デジタル指酸素濃度計ポータブル電子LEDディスプレイ指先パルス酸素飽和モニター

It is very powerful to detect the suffocation of air through the oximeter and hold it for about 20 seconds. The oximeter index begins to decline, indicating that the flow of blood oxygen to the fingertips takes about 20 seconds. It basically meets the standard of 20 seconds a week for heart blood circulation. After breathing, you hold your breath for 55 seconds. After the oximeter index starts to drop, the blood oxygen content drops to 92 after holding the breath for two minutes. The lung capacity of the ordinary house can maintain the saturation of the blood oxygen content for 35 seconds. I think this thing is useful for practicing free diving. You old people hahaha

Ottimo strumento di misura dell'ossigeno (che in questo periodo di "covid" è molto importante!),Misura anche i battiti del cuore e la frequenza respiratoria,inoltre ha una importante misurazione:puo' misurare le "apnee notturne",cioe
tenendolo al "dito" durante la notte (ciclo minimo di 8 Ore) ti misura (memorizzandolo in un "grafico")se durante il "Sonno" hai avuto un'ipossia.Molto bene anche la spedizione arrivata in tempi brevi.

Although I waited nearly a month, I can understand that the situation is very bad. I received the package today, which is the same as the seller ’s description.
