Iperereza ryuzuye ririmo module yo gupima ogisijeni yamaraso irashobora guhuzwa byihuse hamwe na ogisijeni hamwe na ventilator kugirango bigerweho gupima ogisijeni yamaraso, umuvuduko wa pulse, umuvuduko wubuhumekero, hamwe nubushakashatsi bwa parufe. Irashobora gukoreshwa mumazu, mubitaro, no gukoresha ibitotsi.
Ikoreshwa rya maraso ya ogisijeni ya Narigmed irashobora gukoreshwa mubihe bitandukanye no kubantu bafite imiterere yuruhu rwose, kandi ikoreshwa nabaganga mugupima ogisijeni yamaraso, umuvuduko wimpanuka, umuvuduko wubuhumekero hamwe nubushakashatsi bwa parufe. Byumwihariko byanonosowe kandi binonosorwa kugirango birwanya anti-imikorere na parufe nkeya. Kurugero, mugihe kigenda cyangwa gisanzwe cya 0-4Hz, 0-3cm, ukuri kwuzuye kwa pulse oximeter (SpO2) ni ± 3%, naho gupima neza igipimo cya pulse ni ± 4bpm. Iyo indangagaciro ya hypoperfusion irenze cyangwa ingana na 0,025%, impiswi ya oxyde (SpO2) ni ± 2%, naho igipimo cyo gupima ibipimo ni ± 2bpm.
