Transcutaneous Monitor
Introduction :
The TCM5 is a transcutaneous monitor that is commonly used in NICU for measuring oxygenation (tcpO2) and Ventilation (tcpCO2) of patient. It consists of a display monitor and a cable connected to a dedicated senor. An internal review revealed that 9 TCM5 sensors were purchased in the past 4 years for replacement, costing a total of $441,846. Given the high expense, immediate improvement is necessary. Therefore, a CQI project was initiated in May 2025 to extend the longevity of TCM5 sensors.
Objectives :
1.To reduce the number of TCM5 sensor replacements by 25 % per year
2.To decrease departmental expenditures on TCM5 sensor maintenance
3.To prevent service interruptions due to lengthy procurement processes of TCM5 sensors
Methodology :
1. Conduct a root cause analysis (RCA) to investigate the frequent need for TCM5 sensor replacements in the NICU.
2. Implement the Plan-Do-Check-Act (PDCA) methodology across two improvement cycles:
First Cycle:
(Plan) Identify and summarize common causes of TCM5 sensor damage
(Do) Educate nurses on preventive measures for proper sensor handling
(Check) Arrange ward patrols to monitor nurses’ compliance of proper handling of TCM5 sensor in incubator
Second Cycle:
(Act) Introduce silicone tubing as a protective cable covering to extend the longevity of TCM5 sensors
Result & Outcome :
1. The number of TCM5 sensor replacements was reduced by 2 (when compared to 2024) as no TCM5 sensor replacement is noted after this project
2. Total annual reduction in departmental expenditures on TCM5 sensor maintenance is $97,964
