Talk:Photoplethysmogram

I
I had started a page under photoplethysmogram. What convinced me to change to the Photoplethysmograph stub was that the term plethysmograph is much more prevalent in the medical literature than plethysmogram.

This page is being constructed with input from the Photoplethysmography@yahoogroups.com group of researchers.--Spl4 04:23, 9 November 2006 (UTC)

Hey there Spl4. These look like some great additions to the article! I think it could use some more simplified language though, especially for the introductory paragraph (the average reader probably doesn't know what the "pulsatile component of the cardiac cycle" means). If you'd rather I do it, that's fine. johnpseudo 05:03, 9 November 2006 (UTC)

Hi, the time scale of the first picture is definitely wrong. I'll try to make a better one as I have some good raw datas from a PPG-device I built. (Jfiala (talk) 10:10, 7 March 2008 (UTC))

Name
I would heavily suggest to change the title to Photoplethysmogram. The use of the word plethysmograph/plethysmogram is indeed not consistent in literature. Maybe the word plethysmograph is more prevalent in the medical literature, but in literature focussed on biomedical engineering, pulse oximetry, pulse wave analysis etc. the word plethysmogram is prevalently used.

The original meaning for plethysmograph is the instrument to measure the variations of volumes, according to Oxford dictionary and Merriam-Webster dictionary. Merriam-Webster describes the tracing made by a plethysmograph as a "plethysmogram".

As the use of the word photoplethysmograph/photoplethysmogram is not consistent in literature. The origin is unequivocal. To avoid confusion in the meaning of the word photoplethysmograph, the article name has to be changed to photoplethysmogram and a new entry has to be generated for photoplethysmograph, referring to this article.

The result of the move request was: pages moved per request. There was some old article history at Photoplethysmogram, which I moved to Photoplethysmograph. Those edits, from 2006, can now be found in the history there. - GTBacchus(talk) 13:44, 17 August 2011 (UTC)

– Disambiguation is required between the word photoplethysmogram, describing the signal, and photoplethysmograph, describing the measurement device - All content listed on the current "Photoplethysmograph" entry describes the signal, a separate page for the measurement device has been created.

Errors
Section "Monitoring Respiration" gives an incorrect definition of sinus arrhythmia, which is actually the variation in heart rate through the respiratory cycle, not the variation of stroke volume.

Section "Monitoring Respiration" does not actually describe any use of the plethform176.25.136.178 (talk) 08:43, 4 February 2013 (UTC)

The x-axis of the figure (time in seconds) seems wrong; that would mean about 4 heartbeats in 200 seconds... — Preceding unsigned comment added by 95.98.235.235 (talk) 10:09, 4 April 2024 (UTC)
