Q

what is airway

A

checking for breathing. there are two options - a head tilt chin lift, or a jaw thrust. remove any liquids or foodstuffs with a finger sweep - do not do this blind. this is to prevent any obstruction to the airway

Q

what is breathing and circulation

A

palpate a carotid pulse. look, listen and feel for breathing for 10 seconds. look for any other signs of life

Q

what is agonal breathing

A

this is when the brain becomes hypoxic due to lack of oxygen. it sounds like infrequent gasps and gulping. this is not normal, and should not be counted as breathing. can also be accompanied with seizure like movements

17
Q

when do you start doing chest compressions

A

immediately

18
Q

what do you say on the phone to 999 if you think someone has gone into cardiac arrest

A
  • there is a cardiac arrest
  • there is no breathing
  • location
  • contact number
  • covid status of the person
19
Q

what should be worn when doing cpr

A

droplet ppe

20
Q

how do you do chest compressions

A
  • interlock the fingers
  • straight elbows
  • compress the sternum 5-6cms
  • 2 a second
  • swap with someone else to rest
  • continue until help arrives
21
Q

how to prepare the patient for AED

A
  • remove clothing- there will be scissors to cut through
  • dry any fluids off chest with whatever fabric there is
  • shave hair off the areas where the pads will be placed
  • attach the pads to the patient and listen for voice prompts
  • early defibrillation is key intervention with improved neurological outcomes
  • aim to defibrillate within 3 minutes of the cardaic arrest to have the highest survival rate for the patient
22
Q

how many joules are there per shock from AED

A

150-360

23
Q

what is essential regarding AED

A

that no one is touching the patient when the shock is administered

24
Q

how do you ventilate the patient

A
  • this is a 2 person technique
  • ensure an adequate seal
  • use cylinder alongside a bag valve mask
25
Q

how much oxygen do you administer during ventilation

A

15 litres of 100% oxygen per minute

26
Q

what are the features of an oxygen cylinder

A
  • cylinder gauge
  • oxygen litre titration
  • tubing port
27
Q

how many litres of oxygen does the bag on the bag valve mask hold

A

2

28
Q

what are the features of a bag valve mask

A

oxygen reservoir
self filling bag
delivery valve
mask
oxygen inlet

29
Q

what are HMEs and what do they do

A

these are humidity moisture exchange filters and are there to protect you from any aerosols

30
Q

how does basic life support change if someone has covid

A
  • you cover the nose and mouth of the patient with whatever there is to hand
  • wear complete ppe
  • do not go near the airway unless in full ppe
  • to stay clear of the airway whilst still checking for breathing, press hand on the chest and palpate for carotid pulse for 10 seconds to check for life. can assess breathing visually
31
Q

where are the defibrillators in the dental hospital

A

on level 1, 3, 4, 6, 7

32
Q

where is the defib on level 1

A

surgery 1

33
Q

where is the defib on level 3

A

mops

34
Q

where is the defib on level 4

A

recovery

35
Q

where is the defib on level 6

A

clean room A/B

36
Q

where is the defib on level 7

A

clinic D

37
Q

what is involved in post resuscitation care

A

reassessment of breathing and circulation
reassure the casualty even if they are unconscious. do not tell them they died and came back.
maintain the airway, deliver oxygen via the bag valve mask unless they are uncomfortable with the aid
do not remove the AED pads, cover them up to provide dignity and warmth
be prepared to administer further cpr if there is rearrest
keep all the emergency equipment to hand

38
Q

what are the features of a non rebreathing trauma oxygen mask

A
  • expiration and inspiration valves
  • oxygen feeding line
  • oronasal face mask
  • oxygen reservoir bag
39
Q

what are oropharygneal airway adjuncts

A

medical devices used to maintain the patient’s airway

40
Q

how can a dental practice be ventilated

A

extractor fans and open windows
