Measuring Oxygen Saturation with Pulse Oximetry | 測量脈搏氧飽和度 |
Assessment | 評估 |
1. Identify clients at risk for unstable oxygen status. | 確認病人有氧飽和度不穩(wěn)危險?!?/td> |
2. Identify medication/treatments that may influence oxygen saturation. | 確認藥物/治療可能影響氧飽和度?!?/td> |
3. Identify altered Hgb that may affect oxygen saturation. | 確認血紅蛋白變化可能影響氧飽和度?!?/td> |
4. Identify factors likely to interfere with accuracy of pulse oximeter . | 確認可能影響脈氧儀精確度的各種因素?!?/td> |
5. Assess pertinent laboratory values (Hgb and ABGs). | 評估相關(guān)化驗值(血紅蛋白和動脈血氣)?!?/td> |
6. Determine client-specific site appropriate to place pulse oximeter probe by measuring capillary refill. | 測定毛細血管再充盈情況,決定特定病人脈氧儀探針放置部位。 |
7. Determine previous baseline SpO2 from client's record. | 根據(jù)病歷記錄確定先前動脈血氧飽和度基線?!?/td> |
Implementation | 實施 |
1. Use Standard Protocol. | 應用標準護理措施?!?/td> |
2. Select site (ear, nail bed, or bridge of nose). If finger is selected, remove fingernail polish with acetone or polish remover. | 選擇部位(耳、甲床或鼻梁)。如選擇手指,用丙酮或除甲油除去指甲油?!?/td> |
3. Determine capillary refill at site. If less than 3 seconds, select alternative site. | 確定測量部位毛細血管再充盈情況。如慢于3秒,則另選他處。 |
4. If finger is chosen as monitoring site, support lower arm. Instruct client to keep sensor probe site still. | 如選擇手指為測量部位,請支撐小臂。囑咐病人穩(wěn)定探測部位?!?/td> |
5. Attach sensor probe to selected site, making sure photodetectors of light sensors are aligned opposite each other. | 將探測夾貼住所選部位,確保光敏原件感測器兩側(cè)對齊。 |
Nurse Alert: Wrong probe can cause burns. Check for latex allergies/sensitivity. | 注意:探測器選錯會導致灼傷。檢查有無乳膠過敏/敏感性。 |
6. Turn on oximeter by activating power. Observe pulse waveform/intensity display and audible beep. Compare oximeter pulse rate with client's radial pulse. | 打開電源,接通血氧計。觀察脈搏波形/強度和嘟嘟聲。對比血氧計脈率與病人橈動脈搏動?!?/td> |
7. Leave sensor probe in place until oximeter reaches constant value and pulse display reaches full strength during each cardiac cycle. Read SpO2 on digital display. | 留置探測器直到血氧計達到恒定值,每心動周期脈搏顯示達到充分強度。讀取數(shù)字顯示器的動脈血氧飽和度?!?/td> |
8. If continuous SpO2 monitoring is planned, check SpO2 alarm limits, which are preset by the manufacturer at a low of 85% and a high of 100%. Verify that alarms are on. Assess skin integrity under sensor probe and relocate sensor probe at least every 4 hours. | 如計劃連續(xù)測量動脈血氧飽和度,則檢查動脈血氧飽和報警設置,出廠時預設的值為低于85%和高于100%。確認報警器打開。評估探測器下皮膚完整性。至少每4小時重新放置探測器一次?!?/td> |
9. If intermittent or spot-checking SpO2 measurements are planned, remove probe and turn oximeter power off. Store probe in appropriate location. | 如是間斷性或抽樣檢查,除去探測器并關(guān)閉血氧計電源,將探測器貯藏于適當位置?!?/td> |
10. Use Completion Protocol. | 應用護理操作結(jié)束程序。 |
Evaluation | 評價 |
1. Compare SpO2 levels whenever oxygen therapy is initiated or discontinued, before and during sleep, before and during activity, and after removal of secretions with suctioning. | 比較氧療開始或結(jié)束、睡前和睡眠期間、活動前和活動時、及抽吸分泌物后的動脈血氧飽和度。 |
2. Observe for indications of hypoxemia, which include the presence of cyanosis, restlessness, altered respiratory patterns, and tachycardia. | 觀察是否出現(xiàn)低氧血癥跡象,包括發(fā)紺、不安、呼吸形態(tài)改變及心動過速?!?/td> |
3. Identify Unexpected Outcomes and Nursing Interventions | 確認意外結(jié)果及護理措施?!?/td> |
