FP-C Flashcards
What does HEAVEN stand for
H-Hypoxia
E-Extremes of size
A-anatomic disruption/obstruction
V-vomit, blood, secretions in airway
E-exsanguination
N-neck mobility
What are the 8 P’s of intubation
Preparation
position
pre-oxygenation
pre-treatment
paralysis and induction
protection and positioning
placement and proof
post intubation management
What are the indications for an advanced airway
Can they follow commands
can they control secretions
what is their clinical coarse.
What is the Larson maneuver
placing firm pressure inward behind both earlobes while doing a jaw lift. This will help relax the vocal cords due to spasming.
What are the 3 airway assessments commonly utilized
3-3-2
Mallampati
Cormack-Lehane score
How to determine shock index
pulse rate / systolic BP
>0.9 = high shock index
Is a paralytic contraindicated if you can not oxygenate or ventilate
yes
How to determine ETT size for pediatric (greater than 1 yr)
(age + 16) /4
How to calculate Ideal body weight (IBW)
M- (# of inches above 60 x 2.3) + 50
F- (# of inches above 60 x 2.3) + 45.5
Oxyhemoglobin disassociation curve
Haldane effect
Left shift
Lowered PH, Temp, 2-3-DPG production, PaO2
Higher affinity for O2
poor cellular perfusion, less CO2 removal
Oxyhemoglobin disassociation curve
Bohr effect
Right shift
Raised PH, Temp, PaO2, 2-3-DPG production
Low affinity for O2
poor lung perfusion, removes more CO2
What is brown-Sequard syndrome
Hemi section of cord that is very rare and causes ipsilateral loss of motor position and vibratory sense with contralateral loss of pain and temperature perception.
What is central cord syndrome
Greater motor weakness in upper extremities than lower with varying degree of sensory loss.
What is anterior cord syndrome
displacement of bony fragments into the anterior part of the spinal cord. the result of flexion injuries or fractures.
complete motor, pain, and temp loss below the lesion with sparing proprioception vibration, and touch
What is Cushings triad
-increased systolic blood pressure
-decreased diastolic blood pressure
-bradycardia
Acute respiratory distress syndrome (ARDS) vent settings
-lower tidal volume 4-6 ml/kg
-increased respiratory rate
-normal PEEP 5-10
goal is to keep initial minute volume
What is subfalcine herniation
midline shift of the brain
What is SCIWORA syndrome
-spinal cord injury without radiographic abnormality.
-spinal shock/contusion
What is an epidural bleed.
-a bleed located between the skull and dura mater and pushes the dura mater into the brain.
- concave shape or looks like a football.
- edge will be smooth.
what is a subdural bleed
- a bleed that is located between the dura mater and the arachnoid and pushes the dura mater up towards the skull.
- concave shaper or look like a crescent moon.
-edge will be jagged.
What do you treat 1st in a TBI patient with a multisystem trauma.
-Treat the brain first by maintaining a MAP >90 mmHg.
-then you can assess the multisystem trauma.
What is the main goal with a TBI patient
Prevent the 3 H’s
1- hypoxia
2-hypotension
3-hyperventilation
what is the formula for tidal volume
-Based off of ideal body weight.
-6-8 ml/kg normally
-4-6 ml/kg for ARDS pt’s
what is the target minute ventilation formula, and breaths/minute to maintain that formula.
100 ml/kg/min 80 kg pt
100 x 80 = 8000 ml/min
tidal volume is 80 x 6 ml/kg = 480 ml
8000/480= 16.6 breaths/min
How do you determine anatomical dead space.
-1ml x ideal body weight in lbs
or 150 ml/breath
