"He passes out all the time."
Translation:הוא כל הזמן מתעלף.
מתעלף = pass out / faint. wiktionary fainting = desmaio
I don't know Portuguese (I used wiktionary.org here ), but you can ask these kinds of questions on hinative.com , I use the HiNative App a lot, (I know there are a lot of Brazilians on there, you can ask any language question for free and native speakers answer the questions) or the app/website: Reverso has Hebrew to Portuguese translation.
