Funtabulously Frivolous Friday Five 129
Funtabulously Frivolous Friday Five 129 - Just when you thought your brain could unwind on a Friday, some medical trivia FFFF.

Cuff Pressure Gauge
Cuff pressure gauge aka cuff manometer; allows safe inflation of the cuff seal of low pressure endotracheal and laryngeal tube cuffs by measuring the cuff pressure
Wet Circuit / Humidifier
OVERVIEW A “wet circuit” is a breathing circuit with active humidification, as opposed to a “dry circuit” that uses a Heat and Moisture Exchanger (HME) USES DESCRIPTION METHOD OF INSERTION AND/OR USE Pitfalls COMPLICATIONS PROS AND CONS Advantages Disadvantages References…
Transcranial Doppler (TCD) Ultrasound
Transcranial Doppler (TCD) is a non-invasive technique for monitoring blood flow velocity (FV) in the basal cerebral arteries using Doppler ultrasound
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
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
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)
