Yambiro

• Uku hakusi kuongororwa. Tsanangudzo yekurira kwemoyo inopihwa neEko Murmur Analysis Software inongoitirwa kupa rubatsiro rwekuchipatara sarudzo kumurapi, anogona kushandisa mhedzisiro pamwe nekuongorora kwavo uye kutonga kwekiriniki. Dudziro dzacho hadzisi zvirwere.
• Iyo Eko Murmur Analysis Software inogona kupa otomatiki kududzira komputa. Dudziro inogadzirwa nekombuta haigoni kutsiva kufunga kwakanaka kwezvokurapa nenyanzvi yakadzidziswa. Naizvozvo, chiremba anofanira kugara achidzokororaview kududzira uye kuongorora kwekupedzisira kunofanira kuwanikwa nguva dzose nachiremba. Kutungamirirwa kwakakodzera uye kushandiswa kwechigadzirwa ichi ibasa rechiremba.
• Hunhu hwekududzirwa kwekombuta hunoenderana zvakanyanya nemhando ye data yakaiswa. Ongorora chete zvemhando yepamusoro zvakarekodhwa zvemanzwi emwoyo.
• Iyo software inongozivisa murapi nezvekuvapo kana kusavapo kwekugunun'una muphonocardiogram, uye kana iripo, ingave iyo kugunun'una iri systolic kana diastolic, uye chimiro kana chisina mhosva. Chiremba anofanirwa kuitisa kuongororwa kwakazara kwekugunun'una kwakaonekwa kuti aone kubva kune iyo valve (s) inobuda uye chiyero chechirwere chechirwere chinoratidza. Izvi zvingada kumwe kuedzwa, sezvakaratidzwa.
• Iyo Eko Murmur Analysis Software haina kuitirwa senzira yega yekuongororwa. Kuonekwa kwekusagadzikana mumanzwiro emwoyo anopihwa nesoftware akakosha chete kana akashandiswa pamwe nekududzirwa kwechiremba.
• Iyo software yakadzidziswa kushandisa marekodhi anonzwika akatorwa kubva kune ina yakajairwa cardiac auscultation nzvimbo (kureva, kurudyi kumusoro kwekumusoro muganhu, kuruboshwe kumusoro kwekumusoro muganhu, kuruboshwe kuzasi sternal muganhu, uye cardiac apex). Kuita kwemudziyo hakuzivikanwi kana uchiongorora ruzha rwakatorwa kubva kumwe kunhu pamutumbi wemurwere.

Zviratidzo Zvekushandisa

Iyo Eko Murmur Analysis Software inoitirwa kupa rutsigiro rwesarudzo kuvarapi mukuongorora kwavo kurira kwemwoyo yevarwere. Iyo software inoongorora manzwi emwoyo uye phonocardiograms (uye ECG zviratidzo, kana zviripo). Iyo software ichaona otomatiki kugunun'una kungave kuripo, uye nguva yekugunun'una uye hunhu, kusanganisira S1, S2, isina mhosva kugunun'una kwemoyo, kugunun'una kwemoyo, uye kusavapo kwekugunun'una kwemoyo. Iyo Eko Murmur Analysis Software haina kuitirwa senzira yekuongororwa uye ndeyekushandiswa munzvimbo dzinopihwa hutano nevarapi. Kududzirwa kwemanzwi emwoyo anopihwa nesoftware kunongoreva kupa rutsigiro rwechisarudzo kumurapi, anogona kushandisa mhedzisiro pamwe chete nekuongorora kwavo uye kutonga kwekiriniki. Dudziro dzacho hadzisi zvirwere. Iyo Eko Murmur Analysis Software yakagadzirirwa kushandiswa kune vana uye varwere vakuru.

Zviziviso

Iri bhuku rinopa mirairo yekushandiswa kweEko Murmur Analysis Software. Zvinofungidzirwa kuti mushandisi anoziva nezvekutanga Eko software yekushandisa panharembozha uye desktop zvishandiso. Maitiro akajairwa ekuita auscultation anofanirwa kuteverwa anosanganisira kuderedzwa kweruzha uye kwakaringana kumira kwemurwere paunenge uchitora data yeEko Murmur Analysis Software. Zviziviso zvakaitwa nechinhu ichi zvinogona kuwanikwa, uye hazvisi zvekuongororwa kuzere kwemoyo. Nhoroondo yemurwere uye mhedzisiro yekuongororwa kwemuviri inofanirwa kutariswa panguva yekuita sarudzo. Iyo Eko Murmur Analysis Software haikwanisi kudzosera mhedzisiro kana Eko CORE kana DUO stethoscope isingakwanise kubatana nenharembozha neBluetooth kana nharembozha isingakwanise kubatana neinternet. Iyo Eko Murmur Analysis Software inoda shoma internet yekubatanidza kumhanya. Iyo yakakurudzirwa yekumhanyisa yekumhanyisa ye mobile app ndeye 4 Mbps. 4G cellular data service kana yakafanana inokurudzirwa.Iyo software haifaniri kushandiswa kune varwere apo chiremba ane dambudziko rekugadzirisa neEko CORE kana DUO stethoscopes. Kurongeka kweSoftware kunogona kutambura kana murwere akafuta kana kuti ane ruzha rwepulmonary. Mutongo wekupedzisira pachirwere ichi uchiri kuvashandi vezvokurapa vanokwanisa.

