What would you expect with this patient's O2 Hemoglobin dissociation curve?
Examify | Smart Grades | Latest update
✓ A patient who received mass transfusion
✓
✓ Would shift left due to increased oxygen carrying. ARDS, Respiratory acidosis, and
sepsis all are associated with acidosis, lower pH, higher levels of CO2, which would
cause a right shift
When it comes to making ATP during aerobic respiration, why is oxygen
necessary?
✓ Oxygen is the final electron acceptor in the electron transport chain
✓
✓ High-energy electrons go through the electron transport chain in a series of
exe3rgonic redox reactions. Ultimately used to produce ATP.
Which of the following methods is the least effective way to confirm
endotracheal tube placement?
End Tidal CO2 capnometry
Fogging in the tube
Direct visualization between the vocal cords
Bilateral equal lung sounds
✓ Fogging in the tube
What is the gold-standard to confirm ETT placement?
✓ Gas will diffuse from high pressure to low pressure
✓
✓ Higher O2 concentration in alveoli will diffuse to capillaries, which has lower
concentrations of O2
Acronym to consider for surgical cric considerations
✓ SMART
✓ Surgery of Neck
✓ Mass
✓ Access to the neck - obesity, Limited ROM
✓ Radiation
✓ Tumor
Acronym to consider when predicting a difficult airway
✓ HEAVEN
✓ Hypoxemia
✓ Extremes of size - obese pt, petite pt.
✓ Anatomic disruption/obstruction
✓ Vomit/blood/fluid
✓ Exsanguination- bled out so much they can't keep SpO2 up
✓ Neck mobility/neuro injury
Mallampati score vs Cormack-Lenane score
✓ Mallampati is direct visualization of the oral cavity and oropharynx
✓ Cormack-Lenane score is direct visualization of the pharynx and glottis with
laryngoscope
