Mechanical Circulatory Support – A Practical Approach
Mechanical Circulatory Support
Magill forceps
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 and blades
Laryngoscope - device used to visualise the vocal cords to facilitate intubation
Jugular Bulb Oxygen Saturation
Jugular Bulb Oxygen Saturation = measure of oxygen delivery and extraction to the brain; assess information about cerebral metabolism and blood flow
IVC Filter
IVC Filter filter placed in the inferior vena cava (IVC) to prevent clot passage; first introduced in the 1960s
Intraosseous access
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
CICM SAQ 2015.2 Q19
Question a) Interpret the three pharmacodynamic (PD) profiles, labelled Scenario 1, Scenario 2 and Scenario 3, shown below. b) For each PD profile, describe how you would optimise the dose and/or frequency of antibiotic if prescribing: i) a beta lactam…
Intra-Abdominal Pressure Monitor
Intra-Abdominal Pressure Monitor: device used to assess intra-abdominal pressure (IAP) - the steady state pressure concealed within the abdominal cavity
Intermittent Pneumatic Compression device
Intermittent Pneumatic Compression device; aka sequential compression devices; prevent lower limb DVTs in immobile patients
Humidification
With normal nasal breathing the temperature in the upper trachea is between 30°C and 33°C, with a relative humidity of approximately 98%, providing a water content of 33 mg/L
Heat and Moisture Exchanger
Heat and Moisture Exchanger (HME); those in current use are generally combined with a microbiological filter, hence they are called HME filters (HMEF)
