This study was carried out to determine the effect of breathing exercise performed during peripheral intravenous catheter (PIVC) application on pain, anxiety and patient satisfaction.

The study was completed as a randomized controlled experimental study with a total of 130 individuals who met the inclusion criteria. The Descriptive Characteristics Questionnaire, the State-Trait Anxiety Inventory, and the Numerical Rating Scale were used to collect the data of the study. In addition, Algometer (66 Lb/30 Kg) device was used to evaluate the pain pressure threshold in determining the individuals to be included in the research sample. The individuals in the intervention group were given diaphragmatic breathing exercise while applying the catheter, and the individuals in the control group were inserted without any application.
