Compartment Syndrome: Rx 6 Ps:

= When injured, soft tissues within the compartment swell. Reduces blood flow to muscles and nerve tissues Deep, burning pain out of proportion to apparent injury. Leg most common location = make pain tollerable/take edge off = Pain – Pallor (loss of collor/ pale)– Paralysis (lack m-nt) – Paresthesia (lack of sense) – Pressure (feeling of tension) – Pulses (diminished or absent)

Controlled hemo/ fluid dosing

20mL/Kg Warm NS

Ejection Fraction (EF): <45% usually indicates: <30%:

= Ratio of blood pumped from the ventricle to the amount remaining @ the end of diastole/ %of blood pumped out from ventricle (60-70%) =<45% usually indicates in or going to CHF =<30% in CHF & chronic cardiac crip on oxy

End-tidal gradient= Difference between partial pressure of arterial CO2(PaCO2) & end-tidal CO2(ETCO2). Formula=

PaCO2 - ETCO2 = End - Formula gradient

ETCO2 levels <10 mmHg indicates

NO ROSC

ETT size range~

Adults (6.0-9.0) women~7-8 & man~8-9 Pedi tubes(2.5-5.5)

ETCO2 Lvs in head-injured intubated PT shouldn't drop below: When vent/ing a adult PT, each breath should have tidal volume of:

= 30 mmHg = approximately 500mL

FIO2% on nasal canula formula

(lpm x 4) + 20 ,ex 1lpm=24%

Fluid accounts for ~% of the body’s weight, Only ~% of the fluid is contained in our vascular system

= 60% of the body’s weight, Only about 7% of the fluid is contained in our vascular system

fluid replacement after perfusion rule: 4 2 1rule/ formula :

=back to normovolemia Used for every hr after to maintain = [A] 4ml/kg 1st 10 [B]2m/Kg 2nd 10kg [C]1ml/kG after per hour Used for every hour after to maintain

Force: Force formula:

= force related to a objects mass(weight) and/or achange in velocity = mass x Acceleration

Handtevy=

your hand 1,3,5,7,9 10,15,20,25,30→ weight in pedis

calculate alveolar volume, minute volume, alveolar minute volume?

= Tidal Volume - Dead Space =RR x Tidal Volume = Alveolar Volume x RR

How to estimate PEDI ET tube size: Uncuffed Cuffed

Uncuffed ET: (Age /4) + 4 OR (Age + 16) /4 Cuffed ET = (Age /4) + 3.5

How to estimate pedi weight

(Age + 4) x 2 = Approximate weight in kg (Old Way) (Age x 3) + 7 = Approximate weight in kg (New Way

hypoglycemic with PEDIs trick: hypoglycemia Rx for neonate: hypoglycemia Rx for infant:

= Lots of sick kids hypoglycemic so use bone marrow for BGL = <45BGL neonate = <60BGL infant

If you were administering isotonic crystalloid solutions, how much would move out of the intravascular compartment within 1 hour?

2/3s would move out

Kinetic energy: Kinetic Energy form:

=energy of a object in motion (by objects mass & its velocity = (Mass x Velocity ^2)/ 2 ½ x mv^2

Lbs→ Kg=

of pounds / 2.2

Lightning can still strike you if proximity up to:

up to 50yrds can strike you

Moderate criteria) Superficial: Partial thickness burns: Full thickness burns:

= BSA >50% = BSA <30% = BSA <10%

Normal blood pH range=

7.35 - 7.45 mmHg

oxygen saturation form=

O2 content / O2 capacity x 100%

Pedi intubation ETT location=

ETT Insertion is 2-3 cm below the vocal cords

Phrenic nerve location

C-3-5

Pulse pressure: Pulse pressure signifies: Pulse pressure <25 mmHg may be seen w/

= dif/ between DBP & SBP pressures (PP= SBP-DBP) = amount of force the heart generates with each contraction = PTs w/ sings of shock

Respiration ratio=

1 sec inhalation 2 sec exhalation

RSI Ideal Body Weight) Men formula Women formula

Men= 50 kg + (2.3 kg X (Height (in) - 60) Women= 45.5 kg + (2.3 kg X (Height (in) - 60)

Rule of palm:

use of PT hand = 1% of BSA (burns <10%)

"rule of thumb" for estimating the proper depth of an ETT=

Depth should be ~3x ETT size

Stroke volume: 3 factors that affect stroke volume:

= amount of blood ejected by heart in 1 contraction, varies 60-100mLs w/ average 70mL = preload, afterload, & contractility

Suction catheter size w/ ETT~ form:

ETT# x2

Suctioning time limits:

Adults 15 secs max, Children= 10 secs max, Infants=5 secs max, ET/Trach tube= 5-10 secs max

The blood volume of an infant or young child is proportionally: Population most at risk for trauma & trauma death:

= ~20%> than that of an adult = Young adult male

Triplicate method: 6 sec method: R to R small box method: R to R big box method:

= for HR> Big box RR descends 300,150,100,75,50,50,43,38 = Count # of complexes in a 6-sec strip X 10 = Count small boxes between R waves then /1500 EX: 1500 / 22 = 68 = (only regular rhythm) Count big boxes between R waves then divide 300 by this number EX 300 / 4 = 75

Ventri mask oxy%s:

24%, 28%, 35%, & 40%.

JumpSTART made for: At what age do we use JumpSTART vs. START:
