Iyo inoshanda nheyo ye spo2 sensor
The zvechivanhuSpO2kuyema nzira kuunganidza ropa kubva mumuviri, uye kushandisa ropa gasi analyzer ye electrochemical ongororo kuyera chidimbu kumanikidzwa kweropa okisijeni PO2 kuverenga kuzara kweokisijeni muropa.Nekudaro, yakanyanya kunetsa uye haigone kuramba ichitariswa.Saka, oximeter yakatanga.
Iyo oximeter inonyanya kuumbwa ne microprocessor, ndangariro (EPROM uye RAM), maviri edhijitari-ku-analogi anoshandura anodzora maLED mudziyo .filters uye anokudza chiratidzo chinogamuchirwa nephotodiode, uye digitize chiratidzo chinogamuchirwa kuti chipe microprocessor's analog-to. -digital converter inoumbwa.
Iyo oximeter inotora chigunwe sleeve photoelectric sensor.Iwe unongoda kuisa sensor pamunwe paunenge uchiyera.uchishandisa chigunwe sechigadziko chakajeka chehemoglobin, uye shandisa chiedza chitsvuku chine wavelength ye660 nm uye pedyo-infrared chiedza chine wavelength ye940 nm semwaranzi.Pinda panobva mwenje uye uyere kusimba kwekufambiswa kwechiedza kuburikidza nematishu mubhedha kuti uverenge huwandu hwehemoglobin uye kuzara kweokisijeni muropa.
Inoshanda vanhu veoximeter
1.Vanhu vane zvirwere zvevascular (coronary heart disease, hypertension, hyperlipidemia, cerebral thrombosis, nezvimwewo)
Pane lipid deposits muvascular lumen, uye ropa harina kutsetseka, izvo zvichaita kuti kuomerwa kweokisijeni.
2.Varwere vemwoyo
Viscous ropa, pamwe chete nekuoma kwema coronary arteries, inoderedza vascular lumen, zvichiita kuti ropa ripere uye kuoma kweokisijeni.Muviri "hypoxia" zuva nezuva.Kureba kwenguva refu munyoro hypoxia, mwoyo, uropi uye dzimwe nhengo dzine yakakwira okisijeni kushandiswa zvichaderera zvishoma nezvishoma.Nokudaro, kushandiswa kwenguva refu kwepulse oximeter kuyera ropa reokisijeni yehutano hwemwoyo uye cerebrovascular varwere vanogona kudzivirira kuitika kwengozi.Kana hypoxia ikaitika, sarudzo yekuwedzera okisijeni inoitwa nekukurumidza, iyo inogona kunyatso kuderedza mukana wekurwisa chirwere.
3.Vanhu vane zvirwere zvekufema (asthma, bronchitis, chronic bronchitis, pulmonary heart disease, etc.)
Kuongororwa kweokisijeni yeropa kune varwere vekufema kwakakosha chaizvo.Kune rimwe divi, matambudziko ekufema anogona kukonzera kusakwana kweokisijeni kutora.Kune rimwe divi, kuramba kweasthma kunogonawo kuvhara nhengo diki, zvichiita kuti kuchinjana kwegasi kuve kwakaoma uye zvichitungamira ku hypoxia.Zvinokonzera madhigirii akasiyana ekukuvadza kumoyo, mapapu, uropi uye kunyange itsvo.Naizvozvo, kushandiswa kwepulse oximeter kuona zvirimo muropa okisijeni kunogona kuderedza chiitiko chekufema.
4.Vakuru pamusoro pe60
Muviri wemunhu unovimba neropa kufambisa oxygen.Kana pane ropa shoma, pachava nemuzvarirwo kuva neokisijeni shoma.Neokisijeni shoma, chimiro chemuviri chinodzikira.Nokudaro, vakwegura vanofanira kushandisa pulse oximetry kuti vaongorore ropa reokisijeni zuva rega rega.Kamwe ropa reokisijeni rave pasi peyero yekunyevera, oxygen inofanira kuwedzerwa nekukurumidza sezvinobvira.
5.Sports uye kugwinya mhomho
Kushanda kwenguva refu kwepfungwa uye kurovedza muviri kwakasimba kunowanzoita hypoxia, iyo inokanganisa myocardial uye hutano hwehuropi.Zvakadai sevadi vemitambo;vashandi vepfungwa;Plateau travel enthusiasts.
6.Vanhu vanoshanda kupfuura maawa 12 zuva rimwe chete
Kushandiswa kweokisijeni muuropi kunotora 20% yeokisijeni yemuviri wese, uye kushandiswa kweokisijeni muuropi kunowedzera nekushanduka kwebasa repfungwa.Muviri wemunhu unogona kutora okisijeni shoma, wodya yakawanda, uye wodya zvishoma.Pamusoro pekukonzera dzungu, kuneta, kutadza kurangarira, kunonoka kupindura uye mamwe matambudziko, zvinogona zvakare kukonzera kukuvadza kwakakomba kuuropi uye myocardium, uye kunyange kufa nekushanda zvakanyanya.Naizvozvo, vanhu vanodzidza kana kushanda maawa gumi nemaviri pazuva vanofanirwa kushandisa pulse oximetry kuti vaedze okisijeni yeropa zuva rega rega Zvirimo, kutarisa hutano hweokisijeni yeropa nguva nenguva, kuve nechokwadi chemoyo uye hutano hwehuropi.
