Aim: To determine frequency of undiagnosed hypoxia in pts which was medically sick admitted in chest wards. Study design: Cross-sectional. Place and duration of study: Department of Medicine, Social Security Hospital, Multan Road Lahore from 1st January 2020 to 30th June 2020. Methodology: Two hundred and ninety patients were included in this study. Patients detailed demographics age, sex, and body mass index were recorded after taking written consent and admitted in chest wards. Presented patients were aged between 20-70 years. Pulse oximeter was used to measure the oxygen saturation levels. Mean time of hospitalization was also measured. Results: There were 170(60%) males and 120(40%) females with mean age of the patients were 40.78±18.64 years. Mean BMI was 27.78±12.64 kg/m2. Majority of the patients 160(55.17%) were from the age group 35-70 years. Calculated oxygen saturation rate was 91.98±9.42% in which minimum rate was 80% and the maximum rate was 105%. Mean heart rate was 92.96±19.20 per minute. Patients were admitted due to tuberculosis were 102(35.17%), patients with chronic pulmonary disease were 70 (24.17%), patients with pleural effusion were 30(10.34%) and the patients of asthma were 20(6.9%). In this study hypoxia was observed in 44 (15.17%) patients and was absent in 246 (84.83%) patients. Conclusion: The frequency of hypoxia was most prevalent in male patients with increasing age as compared to females and in chronic obstructive pulmonary disease patients, it was observed more commonly.

Sit To Stand

Background: Chronic obstructive pulmonary disease (COPD) is frequently associated with exertional oxygen desaturation, which may be evaluated using the 6-minute walking test (6MWT). However, it is a time-consuming test. The 1-minute sit-to-stand test (1STST) is a simpler test, already used to evaluate the functional status. The aim of this study was to compare the 1STST to the 6MWT in the evaluation of exertional desaturation. Methods: This was a cross-sectional study including 30 stable COPD patients who performed the 6MWT and 1STST on the same day. Six-minute walking distance (6MWD), number of 1STST repetitions (1STSTr), and cardiorespiratory parameters were recorded. Results: A significant correlation was found between the 6MWD and the number of 1STSTr (r = 0.54; p = 0.002). The minimum oxygen saturation (SpO2) in both tests showed a good agreement (intraclass correlation coefficient (ICC) 0.81) and correlated strongly (r = 0.84; p < 0.001). Regarding oxygen desaturation, the total agreement between the tests was 73.3% with a fair Cohen’s kappa (κ = 0.38; p = 0.018), and 93.33% of observations were within the limits of agreement for both tests in the Bland–Altman analysis. Conclusion: The 1STST seems to be a capable tool of detecting exercise-induced oxygen desaturation in COPD. Because it is a less time- and resources-consuming test, it may be applied during the outpatient clinic consultation to regularly evaluate the exercise capacity and exertional desaturation in COPD.

Minute Walk

Background: Six minute walk test (6MWT) is a sub-maximal exercise test, used as a clinical indicator of the functional capacity, in patients with cardiopulmonary diseases. It is simple, objective and reproducible test. The present study was designed to assess correlation of six minute walk test with spirometry parameters, in patients with chronic obstructive pulmonary disease.Methods: In this cross sectional study, fifty patients diagnosed with chronic obstructive pulmonary disease (GOLD criteria) coming to tertiary center were recruited according to inclusion and exclusion criteria. All patients underwent spirometric measurement. Spirometric indices including FEV1, FVC, FEV1/FVC and MVV were tested using computerized spirometer. 6MWT was performed following American Thoracic Society (ATS) guidelines. Percent (%) predicted 6MWD was calculated. Correlation between spirometry and 6MWT was assessed.Results: It was found that correlation between 6MWT and spirometry is statistically significant. There is significant strong positive correlation between percent predicted 6MWD and FEV1 (r=0.850 and p= <0.001), whereas there is significant moderate correlation between percent predicted 6MWD and FVC (r=0.554 and p= <0.001), FEV1/FVC (r=0.509 and p= <0.001) and MVV (r=0.615 and p= <0.001).Conclusions: In chronic obstructive pulmonary disease, percent predicted 6mwd significantly correlated with the spirometry parameters (FEV1, FVC, FEV1/FVC, and MVV). 6MWD decreases as there is decline in the pulmonary function. 6MWT can be a useful replacement of spirometry in assessment of severity of COPD.

Control Tool

Guidelines of treatment of chronic obstructive pulmonary disease (COPD) identify symptom reduction and prevention of exacerbations as the main goals of therapy. Initial pharmacological treatment must be guided by these parameters, and effectiveness must be assessed at each clinical visit. However, there is no clear guidance as to how this assessment must be performed. The concept of control has been well developed in asthma, but it has been elusive in COPD. Patients with COPD may not be completely free from symptoms or exacerbations even under optimized therapy; therefore, control in COPD does not mean cure or absence of symptoms, but rather reaching the best clinical status possible according to the level of disease severity. A control tool has been developed based on a cross sectional evaluation of the impact of the disease and a longitudinal evaluation of stability. Low impact is a disease status defined by at least 3 of the following: low levels of dyspnoea, absence of or white sputum, low use of rescue medication and self-declared walking time of more than 30 minutes a day, and stability is the absence of moderate or severe exacerbations in the previous 3 months. Control can also be defined by COPD Assessment Test (CAT) scores ≤ 10 units for patients with FEV1 ≥ 50% and 16 for patients with FEV1 < 50% and stability as a change in CAT ≤ 2 units. Control of COPD is then defined as a status of low impact and stability. The control tool has been validated prospectively in several studies and has demonstrated to be sensitive to clinical changes and to have a good predictive value for poor outcomes. Clinical criteria are more reliable than CAT scores for the evaluation of control. The control tool is a quick and inexpensive method to evaluate clinical status and future risk of exacerbations that can be used at all levels of healthcare.
