injured pt? (2) - correct answer ABG, BG
What is the single most important indicator of critical illness? (hint: it's a
vital sign) - correct answer Tachypnea
Increase in depth of breathing - correct answer Kussmaul/hyperpnea
Increase in depth of breathing, also called Kussmaul or hyperpnea, may
indicate what severe acid/base abnormality? - correct answer severe
metabolic acidosis
Periodic breathing with apnea or hypopnea - correct answer Cheyne-Stokes
Periodic breathing with apnea or hypopnea (Cheyne-stokes breathing) may
indicate what? - correct answer Severe brainstem injury or cardiac
dysfunction
When you assess the A (airway) in a critically ill patient, what are you
look/listening/feeling for? - correct answer *LOOK:* cyanosis, altered
respiratory pattern and rate, use of accessory respiratory muscles, tracheal
tug, paradoxical breathing, altered consciousness
*LISTEN:* noisy breathing (grunting, stridor, wheezing, gurgling); silence
indicates complete obstruction
*FEEL:* decreased or absent airflow
When you assess the B (breathing) in a critically ill patient, what are you
look/listening/feeling for? - correct answer *LOOK:* cyanosis, altered
respiratory pattern and rate, use of accessory respiratory muscles, tracheal
tug, paradoxical breathing, *equality and depth of breaths, O2 sats*,
altered consciousness
*LISTEN:* dyspnea, inability to talk, noisy breathing, dullness to percussion,
auscultation of breath sounds
*FEEL:* symmetry and extent of chest movements, position of trachea,
crepitus, abd. distension
What is pulsus paradoxus? - correct answer decrease in >10mmHG in
systole during inspiration
When you assess the C (circulation) in a critically ill patient, what are you
look/listening/feeling for? - correct answer *LOOK:* reduced peripheral
perfusion
,(pallor) and delayed cap refill, hemorrhage (obvious or concealed), AMS,
dyspnea, decreased urine output, jugular venous distension
*LISTEN:* altered heart sounds, carotid bruits
*FEEL:* precordial cardiac pulsation, central and peripheral pulses
(assessing rate, quality, regularity, symmetry), cool extremities
How do you intubate in someone with a cervical spine injury? - correct
answer Immobilize with C-collar, then elevate mandible/open the mouth
Which airway is not used if airway reflexes are intact, as it may cause
gagging/laryngospasm/emesis: nasopharyngeal airway or oropharyngeal
airway? - correct answer oropharyngeal airway
Oropharyngeal airway - correct answer a curved device inserted through
the patient's mouth into the pharynx to help maintain an open airway
Nasopharyngeal airway - correct answer Airway adjunct inserted into the
nostril of an unresponsive patient, or a patient with an altered level of
consciousness who is unable to maintain airway patency independently.
When is a nasopharyngeal airway contraindicated? - correct answer -LeFort II
or III fracture
-*Basilar skull fracture*
-CSF rhinorrhea
-Raccoon eyes
-Periorbital edema
-*Coagulopathy*
-Previous transsphenoidal hypophysectomy or Caldwell-Luc procedure
MC cause of airway obstruction - correct answer pt's tongue
When is bag mask ventilation indicated? - correct answer
Pt apneic Spontaneous tidal volumes are inadequate
Reduce work of breathing
Hypoxemia is associated with poor spontaneous ventilation
In bag mask ventilation, how many bpm? how long should the breaths be
over? - correct answer 10-12 bpms over 1 second for each breath
Risks to too many breaths with bag mask resuscitation? - correct answer
hyperventilation
respiratory
alkalemia gastric
distension
What % O2 should be delivered in bag mask ventilation? - correct answer
100%
,Sellick maneuver - correct answer cricoid pressure
Indications for tracheal intubation - correct answer airway
protection relief of obstruction
provision of mechanical ventilator and O2
therapy respiratory failure
shock
hyperventilati
on
reduction of the work of breathing
facilitation of
suctioning/pulmonary toilet
Maximum lidocaine dose - correct answer 300mg
Name the NMBs used for intubation - correct answer
succinylcholine vecuronium/rocuronium/cisatracurium
Which NMB will you see fasciculations with? - correct answer succinylcholine
When is succinylcholine contraindicated? - correct answer ocular injury,
head injury, hyperkalemia, burn/crush/rhabdo
may precipitate malignant hyperthermia
What are the benefits to using sux instead of rocuronium? - correct answer
Shorter duration of action (useful if you need to do a mental status exam
soon)
What are the benefits to using rocuronium over sux? - correct answer Less
side effects, longer duration of action
Intubation can increase intracranial pressure. In a PT with already intracranial
htn, what medicine can be given to blunt this response? - correct answer
Lidocaine 1-1.5mg/kg
Compression to ventilation ratio during cpr - correct answer 30:2
Should the chest recoil completely between compressions? - correct answer
Yes
What is often the first sign of rosc? - correct answer Rapid increase in end-
tidal CO2
Closed chest compressions reflects what fraction of normal cardiac output? -
correct answer 1/3
What is the ttm temperature range post cardiac arrest? - correct answer
32-36 (89.6- 96.8)
, How do you decool after ttm? - correct answer 0.25 Celsius per hr until
temp is 37 Volume replete, electrolyte replete
