Principles of Resuscitation Flashcards
what is resuscitation?
process of correcting physiological disorders in an acutely unwell patient
describe the pathophysiology of cardiac arrest?
adequate airway, breathing and circulation needed for oxygen delivery to organs > inadequate oxygen delivery > organ failure > cardio-respiratory arrest
what are some clinical indicators of deterioration before cardiac arrest?
tachypnoea tachycardia hypotension reduced conscious level use trends in clinical observations (NEWS)
how do you rapidly assess acute illness?
ABCDE
important things to consider if patient becomes acutely unwell?
best place/position
equipment needed
help from others
who are you going to call? (ghostbusters)
how do you asses airway?
is it open or closed? obstruction? blood? action required? adjuncts? do you need anaesthetic support?
how can you support an airway?
nasopharangeal oropharyngeal chin lift iGels Laryngeal mask airway
how do you assess breathing?
breathing present or absent adequate ventilation? establish oxygen source and means of delivering oxygen oxygen sats visual signs - cyanosis, pursed lips etc
general rule for oxygen delivery?
all patients get high flow oxygen
- if emergency just give it even if you don’t know whether they have COPD
what is hypoxic drive?
central chemoreceptors which usually stimulate breathing when they sense high CO2 levels are down regulated due to chronically high CO2 in COPD patients
they therefore rely on peripheral chemoreceptors which stimulate breathing when they sense low oxygen - therefore by giving high flow oxygen these peripheral chemoreceptors dont sense any low oxygen so dont stimulate breathing
how is oxygen delivery managed in COPD patients?
unless someone is a known CO2 retainer then give all breathless patients oxygen
then measure ABGs
- if CO2 fine then monitor
- if CO2 rising then aim O2 sats at 88-92%
what can the high CO2 in the acutely unwell patient be confused with?
pulmonary oedema
differentiate by looking at HCO3
sepsis 6?
blood cultures urine output fluids antibiotics lactate oxygen BUFALO
how do you assess circulation?
present or absent ?
- pulse, BP, CRT, ECG
adequate perfusion
- colour, conscious level
what can cause circulatory failure?
internal bleeding/GI haemorrhage
clots - PE, MI, tamponade etc
hypovolaemia (from blood loss)
