Summary

Shortness of breath (dyspnea) is commonly experienced during the third trimester of pregnancy due to physiological changes affecting the respiratory system. Non-pharmacological breathing interventions are often recommended to improve breathing comfort and functional capacity in pregnant women.

This randomized controlled trial compared the effects of deep breathing exercises and volume-oriented incentive spirometry on dyspnea, functional endurance, and pulmonary function in women during the third trimester of pregnancy. Eligible participants were randomly assigned to one of two intervention groups. One group performed supervised deep breathing exercises, while the other group performed volume-oriented incentive spirometry exercises.

Outcomes were measured before and after the intervention period and included the severity of dyspnea, functional endurance, and pulmonary function parameters. The results of this study aim to provide evidence regarding the effectiveness of simple, safe, and non-invasive breathing interventions for improving respiratory outcomes during late pregnancy.

Conditions

  • Dyspnea During Pregnancy
  • Physiological Changes in Pregnancy
  • Reduced Functional Endurance

Interventions

OTHER

Deep Breathing Exercises

Deep breathing exercises focused on diaphragmatic breathing with slow, deep inhalation followed by controlled exhalation. The exercises were performed according to a standardized protocol under supervision.

DEVICE

Volume-Oriented Incentive Spirometry

Volume-oriented incentive spirometry involved slow, sustained maximal inspiration using an incentive spirometer device to encourage lung expansion and improve respiratory function, performed under supervision according to protocol.
