Auscultate both axillae and the stomach
What is the most concerning complication of intubation?
Accidental oesophageal intubation
What are the causes of a gradual fall in expired CO2 in a ventilated patient?
Cardiac arrest
Inadequate chest compressions
Pulmonary embolism
What are the causes of a a sudden drop in expired CO2 in a ventilated patient?
Disconnection of breathing system
Extubation
Ventilator Failure
What is appropriate dose for IV morphine?
0.1mg/kg bolus
Wait 10 minutes
Then titrate upwards
Define situational awareness
The cognitive process for building and maintains awareness of a workplace situation or event
What are the pre-terminal signs of hypoxia?
Bradycardia
Cyanosis
Drowsiness
What are the causes of a bounding pulse ?
Increased cardiac output (e.g. septicaemia)
Arterio-Venous systemic shunt (e.g. PDA)
Hypercapnia
What should be your initial fluid resuscitation?
10ml/ kg of crystalloid
How do you treat DKA?
Treat shock (if present) with 10ml/kg fluid bolus
Rehydration fluid > 48 hours
Insulin infusion 0.05-0.1 unit/kg/hour 1-2 hours AFTER initiating rehydration and maintenance fluid
Glucose infusion once BM <14
In DKA what does sodium do? And what does it do after treatment?
It’s low
Goes up as glucose goes down
What are feature of cardiac cause for breathing difficulties?

Tachycardia out of proportion with respiratory symptoms
Raised JVP
Gallop rythm
Enlarged liver
Absent femoral pulses.
What causes cardio genie shock?

What is clinical picture for toxic shock syndrome?
Fever. Diffuse erythema. Headache, confusion, conjunctival and mucosal hyperaemia, vomiting, water diarrhoea +- history of infected wound/ burn/ surgery/ deep seated infection
What is management of toxic shock syndrome
IV fluclox and vancomycin!
What are the causes of yacht arrhythmias?
Metabolic disturbance
Long QT
cardiomyopathy
Poisoning
Re-entrant congenital conduction pathway abnormality
How to treat SVT in context of no clinical shock
Bagel manoeuvre
