5.3.FITTING MASK OR MOUTHPIECE AND FILTER

Select mask or mouthpiece and ﬁ lter as appropriate for the patient and ﬁ t to the demand valve

by pushing it over the 22 mm insert female tapered outlet on the patient port (see Fig. 1).

NOTE: Some patients ﬁ nd masks claustrophobic and may ﬁ ght against the use of EASE II if

o ered in this way. With such patients use of a mouthpiece is recommended.

5.4.TESTING PRIOR TO ADMINISTRATION

Units should be checked by lightly pressing the test button (see ﬁ g 1., ﬁ g.2). Gas should be

heard ﬂ owing through the mask or mouthpiece. On releasing the test button, the ﬂ ow should

stop.

NOTE: If the system does not operate i.e. does not give a gas ﬂ ow on depressing the test

button or the system does not stop giving ﬂ ow, turn o the cylinder or disconnect from the

gas source and refer to the TROUBLESHOOTING chart in Section 9.

6. OPERATIONS

6.1.ADMINISTERING OF MEDICAL GASES

Medical gases 50/50% O2/N2O or 100 % O2 should only be administered by persons trained to

do so and under qualiﬁ ed medical supervision.

Cylinder contents must be checked regularly during therapy and the cylinder replaced as

necessary.

1. Calmly explain to the patient purpose and operation of the demand valve. Reassure and

encourage him/her to breathe normally.

NOTE: Patients do not have to remove the mask or mouthpiece during exhalation.

2. Place the mask on the patient and support the mask over the mouth and nose, with the

patient breathing normally and not remove the mask when exhaling.

NOTE: If a mouthpiece is ﬁ tted, instruct them to hold it between their teeth, sealing on it with

their lips and to breathe through their mouth only.

3. Instruct the patient to breathe through the demand valve as required to reduce the level of

pain. (Continuous use is often unnecessary).

NOTE: Supervisory personnel can help support the mask, if should the patient is incapable

of holding it.

4. Constantly monitor the patient and the cylinder contents during administration.

Check volume of gas in the cylinder and replace the cylinder if necessary.

5. The administration of 50/50 O2/N2O may cause the patient to become drowsy. The seal

between the mouth and the demand valve will be lost and ambient air will be inhalated. The

patient will then begin to regain consciousness and an awareness of pain; and should be

encouraged to breathe the gas again.

6.2.AFTER USE

1. When treatment has been completed, close the cylinder valve and operate the test button

to de-pressurize the system or disconnect the demand valve from the wall outlet or quick

connector.

• Pravidelně kontrolujte hadici během používání, zda není roztržená, ohnutá, překroucená

nebo vystavená nadměrnému tahu.

• Pravidelně kontrolujte přívod plynu nebo jeho obsah v láhvi.

5.2.PŘIPOJENÍ ČISTÍCÍHO ADAPTÉRU

• Pokud je v systému

zahrnut čisticí adaptér,

připevněte jej k

odběrovému ventilu jeho

natlačením na pacientský

ventil (viz Obr. 1).

• Poté připojtevýdechovou

trubku k čisticímu

adaptéru.

Pozn.: Čisticí adaptér by

měl být použit, když se

EASEII pro O2/N2O používá

5.3.PŘIPEVNĚNÍ MASKY NEBO ÚSTENKY A FILTRU

Zvolte vhodnou masku nebo ústenka a ﬁ ltr pro pacienta a připevněte k odběrovému ventilu

natlačením na kuželovou zásuvku o průměru 22 mm na pacientském ventilu (viz Obr. 1).

Pozn.: Někteří pacienti mohou při použití masek trpět klaustrofobií a mohou se vzpírat proti

použití EASEII, když je nabízeno tímto způsobem. U takových pacientů se doporučuje použít

ústenku.

5.4.ZKOUŠENÍ PŘED PODÁVÁNÍM

Systémy s testovacím tlačítkem by měly být kontrolovány lehkým tisknutím testovacího tlačítka

(viz obr. 1., obr.2). Měl by být slyšen plyn proudící maskou nebo ústenkou. Po puštění testovacího

tlačítka by se průtok měl zastavit.

Pozn.: Jestliže systém nepracuje, tj. při stisknutí testovacího tlačítka nedojde k průtoku plynu

nebo se průtok nezastaví, zavřete láhev nebo odpojte systém z koncové zásuvky a použijte

tabulku odstraňování poruch v článku 9.

6. POUŽÍVÁNÍ

6.1.PODÁVÁNÍ SMĚSI 50/50 O2/N2O

Směs 50/50 O2/N2O by měly podávat pouze osoby k tomu vyškolené a pod dohledem

kvaliﬁ kovaných zdravotníků.

Během terapie by se měl pravidelně kontrolovat obsah láhve. Láhev by se měla v případě

potřeby vyměnit.

1. Poklidně vysvětlete pacientovi, co se chystáte dělat. Uklidněte ho a povzbuďte ho, aby

dýchal normálně.

Pozn.: Pacienti během výdechu nemusí masku ani náustek odstraňovat.

