Ask an answerable question (PICO)：
People suffering from lung cancer often complain of dyspnea. In the early stage, dyspnea can be relieved by resting after activity. Before the condition takes a turn for the worse, patients still hope to keep their physiological state under control through various methods. However, As the disease progresses and the dyspnea cannot be improved after a short rest, oxygen needs to be given after evaluation by a doctor. The patient's inquiry motivated the author to explore the effectiveness of breathing exercises in relieving dyspnea in patients with lung cancer.
The Method and Analysis of Literature Review：
(1) Literature search databases include: Cochrane, PubMed, Embase,
Clinicalkey, airiti Library
(2) Keywords include: P (Lung cancer), I (Breathing Exercise), C (Standerd care), O (Dyspnea) combined keywords and synonyms search using Bollinger logic to OR union, AND intersection, limit Articles in Systematic Reviews (SR), Randomized Controlled Trials (RCT), and Systematic Reviews within 5 years, the inclusion criteria are those that meet the keywords, and finally included 1 randomized controlled trial literature.
Critical Appraisal：
The literature review uses the 2010 version of CEBM as the review tool. The level of evidence uses the 2011 Oxford Center for Empirical Medicine evidence level. Randomized controlled trial results show that breathing exercises (abdominal breathing training, pursed mouth breathing, induced spirometer exercise, balloon training) are performed 5 times a week for 12 weeks. A total of 30 minutes/day resulted in significant differences in dyspnea (p < 0.001), inspiratory volume (p = 0.003), anxiety (p < 0.001), and depression (p < 0.001).
Results, Conclusions and Recommendations：
This article explores whether breathing exercises can relieve dyspnea in patients with lung cancer. After going through evidence search steps and screening items, we select items that are consistent with the literature review. We will promote and apply such results and training models in clinical practice. In the process of promotion, we may The unit attributes are complex, the stage of lung cancer affects the patient and the mental state is stable, the acceptable training intensity is different, and many restrictions on the recipients may result in a low parent group, which will affect the length of intervention and the maintenance of results. It is mentioned in the literature that the effect will be less obvious in a shorter period of time. When designing breathing exercise content, the target audience must be considered and the design policy must be adjusted. The results of comprehensive research and evaluation can be used to achieve significant effects on dyspnea and build safety. The exercise program allows lung cancer patients to relieve their dyspnea symptoms through exercises, giving lung cancer patients an additional new option.
