Gydymas

2020-04-04Temperatūra

  • Rekomenduojamas vaistas: Paracetamolis
  • Temperatūra suaktyvina imuninę sistema, todėl patartina nenaudoti paracetamolio (nebent temperatūra pakyla virš 38.5°C).
  • Paracetamolis pradeda veikti maždaug po 30 min. po suvartojimo.
  • Paracetamolio poveikis trunka apie 4-6 valandas.
  • Nenaudoti ibuprofeno ir aspirino, nes jie pristabdo antikūnių gamybą, kurių reikia kovai prieš virusą (nebent gydytojas nurodė vartoti).

2020-04-22Viešai parduodami nereceptiniai vaistai

Turėkite vaistų namuose porą savaičių į priekį, kad sirgdamas neužkrėstumėte kitų pirkdami.

Atminkite, kad geriausias būdas gauti visus reikalingus vitaminus ir mineralus yra per sveiką mitybą.

2020-04-22Vitaminas C

Vitaminas C yra svarbi maistinė medžiaga, kuri palaiko imuninės sistemos funkcionavimą.

Profilaktiškai karantino periodu :

  • Suagusiems: 500mg
  • Vaikams: 250mg

Vitamino C dienos norma yra apie 1 gramą per kūno kilogramą per dieną.

2020-04-04Vitaminas D

Vitamino D papildai apsaugo nuo ūminių kvėpavimo takų infekcijų, įskaitant peršalimą ir gripą.

Vartoti per dieną:

  • Profilaktiškai karantino periodu: 800-1000 IU
  • Įtariant kontaktą su viruso nešiotoju: 1000-2000 IU

Vitamino D dienos norma yra 400-800 IU per dieną. 1 IU = 0.025 μg
Tyrimai rodo, kad geriausiai virusą paveikė pas tuos, kurie naudojo kas dieną po 800 IU (20μg).

2020-04-22N-Acetyl-Cysteine (NAC)

N-acetilcisteinas ženkliai sušvelnina į gripą panašius simptomus ir gerinina ląstelių imunitetą.

Vartoti per dieną:

  • Profilaktiškai karantino periodu: 600 mg 
  • Įtariant kontaktą su viruso nešiotoju: 600 mg du kartus per dieną (ryte ir vakare)

Gripo virusų infekuotų pacientų tyrimas parodė, kad simptominė forma išsivystė: 79% pacientų placebo grupėje, ir tik 25% pacientų gydomiems NAC.

2020-04-04Cinkas ir Quercetinas (Zinc and Quercetin)

Cinkas stabdo viruso dauginimąsi ląstelės viduje.
Quercetinas (cinko jonoforas) padeda patekti cinkui į ląstelės vidų.

Vartoti per dieną - Cinkas:

  • Profilaktiškai karantino periodu: 25 mg

Vartoti per dieną - Quercetinas:

  • Įtariant kontaktą su viruso nešiotoju: 500 mg
  • Pasireiškus simptomams: 500 mg du kartus per dieną (vakare ir ryte)
  • Sunkėjant simptomams: didinti iki 3 g

Mokslinis tyrimas naudojo nuo 3g iki 7g Querecetine per dieną.

Disinfecting and reusing Filters

Some masks and filters can be disinfected without reducing the filtration efficiency of the meltblown layer. Two best methods found:

  1. 75°C Hot Air for 30 mins. Mask can be reused 20 times.
  2. UV (254 nm, 8W) for 30 min. Mask can be reused 10 times.

Disinfecting masks by using steam, 75% alcohol or chlorine-based solution will reduce filter efficiency and is not recommended.
