Fingertip Pulse Oximeter Nyeem Ntawv

Nws tuaj yeem muaj ob lossis ntau qhov kev nyeem ntawv, uas tau tshwm sim ntawm qhov screen ntawm Oximeter Fingertip. Lawv yog raws li nram no

1. Oxygen Saturation (SPO2)

SPO2=(tag nrho no. ntawm oxyhemoglobin/tag nrho no. ntawm hemoglobin) * 100. Hauv RBC, yog tias muaj 8 hemoglobin molecules khi rau cov pa tawm ntawm 10 molecules ces txhais tau tias SPO2 yog 80%.

SPO2 Status Remarks

94% txog 99% Ib txwm Tsis tas yuav txhawj xeeb

90% mus rau 94% Tej zaum yuav yog tus neeg mob ib txwm Tham nrog kws kho mob

Hauv qab 90% Tus neeg mob tseem ceeb yuav tsum tau muaj oxygen ntxiv

2. Oximeter Fingertip tshuab tuaj yeem kuaj lub plawv dhia

Nws qhia txog tus naj npawb ntawm kev ntaus lub plawv ua hauv ib feeb. Lub plawv dhia li ib txwm nyob ntawm 60 mus rau 100 neeg ntaus ib feeb (BPM).

3. Perfusion Index

Perfusion Index txhais tau tias yog qhov piv ntawm cov ntshav pulsatile ntws mus rau cov ntshav uas tsis yog pulsatile ntws hauv peb cov ntaub so ntswg. Nyob rau hauv lwm yam lus, ib tug siab perfusion Performance index txhais tau hais tias ib tug zoo ntawm oxygenated ntshav los ntawm cov hlab ntsha thiab vice versa.

Perfusion Performance index ntawm 0-5 tuaj yeem suav tias yog tus nqi qis. Ib yam li ntawd, saum toj no 5 tej zaum yuav raug suav hais tias yog tus nqi zoo ntawm perfusion Performance index.