2. Podejte pacientovi masku a poraďte mu, jak ji má držet přes ústa a nos, aby dýchal normálně

a při výdechu masku neodstraňoval.

Pozn.: Pokud je nasazena ústenka, poraďte mu, jak ji má držet mezi zuby, že má použít rty

jako těsnění a dýchat pouze ústy.

3. Instruujte pacienta, že má dýchat přes odběrový ventil, aby se snížila bolest (nepřetržité

používání často není nutné).

Pozn.: Ošetřovatelé mohou pomoci masku podepřít, pokud by pacient nebyl schopen.

4. Během podávání neustále sledujte pacienta a obsah láhve. Kontrolujte obsah plynu v láhvi a

v případě potřeby láhev vyměňte.

5. Podávání směsi 50/50 O2/N2O může vyvolat ospalost pacienta. Tím dojde ke ztrátě těsnosti

mezi ústy a odběrovým ventilem a k vdechování okolního vzduchu. Pacient začne přicházet

k vědomí a uvědomí si bolest a měl by být vyzván, aby znovu vdechoval plyn.

6.2.PO POUŽITÍ

1. Po dokončení léčby zavřete lahvový ventil a stiskněte testovací tlačítko, aby došlo k

odtlakování systému, nebo odpojte odběrový ventil od zásuvky ve zdi nebo rychlospojky.

2. Vyčistěte systém dle popisu v článku 7.

Nepoužívejte čístící roztoky obsahující čpavek!

Zařízení nevystavujte působení vody ani jiné kapaliny.

Nevystavujte vysokým teplotám (např. v autoklávu), pokud není uvedeno jinak.

Pro aplikaci čistícího prostředku nesmí být použitý postřik, v opačném případě hrozí vniknutí

postřiku do vnitřních částí ventilu a jeho kontaminaci či poškození.

Pro čištění nepoužívejte tlakové mytí, mohlo by to způsobit poškození nebo kontaminaci

ventilu.

Pokud došlo k jakékoliv kontaminaci vnitřních částí ventilu v žádném případě jej nepoužívejte,

stáhněte jej z provozu.

7.1.ČIŠTĚNÍ SESTAV VDECHOVÉHO A PACIENTSKÉHO VENTILU

Pokud je použit antibakteriální ﬁ ltr a ventil nebyl znečištěn tělesnými tekutinami, není nutné čistit

ventil po každém použití. Nečistoty odstraňte měkkým hadříkem navlhčeným v bezolejnaté,

mýdlové vodě a opláchněte čistou vodou. Pokud byl ventil kontaminován krví nebo zvratky,

čištění je nezbytné. Postupujte dle jednoho z níže popsaných postupů pro čištění:

1. Vyšroubujte sestavu pacientského ventilu z odběrového ventilu (Obr. A a vyjměte sestavu

vdechového ventilu (Obr. B).

2. Vyjměte silikonové membrány ventilu z výdechového ventilu (viz. Obr. C,D). Vyvarujte se

nadměrnému natahování a narušení silikonových membrán během demontáže.

3. Pokud používáte antibakteriální ﬁ ltr, nemusíte ventil čistit po každém použití. Výrobce však

doporučuje toto čištění provést. Pokud je ventil kontaminovaný krví nebo zvratky, čištění je

nezbytné. Postupujte dle jedné z čistících metod popsaných níže:

a. Buď omyjte všechny části v teplé vodě o max. teplotě 60°C s použitím vhodného

dezinfekčního prostředku. Mechanická odolnost komponentů (Výdechový ventil, nádechový

disk, membrána odběrového ventilu, membrána výdechového ventilu) je zaručena do 20

cyklů sterilizace za níže uvedených podmínek.

Příklad čištění studeným dezinfekčním prostředkem:

Meliseptol: Nečistoty odstraňte měkkým hadříkem navlhčeným v teplé vodě s max. trvání 30

sekund. Dezinfekci aplikujte na komponenety (aplikace dezinfekčního prostředku po dobu 1

minuty). Po aplikaci dezinfekce, vyčistěte komponenty tekoucí studenou vodou z vodovodu.

Komponenty by měly být opatrně usušeny měkkým neabrazivním hadříkem.

b. Nebo umístěte části do autoklávu na 5 min při teplotě 134° C nebo na 20 min při teplotě

121°C. Po ukončení cyklu, počkejte, až části vychladnou a zkontrolujte, zda nejsou poškozené.

Smontujte zařízení (viz kapitola 5).

Mechanická odolnost komponentů (Výdechový ventil, nádechový disk, membrána

odběrového ventilu, membrána výdechového ventilu) je zaručena do 20 cyklů sterilizace za

výše uvedených podmínek.

Později může docházet k degradaci plastových látek.

7.2.DEMONTÁŽ ODBĚRNÉHO VENTILU

1. Vyšroubujte sestavu pacientského ventilu z odběrového ventilu (Obr. A a vyjměte sestavu

vdechového ventilu (Obr. B).

2. Vyjměte silikonové membrány ventilu z výdechového ventilu (viz. Obr. C,D).

Vyvarujte se nadměrnému natahování a narušení silikonových membrán během demontáže.
