A New Approach to Non-Invasive Microcirculation Monitoring: Quantifying Capillary Refill Time Using Oximetric Pulse Waves.

Sensors (Basel)

January 2025

Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University, 168 Litang Road, Changping District, Beijing 102218, China.

(1) Background: To develop a novel capillary refill time measurement system and evaluate its reliability and reproducibility. (2) Methods: Firstly, the utilization of electromagnetic pressure technology facilitates the automatic compression and instantaneous release of the finger. Secondly, the employment of pressure sensing technology and photoelectric volumetric pulse wave analysis technology enables the dynamic monitoring of blood flow in distal tissues.

 Expansion sphincter pharyngoplasty has been shown to be a good alternative to continuous pressure devices in patients with moderate to severe obstructive sleep apnea. On the other hand, drug-induced sleep endoscopy provides information on the pattern of collapse in obstructive sleep apnea, although it is unclear whether this information improves the surgical outcomes.  To evaluate the success rate obtained when performing expansion sphincter pharyngoplasty on a group of patients diagnosed with moderate to severe obstructive sleep apnea who were not previously selected by drug-induced sleep endoscopy.

Sedation of high-risk patients is a relevant issue in interventional endoscopy. This is especially because standard oximetric monitors display only hypoxia and not the preceding hypercapnia. Therefore, the question arises whether use of a nasal positive airway pressure (nPAP) system can decrease the rate of sedation-associated events.
