Narigmed's watch oximeter iri nyore kupfeka uye kuyera. Kunyanya, tekinoroji yeokisijeni yeropa muchigadzirwa inogona kushandiswa kune akasiyana mamiriro uye vanhu vemarudzi ese eganda, uye inoshandiswa navanachiremba kuyera ropa reokisijeni, pulse rate, kufema kwekufema uye perfusion index. Kunyanya optimized uye yakagadziridzwa anti-kufamba uye yakaderera perfusion kuita. Semuenzaniso, pasi pekufamba kana nguva dzose kufamba kwe0-4Hz, 0-3cm, kururamisa kwepulse oximetry (SpO2) ndeye ± 3%, uye kuyerwa kwechiyero chekuputika kwemhepo ndeye ± 4bpm. Kana iyo hypoperfusion index yakakura kudarika kana yakaenzana ne0.025%, iyo pulse oximetry (SpO2) yakarurama ndeye ± 2%, uye chiyero chekuyera kuyerwa kwe ± 2bpm.
