When assisting a dentist, an assistant may need to hold the high volume evacuation (HVE) attachment and use it to suction aerosols produced by the dentist's tools, particularly the high speed handpiece or the cavitron. The main objective of suctioning is to hold the inlet of the HVE attachment close enough to the source of aerosols to evacuate those aerosols, while avoiding suctioning of the patient's intra-oral soft tissues, and avoiding contact of the HVE attachment with the handpiece, cavitron or other instrument that the dentist is using. In general, assisting a dentist with suctioning is a somewhat complex skill that may require months of experience before an assistant develops an intuition for suctioning. This is the second part of a two-part article, and focuses on how to position the HVE suction inlet at various locations intra-orally and on how to maintain and clean the dental office suction pipes.
在协助牙医时，助手可能需要手持高速吸引器（HVE）附件，并用其吸除牙医工具产生的气溶胶，特别是高速手机或超声洁牙机产生的气溶胶。吸引的主要目的是将HVE附件的入口靠近气溶胶源以吸除这些气溶胶，同时避免吸住患者口腔内的软组织，并避免HVE附件与手机、超声洁牙机或牙医正在使用的其他器械接触。一般来说，协助牙医进行吸引是一项 somewhat 复杂的技能，助手可能需要数月的经验才能培养出吸引的直觉。本文为系列文章的第二部分，重点介绍如何将HVE吸引入口放置在口腔内的不同位置，以及如何维护和清洁牙科诊所的吸引管道。 （注：原文中“somewhat”未准确翻译出其含义，可根据语境灵活处理，比如“颇为”“有点”等）
