Aparèy Oksijèn nan Yon Sèl Tablo
Oxygen Devices in One Table
🎭 Yon mask figi senp a 3 lit se pa yon regilaj dou. Se yon sak sou figi yon pasyan ki kenbe pwòp diyoksid kabòn li prizonye. Chak aparèy gen yon minimòm, yon maksimòm ak yon pyèj. Men yo tout la.
🎭 A simple face mask at 3 liters is not a gentle setting. It is a bag over a client's face that traps their own carbon dioxide. Every device has a floor, a ceiling and a trap. Here they all are.
💡 Ide prensipal
Chak aparèy gen yon debi minimòm ak yon pousantaj maksimòm. Mask senp yo bezwen omwen 5 L/min, mask san respirasyon yo bezwen yon sak gonfle, epi mask Venturi yo bay pousantaj egzak pou COPD.
Each device has a minimum flow and a maximum percentage. Simple masks need at least 5 L/min, non-rebreathers need an inflated bag, and Venturi masks give exact percentages for COPD.
🧠 Poukisa sa enpòtan
KANIL NAZAL: 1 jiska 6 L/min, apeprè 24 jiska 44% oksijèn; imidifye a 4 L/min ak pi wo; tcheke po dèyè zòrèy yo ak narin yo. MASK FIGI SENP: 5 jiska 8 L/min, apeprè 40 jiska 60%; janm pa anba 5 L/min sinon diyoksid kabòn ki soti nan respirasyon an akimile nan mask la. MASK AK RESPIRASYON PASYÈL: 6 jiska 10 L/min, apeprè 60 jiska 75%. MASK SAN RESPIRASYON: 10 jiska 15 L/min, jiska apeprè 90%; sak rezèvwa a dwe rete gonfle epi valv yon sèl direksyon yo dwe rete entak. MASK VENTURI: pousantaj presi soti nan 24 jiska 50% atravè adaptè ak kòd koulè, chwa pou COPD lè livrezon egzak la enpòtan. KANIL NAZAL WO DEBI bay oksijèn chofe epi imidifye ak debi ki pi wo anpil. Ipoksi bonè montre kòm ajitasyon, anksyete ak takikadi; ipoksi reta kòm siyanoz, bradikadi ak yon nivo konsyans k ap desann. Nan COPD, vize yon satirasyon 88 jiska 92% epi ajiste dòz la olye pou w refize bay yon pasyan ipoksik oksijèn.
NASAL CANNULA: 1 to 6 L/min, about 24 to 44% oxygen; humidify at 4 L/min and above; check the skin behind the ears and the nares. SIMPLE FACE MASK: 5 to 8 L/min, about 40 to 60%; never below 5 L/min or exhaled carbon dioxide accumulates in the mask. PARTIAL REBREATHER: 6 to 10 L/min, about 60 to 75%. NON-REBREATHER: 10 to 15 L/min, up to about 90%; the reservoir bag must stay inflated and the one-way valves intact. VENTURI MASK: precise percentages from 24 to 50% through color-coded adapters, the choice for COPD when exact delivery matters. HIGH-FLOW NASAL CANNULA delivers heated, humidified oxygen at much higher flows. Early hypoxia shows as restlessness, anxiety and tachycardia; late hypoxia as cyanosis, bradycardia and a falling level of consciousness. In COPD, aim for a saturation of 88 to 92% and titrate rather than withholding oxygen from a hypoxic client.
🏥 Nan lavi reyèl
😰 Yon pasyan apre operasyon vin ajite epi li kontinye rale dra yo. Enfimyè lannwit la sipoze se doulè epi li lonje men l pou opyoyid la. Satirasyon an montre 87%. Ajitasyon se premye siy ipoksi, epi yon opyoyid ta vin agrave l. Oksijèn anvan, apre re-evalye, apre trete doulè a si li toujou la.
😰 A post-op client becomes restless and keeps pulling at the sheets. The night nurse assumes pain and reaches for the opioid. The saturation reads 87%. Restlessness is the first sign of hypoxia, and an opioid would have deepened it. Oxygen first, then reassess, then treat pain if it is still there.
