Medicinska električna oprema - 2-4. del: Posebne zahteve za osnovno varnost in bistvene lastnosti srčnih defibrilatorjev - Dopolnilo A1 (IEC 60601-2-4:2010/A1:2018)

Ta mednarodni standard velja za OSNOVNO VARNOST in BISTVENE LASTNOSTI SRČNIH DEFIBLIRATORJEV, v nadaljevanju ME OPREME. Če bo točka ali podtočka izrecno namenjena samo uporabi za ME OPREMO ali samo za ME SISTEME, bosta naslov in vsebina te točke ali podtočke to tudi navedla. Sicer točka in podtočka veljata za ustrezno ME OPREMO in ME SISTEME. NEVARNOSTI, ki so del fiziološkega delovanja ME OPREME ali ME SISTEMOV v okviru uporabe tega standarda, niso zajete s posebnimi zahtevami tega standarda, razen v točkah 7.2.13 in 8.4.1 splošnega standarda. Ta določeni standard ne velja za vsajene defibrilatorje, DEFIBLIRATORJE z daljinskim upravljanjem, zunanje transkutane srčne spodbujevalnike ali ločene samostojne srčne monitorje (ki so standardizirani z IEC 60601-2-27). Srčni monitorji, ki uporabljajo ločene elektrode ECG za spremljanje, niso v okviru uporabe tega standarda, razen če se uporabljajo izključno za zaznavo prepoznave ritma AED ali zaznave utripa za sinhronizirano kardioverzijo. Tehnologija defibrilatorskih valovnih oblik se hitro razvija. Objavljene študije navajajo, da se učinkovitost valovnih oblik razlikuje. Izbira določene valovne oblike, vključno z obliko vala, dobavljeno energijo, učinkovitostjo in varnostjo, je bila izrecno izključena iz uporabe tega standarda. Vendar so bili zaradi kritične pomembnosti terapevtske valovne oblike utemeljitvi, ki obravnava razloge za valovno obliko in njeno izbiro, dodani komentarji.

_____________
201.1.1 * Scope
Replace the fourth existing paragraph by the following new paragraph:
This particular standard does not apply to implantable DEFIBRILLATORs, remote control
DEFIBRILLATORS, or separate stand-alone cardiac monitors (which are standardized by
IEC 60601-2-27:2011 [2] ). Cardiac monitors which use separate ECG monitoring electrodes
are not within the scope of this standard unless they are used as the sole basis for AED
rhythm recognition detection or beat detection for synchronized cardioversion. DEFIBRILLATOR
electrodes as described in 201.108 can also be used for ECG monitoring; however, due to the
larger electrode area, the requirements of IEC 60601-2-27 are not applicable for
DEFIBRILLATOR ELECTRODES.
201.2 Normative references
Replace, in the "Amendment" section, the existing reference IEC 60601-1-2, including its title,
by the following new reference:

standard) the CREEPAGE DISTANCES and AIR CLEARANCES of insulation between the
DEFIBRILLATOR or PACER high-voltage circuits and other parts, and between different parts
