Abstract: The Fifth Vital Sign – Understanding End-Tidal Carbon Dioxide Monitoring
Traditionally, vital signs have included temperature, pulse, respiration, and blood pressure. Recently, the monitoring of End-Tidal Carbon Dioxide (ETCO2) has emerged as the so-called “fifth vital sign.” Clinically, ETCO2 serves as an invaluable tool, indicating adequate ventilation, assessing metabolic states, and monitoring patients during sedation and anesthesia. Several factors can influence ETCO2 levels, such as changes in metabolic rates, pulmonary blood flow alterations, and variations in ventilation patterns. The interpretation of capnography waveforms provides critical insights into conditions like bronchospasm, esophageal intubation, and hypoventilation due to drug overdose. ETCO2 monitoring offers real-time data, is non-invasive, and provides instantaneous feedback during resuscitation. However, it is not without challenges, including potential equipment malfunction and artifacts. In conclusion, as the role of ETCO2 monitoring continues to grow in clinical settings, it underscores the need for healthcare professionals to enhance their knowledge and skills in this vital area.
