Differences in Leveling and Zeroing Methods on Intra-Arterial Pressure Parameters in Cardiac Catheterization Patients at Cath Lab Room of RSUP Dr. Hasan Sadikin Bandung

Abstract

Objective: This study aimed to compare intra-arterial pressure (IAP) measurements obtained using standard transducers and zero-line transducers during cardiac catheterization procedures.

Method: A quasi-experimental design was applied involving 73 patients who underwent cardiac catheterization at RSUP Dr. Hasan Sadikin Bandung. Measurements of systolic, diastolic, and mean arterial pressure (MAP) were collected using both standard and zero-line transducer techniques. Statistical analysis was performed using Independent Samples T-tests to evaluate differences in pressure readings between the two methods.

Results: The results showed no statistically significant differences in systolic, diastolic, or MAP values between the standard and zero-line transducer groups (p > 0.05). The average difference in measurements was less than 1 mmHg. This minimal variation is likely due to the relatively uniform anatomical characteristics of participants, with a mean chest cavity diameter of 18.33 ± 2.47 cm.

Conclusion: Zero-line transducers demonstrate comparable accuracy to standard transducers in measuring intra-arterial pressure during cardiac catheterization. In addition to reliable performance, zero-line transducers offer advantages in operational simplicity, making them particularly suitable for sterile, fast-paced clinical environments.