📌 Sa pou retni
- Kanil 1–6 L; mask senp omwen 5 L; mask san respirasyon 10–15 L ak yon sak gonfleCannula 1–6 L; simple mask at least 5 L; non-rebreather 10–15 L with an inflated bag
- Venturi pou pousantaj presi nan COPD; satirasyon sib 88–92%Venturi for precise percentages in COPD; target saturation 88–92%
- Ajitasyon ak takikadi se ipoksi bonè; siyanoz se retaRestlessness and tachycardia are early hypoxia; cyanosis is late
📖 Tèm nan leson sa a
Mask san re-respirasyon (non-rebreather) (Non-rebreather mask): Yon mask ak yon sak rezèvwa ki bay jiska apeprè 90% oksijèn nan 10 jiska 15 L/min, toutotan sak la rete gonfle.
Mask Venturi (Venturi mask): Yon mask ak adaptè koulè ki bay pousantaj oksijèn egzak, yo prefere l pou COPD.
✅ Teste tèt ou
Mask figi senp yon pasyan regle a 3 L/min. Kisa enfimyè a dwe fè?A client's simple face mask is set at 3 L/min. What should the nurse do?
- Chanje pou yon mask san respirasyon ak menm debi 3 L/min lanSwitch to a non-rebreather mask at the same 3 L/min flow
- Ogmante debi a a omwen 5 L/min pou chase diyoksid kabòn lanIncrease the flow to at least 5 L/min to flush carbon dioxide
- Retire oksijèn lanRemove the oxygen
- Anyen; regilaj la apwopriye pou yon mask senpNothing; the setting is appropriate for a simple mask
Repons: B · Ogmante debi a a omwen 5 L/min pou chase diyoksid kabòn lan
Yon mask senp bezwen omwen 5 L/min pou chase diyoksid kabòn ki soti nan respirasyon an soti nan mask la. Chanje pou yon mask san respirasyon a 3 L/min pi mal, paske mask sa a bezwen 10 jiska 15 L/min pou kenbe sak rezèvwa li plen.
A simple mask needs at least 5 L/min to flush exhaled carbon dioxide from the mask. Switching to a non-rebreather at 3 L/min is worse, because that mask needs 10 to 15 L/min to keep its reservoir bag filled.
Sak rezèvwa a sou yon mask san respirasyon efondre nèt ak chak respirasyon. Kisa sa endike?The reservoir bag on a non-rebreather mask collapses completely with each breath. What does this indicate?
- Debi a twò ba oswa gen yon fwit; sak la dwe rete gonfleThe flow is too low or there is a leak; the bag must stay inflated
- Aparèy la ap mache kòrèkteman epi li pa bezwen okenn ajistemanThe device is working correctly and needs no adjustment
- Pasyan an pa bezwen oksijèn ankòThe client no longer needs oxygen
- Yo dwe chanje mask la pou yon kanil nazal a 6 L/minThe mask should be changed to a nasal cannula at 6 L/min
Repons: A · Debi a twò ba oswa gen yon fwit; sak la dwe rete gonfle
Sak la dwe rete omwen pasyèlman gonfle pou pasyan an pran oksijèn nan yon rezèvwa, pa lè chanm lan. Yon ti bese ak chak respirasyon nòmal, men efondreman konplè pa nòmal, kidonk aparèy la pa ap mache kòrèkteman epi li bezwen ajisteman.
The bag must remain at least partially inflated so the client draws from a reservoir of oxygen, not room air. A slight dip with each breath is normal, but complete collapse is not, so the device is not working correctly and needs adjustment.
Ki siy bonè ki sijere yon pasyan ap vin ipoksik?Which early sign suggests a client is becoming hypoxic?
- Pa reponn a vwaUnresponsiveness to voice
- Siyanoz lèv yoCyanosis of the lips
- Ajitasyon ak takikadiRestlessness and tachycardia
- Bradikadi ak ipotansyonBradycardia and hypotension
Repons: C · Ajitasyon ak takikadi
Ajitasyon, anksyete ak takikadi parèt an premye. Siyanoz, bradikadi ak konsyans ki bese se siy reta ak siy ki bay kè sote.
Restlessness, anxiety and tachycardia appear first. Cyanosis, bradycardia and decreased consciousness are late and ominous.
