2. How predictive is Mallampati Classification of a straightforward
   tracheal intubation?

Answer 2

Low PPV

Question 3

3. Why was there non-oxygenation?

Answer 3

• Obstructed airway
• Constricted airway
• Paralysis
• Non-Perfusion

Question 4

4. Why was atropine given?

Answer 4

Postive arrhythmic - she was bradycardic so they needed to raise her HR.

• to inhibit cardiac dysrhythmias, bradycardia and hypertension resulting from excessive vagal stimulation and decreased mucus secretions.

Question 5

5. What were the critical time points?

Answer 5

5 mins - pt O2 sats at 40 mins
6-8 mins - 1st attempt at intubation
10 mins - pt O2 sats at 40% for 5 mins
35 mins - Finally intubated her with an endotracheal tube and sats improved to 90%

a. What even occurred at O2 saturation fall? <70%?
- the first oral airway was inserted

b. What even was 3 min. after O2 saturation <70%?
- the ENT surgeon entered the room

Question 6

Which three organs use the most oxygen?

Answer 6

Skeletal muscle
Splanchnic (gut)
Cerebral (brain)

Question 7

What happens if hypoxic?

Answer 7

• Early compensation:
• – cyanosis, feel breathless, lactic acid production
• Peripheral vasodilation
• Pulmonary vasoconstriction
• Cerebral
• – Early Cell death
• – Confusion
• – Worsening cell death
• – Hypoxic brain damage

3 mins of your brain without oxygen is a BIG problem.
