The present study furthered the concept of simulation-based medical education by applying a personalized active learning component. We tested this novel approach utilizing a noninvasive hemodynamic monitor with the capability to measure and display in real time numerous hemodynamic parameters in the exercising participant. Changes in medical knowledge concerning physiology were examined with a pre-and posttest. Simply by observation of one's own hemodynamic variables, the understanding of complex physiological concepts was significantly enhanced...

Clinicians managing obstetric patients are dependent on valid hemodynamic measurements to guide care. Heart rate and noninvasive blood pressure guide most current care. New hemodynamic monitors are being used to report research findings and are being investigated by clinicians for their value to supplement standard monitoring. These include arterial pulse contour analysis, Doppler velocimetry, and bioimpedance among others. This chapter serves to present these new devices with a critical review of their advantages and limitations, and most importantly the validity of their measurements...

BACKGROUND: An ideal arterial pressure monitoring system for perioperative care is required to be accurate, noninvasive, continuous, and risk free. Although several continuous noninvasive arterial pressures (CNAP) are determined on the finger, a new wrist CNAP monitoring system was developed. This prospective study was designed as a randomized-controlled trial to assess its validity in comparison with invasive arterial pressure (IAP) monitoring. PATIENTS AND METHODS: Sixty patients undergoing elective surgery under general anesthesia were enrolled...

Tetra-amelia syndrome is a congenital disorder associated with near or complete absence of all 4 limbs. Noninvasive hemodynamic monitoring may be difficult or impossible in such patients. We describe the use of a finger cuff blood pressure system for continuous noninvasive blood pressure monitoring in an infant with near-complete tetra-amelia undergoing laparoscopic gastrostomy tube placement. This case suggests the potential use of such a blood pressure monitoring system for other patients with comparable deformities...

INTRODUCTION: It is estimated that 3-10% of infants are growth restricted. Growth disturbances may have long-term issues. Doppler allows insight into the fetal response to intrauterine stress. OBJECTIVE: The aim of this study was to detect fetal compromise in intrauterine growth-restricted (IUGR) fetuses by means of biophysical profile (BPP) vis-à-vis Doppler velocimetry studies of the fetal umbilical artery, and to find out which of the two is a better and earlier predictor of fetal compromise...

The use of a noninvasive hemodynamic monitor to estimate arterial stiffness, by measurement of pulse transit time (PTT), was demonstrated in microgravity. The monitor's utility for space applications was shown by establishing the correlation between ground-based and microgravity-based measurements. The system consists of a scale-based ballistocardiogram (BCG) and a toe-mounted photoplethysmogram (PPG). PTT was measured from the BCG I-wave to the intersecting tangents of the first trough and maximum first derivative of the PPG waveforms of each subject...

We described our experience in using the new noninvasive hemodynamic monitoring (esCCO), which allowed recording most important parameters of heart capacity. Infusion therapy during laparoscopic operations might be based on dynamic of systolic blood volume. This functional approach can be used for evaluation of heart reaction on bolus fluid load, to optimike volemic status in situations associated with dynamical blood circulation changes. We compared intraoperative infused fluid volumes, calculated by traditional approach and by target approach...

PURPOSE: Photoplethysmography permits continuous measurement of heart rate and peripheral oxygen saturation and has been widely used to inform clinical decisions. Recently, a myriad of noninvasive hemodynamic monitoring devices using this same technology have been increasingly available. This narrative review aims to summarize the principles that form the basis for the function of these devices as well as to comment on trials evaluating their accuracy and clinical application. PRINCIPAL FINDINGS: Advanced monitoring devices extend photoplethysmography technology beyond measuring oxygen concentration and heart rate...

Shuangshen Ningxin capsule (SSNX), a modern Chinese formula, has been used to treat cardiovascular diseases in Eastern Asia. Our study focuses on the autophagy regulation of SSNX against coronary artery injuries. Myocardial infarction model was established in Chinese miniswines (CMS) by coronary artery balloon injury. SSNX was administered to the CMS for 8 weeks with 4 mg/kg or 16 mg/kg. Myocardial cells were incubated with 20% SSNX medicated serum for 2 hours. Assays were performed to detect the effects of SSNX on (i) coronary artery diameter by angiography, (ii) hemodynamics by noninvasive hemodynamic monitoring system, (iii) plaque burden and plaque volume by intravenous ultrasound (iv) coronary artery histology by H&E staining, (v) autophagosome by transmission electron microscopy, (vi) lactate dehydrogenase (LDH) leakage, and (vii) Beclin-1 and LC3-I/II expressions by Western blot...

INTRODUCTION: Noninvasive hemodynamic (HD) assessments in the emergency department (ED) might assist in the diagnosis, therapeutic plan development and risk stratification of acutely ill patients. This multinational observational study was designed to initiate noninvasive HD measurements prior to any ED patient therapeutic interventions and broadly evaluate them for potential diagnostic, therapeutic and predictive value. METHODS: We enrolled patients with suspected acute heart failure (AHF), sepsis or stroke...

Perioperative hemodynamic optimization of the high-risk surgical patient is associated with reduced postoperative morbidity and mortality. The hemodynamic parameters to be optimized (using goal-directed algorithms) encompass preload, contractility, afterload, volume responsiveness, and end-organ perfusion. Current hemodynamic monitors facilitate multi-modal monitoring of these macro-hemodynamic targets. This review focuses on the variety of invasive, minimally invasive, and noninvasive hemodynamic monitors available to the clinician...

REVIEW

Invasive pulmonary artery catheter measurements are the standard method for assessment of hemodynamic evaluation at the present time. However, this invasive approach is associated with an increase in patient morbidity and without evidence of a reduction in mortality. Doppler echocardiography is a noninvasive method that provides robust data regarding patients' hemodynamic indices. Several parameters are available for noninvasive hemodynamic evaluation using Doppler echocardiography. Most of these measurements are easily obtained and provide a safe alternative to invasive hemodynamic assessment...

AIMS: To investigate the contribution of dysfunction of maternal hemodynamics to renal impairment in preeclampsia (PE). METHODS: Urinary protein excretion, serum creatinine, blood urea nitrogen, uric acid, and glomerular filtration rate were assessed in 571 pregnant women with PE in addition to and noninvasive hemodynamic monitoring. Patients were classified into two groups: PE with renal impairment (glomerular filtration rate <90 ml/min/1.73 m², n = 161) and PE with normal renal function (n = 410)...

BACKGROUND: The purpose of this study was to assess the feasibility of hemodynamic monitoring by bioreactance during the air evacuation of war casualties. METHODS: From June 2011 to January 2012, the French Air Force used a noninvasive bioreactance monitor during the aeromedical evacuation of patients with severe battle injury. Patients were continuously monitored from takeoff (baseline) until arrival. Cardiac index, quality, and viability of signal and fluctuations in values were assessed during the entire flight...

UNLABELLED: The use of Radio Frequency Impedance Interrogation (RFII) is being investigated for use as a noninvasive hemodynamic monitoring system and in the capacity of a biometric identifier. Biometric identification of subjects by cardiosynchronous waveform generated through RFII technology could allow the identification of subjects in operational and potentially hostile environments. Here, the filtering methods for extracting a unique biometric signature from the RFII signal are examined, including the use of Cepstral analysis for dynamically estimating the filter parameters...
