How Dust Collectors Work During Mixing Powders
Here's how dust collectors work during mixing powders: Capture of Dust: Hood or Enclosure: Mixing processes often take place within an enclosure or hood designed to contain the powders. This helps in localizing the dust generation. Dust Source Collection: The dust collector is strategically placed near the source of dust …
Aspiration under anaesthesia: risk assessment and decision …
Pulmonary aspiration complicates between 1 in 900 to 1 in 10 000 general anaesthetics,1 dependent on risk factors. All novice anaesthetists in the UK are taught to consider the risk of aspiration and to modify their anaesthetic technique accordingly. The prevention of aspiration remains a cornerstone of anaesthetic practice.
