Skills & Behaviours
Obtain blood gas samples using aseptic techniques; interpret data from arterial, central venous or mixed venous samples
Identify deviations from normal range and interpret these in the context of the clinical circumstances
Interpret chest x-rays in a variety of clinical contexts
Professional and reassuring approach - generates confidence and trust in patients and their relatives
Examine patients, elicit and interpret clinical signs (or relevant absence of clinical signs) in the ICU environment
Differentiate real change from artefact & respond appropriately
Obtain relevant information from the patient, relatives and other secondary sources
Communicate effectively with radiological colleagues to plan, perform and interpret test results
Listen effectively
Obtain blood cultures using aseptic techniques
Acquire, interpret, synthesize, record, and communicate (written and verbal) clinical information
Develop a working, and limited differential diagnosis based on presenting clinical features
In emergency situations, confirm or refute early diagnoses before data collection / analysis is complete - make contingency plans based on these diagnoses to combat further threats to the patient's life
Integrate clinical findings with results of investigations
Recognise impending organ system dysfunction
Communicate and collaborate effectively with all laboratory staff
Integrate history with clinical examination to create a diagnostic and therapeutic plan
Order and prioritise appropriate investigations
Assemble clinical and laboratory data, logically compare all potential solutions to the patient's problems, prioritise them and establish a clinical management plan
Evaluate benefits and risks related to specific investigations
Interpret laboratory results in the context of the patient's condition
Confirm adequate oxygenation and control of PaCO2 and pH
Identify abnormalities requiring urgent intervention
Monitor vital physiological functions as indicated
Recognise significant changes and the need for repeated testing (ie. that a single normal result is not as significant as identifying trends of change by repeated testing where indicated)
Obtain and accurately record data from monitors
Document investigations undertaken, results and action taken
Undertake further consultation / investigation when indicated
Set and interpret data from ventilator alarms
