Fig. 4: Respiratory monitoring of a patient over a 14-h period.
From: Non-contact physiological monitoring of post-operative patients in the intensive care unit
The video camera-derived estimates (in red) are compared against the reference values provided by the bedside monitoring equipment (in black). Periods during which the privacy blind was drawn, and thus video monitoring was interrupted due an obstructed camera view of the patient, are shown in the bottom panel. Sample frames from the video camera recording during invasive respiratory support and after extubation are shown as inserts at t = 22:15 and t = 09:15.
