Respiratory monitoring of nonintubated patients in nonoperating room settings: old and new technologies.

Published: August 2022

Purpose Of Review: Postoperative 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 Findings: Technical 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.

Summary: Respiratory 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.

Introduction: Telemedicine is a health service that provides diagnosis, treatment evaluation, preventive medicine by using information and communication technologies between distant locations and aims to improve the health of the individuals and society. Social restrictions were applied during the pandemic process caused by coronavirus disease-2019 due to the virus called severe acute respiratory syndrome coronavirus-2 which emerged in late 2019. Through remote communication and information technologies in the followup of asthma patients, there is a need for studies on the effectiveness of using telemedicine methods was seen.

Introduction: The government's role in influencing policies related to Coronavirus disease 2019 (COVID-19) vaccine distribution and handwashing practices is essential in controlling the spread of severe acute respiratory syndrome coronavirus 2.

Methods: This study aimed to systematically review published studies to explore the influence of government policies on handwashing and vaccine uptake in Kenya, Uganda and Tanzania to prevent and control COVID-19. A comprehensive search strategy was applied across three databases, and eligibility was determined using strict inclusion and exclusion criteria.

Population-level vaccination with newly developed vaccines to respond to the COVID-19 pandemic created a need to monitor vaccine effectiveness (VE) in the context of emerging SARS-CoV-2 variants and changing epidemiology. WHO and partners launched the African Region Monitoring Vaccine Effectiveness (AFRO-MoVE) Network in March 2021 to assess the performance of COVID-19 vaccines in real-world conditions in Africa. The Network aimed to facilitate and support comparable COVID-19 vaccine effectiveness studies in the African region, to provide a platform of scientific expertise and infrastructure, encourage the use of robust similar study designs to enable pooling to produce regional VE estimates and to build a sustainable network of hospitals, institutions, and experts to evaluate vaccines against pandemic and endemic respiratory pathogens.

Article Synopsis
  • Aging leads to physiological changes and increased disease vulnerability, culminating in higher mortality rates as individuals get older.
  • Regular physical activity (PA) and exercise can counteract aging effects, improve health span, and reduce the risk of chronic diseases such as heart disease and cancer.
  • Personalized exercise plans, including various forms of training like aerobic and resistance exercises, are essential for maintaining health and functionality in older adults, particularly those with age-related issues.
