Effects of Alternate Nostril Breathing Versus Diaphragmatic Breathing on Oxygen Saturation and Heart-rate Variability in Post Percutaneous Coronary Intervention Patients
Sponsor: Foundation University Islamabad
Summary
This study is a two-arm randomized parallel group trial designed to compare the effects of alternate nostril breathing vs diaphragmatic breathing on oxygen saturation and Heart-rate variability in hemodynamically stable post-PCI patients. Participants will be randomly allocated in a 1:1 ratio to alternate nostril breathing or diaphragmatic breathing and will receive the allocated intervention for 2 consecutive days with three supervised sessions per day in addition to routine post-PCI care. Oxygen saturation will be assessed using a pulse oximeter and heart-rate variability will be assessed using a Polar H10 sensor at baseline and after the intervention. The study will determine whether there is a difference between two breathing interventions in the prescribed outcome measures.

Conditions
Interventions
Alternate Nostril Breathing
Non-pharmacological breathing interventions administered under physiotherapist supervision for 2 consecutive days with three sessions per day in addition to routine post-PCI care.
Diaphragmatic breathing
Participants assigned to this group will perform diaphragmatic breathing under physiotherapist supervision in addition to routine post-PCI care. The participant will lie supine or sit upright with the back supported, with one hand on the upper chest and the other on the abdomen below the rib cage. The participant will inhale slowly through the nose while allowing the abdomen to rise and then exhale slowly through pursed lips while allowing the abdomen to fall. Post-PCI Day 0 : 3 sessions/day approximately 15mins/session,10 repetitions. Post-PCI Day 1 :3 supervised sessions/day approximately 20 minutes/session, 15 repetitions.
