Airway Management Flashcards
Why are masks clear
Condensation
Lip color
Secretions
Bleeding
Regurgitation
Corneal abrasion mitigation
SpO2 on ring finger
Badge on pants
Contraindication for nasal airway
Basilar skull fracture
Anticoagulated patients
Laryngoscopy vs endotracheal intubation
Placement of breathing tube in the trachea
Vs
Visualizing larynx with laryngoscope
How to test ETT cuff
Create suction
Purpose of Murphy’s eye
Prevent occlusion from secretions
Minimizes left lung collapse with RT mainstem
Main type of cuff
High volume
Low pressure
Downside to oral Reye
Increased turbulence and resistance due to acute bend
Reasons to use a miller
Narrow interincisor distance
Less neck range of motion
How long can a patient be sustained after 5 min preoxygenation?
10 min of apnea lol
We want expired O2 > 80%
Goal is to replace nitrogen volume in the lung (69% of FRC)
Burp maneuver
Backward
Upward
Rightward
Pressure
Cormack and Lehane grading scale is based on what?
Degree of glottic exposure
3&4 predict difficult intubation
If first attempt at intubation is unsuccessful then what
Change at least one thing!!
Blade
Patient position
Self position
Tricks with nasal intubation
Warm the tube
Administer topical vasoconstrictor in preop
Do not force
RSI standards
Preoxygenate
Sellick maneuver
IV induction
Succinylcholine
No manual ventilation
Larsons maneuver
Forceful pressure applied to the area between the mastoid process, ramus of mandible and the skull base
Managing laryngospasm
Jaw thrust
Larsons maneuver
Positive pressure ventilation
Deepen anesthesia
20 mg succinylcholine
Risk factors for negative pressure pulmonary edema
Young
Male
Muscular
Describe neg pressure pulmonary edema
Pressure created against a closed glottis will increase permeability of the capillary membrane
Nasal airway sizing
External auditory meatus
Risk factors for aspiration
Trauma
Obesity/pregnancy
Acute abdomen
Head injury/AMS
Diabetes/delayed gastric emptying
GERD
Active vomiting/pharyngeal bleeding
