“…Biochemical tests are used to diagnose the condition; medications are provided as therapy, and the use of overdosing by risk-averse practitioners is every day [ 9 ]. Continuous vital sign monitoring with tissue genetically programmed devices and, in some cases, syringe pressure sensors put into the bloodstream is the standard clinical treatment in neonatal Intelligent Medical Care (IMC) [ 10 ]. Spirometry is the most basic test, and this test assesses the airways' capacity to retain air.…”

Neonatal Bronchopulmonary Bedside Photography (NBBP) evaluates the consumption of lung magnetic resonance imaging as a replacement for bedside imaging in diagnosing infant pneumonia. In premature baby respiratory support, Neonatal Bronchopulmonary (NB) is one of the most dangerous consequences of accurate diagnosis that impact health alternatives once steroids are administered. Infants may experience eating issues and vomit if their condition is bad enough; lower birth weight, younger gestational age, and extensive breathing tube damage are the most frequently established risk factors as a component of a neonatal habitat. This paper introduces the Intelligent Medical Care (IMC) for Neonatal Bronchopulmonary Bedside Photography (NBBP), which enhances various preventive efforts such as prenatal steroid therapy. Because of many prenatal and postnatal variables, growth hormone and diet nutrients influence alveolar and vascular development. For the future prevention of NB, it is more likely that a combination of different therapies working on diverse causal pathways would be beneficial. This research in NBBP-IMC technology that enhances prenatal care medicines are the most excellent and effective treatments for all these neonates throughout the decades. As a result, premature babies at risk for NB may benefit from the findings of this research, which experts anticipate can inspire further studies in the area. The purpose of this paper is to emphasize the work performed to improve respiratory outcomes for babies at risk of NB and to place this work in perspective with relevant research currently being conducted simultaneously.

“…They can be used as remarkable solutions in different application fields, especially in the scenarios where unobtrusive methods are required (e.g., hospital waiting rooms, tele-monitoring, neonatal intensive care units). Some examples in clinical settings include Doppler radar [ 12 ], depth sensors [ 13 ], laser vibrometry [ 14 ], and RGB cameras [ 13 , 15 , 16 ]. Additionally, different non-contact techniques including thermal cameras, video cameras, and radar sensors can be used in the automotive environment, or even for monitoring cognitive load and emotional stress in computer workers [ 17 ].…”

Respiratory monitoring is receiving growing interest in different fields of use, ranging from healthcare to occupational settings. Only recently, non-contact measuring systems have been developed to measure the respiratory rate (fR) over time, even in unconstrained environments. Promising methods rely on the analysis of video-frames features recorded from cameras. In this work, a low-cost and unobtrusive measuring system for respiratory pattern monitoring based on the analysis of RGB images recorded from a consumer-grade camera is proposed. The system allows (i) the automatized tracking of the chest movements caused by breathing, (ii) the extraction of the breathing signal from images with methods based on optical flow (FO) and RGB analysis, (iii) the elimination of breathing-unrelated events from the signal, (iv) the identification of possible apneas and, (v) the calculation of fR value every second. Unlike most of the work in the literature, the performances of the system have been tested in an unstructured environment considering user-camera distance and user posture as influencing factors. A total of 24 healthy volunteers were enrolled for the validation tests. Better performances were obtained when the users were in sitting position. FO method outperforms in all conditions. In the fR range 6 to 60 breaths/min (bpm), the FO allows measuring fR values with bias of −0.03 ± 1.38 bpm and −0.02 ± 1.92 bpm when compared to a reference wearable system with the user at 2 and 0.5 m from the camera, respectively.

“…Noncontact monitoring has the advantage of being completely unobtrusive. Sensing the rhythmic movement of respiration is possible through sensors integrated in the bed [46] as well as remote sensing through camera [47] and radar [48]. Although not directly applicable for postanaesthesia care, these technologies give an insight into how respiratory monitoring is moving away from critical care and into the general ward and in people's homes.…”

Purpose of reviewPostoperative mortality in the 30 days after surgery remains disturbingly high. Inadequate, intermittent and incomplete monitoring of vital signs in the nonoperating room environment is common practice. The rise of nonoperating room anaesthesia and sedation outside the operating room has highlighted the need to develop new and robust methods of portable continuous respiratory monitoring. This review provides a summary of old and new technologies in this environment. Recent findingsTechnical advances have made possible the utilization of established monitoring to extrapolate respiratory rate, the increased availability and user friendliness of side stream capnography and the advent of other innovative systems. The use of aggregate signals wherein different modalities compensate for individual shortcomings seem to provide a reliable and artefact-free system. SummaryRespiratory monitoring is required in several situations and patient categories outside the operating room. The chosen modality must be able to detect respiratory compromise in a timely and accurate manner. Combing several modalities in a nonobtrusive, nontethered system and having an integrated output seems to give a reliable and responsive signal.
