Foreword

YY/T 0735 the general title "Anaesthetic and respiratory equipment respiratory gas humidification body heat and moisture exchanger (HME)", includes the following Section a few.

--- Part 1. For a minimum tidal volume of 250mL of HME;

--- Part 2. minimum tidal volume for tracheotomy surgery patients was 250mL of HME. This section YY/T Section 10735 of. This part identical with ISO 9360-1.2000 "Anaesthetic and respiratory equipment respiratory gas humidification body heat and moisture exchanger (HME) Part 1. The minimum tidal volume for 250mL of the HME. " This section Appendices A and B are informative appendices. This part of the National Standardization Technical Committee on Narcotic breathing apparatus and (SAC/TC116) centralized. This section is drafted. Shandong Medical Devices Product Quality Inspection Center. The main drafters of this section. Wu Ping, Zhang Bo, Song Jinzai, Wan Min. YY/T 0735.1-2009/ISO 9360-1.2000

General medical gases lack of sufficient water, it is difficult to adapt to the physical needs of patients in the respiratory tract. HME to call for improving the delivery Getter track moisture content and temperature. They are primarily expected to be used independently or as part of the respiratory system.

1 Scope

YY/T 0735.1 is Part 1 of the Chinese heat and moisture exchanger standard, covering HMEs used with minimum tidal volumes of 250 mL, that is, the passive humidifiers placed in the breathing circuit of an intubated adult. An HME works by capturing the heat and moisture of each exhaled breath and returning them on the next, and its performance is measured as the moisture output it sustains, together with the flow resistance and dead space it adds. Those three quantities trade against each other, which is why they are specified together. Part 2 covers HMEs for tracheostomised patients. For a manufacturer or an importer of circuit HMEs for the Chinese market, this is the governing product standard.

YY/T 0735 provisions of this part of the tidal volume equal to or greater than 250mL, primarily intended for patient respiratory gas humidification, and to It includes at least one machine port HME (including HME respiratory system with filter) with the relevant requirements, and provides them into Standard Test Method for Evaluation row.
