2 results of chest compressions
- Produce CO2 by generalised ^intrathoracic pressure and direct pressure on the heart.
- Release of compressions allows blood flow back to heart
- Early Recognition and Call for Help
- Signs of collapse and impending cardiac arrest
2. 111 in response to chest pain, SOB or sudden collapse
- Early CPR
- ^2-3 times survival rate when CPR began by bystanders
2. Risk of NOT doing CPR on someone who NEEDS it, outweighs the the risk of doing CPR on someone who does NOT.
- Early Defib
- Common cause of CA is VF
2. AED and BLS ^survival

What does a Precordial Thump do?
Mechanical stimulation by producing a myocardial depolarisation to covert VT to SR.
When should Precordial Thump only be used?
Person who is monitored, when a Defib is not immediately available and when the onset of VT is witnessed.
How to do Precordial Thump?
Hold cleaned fist April 25-30cm above the sternum. Bring fist down sharply. Immediately start CPR after.
Where does an Oropharyngeal airway sit?
Tip sits at the back of the pharynx keeping the tongue forward and airway open.
How to measure OPAs?
Distance from persons earlobe to corner of the mouth from the mid-incisor to angle of the jaw.
Size 3,4 for Adults
How to insert OPA?
- Open mouth
- Imager OPA upsidedown
- Once behind the tongue, rotate 180deg to final position.
What is a CE grip?
Place thumbs over top of mask.
Place index fingers over the bottom of the mask.
Provide head tilt-chin lift with middle and ring fingers.
Ensure little finger is behind the angle of the jaw and provide jaw thrust with little finger and seal the mask to face.
How to do alternate CE grip?
Place heels of both hands firmly into the sides of mask.
Place all four fingers behind the angle of the jaw.
Apply very firm jaw thrust with all four fingers to seal the mask to face.
What is an LMA?
Has in inflatable cuff that sits above the vocal cords.
What advantages of LMA?
Opens airway when OPAs are insufficient.
Maintains open airway without ongoing airway manoeuvres.
Insertion while compressions continue.
When ETT is difficult.
Stops aspiration.
How do you insert an LMA?
- Test the cuff - with 30ml syringe.
- Lubricate back of cuff.
- Hold LMA with line facing towards you.
- Hold LMA like a pen and insert directly backwards following the HARD PALATE.
- Press LMA backwards and downwards around the corner until it goes no further.
- Inflate cuff with cuff size x 10.
Does LMA protect against regurgitation?
No.
Aspiration is less common than with ORO or NASO

Managing is getting a NEW view of situation not biased. Second opinion by someone NOT involved and don’t infect them.
Change perspective and step back to look at bigger picture.
- Double check
Correlating what we already know from different sources.
Making sure what you remember you perceived is what you actually perceived.

Not good at multitasking.
ABC sequence.
Don’t get fixated.
- Set dynamic priorities.
Don’t stick to decisions.
After evaluation it may need new priorities and goals.
Ask for other views and opinions.
