Inzwa Yokucindezela ye-LMEC-29 kanye Nokulinganiswa Kwezinga Lokushaya Kwenhliziyo kanye Nomfutho Wegazi Isithombe Esifakiwe

Inzwa Yokucindezela ye-LMEC-29 kanye Nokulinganiswa Kwezinga Lokushaya Kwenhliziyo Nokucindezela Kwegazi

Incazelo emfushane:

Izici zenzwa yokucindezela kanye nesilinganiso senhliziyo yomuntu, ithuluzi lokuhlola ukulinganisa umfutho wegazi liyithuluzi lokuhlola ngokomzimba lokufundisa kochwepheshe bezokwelapha. Lisekelwe ezidingweni zokufundisa zokuhlolwa okungezona ngokomzimba emakolishi nasemanyuvesi ezweni lonke ukuze kufundwe futhi kuqondwe kahle ukulinganisa izici kanye nokusetshenziswa kwenzwa yokucindezela igesi, ikakhulukazi ukuhlolwa kuhlanganiswe eduze nokuqukethwe kwesilinganiso senhliziyo yomuntu kanye nokulinganisa umfutho wegazi kochwepheshe bezokwelapha.

Imisebenzi

1. Qonda isimiso sokusebenza senzwa yokucindezela kwegesi bese uhlola izici zayo.

2. Sebenzisa inzwa yokucindezela kwegesi, i-amplifier kanye ne-voltmeter yedijithali ukwakha i-digital pressure gauge bese uyilinganisa nge-standard pointer pressure gauge.

3. Qonda isimiso sokulinganisa izinga lokushaya kwenhliziyo yomuntu kanye nomfutho wegazi, sebenzisa inzwa yokushaya kwenhliziyo ukukala isimo se-pulse wave kanye nemvamisa yokushaya kwenhliziyo, bese usebenzisa i-digital pressure gauge eyakhelwe ukukala umfutho wegazi womuntu.

4. Qinisekisa umthetho kaBoyle wegesi efanele. (Ongakukhetha)

5. Sebenzisa i-oscilloscope yokuskena kancane kancane (kudingeka ithengwe ngokwehlukana) ukuze ubone isimo se-pulse yomzimba futhi uhlaziye ukushaya kwenhliziyo, ulinganise izinga lokushaya kwenhliziyo, umfutho wegazi kanye nezinye izilinganiso. (Ongakukhetha)
