What is the difference between right and left heart failure?
Definition
Right usually due to COPD, pulmonary embolism - lungs clear, with peripheral edema and jugular venous distension (JVD)

Definition
Monitors heart rhythm and delivers shocks as needed
Term
What heart rhythms need to be defibrillated quickly?
Definition
Ventricular fibrillation or ventricular tachycardia needs to be defibrillated as soon as possible for optimal survivability
Term
How quickly should you use an AED in cardiac arrest?
Definition
CPR should be performed while AED preparation occurs, complete 2 minutes of CPR then follow the AED prompts in a unwitnessed patient, however in a witnessed cardiac arrest go straight to defibrillation
Term
When do you transfer a cardiac arrest patient?
Definition
- when patient regains pulse
- after delivering 3 shocks
- after receiving one “no shock advised” message
(finish packing patient during following 2 minutes of CPR)
stop ambulance to use AED because it interferes with the monitor
Term
What is the difference between hemiparesis and hemiplegia?
Definition
Hemiparesis means weakness and hemiplegia means paralysis down one side of the body - most commonly caused by a stroke (cerebrovascular accident CVA -blockage of blood supply to one side of brain)
It can be congenital due to birth damage
Term
What do 1. aura and 2. post-ictal mean?
Definition
1. an aura is hallucination of smell, taste, hearing, sight, touch
that may warn of an impending seizure
2. post-ictal is a sleepy, lethargic state after a seizure
Term
Name three different types of seizure disorder.
Definition
- grand mal / tonic-clonic
- petit mal / absence
- Jacksonian / focal motor
(- postictal state and status epilepticus)
Term
What are the signs of haemorrhagic stroke or ruptured aneurysm?
Definition
Hallmark - sudden severe headache (as if hit on head)
Other - changes in sensations (vision/ hearing/ taste/ smell/ feeling), unequal pupils, coordination/ balance changes, facial droop/unequal smile, drooling, memory disturbances…long or short term, behavioral disturbances, incontinence
Term
Which has higher mortality - ischemic or haemorrhagic strokes?
Definition
Haemorrahgic.
Term
How do you tell the difference between ischemic and haemorrhagic stroke?
Definition
Ischemic Stroke (1) vs Hemorrhagic Stroke (2)
- (1) more common
- cause: (1) atherosclerosis or tumor (2) cerebral aneurysms, arteriovenous (AV) malformations, hypertension
- onset: (1) slow (2) abrupt
- (1) long history of vessel disease (2) stress or exertion
- (1) valvular heart disease and atrial fibrillation (2) cocaine and other sympathomimetics
- (1) previous angina or strokes (2) aneurysm may be asymptomatic before rupture
Term
What are the signs of a TIA (transient ischemic attack)?
Definition
Hallmark: sudden severe head-ache, hemiparesis and hemiplegia, goes away within 24 hours
Other: denial, changes in sensations (vision/ hearing/ taste/ smell/ feeling), pupils unequal, coordination/ balance changes, facial droop/ unequal smile, drooling, memory disturbances…long or short term, behavioral disturbances, incontinence, altered LOC
Term
What else do you consider in a patient with a suspected stroke?
Definition
- hypoglycemia
- postictal state
- drug/ alcohol use
- subdural or epidural bleeding (head trauma)
- traumatic brain injury (TBI)
Always consider other problems when dealing with a suspected stroke
Term
What is Cushing's triad and what does it tell you might be happening?
Definition
Associated with raised intracranial pressure
1. hypertension, a blood pressure that is increasing from normal, often over 180 systolic and with relatively low diastolic
2. bradycardia, pulse rate decreasing from normal, often <60
3. Cheyne-Stokes breathing (deep/ irregular breathing pattern)
Term
What do you do if you suspect raised intracranial pressure (ICP)?
Definition
If signs of ICP/Cushing’s triad present (unconscious, irregular
breathing, slowing down of the pulse and unequal pupils) hyper-oxygenate using a BVM with a O2 flow rate of 15 L/min making sure reservoir bag is never less than 2/3 full ventilating 1 breath every 3 seconds or 20/min. Elevate head of stretcher/ back-board by 15-20 degrees
Term
Do you give acetylsaliclylic acid (ASA) to stroke patients to treat a clot?
Definition
No, never - because it may well be haemorrhagic so you would make it worse.
Term
How quickly does proper treatment have to start in a case of stroke?
Definition
Treatment needs to start within 3 to 6 hours of onset, pending protocols
Term
What are the acronyms (letters in code form) for neurological assessment?
Definition
AEIOU
A Alcohol, Apnea, Anaphylaxis
E Epilepsy, Environmental
I Insulin
O Overdose
U Underdose
TIPS
T Trauma
I Infection
P Psychiatric, Poisoning
S Stroke, Shock
Term
What are the three physical findings in the Cincinnati Stroke Scale?
Definition
1 facial droop
2 arm drift
3 speech
Term
What are the signs of a grand mal, generalized tonic-clonic seizure?
Definition
Hallmark: unconscious patient, severe, jerky muscle twitching and clenching
Other: cyanosis, abnormal or noisy breathing, absence of respirations, possible head injury, loss of bowel and bladder control, severe muscle twitching, post seizure state of unresponsiveness with deep and
labored respirations
Term
What are the signs of petit mal/ absence seizure?
Definition
Hallmark: staring episodes, sudden halt in conscious activity
Other: no movement, hand fumbling, fluttering eyelids, lip smacking, chewing, lack of awareness of surroundings, may be provoked by hyperventilation or flashing lights, in some cases, abrupt beginning of seizure, each seizure lasts no more than a few seconds, full recovery of consciousness, no confusion, no memory of seizure
May occur hundreds of times a day
Term
What are the signs of a Jacksonian/ focal motor seizure?
Definition
Hallmark: one limb or portion of limb shaking uncontrollably (e.g. hand)
Other: memory impairment, usually fully conscious, may spread to a generalized seizure so transport required
Term
What is the usual progression of a seizure?
Definition
Aura - happens to some, usually
30 seconds to 2 minutes beforehand, varies between patients, smelling or tasting something odd like burnt toast is common
Seizure - uncontrolled electrical activity in brain causes convulsion
Postictal State: period after convulsions patient is physically exhausted, may have a decreased LOC, may last a few seconds to many hours
Term
What is status epilepticus?
Definition
Any seizure activity that lasts more than 5 minutes without return of consciousness, repetitive seizure activity with no regaining of consciousness

Term
What is Sellick's manoeuvre?
Definition
Cricoid pressure
Use on unconscious patients to prevent passive regurgitation (EMT’s and Paramedics)
EMRs should ensure the airway is open and ventilate over 1-2 seconds to prevent gastric distention
