Summary: This article reviews various contemporary CO measurement technologies available and their utility in critically ill patients. Pulmonary artery catheter is the most accurate method, but its invasiveness may cause complications. Noninvasive devices predict CO via mathematical modeling, but are prone to errors in clinical situations. CCE provides CO and helps in differential diagnosis.

Summary: Hemodynamic monitoring in children is challenging due to technical limitations and lack of validation against reference methods. Accurate monitoring methods are needed for pediatric patients. The capnodynamic method, which calculates blood flow participating in gas exchange, allows for continuous monitoring of cardiac output and mixed venous oxygen saturation without additional equipment or calibration. This review will discuss the application, limitations, and future potential development of the capnodynamic method in pediatric patients.

Summary: The study aimed to determine the association between the clinician-reported use of ETCO2 or DBP monitoring during pediatric in-hospital cardiac arrest and survival outcomes. A retrospective cohort study was conducted on patients with an invasive airway or arterial line. The results showed that ETCO2 monitoring was associated with 24-hour survival, but not with ROSC.

Summary: Hemorrhage is the leading cause of preventable death from trauma, and accurately monitoring hemorrhage and resuscitation is a challenge. In this study, machine learning algorithms were used to analyze arterial blood pressure waveforms and evaluate the performance of various features in monitoring hemorrhage and resuscitation. The results showed that a single-feature model trained on the half-rise to dicrotic notch (HRDN) feature performed well in detecting decompensation.

Summary: Individualized hemodynamic optimization often requires cardiac output monitoring, which can be achieved through noninvasive technologies. Care providers need to be aware of the advantages and limitations of these technologies to ensure appropriate use for patient care.

Summary: This article reviews the analytical techniques for monitoring atmospheric carbonyl compounds. The methods are categorized into real-time measurements and time-integrated measurements and compared. The advantages and limitations of each technique, as well as the challenges and solutions for measurement bias, are discussed. Recommendations for selecting a suitable technique are provided.

Summary: This study investigated the cardiovascular instability during endotracheal intubation in critically ill patients and analyzed the hemodynamic effects of induction agents and positive pressure ventilation. The results showed that propofol administration decreased total peripheral resistance index while maintaining cardiac index. Etomidate and ketamine increased total peripheral resistance index, with etomidate also leading to a decrease in cardiac index. Positive pressure ventilation had minimal impact on hemodynamics.

Summary: This article discusses the ethical challenges and considerations related to the use of extracorporeal membrane oxygenation (ECMO), emphasizing the importance of autonomy, beneficence, nonmaleficence, and justice as core principles of bioethics. Case studies highlight the careful balance between benefits and harms in ECMO utilization, as well as the nuances of physician autonomy and variations in interpretation and delivery of ECMO among different providers.

Summary: Rapid, non-operator-dependent, non-invasive cardiac output monitoring (COM) is feasible in over 90% of emergency department (ED) patients with hemodynamic instability (HI). Patients with hypotension have lower cardiac index (CI), mean arterial pressure (MAP), and heart rate compared to patients with only tachycardia, while patients with suspected infection have a lower systemic vascular resistance index (SVRI).

Summary: This study assessed whether expedited delivery to a cardiac arrest center compared with current standard of care reduces deaths in patients with resuscitated cardiac arrest. The results showed that expedited delivery to a cardiac arrest center did not reduce mortality in adult patients without ST elevation.

Summary: The study aimed to assess the impact of systemic vascular resistance on the reliability of the ClearSight system for measuring blood pressure and cardiac output. Results showed acceptable accuracy in measuring BP and tracking BP changes, but poor accuracy in CO measurement and its trending ability in different SVR states.

Summary: This study compared clinical hypovolemia with three diagnostic adjuncts and found that none of the adjunct measurements correlated with clinical hypovolemia or with each other, highlighting the challenge of fluid status assessment in critical care. Ultrasound should be used to assess for right ventricular dysfunction prior to resuscitation.

Summary: This study aimed to explore the feasibility and agreement of using a non-invasive cardiac output monitor (NICOM) for measuring hydration status in acute ischemic stroke patients. The results showed that NICOM assessment was feasible and had some agreement with the indirect marker BUN/creatinine ratio.
