WEEK9- Assisting the paramedic

Question 1

what is an airway filter

Answer 1

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

Question 2

what does hme stand for

Answer 2

heat and moisture exchanger

Question 3

where is the airway filter placed

Answer 3

next to the airway adjunct

Question 4

whats a laryngoscope

Answer 4

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

Question 5

what does a laryngoscope consist of

Answer 5

non-disposable handle
battery powered light
dingle use fibre optic blade

Question 6

what the 2 types of blade

Answer 6

miller (kid-not used as much)
Macintosh (adults-used most common)

for adults- most common size is 3 and 4

Question 7

what are magil foreceps

Answer 7

magil forceps are long angled forceps that grasp objects lodged in the pharynx.

Question 8

what 2 objects are used well together

Answer 8

laryngoscope and magil forceps

Question 9

whats intubation

Answer 9

endotracheal intubation (et) is the introduction of a cuff-sealed tube into the trachea.

Question 10

what are the different sizes of the et tube

Answer 10

most common adult sizes= 6.7.8

Question 11

what are boogies

Answer 11

60cm long tracheal tube introducers with an external diameter of 5m to accommodate tracheal tubes.

Question 12

how do you insert a boogie

Answer 12

thread the over the boogie once it’s been inserted.

Question 13

whats capnography

Answer 13

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.

Question 14

how to set up a capnography

Answer 14

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

Question 15

what is a ventilator

Answer 15

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 .

Question 16

how many controls are on a ventilator

Answer 16

12

Question 17

what is tidal volume

Answer 17

is the amount of air that moves in or out of the lungs with each respiratory cycle.

Question 18

how many ml does average male and female have

Answer 18

500ml for men 400ml for women

Question 19

how many litres does average bvm hold

Answer 19

approximately 1 litre (which is why we only press half way)

Question 20

what is cannulation

Answer 20

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

Question 21

what are the different sizes of peripheral cannulas

Answer 21

24 guage= smallest
14 guage= largest
yellow(24G) blue (22G) pink(20G) green(18G) grey (16G) orange (14G)

Question 22

whats a giving set

Answer 22

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.

Question 23

how to set up a giving set

Answer 23

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

Question 24

how to set up a giving set

Answer 24

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
