Key result
Dynamic pulse-oximetry shows promise for telemonitoring and managing chronic cardio-respiratory diseases.
Why the study?
Current models for diagnosing and monitoring chronic respiratory and cardiovascular diseases lead to late interventions and high costs, prompting interest in expanding telemonitoring and pulse-oximeter use outside hospital settings.
Expanding the use of pulse oximetry to continuous 24-hour dynamic monitoring could improve the out-of-hospital management of chronic cardiac and respiratory diseases.
May support telemonitoring exploration in chronic cardio-respiratory disease without changing practice; leaves open prospective trial validation.
Respiratory and cardio-vascular chronic diseases are among the most common noncommunicable diseases (NCDs) worldwide, accounting for a large portion of health-care costs in terms of mortality and disability. Their prevalence is expected to rise further in the coming years as the population ages. The current model of care for diagnosing and monitoring NCDs is out of date because it results in late medical interventions and/or an unfavourable cost-effectiveness balance based on reported symptoms and subsequent inpatient tests and treatments. Health projects and programs are being implemented in an attempt to move the time of an NCD's diagnosis, as well as its monitoring and follow up, out of hospital settings and as close to real life as possible, with the goal of benefiting both patients' quality of life and health system budgets. Following the SARS-CoV-2 pandemic, this implementation received additional impetus. Pulseoximeters (POs) are currently used in a variety of clinical settings, but they can also aid in the telemonitoring of certain patients. POs that can measure activities as well as pulse rate and oxygen saturation as proxies of cardio-vascular and respiratory function are now being introduced to the market. To obtain these data, the devices must be absolutely reliable, that is, accurate and precise, and capable of recording for a long enough period of time to allow for diagnosis. This paper is a review of current pulse-oximetry (POy) use, with the goal of investigating how its current use can be expanded to manage not only cardio-respiratory NCDs, but also acute emergencies with telemonitoring when hospitalization is not required but the patients' situation is debatable. Newly designed devices, both "consumer" and "professional," will be scrutinized, particularly those capable of continuously recording vital parameters on a 24-hour basis and coupling them with daily activities, a practice known as dynamic pulse-oximetry.

Nardini et al. (2023) conducted a review in Chronic cardiac and respiratory diseases. Dynamic pulse-oximetry was evaluated. Dynamic pulse-oximetry, capable of continuously recording vital parameters and daily activities, offers a promising approach for the telemonitoring and management of chronic cardio-respiratory diseases.
