Demonstration of finger sympathetic nerve activity decrease post exercise, finger vessels open to move more blood through.

Finger microvascular testing using the Vagis ring on each hand during finger tip ice bath immersion for 5 min. The large decrease in pulse wave height in the room temp control hand shows the brainstem reflex. Might this reflex be dysfunctional in MECFS or LC? @ImmunoFever

Comparison between a run causing mild PEM and a run not causing mild PEM (not yet anyway). Figures are run comparison data, post run vascular tone gradual return to baseline, and sleep analysis pre run. This is just a first look at the data. @RenegadeRes

Reactive Hyperaemia Part II. Supine with a ring on each hand. Change in finger blood volume/oxygen (Fig.1), pulse wave amplitude (Fig.2), Stefanovska bands (Fig.3), before/during/after cuff applied 5 min at 230 mmHg. @ImmunoFever

Two Vagis rings, one on each hand, overnight. Finger pulse wave amplitude split into Stefanovska vascular bands, left vs right in light sleep. Central rhythms match (r = 0.89). The Endothelial-NO band is the most hand-specific: a local microvascular signal. Research use only.

I compared the Vagis ring pulse interval (RR) data to the Polar H10 single lead ECG for my entire sleep last night and for a 10 min segment of low movement. Across the night correlation was r=0.996, error of 3.4 ms, bias of 0.

Playback video of my breathwork session from this morning. Watch how the HRV spectrum tightens around the 0.1 Hz marker which is exactly 6 breaths/min, resonance frequency.

I wish I knew how this happened last night (Oct15), I’ve never seen this level of vasomotion in my deep sleep before. Oct9 is an average night. Breathing and HR stable (Vagis), SpO2 stable (Oxyring) so this is not sleep apnea. This is most likely brain cleaning vasomotion.

I think this is a miss by Apple Watch. My sleep last night. Vagis/Apple/Oxyring segment/Vagis. Good alignment between Vagis and Apple except for 2-3. Apple shows awake here but I was not and Oxyring shows no motion and steady HR between about 2:20 to 3:00.

Autonomic Multi-Mode Agent (AMMA) comparison analysis between 2 subjects. Heart Rate, RMSSD, Vascular Tone during Deep Sleep, Breathwork, and Quick Check. @RenegadeRes

The first Autonomic Multi-Mode Agent (AMMA) metric provided by Vagis.health app. RMSSD compared across 3 different ANS assessment modes. I can finally discuss and share AMMA data now since I filed the provisional patent yesterday.

Vagis app can search your genomic VCF file that’s saved on your phone. I was researching the SCGB1D2 gene and looked up 2 related rsID’s in Vagis. Looks like I am het for both variants putting me in intermediate genetic risk for Lyme disease. 🦠 @ImmunoFever

A couple gins while making the turkey yesterday (Canada Thanksgiving) and some wine with dinner and yeah my sleep data will show it. Average HR up 10 bpm, 155 min HR cycling, HR VLF way down, breathing rate up. However, quick check data looks fine this morning.

From Vagis ring, 10 min deep sleep segments from a 14yr male athlete - Max - and his old man 52 yr father, me. Very clear pulse wave amplitude dips for Max not related to HR, breathing, or motion. This is vasomotion that cleans the brain fluid.