KUNHUNGURA Unhu

Iyo Eko Murmur Analysis Software (EMAS) inotaridza kugunun'una kunogona kuitika mukati memoyo inonzwika kurekodha, uye kana iripo, kungave kugunun'una ikoko kuri systolic kana diastolic, uye hakuna mhosva kana chimiro. Aya haasi ekuongororwa, chete anogona kuwanikwa (s). Kana zvichiratidzwa, iwe unofanirwa kuitisa imwe ongororo kana kugunun'una kwaonekwa. Kugunun'una kutsvaga kunowanzo kurudziro ye echocardiography kana kutumirwa kwenyanzvi. Iyo EMAS inongoshanda chete kana mushandisi akanyorera kune yakakodzera Eko software package, uye iyo package yakavhurwa kuaccount yemushandisi. Kana yangoitwa, iyo EMAS ichaita otomatiki, pakarepo mushure mekunge mushandisi atora rekodha. (Kurekodha kunofanirwa kunge kuine masekonzi mashanu kureba.) Kana kurekodha kwapera, Eko shamwari yenharembozha ichadaidza EMAS uye mhedzisiro yekuongorora icharatidzwa paEko nharembozha isingasviki masekonzi gumi. Hapana kupindira kwemushandisi kunodiwa kutanga, kupedzisa, kana kuratidza kuongorora. Iyo Eko Murmur Analysis Software icharatidza kune mushandisi izvi zvinogoneka mhedzisiro, exampzvimwe zvacho zvinoratidzwa muMufananidzo 1:

• Hunhu husina kunaka hunonzwika
• Hapana kugunun'una kwaonekwa
• Systolic kugunun'una kwakaonekwa
• Diastolic kugunun'una kwakaonekwa
• Innocent kugunun'una akaonekwa
• Kugunun'una kwemaitiro kwakaonekwa

Zvikonzero zvekugunun'una kwe systolic zvinosiyana; uko kugunun'una kunonzwika zvakanyanya kunogona kubatsira pakuongorora. Aortic stenosis, atrial septal defect, uye pulmonic stenosis zvinonzwika zvakanyanya kuruboshwe nekurudyi kumusoro kwemiganhu, nepo mitral regurgitation inonzwika zvakanyanya pamwoyo. Aya maitiro ekugunun'una (pathologic) anogunun'una anorayira kuendeswa kune cardiologist kuti awedzere kuongororwa.1-3 Diastolic kugunun'una, zvakadai seaya anokonzerwa nemitral stenosis kana aortic regurgitation, anonzwika zvakanakisisa pamwoyo wepamusoro uye anewo maitiro (pathologic) uye anopa kuenderera mberi kwekuongorora. , kusanganisira kuendeswa kuna chiremba wemwoyo.3 Innocent systolic kugunun'una, kufanana naStill's kugunun'una, kunowanikwa muvana uye kazhinji kunopera nekukura. Zvichienderana nemamiriro ezvinhu ehutano, vamwe varapi vanogona kutevera varwere ava nekudzokorora auscultation chete.4, 5 Chiremba anofanirwa kutaura kune akakurudzirwa mazano ekutungamirira kwekliniki kuti aone zviito zvakakodzera zvekugunun'una kusina mhosva uye kwemaitiro.

Cherechedza: Kubata kwakaringana kweEko digitaalinen stethoscope (iyo CORE kana DUO) kuderedza kunze ruzha rwekumashure uye rub/kudzvanya kwemaoko kunofanirwa kuitwa.
Cherechedza: Iyo software haizoone mamiriro emoyo asingakonzere kugunun'una kwemoyo.
Cherechedza: Nzvimbo dzese dzekuteerera dzemoyo dzinofanirwa kuongororwa usati waita sarudzo yekutumira.
Cherechedza: Iyi software haiongorore manzwi emapapu.
Cherechedza: Mune mamwe mamiriro ezvinhu, EMAS inogona kuratidza zvisizvo kunyunyuta kwemoyo kunoramba kuripo sesystolic kana diastolic. Nekudaro, kuita sarudzo yekiriniki hakufanirwe kukanganiswa, sezvo mudziyo uchanyatso ratidza kugunun'una kwemoyo kunoramba kuchienderera se "maitiro" 85.6% yenguva inoenderana nekusimbiswa kwedu kwekiriniki.
