“…One of the earliest methods of venous waveform capture was via direct transduction using a peripheral intravenous catheter connected to a pressure transducer. 1 , 2 , 6 , 7 Furthermore, a piezoelectric sensor placed on the volar aspect of the wrist, directly over the superficial veins, has also allowed for non-invasive capture of the peripheral venous waveform. 3 , 4 , 16 , 17 The piezoelectric sensor is connected to a control box that amplifies the venous waveform detected from vibrations related to the low amplitude pulsatile flow of venous blood.…”

“… 1 In patients undergoing hemodialysis, a strong correlation between percent change in PIVA values and ultrafiltration volumes was reported (R 2 =0.77, n = 31), with no significant correlations between volume removed and PVP, blood pressure, or heart rate. 2 Comparison of the least-squares slopes of NIVA on hemodialysis patients prior to onset of intradialytic hypotension (IDH) to slopes on patients without IDH showed a 80% sensitivity and 100% specificity in predicting IDH (AUC 0.87, p < 0.05, n = 16). Furthermore, there was a significant decrease in NIVA value before and after dialysis (1.203 vs 0.868, p < 0.05, n = 38).…”

The peripheral venous system serves as a volume reservoir due to its high compliance and can yield information on intravascular volume status. Peripheral venous waveforms can be captured by direct transduction through a peripheral catheter, non-invasive piezoelectric transduction, or gleaned from other waveforms such as the plethysmograph. Older analysis techniques relied upon pressure waveforms such as peripheral venous pressure and central venous pressure as a means of evaluating fluid responsiveness. Newer peripheral venous waveform analysis techniques exist in both the time and frequency domains, and have been applied to various clinical scenarios including hypovolemia (i.e. hemorrhage, dehydration) and volume overload.

“…Continuous beat-to-beat monitoring of intravascular volume status was used to detect early Stage 1 hemorrhage during perioperative autologous blood donation in patients undergoing cardiac surgery, while they did not find any differences in other physiological parameters such as heart rate, SpO2 or mean arterial pressure [1]. It was also used to detect changes in fluid volume status in spontaneously breathing patients during hemodialysis, as well as the respiratory rate and pulse rate [2].…”

Heart rate variability (HRV) at rest is widely accepted as a non-invasive measure of autonomic nervous system regulation of the heart. A novel technology has been developed by VoluMetrix®that captures venous waveforms via sensors on the volar aspect of the wrist, called NIVAband. In this study, we aim to assess its validity to determine pulse rate variability as a surrogate of HRV. Seven volunteers were recorded while breathing both spontaneously and at a fixed slow pace. Subjects wore a NIVAband and the ECG was recorded simultaneously. Pulses in the NIVA signal were detected using an adaptive threshold on the output of a matched filter. From both beat (ECG) and pulse (NIVA) detections, we derived the power associated to main spectral components of their variability in the low frequency (LF) and high frequency (HF) bands. Good reliability (>0.75) was achieved in average. Mean heart rate and LF power derived from NIVAband and ECG showed no significant differences. HF power, however, was significantly higher in the NIVA measures.

The purpose of this technological notes paper is to describe our institution's experience collecting peripheral venous pressure (PVP) waveforms using a standard peripheral intravenous catheter in an awake pediatric patient. PVP waveforms were collected from patients with hypertrophic pyloric stenosis. PVP measurements were obtained prospectively at two time points during the hospitalization: admission to emergency department and after bolus in emergency department. Data was collected from thirty-two patients. Interference in the PVP waveforms data collection was associated with the following: patient or device motion, system set-up error, type of IV catheter, and peripheral intravenous catheter location. PVP waveforms can be collected in an awake pediatric patient and adjuncts to decrease signal interference can be used to optimize data collection.
