Blood:
Plasma:
Leukocytes:
Erythrocytes:
= Mixture of water, cells, proteins, & suspended elements.
= makes up 55% of the blood volume
= WBC & platelets make up the “Buffy Coat”
= RBC make up 45%
Lightning can still strike you if proximity up to:
up to 50yrds can strike you
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
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)
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
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
Hypovolemia Rx) If hemorrhage can be controlled:
If hemorrhage cannot be controlled:
Med for Sig/hemorrhage, in/external (after external controlled)
= IV/IO therapy (don’t delay transport) can administer 20 mL/kg bolus.
=administer just enough IV fluid to obtain a radial pulse (permissive hypotension therapy!)NO MORE SBP 80-90 (IV fluids Warm)
= Tranexamic Acid (TXA) Adult 1G/10 mins (mix in 50 mL of NS) follwed w/ 1G/8Hrs (500 mL bag) & Pediatric Not recommended
Burns) Wallace Rule of 9s) used only for:
Adult %s:
infants (0-1):
Form:
= burns >10%
= 1 genitals, 9 head thoracic & ABDMN, distal anterior (applies to other areas) arm 4 ½
= head 18, arm 9, legs 13.5, 18 front thoracic & ABDMN
= # of child -1 > take away from head then give to each leg (Applicable up 10y/o) For every year beyond age 1, subtract 1 from head / that # & add it evenly between the 2 legs.
Orthostatic hypotension
PT’s BP drops 20 HR+20 when moved from supine to a seated position
Cardiac depolarization:
RP of Ac:
RP of Cc:
Phases 0-4 of Cc:
= reversal charges of cell membrane inside becomes + & outside -,
= -60 slow Na & fast Ca -40
= -90 Na & -85 gap Junctions fast Na influxes
= 0 depolar, 1 early repolar, 2 plateau + for +, 3 K pumps, 4 refractory
(ECG Horizontal Boxes) small box is how long
5 small boxes:
Each large box is how long
= 0.04 sec
= 1 large box
= 0.20 sec
(ECG Vertical Boxes) Each small box is & what:
5 small boxes equal:
Each large box is:
2 large boxes equal
= Each small box 1 mm & 0.1mV
= 1 large box
= 0.5 mV & 5mm
= 1mV & 10mm
T wave represents:
T wave amplitude:
= Repolarization of ventricles
= <5mm in LL <10mm in precordial
A normal P wave in Precordial leads should be:
A normal P wave Limb leads should be:
= nice & round w/ amplitude <1.5mm
= nice & round w/ amplitude <2.5mm
P wave) Limb leads amplitude:
Precordial “chest” leads amplitude:
= <2.5mm in limb leads Avl (2.5mV)
= <1.5mm in precordial (1.5mV)
(ECG Paper) (Horizontal Boxes) small box duration:
5 small boxes makes:
Each large box duration:
(Vertical Boxes) Each small box volt & measurement:
5 small boxes makes:
Each large box voltage:
2 large boxes equivalent:
= 0.04 sec
= 1 large box
= 0.20 sec
= 0.1 mV & 1 mm
= 1 large box
= 0.5 mV
= 1 mV & 10mm
