Tympanic membrane injury in welders: is prevention neglected?
1Royal National Throat, Nose and Ear Hospital, London, UK.
Abstract:
Injury to the ear in welders is a recognized but poorly documented entity. Five cases are described to demonstrate a spectrum of severity of injury, ranging from minor burns to tympanic membrane perforation requiring myringoplasty. Welders are most at risk when working overhead, in cramped conditions or adjacent to other welders. Conventional safety helmets offer inadequate protection to the ears and it is recommended that insert ear plugs should be offered to all workers at risk, in addition to safer working practices. An increased awareness of these risks among occupational physicians, welders and employers is required before these recommendations can realistically be implemented.

Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.

Pneumothorax-II
Clinical Manifestations:
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
