Week 3 IO Flashcards
Intraosseous=
ridgid needle into the cavity of the bone to transport fluids to venous system
Most common IO site=
medial malleolus of distal tibia
You can identify the proximal epiphysis by palpating the condyles.
pediatric PT establish intraosseous access on the medial aspect of the proximal tibia=
site is from 2-3 fingerbreadths below the tibial tuberosity.
adult / geriatric PTs place the IO at=
distal part of the tibia 1-2 fingerbreadths above the medial malleolus.
Trocar=
sharp, pointed part of IO aiding in puncturing bone
Manual IO needles:
Jamshidi IO
EZ-IO T.A.L.O.N
Monoject IO=
COOK IO
Spring Loaded IOs:
Bone injection gun (BIG)=
Fast1=
IO Drill needle sizes:
15mm (pink) 3-39kg
25mm (blue) >3kg
45mm (yellow) >40kg
Complications of IO:
fracture, Infiltration (solution collects locally in tissues instead of canal), Growth plate damage, complete insertion/puncture, PE, Infection
Contraindications of IO:
fracture, osteogenesis imperfecta, osteoporosis, establishment of peripheral IV line
IO sites:
proximal tibia (~2 inches for stability)
proximal humorous (in peoples way)
distal tibia (easier for manual IO),
Sternal (for adults)
Distal femur (for kids)
IO pain→
flushing fluid into the bone is painful so admin/ 2% Lidocaine 20-40mg) to a conscious PT
Osmosis solute=
m-vt L→H
Simple diffusion=
m-vt of MOLECULES H→L
Facilitated diffusion most common w/?
glucose & insulin
Ph normal range
7.35 - 7.45
HaLden happens in
Lungs
BohR off in
the body ( the bull Bohr bucks off waste)
Chemoreceptors
receptors & monitors Ph (oxy & Co2)
Active transport=
molecules L→H w/ need of ATP “against concentration gradient
98% of K+ belongs
Intracellular
Hypertonic sol/=
creates a pull from the cells into the intravascular compartment (crenation= cells shrivel up)
Hypotonic sol/=
lower tenacity causes cells to swell → blood into the cells “hypo makes you a hippo”.
“Lysic” =
cell cut/killed
