Effect of Respiratory Exerciser on Pulmonary Functions of COVID-19 Patients
Effect of Respiratory Exerciser on Pulmonary Functions of COVID-19 Patients, A Prospective Observational Study
COVID-19 infection is the cause of the current pandemic, responsible for loss of life and disability at a rate unseen before. Among survivors, the infection may cause lasting damage, such as permanent loss of lung function.
This study aims to investigate if pulmonary rehabilitation done via supportive devices may reduce or prevent lung function injury. Patients will be chosen among COVID-19 patients who require hospitalization. Patients then will be divided into two groups, those who had used said devices, and compare them to those who had not used them for any reason. After a month, two groups will be evaluated by respiratory function tests, which are expected to provide the results required for a proper comparison.
Pulmonary rehabilitation provided by the supportive devices is expected to either lessen or eliminate a loss of pulmonary function over time, compared to the group who did not use them.

Descrição detalhada
SARS-CoV-2 is a novel coronavirus that is responsible for the current pandemic. Its clinical presentation varies from asymptomatic infection to severe respiratory failure requiring intensive care stay. Loss of respiratory function had been observed in survivors of other coronaviruses in earlier studies. The degree of respiratory function loss and if any intervention may reduce or prevent it remains an issue to be clarified.
The study's goal is to investigate the effects of pulmonary rehabilitation via a supporting device on COVID-19 patients during a follow-up period of one month. The primary method of investigation of pulmonary functions is comparing peak expiratory flow (PEF) at the time of diagnosis and after treatment.
The study hypothesizes that patients who had successfully used a respiratory exerciser or a similar aid device will have better PEF results at the end of the first-month evaluation.
The effect of an incentive spirometer and/or a respiratory exerciser on the pulmonary function results is the main element under investigation in this study. The hospital provides these devices, and in cases, patients demand another device, the patients and their relatives are asked to purchase such equipment.
Pulmonary function tests (PFT) are considered a part of routine evaluation for the COVID-19 patients a month after the treatment. Patients are considered suitable for PFT evaluation if the COVID-19 infectious process is deemed treated, and other contraindications for PFT are not present, such as recent surgery or pneumothorax.
Patients admitted to the pulmonary medicine ward for COVID-19 infection are generally those who already have respiratory comorbidity, including chronic obstructive pulmonary disease, asthma, concurrent pneumonia, and respiratory failure. Due to these reasons, PFT is not considered an acceptable evaluation method during the acute phase and is not requested. PEF testing, on the other hand, remains a simple yet effective alternative compared to PFT due to being more portable, the presence of disposable parts, and overall cost. It is the initial choice of evaluation for patients after a clinical response is seen to treatment and testing is deemed safe.
The respiratory exercise is considered a part of COVID-19 care, primarily due to patients' comorbidities, as mentioned above. This approach is limited in terms of healthcare personnel for on-point pulmonary rehabilitation due to both the disease's infectious nature and limited resources. Respiratory exercise devices are accepted as a reasonable alternative that can be quantitively monitored and provided on a daily basis.
This prospective study plans to evaluate the impact of respiratory exercise provided by incentive spirometers and respiratory exercisers. The evaluation will be performed by comparing the initial PEF result after the end of COVID-19 treatment and subsequent ward discharge; to the PEF result of the PFT evaluation at the end of the first month.

Coortes e Intervenções
Grupo / Coorte |
Intervenção / Tratamento |
|---|---|
|
Incentive Spirometer Group
Patients who would use an incentive spirometer, in addition to standard care provided to COVID-19 patients, will be categorized under "Incentive Spirometer Group".
|
A patient is considered acceptable for the "Incentive Spirometer Group" if the patient can use an incentive spirometer and/or a respiratory exerciser at least four times per day.
A pulmonary medicine specialist will confirm the proper usage of the device.
|
|
Standard Care Group
Patients who did not use an incentive spirometer despite being suggested to do so will be categorized under "Standard Care Group".

Change in Peak Expiratory Flow (Absolute Value)
Prazo: The first PEF testing will be performed seven days after initial diagnosis. The second testing will be performed one month after the hospital discharge, among those who are considered suitable for testing.
|
Two PEF results will be compared in the study.
The first PEF testing will be performed by a handheld device and the second measurement will be performed either by an office spirometer or a handheld device.
The priority will be given to the office spirometer for testing preference.

Forced Expiratory Volume (FEV1)
Prazo: Forced Expiratory Volume (FEV1) was evaluated at the follow-up evaluation, which was performed one-month post-baseline.
|
Forced Expiratory Volume (FEV1) result of the pulmonary function testing was to be used as a pulmonary function parameter.
It was performed via standard office spirometry.
It was calculated as an absolute value (in liters) and as a percentage (compared to the normal population data) It was to be used as a validation method to ensure patients did not have a former yet undiagnosed respiratory disease and to validate the presence of abnormal Peak Expiratory Flow (PEF) values.
|
Forced Expiratory Volume (FEV1) was evaluated at the follow-up evaluation, which was performed one-month post-baseline.
|
|
Forced Vital Capacity (FVC)
Prazo: Forced Vital Capacity was evaluated at the follow-up evaluation, which was performed 1 month post- baseline evaluation.
|
Forced Vital Capacity (FVC) result of the pulmonary function testing was to be used as a pulmonary function parameter.
It was performed via standard office spirometry.
It was calculated as an absolute value (in liters) and as a percentage (compared to the normal population data) It was to be used as a validation method to ensure patients did not have a former yet undiagnosed respiratory disease and to validate the presence of abnormal Peak Expiratory Flow (PEF) values.
|
Forced Vital Capacity was evaluated at the follow-up evaluation, which was performed 1 month post- baseline evaluation.
|
|
Mortality
Prazo: Mortality evaluation will include the time period of one month after hospital discharge. The total evaluation duration will also include the hospitalization period (which is considered an average of 7 days)
|
Mortality will be accepted as a secondary outcome measure, in patients who may not survive until the monthly evaluation for any reason.
|
Mortality evaluation will include the time period of one month after hospital discharge. The total evaluation duration will also include the hospitalization period (which is considered an average of 7 days)
|
|
Discharge to Follow-up Duration (Days)
Prazo: The time frame for "Discharge to Follow-up Duration" consisted of up to two months post-baseline evaluation. When a patient had arrived for the first follow-up evaluation, the time difference between baseline evaluation and this re-evaluation was noted.
|
The duration between the baseline evaluation at the time of hospital discharge and the first follow-up is defined as "Discharge to Follow-up Duration".
There happens a time difference between post-one month evaluation and this definition, due to appointment dates; the exact one month time for a patient happening to be within weekend days or due to delays in respiratory testing.
This could be observed by the time range of patients given here, as some (as seen in patients arriving within 13 days) had come to the hospital earlier, while some ( in the other end of the group, such as those arriving at 41st day) had either arrived late or could not be evaluated with respiratory function testing due to appointment or testing issues up to the day mentioned.
|
The time frame for "Discharge to Follow-up Duration" consisted of up to two months post-baseline evaluation. When a patient had arrived for the first follow-up evaluation, the time difference between baseline evaluation and this re-evaluation was noted.
