Abstract

Background: Air conditioners (AC) have become indispensable in the contemporary World. However, their effects on respiratory health need to be explored further using dynamic and static lung functions.

Objectives: The objectives were: 1. To evaluate and compare dynamic parameters (FEV1, FVC, FEV1/FVC, PEFR, and FEF25-75) in AC users and non-users of Bengaluru. 2. To evaluate and compare airway resistance and specific airway conductance as additional parameters.

Materials and methods: After applying ATS-ERS criteria for lung disorders, 30 AC users and non-users of Bengaluru, aged 18-40 yrs were assessed using body plethysmography. A significant association of restrictive pattern was seen in AC users (9 AC users out of 60 participants, Chi-square 8.37, P = 0.0038) having an Odd's ratio of 26.95 (CI: 1.4876 to 488.3558, Z = 2.229, P = 0.0258). Airway resistance (Raw) was comparable in both groups further indicating a non-obstructive pathology.

Conclusion: AC users had a significant decrease in flow rates (PEFR and FEF25-75) as well as an association with restrictive lung disorder suggesting the need for proper ventilation and hygiene. It is crucial to develop policies to maintain indoor air quality.

班加罗尔空调使用者和非使用者静态和动态肺功能的比较研究。

背景：空调在当今世界已经成为不可或缺的一部分。然而，它们对呼吸健康的影响需要利用动态和静态肺功能进一步探索。目标：目标是：1。评估和比较班加罗尔AC用户和非用户的动态参数（FEV1、FVC、FEV1/FVC、PEFR和FEF25-75）。2.评估并比较气道阻力和气道比电导作为附加参数。材料和方法：在应用ATS-ERS肺部疾病标准后，使用体积描记术对30名18-40岁的班加罗尔AC使用者和非使用者进行评估。AC使用者（60名参与者中有9名AC使用者，卡方8.37，P=0.0038）的Odd’s比率为26.95（CI：1.4876至488.3558，Z=2.229，P=0.0258）。两组的气道阻力（Raw）具有可比性，进一步表明其为非阻塞性病理。结论：AC使用者的流速（PEFR和FEF25-75）显著降低，并与限制性肺病有关，这表明需要适当的通风和卫生。制定保持室内空气质量的政策至关重要。
