ISO/TC 150/SC 2/WG 4 - Blood gas exchangers

This document covers the activities performed by perfusionists before, during, and after extracorporeal circulation. Clause 4 covers the perfusionists' actions during preoperative extracorporeal circulation (ECC) equipment setup prior to cardiopulmonary bypass (CPB), extracorporeal membrane oxygenation (ECMO), cardiopulmonary support (CPS), left or right heart bypass (LHB/RHB) or venovenous (VV) extracorporeal support for liver transplantation. Its requirements can serve as a checklist for verifying that the equipment, devices or systems have been set up correctly. The sequence of use of checklist items listed below can vary depending on customary institutional use or individual user preference. There are also four additional checklists for different phases of ECC (see Clause 5, Termination; Clause 6, Post-extracorporeal circulation; Clause 7, Emergent reinstitution of extracorporeal circulation; and Clause 8, Peri-procedural).

ISO 7199:2016 specifies requirements for sterile, single-use, extracorporeal blood-gas exchangers (oxygenators) intended for supply of oxygen to, and removal of carbon dioxide from, the blood of humans. ISO 7199:2016 also applies to heat exchangers and arterial filters that are integral parts of the oxygenator. ISO 7199:2016 also applies to external equipment unique to the use of the oxygenator. ISO 7199:2016 does not apply to - implanted oxygenators, - liquid oxygenators, - extracorporeal circuits (blood tubing), - separate heat exchangers, - separate ancillary devices, and - separate arterial line filter.

ISO 15676:2016 specifies requirements for single-use tubing packs for cardiopulmonary bypass and extracorporeal membrane oxygenation (ECMO). This document is applicable to all medical tubing intended for cardiopulmonary bypass (CPB) and/or extracorporeal membrane oxygenation (ECMO), but specific requirements and tests are included for tubing intended for use with peristaltic pumps during (short-term, i.e. 24 h) ECMO procedures. The sterility and non-pyrogenicity provisions of this document are applicable to tubing packs labelled as "sterile". It is applicable only to the tubing aspects for multifunctional systems that may have integral components such as blood gas exchangers (oxygenators), reservoirs, blood filters, defoamers, blood pumps, etc.

ISO 15674:2016 specifies requirements for sterile, single-use, extracorporeal hard-shell cardiotomy/venous reservoir systems and soft venous reservoir bags intended for use as a blood reservoir during cardiopulmonary bypass (CPB) surgery. It applies only to the blood reservoir aspects for multifunctional systems which can have integral parts such as blood-gas exchangers (oxygenators), blood filters, defoamers, blood pumps, etc.

ISO 15675:2016 specifies requirements for sterile, single-use, arterial blood line filters intended to filter and remove emboli, debris, blood clots and other potentially hazardous solid and gaseous material from the blood of humans during cardiopulmonary bypass surgery.

This International Standard specifies requirements for the physical, biological and performance testing of biocompatible modifications on extracorporeal devices. This International Standard is applicable to components of heart-lung bypass equipment and of extracorporeal life support equipment that carry blood and have modifications on the blood and tissue-contacting surfaces of the device. The assumption is that these devices will be used at conventional ranges of hypothermia and normothermia. If hyperthermia (>37 °C) applications are indicated, then testing is performed over the indicated range.

ISO 15675:2009 specifies requirements for sterile, single-use, arterial blood line filters intended to filter and remove emboli, debris, blood clots and other potentially hazardous solid and gaseous material from the blood of humans during cardiopulmonary bypass surgery.

ISO 7199:2009 specifies requirements for sterile, single-use, extracorporeal blood-gas exchangers (oxygenators) intended for supply of oxygen to, and removal of carbon dioxide from, the blood of humans. ISO 7199:2009 also applies to heat exchangers that are integral parts of oxygenators and to external equipment unique to the use of the device.

ISO 15676:2005 specifies requirements for single-use tubing packs for cardiopulmonary bypass and extracorporeal membrane oxygenation (ECMO). ISO 15676:2005 is applicable to all medical tubing intended for cardiopulmonary bypass (CPB) and/or extracorporeal membrane oxygenation (ECMO), but specific requirements and tests are included for tubing intended for use with peristaltic pumps during (short-term, i.e. 24 h) ECMO procedures. The sterility and non-pyrogenicity provisions of ISO 15676:2005 are applicable to tubing packs labelled as "sterile". ISO 15676:2005 is applicable only to the tubing aspects for multifunctional systems that may have integral components such as blood gas exchangers (oxygenators), reservoirs, blood filters, defoamers, blood pumps, etc.

Requirements for sterile, single-use, extracorporeale blood-gas exchangers (oxygenators) intended for supply of oxygen to, and removal of carbon dioxide from, the blood of humans.
