahsis is on
early quality CPR
– Airway has been un-throwned!!!
– But not forgotten…

Review Question
In an adult patient, what are the
answers to the following as they relate
to CPR?
• Compression Rate
• Depth of Compressions
• Ventilation to Compression Ratio
• UN-Intubated
• Intubated
• Ribs Cracking?
Case (continued)
Your patient is unresponsive.
A “Code” is called & CPR is ongoing.
You attach your unresponsive patient to the
cardiac monitor and see the following:

The SEIZING Patient
• Protect from HARM!
The SEIZING Patient (cont’d)
• Benzodiazepine: LORAZEPAM 2 mg IV
(may repeat every min up to 8 mg)
• Trendelenberg – suction – airway (NP)
• DILANTIN: 15-18 mg/kg IV load at 50
• Oxygen – IV access
• Fingerstick glucose – give DEXTROSE if low
mg per min
• Others: MAGNESIUM, more DILANTIN,
PHENOBARBITAL, PROPOFOL, etc.
