WEEK9- Assisting the paramedic Flashcards
what is an airway filter
protects the patient, breathing system, and equipment from potential microbial contamination.
efficiency= 99+ percent
also acts as a physical barrier between airway adjunct and catheter mount
what does hme stand for
heat and moisture exchanger
where is the airway filter placed
next to the airway adjunct
whats a laryngoscope
used to perform a skill (direct laryngoscopy)
used to achieve optimal visualisation of the glottis for the purpose of oral endotracheal (et) tube insertion/removal of foreign body
what does a laryngoscope consist of
non-disposable handle
battery powered light
dingle use fibre optic blade
what the 2 types of blade
miller (kid-not used as much)
Macintosh (adults-used most common)
for adults- most common size is 3 and 4
what are magil foreceps
magil forceps are long angled forceps that grasp objects lodged in the pharynx.
what 2 objects are used well together
laryngoscope and magil forceps
whats intubation
endotracheal intubation (et) is the introduction of a cuff-sealed tube into the trachea.
what are the different sizes of the et tube
most common adult sizes= 6.7.8
what are boogies
60cm long tracheal tube introducers with an external diameter of 5m to accommodate tracheal tubes.
how do you insert a boogie
thread the over the boogie once it’s been inserted.
whats capnography
measures the amount of carbon dioxide at the end of each breath
can help determine the adequacy and effectiveness of ventilation
the level of co2 normally found in air is small, when person breaths out co2 level rises and measurement is taken.
how to set up a capnography
co2 reader will be plugged into zoll (side of machine)
sampling line can be placed in airway circuit after the catheter mount
will generate a reading
what is a ventilator
helps with patients whose alveolar ventilation is inadequate to maintain normal partial pressures of oxygen and carbon dioxide
can be achieved by mechanical ventilation or manually generated positive pressure.
this would be attached to an et tube/igel .
how many controls are on a ventilator
12
what is tidal volume
is the amount of air that moves in or out of the lungs with each respiratory cycle.
how many ml does average male and female have
500ml for men 400ml for women
how many litres does average bvm hold
approximately 1 litre (which is why we only press half way)
what is cannulation
iv=vein
so iv canulation is the insertion of a plastic tube (catheter)into a peripheral vein.
needle is withdrawn after venepuncture whilst flexible plastic catheter remains in the vascular compartment
iv canulation gains access to the body’s circulation and an iv cannula will be used to deliver either drug/fluid therapy
what are the different sizes of peripheral cannulas
24 guage= smallest
14 guage= largest
yellow(24G) blue (22G) pink(20G) green(18G) grey (16G) orange (14G)
whats a giving set
iv therapy= delivered intrabenously via a bag of fluids where a drug can be added.
the fluids are connected to the pateints vascular access devicee (either intraosseous or intravenous) vis length of plastic tubing.
iv drug= slow rate over long time into circulatory system.
how to set up a giving set
turn the flow controller off (roll down)
insert spiked end of giving set into fluid bag
hang fluid on drip stand
squeeze transparent drip chamber until theres 1.5cm of fluid in the chamber
start the flow by rolling up
run fluid down whole way to check air bubbles
