Oxi-W system is intended for use:
To spot check or monitor Oxygen saturation of arterial hemoglobin (SpO2%) and pulse rate.
To analyze the pulse waveform (Photoplethysmography or PTG) provided by the oximeter. It only provides mathematical analysis of the input of the PTG using the first and second derivatives of the PTG values related to the microvascular condition.
To analyze the basic rhythms of the NN or RR intervals in heart rate from the PTG, both in the time domain and in the frequency domain (short time 5 minutes). It only provides mathematical analysis of the heart rate variability values related to the autonomic nervous system function.
The system only provides mathematical analysis of input PTG values. It is practitioner to make proper judgement based on these values.
The software provides a visual alarm for the values of the heart rate and/or SpO2 percent out of the normal range and for the bad quality signal transmission.
The data are stored in PC in the Backup system of the Oxi-W software. The device is intended use only for adult subjects (> 20 years old) This Oximeter is intended to be used in spot-checking (5 minutes).
The device is intended for use in licensed practitioner’s office
This device is no intended to be used at home, in hospital or out-of-hospital transport
The device is not intended for use in support life and not for continuously monitoring
The system will be used by practitioner.
Indications for use as stated in the FDA summary.
