Theatre staff's knowledge of surgical face masks
Abstract:
Surgical face masks have been worn for over a century. Their initial implementation was to reduce wound infection by reducing droplet spread from the surgical team's mouth and nose. More recently face masks have been worn to protect the surgical team from contamination from patients and hazards within the operating theatre. To facilitate this, a range of face masks is available. The commonest are the standard face mask with a filtration ability of approximately 5 microns, and the LASER face mask with a filtration ability of 1.1 microns. The purpose of this study was to determine staff's knowledge of face masks.

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment

PPE Use in Healthcare Settings I: Donning
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,...
