Abstract
We compared practicality and trustworthiness of invasive arterial blood gas, noninvasive ventilator monitoring, transcutaneous monitoring and pulse oxymeter on the 20 patients whom we applied mechanical ventilation in ICU. The study included 100 synchronous measures including arterial blood gas, ventilator monitor measures, transcutaneous monitor measures and patient side monitor measures of patients. No statistically significant correlation is found between ETCO2 and PtcCO2 as well as ETCO2 and blood gas PCO2 measures. A positive and good level of statistically significant correlation is found between PtcCO2 and blood gas PCO2 measures (p<0.01). The PtcCO2 values which were measured with transcutaneous SPO2/PtcCO2 monitor were fully correlated with blood gas CO2 values, PtcCO2 values are found to be superior to ETCO2 values. When technical problems such as probe maintenance, sensor sensitivity and the need for frequent calibration are overcome, it is also considered that transcutaneous CO2 monitoring will be an essential monitoring for ICU.
