Greenstick: fracture in a young, soft bone in which the bone bends and partially breaks.
Comminuted: broken into 2 or more pieces
Pathological: => of weakened / diseased bone (eg: osteoporosis)
Epiphysial: occurs during bone growth in a child
compression of nerves, blood vessels, and muscle inside a closed space (compartment) within the body.
leads to tissue death from lack of oxygenation due to the blood vessels being compressed by the raised pressure within the compartment.
Because the connective tissue that defines the compartment does not stretch, a small amount of bleeding into the compartment, or swelling of the muscles within the compartment, can cause the pressure to rise greatly.
purple discoloration of the skin => of a bruise
Procedure for splinting (mnemonic)?
Inflammation of paranasal sinuses (above & around ears & nose)
Partial thickness: (2nd) epidermis & Dermis. Super ouchy.
Full thickness: (3rd) no pain @ 3rd, plenty @ 2nd
Chemical: wet / dry
Definition of “Critical” Burns?
FT: to hands
FT: to feet
FT: to face
FT: to airway
FT: to genitals
FT: >10% of body area
PT: >30% of body area
Burns: with respiratory emergencies
Definition of “Moderate” Burns?
FT: >2% of body area
PT: 15% to 30% of body area
SF: >50% of body area
Definition of “Minor” Burns?
FT: <2% of body area
PT: <15% of body area
Tx for burns?
Immerse or run under cool sterile water / saline
<20% BSA = Wet Dressing
>20% BSA = Dry Dressing
Retrograde vs Anterograde memory loss?
Anterograde amnesia: loss of the ability to create new memories after the event
Retrograde amnesia: loss of memories created prior to the event
Bleeding in anterior chamber of the eye
fracture of the walls or floor of the eye orbit: Intraorbital material may be pushed out into one of the paranasal sinuses.
One lung collapses & compresses heart and other lung
Paper bag syndrome?
Traumatic Asphyxia: sudden, severe compression of the chest causing a massive increase in intrathoracic pressure resulting in a reversal of blood flow through the circulatory system (possibly damaging heart valves)
Often caused by holding your breath before impact
-> Narrowing pulse pressures
-> Muffled heart sounds
Membranous folds attaching intestines to the body cavity
Respiratory Syncytial Virus: lower airway illness
Effects of hypo- & hyperventilation?
Hypoventilation: respiratory acidosis & < hemoglobin affinity to O2
Hyperventilation: respiratory alkalosis & ^ hemoglobin affinity to O2
Excess CO2 in blood
OPA & NPA measurement?
OPA: corner of mouth to earlobe
NPA: tip of nose to tragus, diameter bit smaller than pinky finger of pt, right nostril
Most common cause of airway obstruction?
SPO2 & bag choice?
To reduce the risk of gastric inflation that might lead to regurgitation and aspiration of stomach contents?
recommend reductions in both volume and speed at which rescuers provide ventilations, but only if supplemental oxygen is provided.
