Q

COPD patho

A

Group of respiratory disorders characterised by increased mucous production and secretion, airway inflammation and reduced lung elasticity. Irreversible and progressive.

Chronic bronchitis - obstructed airflow due to increased mucous production/secretion and inflamed bronchioles due to exposure to irritants.

Emphysema - permanent enlargement of the airways and damaged alveolar walls due to toxins inhaled, reduced area for gas exchange.

Q

APO patho

A

When the left ventricular muscle weakens or fails, there’s a reduction in cardiac output. Causes back flow into the pulmonary arteries and capillaries. Due to the pressure difference, fluid moves into the pulmonary interstitial space and the alveolar.

22
Q

ACS treatment (STEMI)

A

Aspirin, if inferior STEMI BP <160mmHg then no GTN. Defib pads on immediately and notify hospital.

23
Q

cardiac arrest patho

A

Heart is not in a normal sinus rhythm

24
Q

cardiac arrest signs/symptoms

A

No response, unconscious, no breathing, no pulse

25
Q

cardiac arrest treatment

A

High performance CPR, adrenaline administration 1mg (1mL) every 2 minutes

26
Q

stroke patho

A

When a part/parts of the brain isn’t receiving adequate blood supply and oxygen, due to a clot or haemorrhage, causing focal injury of the brain

27
Q

TIA

A

Momentary blood flow obstruction causing a brief episode of neurological dysfunction. Usually only lasts 1-24 hours, no damage caused.

28
Q

stroke signs/syptoms

A

Facial droop, low GCS, severe headache, nausea vomiting, slurred speech, motor deficits.
ICH - more likely to have severe headache, nausea and vomiting, quick fall in GCS, bradycardia
Left side - slow mobility
Right side - perceptual disturbances

29
Q

Stroke mimics

A
S - syncope
S - sepsis
S - subdural haematoma 
S - seizures
H - hypoxia
I - intoxication
I - inner ear disturbance
T - tumour (brain)
M - migraine
M - multiple sclerosis 
E - electrolyte disturbance
30
Q

stroke/TIA treatment

A

Suspected stroke or TIA should always be transported. Oxygen therapy if SpO2 <92%.
ICH suspected: if awake/responding transport to nearest stroke hospital, if unconscious then nearest neurosurgical centre

MASS +, ACT-FAST - , >12 hours = non urgent transport
MASS +, ACT-FAST -, <12 hours = Non ECR eligible stroke. IV access, pre-notify hospital
MASS +, ACT-FAST + = possible ECR eligible stroke. IV access, pre-notify hospital, urgent.

31
Q

seizures patho

A

Sudden uncontrolled episodes of electrical activity in the brain. Neurons rapidly fire, and depending on where in the brain, can cause movements, sensations, altered consciousness etc.

32
Q

seizure types

A

Focal: starts in one part of the brain, may spread

  • simple partial (aware)
  • complex partial (unaware)

Generalised: both sides or the brain simultaneously

  • absence (disconnected)
  • clonic tonic (sudden jerking)
  • myoclonic (twitch jerk)
  • tonic (limp)
33
Q

seizure signs/symptoms

A

Altered conscious state, convulses

34
Q

seizures treatment

A

Oxygen and ventilations (OPA or NPA if trismus)
