Airway Tips and Tricks Your Patient Cant Live Without!
Eastern OR EMS Conference 2015
What we are going to talk about…
• Better….– Positioning
– Oxygenation
– Facemask Seal
– Ventilation
– Nasal ETT
– Oral ETT
– Planning
• Better resources– 5 blogs and podcasts that will change what you do!
BETTER POSITIONING
Tip #1:
Better Positioning
Elevate the trunk 20-30 degrees!
KEY POINT: Still put towels under shoulders for infants!
BETTER OXYGENATION
Tip #1:
What does Preoxygenation mean to you?
What the anesthesia world thinks of it
• SPO2 > 94% before apnea WITH preoxygenation efforts.
– Min of 3 minutes on well fitted NRB at flow rates > 15 LPM
OR
– 8-10 full inhalation/exhaltion breaths on 100% Oxygen
– Nitrogen Washout
Nitrogen Washout and the Oxygen Resovoir
• Normal FIO2 approx. .21-.24 (21-24%)– Remainder is Nitrogen, CO2, and other gasses
• Tidal Volume is 600-800 cc– “Dead Air Space” is approx. 150 cc
• If we replace that inert gas in the dead air space with 100% Oxygen, what happens?– “Nitrogen Washout”
– Dead Air Space (95%)
– Plasma (5%)
KEY POINT
• SPO2 >94 % WITHOUT Preoxygenation means NOTHING!
Why its important: “Safe Apnea”
What is Desaturation?
• Desaturation is defined as saturation below 88%
• Safe Apnea period
– Time to 90% AFTER preoxygenation
How quick can desaturation occur?
Between IMMEDIATELY and 8 minutes.
Who is at risk?
Introducing NO DESAT
NO DESAT (15 + LPM via NC)
+LPM
How long can this be done?
• At least 100 min– Nielsen ND, Kjaergaard B, Koefoed-Nielsen J, et al. Apneic oxygenation
combined with extracorporeal arteriovenous carbon dioxide removal provides sufficient gas exchange in experimental lung injury. ASAIO J. 2008;54:401-405
– Enghoff H, Holmdahl MH, Risholm L. Oxygen uptake in human lungs without spontaneous or artificial pulmonary ventilation. Acta ChirScand. 1952;103:293-301.
– Holmdahl MH. Pulmonary uptake of oxygen, acid-base metabolism, and circulation during prolonged apnoea. Acta Chir Scand Suppl. 1956;212:1-128..
Can you not bag at all?
• Answer: “Depends”
• Considerations: – Obesity
– Shunt Physiology
– Shock
• What should you do?– Cautious Bagging
– CPAP?
– Bagging with PEEP Valve?
KEY POINT:
• This works best when you have excellent airway positioning!
BETTER FACE MASK SEAL
Tip # 3:
Better Face Mask Seal ?
At least 8 good full tidal volume breaths is “Ideal”
E-C Techniques
The “T-E” Technique
Which is better?
• In every study: 2 handed techniques out performed 1 handed techniques.
• The T-E technique marginally delivered better airway pressures and tidal volumes over the E-C technique.
• TE produced less failed breaths
Nu MASK
• BLS difficult airway Device
• Cheap and easy
Using a Pedi Mask
Weyland-Yutani Face Mask
BETTER VENTILATION
Tip # 4
OPA + NPA x2
• Less Turbulant Flow
• Better Tidal Volume
• Estimated time to placement is 9-10 seconds.
The “Super Plug”
Monitor your airway pressures
Key Point!!!
• Airway pressures > 25 cmH2O can cause gastric Distention
• Gastric Distention can cause vomiting
• Vomiting can cause aspiration
• Aspiration causes aspiration pneumonia in most patients
• Aspiration Pneumonia kills 40-70% of its patients
• Don’t give ventilations at pressures > 25 cmH20
BETTER NASAL INTUBATION
Tip # 4:
Nasal ETT
Tennessee Technique
Close up view
BETTER ORAL INTUBATION
Tip # 5:
Medics: Involve your BLS personnel
KIWI GRIP
Pistol Grip

BETTER PLANNING
Tip #6:
Better Planning
Better Planning
EMCRIT.org CRICON
Better Planning
Checklists!
Checklists and CRM save lives
www.projectcheck.org
• Checklist are NOT – A protocol– A procedural checklist – An algorithm– A teaching tool– Not an credentialing tool (NREMT)
• Checklist do:– Red Label items– Have Pause Points– Have “Challenge and response”– Are TEAM DRIVEN– Are REALITY BASED
