3.氣道壓力上限設(shè)置偏低，4.通氣參數(shù)的改變。解決方法:1.檢查患者端管路并校正通暢，2.檢查患者呼吸道狀態(tài)，3.重新校正報警設(shè)置值，4.重新計算和調(diào)整通氣參數(shù)。故障6故障現(xiàn)象:氣道壓力下限報警?？赡茉?1.患者端氣體管路漏氣，2.報警設(shè)置值太高，3.患者順應(yīng)性的改變。解決方法:1.檢查管路，校正漏氣部分，2.重新設(shè)定報警值，3.檢查患者順應(yīng)性狀態(tài)。故障7故障現(xiàn)象:氣道壓力參數(shù)無指示?？赡茉?1.吸氣通道與壓力傳感器之間的連接管子松脫或接反，2.氣源用盡。解決辦法:1.重新接好吸氣通道與壓力傳感器之間的連接管，2.更換氣源。故障8故障現(xiàn)象:負(fù)壓高報警。故障分析與檢修:當(dāng)儀器出現(xiàn)負(fù)壓高報警時，要特別注意儀器內(nèi)負(fù)壓泵的聲音，可以聽到負(fù)壓泵負(fù)荷很大，并且聲音低沉。這時，打開機(jī)器蓋后看到負(fù)壓泵上接著一個白色的空氣過濾器，過濾器發(fā)黑，證明空氣過濾器已堵塞，更換空氣過濾器，故障排除。故障9故障現(xiàn)象:潮氣量和設(shè)定值偏差大。可能原因:1.流量傳感器損壞，2.流量傳感器需要定標(biāo)，3.呼出氣體壓力采樣管堵塞。解決辦法:1.更換流量傳感器，2.對流量傳感器檢查和重新標(biāo)定，3.更換呼出氣體壓力采樣管。故障10故障現(xiàn)象:在PEEP。湖北AESCULAPAxel300W冷光源主機(jī)芯片級維修檢測電網(wǎng)電源正常。打開主機(jī)，檢查內(nèi)部電源。</p><div

禁止將所有胸導(dǎo)測量位置一次性進(jìn)行涂抹，這將會造成體表短路，影響測出波形效果。請莫使用水或生理鹽水進(jìn)行測量，這將會加快電極的腐蝕及老化。三、常見故障及排除1、打直線答：1)按了導(dǎo)聯(lián)封閉鍵；按了導(dǎo)聯(lián)封閉鍵屏幕上顯示"導(dǎo)聯(lián)封閉"或"[0]"并出現(xiàn)打直線，只要再按一次"INST"或"RESET"直至"導(dǎo)聯(lián)封閉"、"[0]"消失。2)導(dǎo)聯(lián)脫落打直線；屏幕上顯示"導(dǎo)聯(lián)脫落"或?qū)?lián)閃動，一般要看是某導(dǎo)聯(lián)、某幾導(dǎo)聯(lián)打直線還是全部打直線，首先檢查對應(yīng)導(dǎo)聯(lián)電極是否脫落，各個接觸點(diǎn)是否良好。其次更換一條導(dǎo)聯(lián)線試試，再不行就是機(jī)器本身問題。3)數(shù)據(jù)出界打直線；屏幕上顯示"數(shù)據(jù)出界"或"OVR"，首先檢查各個電極安放是否穩(wěn)妥、病人是否燥動不安，其次更換條導(dǎo)聯(lián)線試一下。再不行就是主板問題。4)無心率顯示所有導(dǎo)聯(lián)打直線；請打開機(jī)器，用萬用表測量放大部分的+5V，±12V是否正常，（用萬用表測量的電壓值應(yīng)為+5V左右，±）若不正常則是主板DC-DC變換電路元件損壞。2、打印不清答：1)看紙倉蓋上兩銅軸是否磨損過大（除十二道機(jī)外）2)打印頭不良會引起打印不清，更換同型號打印頭試下。