  • In your info, when u said u had sinus tach, fi, that's a tracing of the spo2 plotted as a function of time  [ f (time) = SpO2 ] , not your EKG.

  • how do you call a pulse over 100 on a pulse oximeter, then?

  • @bionerd23 What he means is that the image that represents your pulse in that machine is not an EKG. An EKG is based of off electrical pulses, while an oximeter is based off of the SpO2 (as your heart pulses, your SpO2 changes). A pulse over 100 will be greater than 100, but your oxygen saturation percentage obviously will be always less than or equal to 100.

  • @CexsnVida

    well, the pulse oximeter still displays the peripheral pulse (bottom), and as long as the heart is in sinus rhythm, that pulse will be equal to the heart frequency.

  • 0:54 is awesome alarm

  • lol yeah, i should've stolen the machine! :P

    its looovely. i like the R tone as well.
