“…Exclusion criteria ruled out individuals with lung infections post-COVID-19, those who were mildly ill and treated at home, individuals with any serious post-COVID complications, those with pre-existing pulmonary conditions, patients able to independently clear secretions, and smokers (23). Baseline measurements of oxygen saturation, peak expiratory flow rate, functional capacity, and shortness of breath were recorded using a pulse oximeter (24), a peak expiratory flow meter (25), a six-minute walk test (26), and the modified Borg scale of dyspnea, respectively (27). The modified Borg scale is a numerical score ranging from 0 to 10, commonly used in conjunction with the sixminute walk test.…”

Background: The COVID-19 pandemic has led to significant respiratory complications in affected individuals. Positive Expiratory Pressure (PEP) devices, specifically Acapella and blow bottle devices, have been widely used in respiratory rehabilitation, particularly in patients with pulmonary diseases and post-surgical respiratory complications. However, their efficacy in post COVID-19 patients has been less explored. Objective: This study aimed to compare the effectiveness of Acapella and blow bottle devices in improving oxygen saturation, peak expiratory flow rate, shortness of breath, and six-minute walk distance in post COVID-19 patients. Methods: This randomized clinical trial was conducted at Tehsil hospital Kot Addu over six months. Forty-eight post COVID-19 patients were divided equally into two groups: one group received treatment with the Acapella device, and the other with a blow bottle device. Baseline and post-treatment measurements of oxygen saturation, peak expiratory flow rate, and six-minute walk distance were recorded using a pulse oximeter, peak expiratory flow meter, and six-minute walk test, respectively. Results: On day 1, the Acapella group showed a mean oxygen saturation rank of 20.98 with a sum of ranks of 503.50 (p=0.79), while the Blow Bottle group had a mean rank of 28.02 and a sum of ranks of 672.50. By day 7, the Acapella group's mean rank was 17.31 (sum of ranks = 415.50, p=0.000) compared to the Blow Bottle group's 31.69 (sum of ranks = 760.50). For peak expiratory flow rate, no significant differences were found between the groups at day 1 (Acapella: mean rank = 28.06, sum of ranks = 673.50, p=0.078; Blow Bottle: mean rank = 20.94, sum of ranks = 502.50) and day 7 (Acapella: mean rank = 23.77, sum of ranks = 570.50, p=0.717; Blow Bottle: mean rank = 25.23, sum of ranks = 605.50). Similar trends were observed in the six-minute walk test results. Conclusion: The study found that both Acapella and blow bottle devices effectively improve oxygen saturation in post COVID-19 patients, but do not significantly affect peak expiratory flow rate, shortness of breath, and six-minute walk distance. These findings suggest that while these devices are beneficial for enhancing oxygenation, a more comprehensive respiratory rehabilitation approach is necessary for addressing the full spectrum of respiratory complications in post COVID-19 patients.

Background The global aging population is expanding rapidly and many individuals have a particularly higher risk of malnutrition. Malnutrition can lead to impaired body function, morbidity, and mortality. Meeting nutritional requirements is a key strategy to minimize multiple debilitating adverse outcomes associated with malnutrition in the elderly. Oral nutritional supplements (ONS) have been widely used as a dietary intervention for malnutrition in older adults. These supplements provide additional nutrients and calories to support nutritional requirements and have been shown to improve nutritional status, physical function, and quality of life in malnourished older adults. Methods This is an open-label, randomized controlled, parallel-group study including 50 institutionalized older adults (aged > 60 years) with malnutrition or at risk of malnutrition, living in a selected elderly care institution in Colombo, Sri Lanka. The aim is to assess improvement in healthy body weight gain and body composition in older adults with malnutrition at risk of malnutrition by using an ONS. Older adults will be screened for malnutrition using the Mini Nutrition Assessment (MNA) tool and eligible participants randomized using the simple random sampling technique to intervention and control groups (1:1 allocation ratio). The intervention group will consume 200 mL of ONS before bed continuously for 12 weeks. The primary outcome is the percentage who achieved at least 5% weight gain in the intervention group compared to the control group. Nutritional status (anthropometric, biochemical, clinical, and dietary), body composition (dual-energy X-ray absorptiometry), frailty, functional capacity (hand grip strength, knee extension, and Barthel index) cognitive status (Montreal Cognitive Assessment), and physical activity will be assessed as secondary outcomes at baseline and at the end of the 12-week intervention. Some measurements (anthropometry, dietary, and functional assessments) will also be performed at the end of the 4th week. Data will be analyzed using SPSS V-23. Discussion This study will determine whether the use of an ONS is effective in promoting healthy weight gain in older adults with malnutrition or at risk of malnutrition. In addition, investigating the impact of an ONS on multiple outcomes via clinical, nutritional, functional, and cognitive function will provide a more comprehensive understanding of the potential benefits of these supplements.

“…Peak flow meter is a lung function test tool that is simple, compact, easy to carry, cheap and easy to use to check PEFR (Patil et al, 2020). Thus, routine and periodic checks on lung function should be carried out in asthma patients, so that this can be an effort to prevent recurrent asthma attacks and ventilation problems in the lungs.…”

Background: Asthma is a prevalent, chronic, and varied condition in which most people experience dyspnea, wheezing, chest tightness, and coughing due to reversible airway obstruction, airway inflammation, and bronchial hyperreactivity. cause the quality of life to diminish. The breathing method known as diaphragmatic breathing is tailored to the needs of asthmatics. During a deep inhale, a breathing method called diaphragmatic breathing relaxes the respiratory muscles. Objective: To determine the effect of diaphragmatic breathing exercises on peak expiratory flow rate (PEFR) patients with bronchial asthma. Method: This type of research is quasi-experimental with a one-group pre-test and post-test design. The sampling method used purposive sampling with 15 respondents. The PEFR measurement instrument uses a peak flow meter. Data were analyzed univariately and bivariately using the paired T-Test. Results: The average PEFR value before and after diaphragmatic breathing exercise therapy was 246.67 L/minute and 300 L/minute. There was a significant difference in PEFR before and after being given diaphragmatic breathing exercise therapy with an increase in PEFR value of 53.33 L/minute (p-value 0.00). Conclusion: Diaphragmatic breathing exercises have a significant influence on PEFR values in bronchial asthma patients
