Brief Summary

This randomized controlled trial evaluates the effectiveness of diaphragmatic deep breathing exercises on pain and hemodynamic parameters in patients after peripheral percutaneous transluminal angioplasty (PTA). Participants were randomly assigned to an intervention group, which performed the breathing exercises, or a control group, which received standard post-PTA care. Pain levels and hemodynamic parameters, including heart rate, blood pressure, and oxygen saturation, were measured before and after the intervention. Socio-demographic and clinical characteristics were also collected to explore potential associations with patient responses. The purpose of this study is to determine whether diaphragmatic deep breathing can reduce post-PTA pain and support hemodynamic stability, thereby improving patient comfort and recovery outcomes.

Outcome Measures

Primary Outcomes (1)

  • Pain intensity after diaphragmatic deep breathing exercises

    Pain intensity measured using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst possible pain).

    Before exercise, immediately after exercise, and one hour post-exercise

Secondary Outcomes (4)

  • systolic BP

    Before exercise, immediately after exercise, and one hour post-exercise

  • Diastolic Blood Pressure

    Before exercise, immediately after exercise, and one hour post-exercise

  • Heart Rate

    Before exercise, immediately after exercise, and one hour post-exercise

  • Oxygen Saturation (SpO2)

    Before exercise, immediately after exercise, and one hour post-exercise

Study Arms (2)

Intervention Group - Diaphragmatic Deep Breathing Exercises.

EXPERIMENTAL

Patients perform structured diaphragmatic deep breathing exercises after peripheral PTA. Pain is assessed using the Numeric Rating Scale (NRS), and hemodynamic parameters including heart rate, systolic and diastolic blood pressure, and oxygen saturation (SpO₂) are measured before, immediately after, and one hour post-exercise.

Behavioral: Diaphragmatic Deep Breathing Exercise

Control Group - Standard Post-PTA Care

NO INTERVENTION

Patients receive routine post-PTA care without diaphragmatic breathing exercises. Pain and hemodynamic parameters (HR, SBP, DBP, SpO₂) are measured at the same time points as the intervention group for comparison.

Interventions

Participants will perform guided diaphragmatic deep breathing exercises after peripheral percutaneous transluminal angioplasty (PTA). The technique involves slow deep inhalation through the nose with abdominal expansion followed by controlled exhalation through the mouth under researcher supervision. The intervention aims to reduce pain intensity and stabilize hemodynamic parameters.

Intervention Group - Diaphragmatic Deep Breathing Exercises.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Aged 18 years and older.
  • Patients diagnosed with peripheral arterial disease (PAD) and scheduled for peripheral percutaneous transluminal angioplasty (PTA).
  • Patients able to communicate effectively and understand instructions.
  • Patients who agree to participate and provide written informed consent.

You may not qualify if:

  • Hemodynamically unstable patients
  • Patients with psychiatric disorders or cognitive impairment affecting communication
  • Pregnant patients
  • Patients with severe respiratory diseases that interfere with breathing exercises
  • Patients receiving opioid analgesics (e.g., pethidine) immediately after the procedure that may influence pain perception or hemodynamic parameters
  • Patients with conditions affecting pain perception (e.g., diabetic peripheral neuropathy) or those receiving chronic analgesic therapy that may alter pain assessment.
