CPG Need to know Flashcards
When should COPD be expected?
- Any pt over 40 yrs, smoker or ex smoker, experiencing dyspnoea that is worse with exercise, chronic cough or sputum production, family hx of COPD
When might pulse oximetry be unreliable in pts?
Peripheral vascular disease, severe asthma, severe anaemia, cold extremities or peripherally ‘shut down’, severe hypotension and CO poisoning
When is 02 exchange at its greatest?
Upright position
Women >20 weeks pregnant who are hypoxaemic?
Managed with left lateral tilt to improve cardiac output
Face masks should not be used for flow rates..?
< 5 L/min due to the risk of Co2 retention
SP02 85-93% ?
Titrate 02 flow to SP02 94-98%
Nasal cannulae: 2-6L/min
Simple face mask: 5-10L/min
Critical Illnesses (8)
Cardiac Aresst/ resuscitation CO poisoning Anaphylaxis Major trauma/ head injury Shock Severe sepsis Status epilepticus Decompression Illness
Sp02 < 85 %
Non rebreather mask 10-15L/min
(If inadequate consider BVM with 100% 02)
Once pt haemodynamically stable, titrate 02 flow to 94-98%
Chronic hypoxaemia (3)
COPD/ Pulmonary disease
Neuromuscular disorders
Obesity
Chronic Hypoxaemia management
Titrate o2 flow to 88-92 %
If no critical illnesses present: initial dose 2-6L/min
Consider simple face mask: 5-10L/min
If Pt deteriorates or Sp02 < 85%
- BVM ventilation with 100% 02
- Consider LMA
Perfusion definition
The ability of the cardiovascular system to provide tissues with an adequate oxygenation blood supply to meet their functional demands at that time and to effectively remove the associated metabolic waste products

Actual time critical
As the time of VSS, the pt is in actual physiological distress
Emergent time critical
At the time of VSS, the pt is not in physiological distress but does have a pattern of injury or significant medical condition which is known to have a high probability of deteriorating to actual physiological distress
Potential time critical
At the time of VSS, the pt is not physiologically distressed and no pattern of actual injury/ illness , but there is a mechanism of injury knwn to have potential to deteriorate to actual physiological distress
Trauma Triage
Pts meeting criteria for major trauma should be triaged to highest major trauma care within 45 mins, receiving hospital must also be notified
Obstetric trauma pts
All obstetric pts who meet the time critical trauma criteria or any pt who is > 24 wks gestation with any trauma or potential harm to unborn child should be transported to Royal melb hospital within 45 mins. If > 45 mins, transport to nearest alternative highest level of trauma service
A pt under trauma triage guidelines meets the criteria for major trauma if that have a combination of MOI and other co morbidities …:
Systemic illness limiting normal activity/ systemic illness constant threat to life: -Poorly controlled hypertension -Obesity - Controlled or uncontrolled CCF - Symptomatic COPD - Ischaemic heart disease - Chronic renal failure or liver disease Pregnancy Age < 15 or > 55
In the setting of major trauma, an adult is considered time critical if they meet any of the following criteria:
- HR < 60 or > 120
- RR <10 or >30
- SBP < 90
- Sp02 < 90%
- GCS < 13
Specific Injuries meeting potential major trauma criteria:
All penetrating injuries (except isolated superficial limb injuries)
Blunt Injuries
- Serious injury to a single body region such that specialised care or intervention may be required or such that life, limb or long- term quality of life may be at risk
- Significant injuries involving more than one body region
Specific Injuries
- Limb amputation or limb threatening injury
- Suspected spinal cord injury or spinal fracture
- Burns > 20% TBSA or suspected respiratory tract burns
- High voltage burn injury
- Serious crush injury
- Major compound fracture or open dislocation
- Fracture to 2 or more of femur/ tibia/ humerus
- Fractured pelvis
High risk criteria for major trauma:
Assess for mechanism of injury:
