Overview

The COVID-19 pandemic has emerged as the most significant public health crisis of the 21st century. As of the end of January 2023, global confirmed cases have exceeded 670 million, with a domestic cumulative total of 10.24 million cases, including occurrences of reinfection. Beyond acute symptoms following infection, patients and society face the challenge of long-term complications associated with COVID-19. Termed 'Post COVID-19 condition' or 'Long COVID' by the World Health Organization (WHO), this encompasses symptoms appearing within three months of the initial infection. Symptoms of Long COVID reveal chronic damage inflicted by the virus on multiple organ systems, including fatigue, cognitive impairment, chest tightness, palpitations, difficulty breathing, and depression. Despite continuous efforts by healthcare professionals to find suitable treatments, no medication has been confirmed to effectively prevent or reduce post-COVID-19 sequelae. These health issues impose significant burdens and disturbances on patients' quality of life, economies, and societies.

According to the Ministry of Health and Welfare's report on the top 10 causes of death in the 111th year, aside from the marked increase in COVID-19 cases, there have been significant increases in hypertensive diseases, Cardiac diseases, and diabetes .Therefore, addressing the post-COVID-19 sequelae among chronic disease patients is an essential global health issue in the post-pandemic era. Current research indicates that respiratory training is safe and effective in improving the exercise capacity, lung function, and alleviating respiratory difficulties in COVID-19 recovered patients. The impact of respiratory training on patients' respiratory and physical function remains uncertain, especially considering that many present-day infections are among non-hospitalized individuals with mild symptoms. Thus, exploring simple and effective respiratory training methods to reduce COVID-19's long-term impact on patients warrants continuous investigation. Therefore, this study will employ Incentive spirometer-based respiratory training to assist COVID-19 patients who has diabetes, hypertensive disease, or cardiac disease in respiratory training. Data collection before and after the intervention will involve oxygen demand, blood parameters, the post-COVID-19 Functional Status scale (PCFS scale), and lung function indices, to investigate and evaluate the effectiveness of intervention respiratory training in improving Long COVID symptoms.

Incentive Spirometer respiratory trainingBEHAVIORAL

The incentive spirometer is a handheld mechanical breathing device that uses a one-way valve to prevent exhalation. It consists of a corrugated tube and a nozzle connected to three consecutive plastic chambers, each containing a ball. The external chambers are marked with the minimum flow required to raise the ball internally. The ball rises when the patient performs slow, deep breathing through the nozzle. If the patient breathes too quickly, the balls in the chambers rise to the top, and if breathing is too slow, the balls fall to the bottom. The number of increasing balls measures the volume of inhaled air. When all three balls reach the top of the chambers, the patient's flow rate can reach 1200 ml/s. After the patient has maximized their inhalation, they are asked to hold the balls in the same position for more than 3 sec.
