简要总结
The purpose of this study is to investigate the short-term effects of two different breathing techniques (the active cycle breathing technique (ACBT) and the pursed lip breathing technique (PLB)) with Thera PEP® on the clearance of secretions and the oxygen saturation of individuals who have recently experienced an acute exacerbation of chronic obstructive pulmonary disease (COPD) in individuals who have recently experienced an acute exacerbation of COPD (COPD). Thirty patients will each have an acute COPD exacerbation seen on them, and then they will be randomly allocated to one of two groups (1. ACBT and PLB; 2. Thera PEP). Participants in a study employing a design known as a within-subject randomized crossover will be given the instruction to carry out each procedure on consecutive days as part of the study. In this study, the dependent variables will include blood pressure, heart rate, oxygen saturation (SpO2), respiratory rate, peak expiratory flow rate (PEFR), visual analog scale (VAS), sputum volume, and the breathlessness, cough, and sputum scale. In addition, the independent variables will include sputum volume (BCSC). The patient's desired course of treatment will also be taken into account. These dependent variables will be examined at three distinct moments in time: at the beginning of the study (the baseline), immediately after treatment, and thirty minutes after treatment has been completed.
详细描述
Methods:
There will be a total of thirty COPD patients recruited. Because of the rapid progression of their chronic obstructive pulmonary disease, these patients are going to need to be hospitalized. An acute exacerbation of COPD is suspected when there is an upper respiratory tract infection, a high temperature for no apparent reason, an increase in wheezing and coughing, or a rise in respiratory rate or heart rate above baseline. All of these symptoms are considered to be indications of an acute exacerbation of COPD. Co-morbidities, including but not limited to angina, indication for ventillatory support, neurological deficits, severe hemodynamic instability (including but not limited to cor pulmonale, cardiac arrhythmias, pulmonary embolism, pneumothorax, congestive heart failure, and GOLD stage IV: very severe COPD), and indication for ventilatory support will be used as exclusion criteria.
Interventions:
Individuals who will satisfy the inclusion and exclusion criteria will be given information regarding the two treatments (ACBT+PLB and PEP therapy to be offered by Thera PEP), and then they will be randomly randomized to either group (A or B) (A or B). Group A patients will get ACBT+PLB on day one of treatment, followed by PEP therapy using Thera PEP on day two. Treatment for patients in Group B will begin with PEP on Day 1, followed by ACBT+PLB on Day 2.
Sitting comfortably, patients receiving Thera PEP will be told to place dental cotton swabs between their cheek and gum, and then under their tongue, to absorb saliva and prevent contamination of the collected sputum by the patient's own saliva. The diameter of the opening will be modified to achieve a ventilation rate of 1:4. The patient will be taught to take in a larger than normal breath but not fill the lungs to capacity in order to maintain a tight seal during exhalation. After completing 10 PEP breaths, the patient will have the mouthpiece removed and be instructed to produce 2-3 "huff" coughs. When secretions need to be brought up, a good cough will do the trick. The patient will be instructed to do three sets of ten breaths each during the length of the therapy, which will last roughly thirty minutes in total. On the day of the ACBT, the patient will be instructed to place dental cotton swabs between the cheek and gum, as well as beneath the tongue, in order to absorb saliva and avoid the collected sputum from being tainted by the patient's own saliva. We'll want the patient to settle in for the duration of the procedure. After that, the patient will be given instructions to perform PLB at a normal tidal volume (for about 6 breaths), followed by 3-4 deep inspirations with relaxed exhalation (thoracic expansion exercise), and finally, another period of breathing control, i.e., PLB, followed by FET, i.e., a deep breath in and to do huff cough, followed by a medium breath in and again a huff cough. About thirty minutes will be spent in this procedure.

结局指标
主要结局
peak expiratory flow rate (PEFR)
时间窗: Day 3
A peak flow meter is a portable, hand-held instrument used to measure a person's maximal rate of exhalation (also known as peak expiratory flow or PEF). The test determines how much of an obstruction there is in the airways by measuring the airflow through the bronchi. Most of the time, people will use liters per minute (L/min) to describe their peak expiratory flow. When recording a patient's Peak Expiratory Flow Rate, the highest value from a set of three measurements will be used. This will be taken at baseline and end of intervention.
the breathlessness, cough, and sputum scale (BCSC)
时间窗: Day 3
Patients will be requested to complete the sputum breathlessness cough scale (one of the dependent variables) on day 0 (when no intervention was given), at the end of day 1 (at bedtime), and at the end of day 2 (at bedtime).
blood pressure
时间窗: Day 3
A digital blood pressure monitor will be used. A tight-fitting arm cuff will be wrapped around the participant's upper arm before being inflated with air. Blood pressure that falls within the range of 90/60 mm Hg to 120/80 mm Hg is considered normal. Measurements of blood pressure will be taken before and after the intervention.
sputum volume
时间窗: Day 3
When the muco-ciliary escalator is working properly, the normal lung produces about 20 to 30 milliliters of mucus daily. When an excessive amount of mucus is formed in the airways and must be expectorated, this excess mucus is referred to as sputum. This will be taken at baseline and end of intervention.
heart rate
时间窗: Day 3
Heart rate will be measured with a digital monitor while the person is supine at the beginning of the study and at the end of the intervention.
oxygen saturation (SpO2)
时间窗: Day 3
The oxygen saturation (SpO2) of the blood is a ratio of the amount of oxygen-carrying hemoglobin to the amount of total hemoglobin. Blood saturation levels of oxygen (SpO2) will be determined with the help of a pulse oximeter. The participant's finger will be positioned to receive the pulse oximeter. On the screen, you'll see a %. The usual range for this percentage, which measures how much oxygen hemoglobin can transport, is between 94% and 100%. This will be taken at baseline and end of intervention.
respiratory rate
时间窗: Day 3
The number of times in a minute that a person breathes is called their respiratory rate. An adult taking it easy should be breathing at a pace of 12-20 breaths per minute. It's abnormal to have a resting respiratory rate of less than 12 or more than 25 breaths per minute. This will be taken at baseline and end of intervention.
visual analog scale (VAS)
时间窗: Day 3
A visual analogue scale (VAS) is a line, typically 10 cm long, with word anchors at either end (such as "no pain" on the far left and "the most extreme pain imaginable" on the far right) to indicate a range of perceived discomfort. In order to indicate the level of pain experienced, the patient makes a mark on the line at the location that best represents their perception of that level of discomfort. A higher score indicate worst intensity of pain. This will be taken at baseline and end of intervention.