3)打印頭支架、彈簧變形會引起打印不清。4)打印頭使用時間長，打印頭贓或有污垢。</p><p> 3)圓盤電極圓盤電極多數(shù)采用銀質(zhì)材料，其背面有一根導(dǎo)線，如圖1-1-6所示。有的電極為了減輕基線漂移及移位偽差在其凹面處鍍上一層氯化銀。值得注意的是，該電極在使用一段時間后必須重新鍍上氯化銀。(4)懸浮電極懸浮電極分為長久性和一次性使用的二種。其中長久性懸浮電極又叫作帽式電極，其結(jié)構(gòu)是把鍍氯化銀或燒結(jié)的Ag-AgCl電極安裝在凹槽內(nèi)，它與皮膚表面有一空隙。如圖1-1-7所示，使用時，應(yīng)在凹槽內(nèi)涂滿導(dǎo)電膏，用中空的雙面膠布把電極貼在皮膚上。由于導(dǎo)電膏的性質(zhì)柔軟，它粘附著皮膚，也粘附著電極，當(dāng)肌肉運(yùn)動時，電極導(dǎo)電膏和皮膚接觸處不易發(fā)生變化，起到接觸穩(wěn)定的作用。一次性懸浮電極也叫作鈕扣式電極，其結(jié)構(gòu)是將氯化銀電極固定在泡沫墊上，底部也吸附著一個涂有導(dǎo)電膏的泡沫塑料圓盤，如圖1-1-8(b)所示。使用前，圓盤周圍粘有一層保護(hù)紙，封裝在金屬箔制成的箱袋內(nèi)，用時取出，剝?nèi)ケＷo(hù)紙，即可使用，如圖1-1-8(a)、(b)所示。由于泡沫塑料與人體皮膚貼附緊密，一般不會引起紙，即可使用，如圖1-1-8(a)、(b)所示。由于泡沫塑料與人體皮膚貼附緊密，一般不會引起接觸不良而產(chǎn)生干擾。但這種電極只能使用一次。。其以后部分比較復(fù)雜，且為多面板檢測判斷比較困難。</p><div

CT球管是CT機(jī)中重要部件，正確合理的使用可達(dá)到滿意的掃描效果，并可延長球管使用壽命，為醫(yī)院的經(jīng)濟(jì)效益帶來很大影響。1.預(yù)熱(掃描程序)預(yù)熱掃描是CT機(jī)停機(jī)超過3h以上所必須進(jìn)行的程序掃描，其目的是保證機(jī)器能執(zhí)行正常的掃描工作，延長球管使用壽命，并保證良好的圖像。2.正確選定掃描條件根據(jù)檢查要求不同適當(dāng)選擇既適合病人體型、部位的掃描條件，又可在保證圖像質(zhì)量的基礎(chǔ)上采用宜低不宜高的曝光條件，比較大限度的保護(hù)球管。3.合理安排病人根據(jù)病人掃描要求不同，可將費(fèi)時掃描和短時掃描的病人、將常規(guī)掃描和高精度掃描的病人、將增強(qiáng)和不需增強(qiáng)的病人、將大曝光量和小曝光量掃描的病人適當(dāng)調(diào)整分開，以利球管能有間歇時間。4.環(huán)境條件的控制要保證足夠容量的空調(diào)以利球管散熱，要保證溫度恒定，保持室內(nèi)清潔，減少塵埃，以利球管散熱器通暢。5.適當(dāng)使用程序掃描程序掃描方式是CT機(jī)已設(shè)置的掃描條件，其優(yōu)越性是可按既定要求選擇程序，自動掃描，達(dá)到完美的檢查目的；不足的是球管曝光的間歇時間縮短，散熱減少，負(fù)荷積累，縮短球管的使用壽命，故適當(dāng)?shù)倪x用程序掃描可有效的保護(hù)球管。6.杜絕“曝光中止”當(dāng)球管準(zhǔn)備就緒待曝光時。湖北AESCULAPAxel300W冷光源主機(jī)芯片級維修</p><p
