Cardiac Arrest Flashcards
When do you call a cardiac arrest
Pt not breathing
No cardiac output - CO not sustaining life
Trauma order vs medical
A/ haemorrhage control - CT6 - PELVIC BINDER - TORNIQUET - C-SPINE
B C D
Tension - as a part of 4H4T this may come early - in C or B as an early consideration - Bilateral
Adrenaline in arrest
When to give
Dose
How to draw up
Hypothermia
30-35
<30
In witnessed arrest give immediately. In others, every 4 minutes (second loop) in all arrests.
1mg every second loop
First is neat 1mg neat- subsequent can be stacked in syringe
30-35 every 8 minutes - 4th loop
<30 - no drugs
Compression ratio
When does it change
30: 2 with a OPA or Naso - Pause for breaths
15: 1 with Igel or Intubation continuous
How do compressions and ventilations change in resp arrest - eg asthma
Hands off completely on inspirations - slow ventilations to avoid gastric inflation if possible.
Bag off during compressions to enable full exhalation.
Ventilation intervals may be lengthened.
HATS
Haemorrhage
Airway control
Tension
Saline
Position for pregnant people in arrest
15-30 degree tilt - left lateral to reduce compression of inferior vena cava
Transport under Arrest
Transport specifics
Roles assigned
25km/hr to maintain effective compressions
2 people
Transport under Arrest
Patient criteria
Witnessed arrest with compressions commenced within 10 mins
Independent living before arrest
Initial rhythm of VT or VF
Intermittent signs of or unsustained ROSC
CARDIAC ARREST
ECC
- Rate depth interruptions
- rations- with basic and advanced array
100-120 per minute
1/3 chest depth / 5cm and allow full recoil
Minimal interruptions to compressions
30:2 with pause, 15:1 no pause
4H 4T
Hyper/hypo kalaemia - other metabolic
Hypovolaemia
Hyper/hypo thermia
Hypoxia
Thrombus
Tension
Toxins
Tamponade
