Oxygen hpe shinggyin la lu ai jak ngu ai gaw, oxygen hpe shapraw ya ai jak langai mi re. Shi a npawt tara gaw nbung hpe garan ginhka ai hpaji hpe madung tawn ai. Langai, nbung hpe grai n-gun ja hkra shinggrup da ai. Dai hpang, nbung daw ni a n bung ai condensation point ni hpe akyu jashawn nna, gas-liquid garan ginhka ai lam gaw, masat da ai nbung laru hta byin pru wa ai. Hpang jahtum, nbung hpe hka ja ai shaloi, nbung hpe oxygen hte nitrogen ngu nna garan kau ya ai. Madung hku nna oxygen shapraw na matu lang ai majaw, oxygen concentrator ngu nna shamying ma ai. Oxygen hte nitrogen hpe jai lang ai lam law law nga ai majaw, oxygen concentrators ni hpe mungdan sut masa hta grai jai lang nga ai, grau nna, nhprang sut rai, tsi hpaji, sau nhprang, makawp maga lam zawn re ai bungli ni hta jai lang nga ai.
Kaga oxygen shinggyin la ai jak langai mi gaw, molecular sieve ni a hkam la lu ai atsam hpe jai lang ai. Hkum hkrang npawt tara ni hku nna hte n-gun kaba ai-n-gun rawng ai sau-n-lawm ai compressor hte n-gun jaw ai, nbung kata na nitrogen hte oxygen hpe garan nna oxygen law law lu la ai. Ndai zawn re ai oxygen concentrator gaw oxygen hpe lawan ladan hte grai law hkra shapraw ya ai majaw, hpung amyu myu a matu oxygen tsi lajang ai lam hte hkamja lam hpe gram lajang ai lam hta htuk manu ai. Shi gaw n-gun n law ai, hkying hkum mi hta 18 cents sha ra ai majaw, lang na matu manu n law ai.
