23
Q

What must the myocardium be able to do for TCP to be succesful?

A

Myocardium must be able to generate cardiac output with the muscular contractions

24
Q

What are the two types of TCP and which does QAS use?

A

Demand and non-demand/asynchronous

25
Q

How does demand pacing work?

A

Demand pacing senses the inherent QRS complex delivering electrical stimuli only when needed.

26
Q

What are the indications for TCP?

A

Symptomatic bradycardia

27
Q

What are the 2 contraindications for TCP?

A

Asystole/PEA
Overdrive pacing of dysrhythmia

28
Q

What are the 4 complications of TCP?

A

Pain
Discomfort
Anxiety
Failure to achieve electrical capture

29
Q

What position should pads be for TCP?

A

anterior-posterior position

30
Q

What is the correct lcoation of the pads in anterior-posterior position?

A

Anterior pad - At the level of the bottom third of sternum between 4th and 5th ICS
Posterior pad - Left side of back beneath scapula and beside vertebral column

31
Q

What is the most common error in TCP?

A

Not advancing the current high enough to achieve electrical capture

32
Q

What current intensity should be used for conscious bs unconscious patients?

A

Conscious - start at 0 and increase until electrical and mechanical capture occur
Unconscious - Increased current to maximum and advance downwards

33
Q

What are common causes of failure of TCP to improve cardiac output despite electrical capture?

A

hypoxia
acidosis
hypovolaemia

34
Q

What is the phrenic nerve?

A

Phrenic most importantly innovates and has complete motor control of the diaphragm and sensation to the central tendon aspect of the diaphragm.

35
Q

What nerve can be cut when doing a finger thoracostomy and what would that result in?

A

Long thoracic nerve which would result in winged scapulas

36
Q

What needle decompression device is used for what ages/weight groups?

A

> 50kg = Pneumodart
15-50kg (4-14yo) = 14g cannula

37
Q

What length is a pneumodart, 14g cannula, and 16g cannula?

A

14g = 45mm
16g = 30mm

Q

What is the correct position for anterior/lateral pad placement?

A

Anterior pad to the right of sternum below the clavicle

Q

What is the correct position for anterior/lateral pad placement?

A

Anterior pad goes to left of sternum just below left nipple line (underneath breast tissue in females)

44
Q

What is the stepwise approach to airway management in cardiac arrest?

A

Basic airway manoeuvres first followed by iGel if mouth is clear of vomitus or secretions.
