[29/06, 11:32] : Morning journal club around a local work from IIIT Hyderabad 

Rolling the ball:

Wondering aloud on the methodology and to quote,

"Multiple sets of readings were then taken by treating physicians, based on subject availability. 

Initially, readings 

were acquired using the manual sphygmomanometer 

method for a duration of 5 minutes, with the results 

recorded. 

Subsequently, readings for the same subjects 

were obtained using the ProRithm device following the 

same protocol. 

The collected readings were analyzed and 

uploaded for algorithm readability assessment. 

Final analysis occurred after all subjects completed a minimum 

of three sets of readings.

Questions:

What was the interval between each set of three readings? 

What was the interval between the manual readings and the PPG readings?

Ethics approval was from

St Theresa’s Hospital, Erragadda?

[29/06, 11:29] First author Medical Oncology: The intervals are 15 min

[29/06, 11:29] First author Medical Oncology: There is no practical gap between manual and prorithm(we note down the time of manual reading and matched with prorithm reading)

[29/06, 11:35] ALLM: Oh you mean when the patient was having his manual reading done he was already connected to the PPG device and it was also collecting the signals at the same time?

[29/06, 11:37] First author Medical Oncology: Yes

[29/06, 11:37] First author Medical Oncology: That's right sir

[29/06, 11:53] Rakesh Biswas: Another question asked by one of our group members from NJ

What is the range of systolic and diastolic bps recorded?

[29/06, 11:54] Deep Facts PPG Bp Monitoring: Systolic Range: 100 to 170

Diastolic Range: 60 to 90

[29/06, 11:55] Deep Facts PPG Bp Monitoring: Ranges can be improved based on the training the model.

[29/06, 11:55] Deep Facts PPG Bp Monitoring: Important is the corner cases

[29/06, 11:59] NJ: So, the pressures were measured in different arms then?

[29/06, 12:02] Deep Facts PPG Bp Monitoring: Sir, Manual measurement is taken from left hand and proRithm measurement is taken from Chest.

 [29/06, 12:02] Deep Facts PPG Bp Monitoring: 

Sir, Manual measurement is taken from left hand and proRithm measurement is taken from Chest.

[29/06, 12:08] Deep Facts PPG Bp Monitoring: Duration of the test is as follows,

1.⁠ ⁠Connect proRithm Device to Patient, Run the test for 5 minutes

2.⁠ ⁠⁠Parallel we have taken reading manually from Sphgmomanometer

3.⁠ ⁠⁠Test was continued for 3 minutes with gap of 10 minutes

[29/06, 12:08] Deep Facts PPG Bp Monitoring: Total proRithm Test: 5 Minutes each for 3 Times (Total 15 Minutes) for each patient.

[29/06, 12:10] Deep Facts PPG Bp Monitoring: Here is the demo video of the device (Please note this video is one year old)
