Peripheral Intravenous Cannula (PIVC) aka venflon: Uses; IV fluid administration; blood sampling; drug administration; needle thoracostomy for tension pneumothorax; needle cricothyroidotomy

Non-rebreathing (NRB) Oxygen Mask; delivery of high FiO2 in the spontaneously breathing patient

Oropharyngeal Airway (OPA): Lifts the tongue off the posterior pharyngeal wall to prevent airway obstruction; bite block; assist oropharyngeal suctioning; promotes moulding of the face of a mask for manual ventilation

non-invasive blood pressure measurement involves the application of a pressure cuff and can be performed manually (listening for Korotkoff sounds as the pressure is released

Mechanical Circulatory Support

Magill forceps: aid passage of an endotracheal tube into the larynx (e.g. nasal intubation); aid gastric tube passage into the oesophagus; remove foreign bodies from the airway/ pharynx; place pharyngeal packs (e.g. bleeding)

Laryngoscope - device used to visualise the vocal cords to facilitate intubation

Jugular Bulb Oxygen Saturation = measure of oxygen delivery and extraction to the brain; assess information about cerebral metabolism and blood flow

IVC Filter filter placed in the inferior vena cava (IVC) to prevent clot passage; first introduced in the 1960s

Intraosseous (IO) access can be obtained using manual or drill-inserted devices for insertion of specialised needles; IO access uses the medullary space as a non collapsible entry point into the systemic venous system


Intra-Abdominal Pressure Monitor: device used to assess intra-abdominal pressure (IAP) - the steady state pressure concealed within the abdominal cavity
