Article Synopsis
  • The inhalation-exhalation (I:E) ratio is a key indicator of respiratory health, and this study explores a non-contact method using a depth sensing camera to measure it.
  • Healthy volunteers produced a range of I:E ratios, and the data was collected and analyzed in real-time, leading to accurate measurements similar to traditional spirometry.
  • This non-contact approach could be a valuable tool for ongoing monitoring of respiratory conditions like COPD and asthma, allowing clinicians to track patient status without requiring physical devices.

Study Objectives: A non-intrusive sleep monitoring technology based on the data from a commercially available depth sensing camera has been utilized for respiratory monitoring and shown to have good performance in assessing respiratory rates across a range of rates. This non-contact, or , technology allows continuous respiratory monitoring without attaching probes to the patient. We have noticed a strikingly similar morphology between the touchless flow signal (NCM) and the flow signal derived using the chest and abdomen respiratory inductance plethysmography (RIP) bands.

Introduction: Respiratory rate (RR) is a crucial vital sign in patient monitoring and is often the best marker of the deterioration of a sick patient. It can be used to help diagnose numerous medical conditions and has been demonstrated to be an independent predictor of patient outcomes in various critical care settings and is incorporated in many clinical early warning scores. Here, we report on the performance of depth-camera-based system for the noncontact monitoring of RR during a ramped RR protocol.

Purpose: This study aims to evaluate the real-world efficacy and safety profile of fluocinolone acetonide (FAc) implants for the treatment of non-infectious uveitis (NIU).

Methods: A retrospective, observational study was conducted at Moorfields Eye Hospital, London, involving patients who received FAc 0.19 mg implants (Iluvien®) for NIU.

Two fruit fly (Diptera: Tephritidae) species of economic importance: Karsch and De Meyer, Mwatawala & Virgilio are present in South Africa. The two species were considered as one species prior to 2016, but were subsequently separated. In this study, the distribution and abundance of the two species were quantified in seven provinces in South Africa through trapping with Enriched Ginger Oil as an attractant.
