Hi,  
I wanted to ask is there a way in the SEdatarequest in python to get the data for OxygenSaturation and RespirationRate on generating the waveforms. Because I manage for the ECG and ArterialPressure but was wondering if those two are possible as well?

```auto
  self.data_requests = [
            # Numeric value
            SEDataRequest.create_physiology_request("HeartRate", unit=FrequencyUnit.Per_min),
            SEDataRequest.create_physiology_request("SystolicArterialPressure", unit=PressureUnit.mmHg),
            SEDataRequest.create_physiology_request("DiastolicArterialPressure", unit=PressureUnit.mmHg),
            SEDataRequest.create_physiology_request("RespirationRate", unit=FrequencyUnit.Per_min),
            SEDataRequest.create_physiology_request("OxygenSaturation"),
            SEDataRequest.create_physiology_request("CoreTemperature", unit=TemperatureUnit.C),

            # Waveforms
            SEDataRequest.create_ecg_request("Lead3ElectricPotential"),
            SEDataRequest.create_physiology_request("ArterialPressure", unit=PressureUnit.mmHg),
        ]
 self.data_req_mgr = SEDataRequestManager(self.data_requests)

```

Our vitals monitor uses the end tidal CO2 partial pressure for the yellow respiration related waveform
