A Refashioned Head Cover Device of Personal Protective Equipment to Facilitate Conventional Auscultation

Indian Pediatrics
Conventional stethoscope is a useful clinical examination tool to aid evaluation of the underlying clinical condition, especially respiratory and cardiac illnesses, even before definitive imaging studies are performed. Auscultation with a stethoscope becomes highly challenging when wearing personal protective equipment (PPE) because the hood of the PPE

An investigation into the effect of protective devices on the dose to radiosensitive organs in the head and neck

The British Journal of Radiology, 1992
Abstract A series of experiments were performed to determine the dose reduction afforded to radiosensitive organs in the head and neck by various protective devices. These included spectacles with plastic, standard glass, photochromic and lead-glass lenses, a thyroid collar and a lead-acrylic face mask.
