Background: The reliability of intrabladder pressure measurements obtained in nonsupine patients is unknown.
Objectives: To investigate the reliability of measurements of intrabladder pressure obtained with 30 degrees head-of-bed elevation.
Methods: With patients supine, 30 degrees head-of-bed elevation, and instillation of 0 and 25 mL physiological saline, intrabladder pressure was measured in 10 patients: twice by one nurse to assess intraobserver reliability and once by a different nurse to assess interobserver reliability.
