Objective:
To determine the effect of deep breathing exercises on lung functions in apparently healthy smokers.
Methods:
The pilot study was conducted at Isra University, Islamabad, Pakistan, from May to December, 2017, and comprised apparently healthy smokers aged 20-30 years with a minimum smoking history of 5 years. The participants were divided into control and experimental groups. The control group was not given any treatment, while the experimental group was trained on deep breathing exercise techniques. Baseline data was compared after two weeks of intervention. SPSS 21 was used for data analysis.
Results:
Of the 30 subjects, there were 15(50%) in each of the two groups. In the experimental group, significant changes were found in vital capacity, inspiratory capacity, tidal volume, expiratory reserve volume, force expiratory volume, and forced vital capacity (p<0.05). Post-intervention, all parameters improved significantly in the experimental group (p<0.05).
Conclusions:
Deep breathing exercise techniques were found to be useful in healthy smokers for improving lung functions and delaying the development of chronic obstructive lung complications.

Factors Affecting Respiration
Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
Other Factors Affecting Respiration Centers
However, the ability to hold one's breath voluntarily is not limitless. When the CO2 concentration in the blood reaches a critical...

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...
