BACKGROUND Digital photoplethysmography is used to assess hemodynamic variability and baroreflex sensitivity. Numerous studies have critically evaluated the accuracy of the photoplethysmographic device against peripheral pressure. The aim of our study was to compare finger blood and aortic root pressure. METHODS We prospectively compared simultaneous recordings of systolic pressure at the aortic root and finger level over three consecutive respiratory cycles in 15 patients (56+/-11 years…

Influence of non-invasive measurements of arterial blood pressure in frequency and time-domain estimates of cardiac baroreflex sensitivity
TLDR
Spectral analysis of cardiac BRS showed a better agreement between estimates obtained from the Finapres and aortic ABP, and the influence of β-blockers on BRS estimates was investigated.
Cerebral critical closing pressure estimation from Finapres and arterial blood pressure measurements in the aorta.
TLDR
When using the Finapres to estimate CrCP and RAP values, the classical linear regression method produces similar results to intra-arterial measurements of ABP for time-averaged values, but H(1) should be preferred in applications analysing beat-to-beat changes in these parameters.
Transient drifts between Finapres and continuous intra-aortic measurements of blood pressure
TLDR
Clinical and/or research applications using the Finapres, such as dynamic cerebral autoregulation modelling or sequence analysis for assessment of baroreceptor sensitivity can be corrupted by the presence of nonrandom short-term fluctuations of the difference signal unless results are averaged for multiple segments of data.
Nachlast und Blutdruckamplitude bei dilatativer Kardiomyopathie. Afterload and Blood Pressure Amplitude in Dilated Cardiomyopathy
TLDR
The responses of amplitude and slope of the systolic blood pressure to small changes in the afterload make it possible to assess left ventricular contractility, the latter of which is impaired in dilated cardiomyopathy.
Noninvasive Evaluation of Varying Pulse Pressures in vivo Using Brachial Sphymomanometry, Applanation Tonometry, and Pulse Wave Ultrasound Manometry.
Influence of noninvasive peripheral arterial blood pressure measurements on assessment of dynamic cerebral autoregulation.
TLDR
The Finapres gives higher values for the efficiency of dynamic CA compared with values derived from aortic pressure measurements, as indicated by biases in the ARI index, CBFV step response, gain, and phase.
The Ability of Pulse Pressure Variations Obtained with CNAP™ Device to Predict Fluid Responsiveness in the Operating Room
TLDR
A value of &Dgr;PPCNAP >11% has a sensitivity of at least 62% in predicting preload-dependent responders to VE in mechanically ventilated patients during general anesthesia, which is significantly higher in responders than in nonresponders.
Time constant of the cerebral arterial bed.
TLDR
A novel cerebral hemodynamic index, a time constant of the cerebral arterial bed (τ), the product of arterial compliance (C(a)) and cerebrovascular resistance (CVR), the result of pulsatile arterial blood pressure (ABP) and transcranial Doppler cerebral blood flow velocity is defined.

Continuous noninvasive finger blood pressure during controlled hypotension. A comparison with intraarterial pressure.
TLDR
In most patients, the Finapres is a useful continuous noninvasive blood pressure monitor, even in the presence of a large bias, and periodic calibration of theFinapres by the difference between Finapre and oscillometrically determined mean arterial pressure is recommended.
Non-invasive continuous finger blood pressure measurement during orthostatic stress compared to intra-arterial pressure.
TLDR
For the assessment of the continuous blood pressure responses to orthostatic stress similar information can be obtained with non-invasive Finapres blood pressure recordings as with invasive recordings.
Physiological influences on continuous finger and simultaneous intra-arterial blood pressure.
TLDR
It is concluded that noninvasive finger blood pressure faithfully follows intra-arterial changes but with clinically relevant offsets, and this technique is best suited for assessing pressure changes.
Finapres tracking of systolic pressure and baroreflex sensitivity improved by waveform filtering.
TLDR
Finger pressure distortion follows a general pattern correctable by waveform filtering, and the results indicate improved systolic pressure tracking after wave form filtering.
Effects of peripheral vasoconstriction on the measurement of blood pressure in a finger.
TLDR
Using noninvasive techniques only, the fall in mean pressure and the pulse amplification between brachial and finger arterial pressure were measured in six anaesthetised female subjects during surgery, finding that the difference tends to decrease with increasing constriction.
Effect of regional and systemic changes in vasomotor tone on finger pressure amplification.
TLDR
To distinguish between changes in regional vascular tone and changes in systemic hemodynamics as a cause of pulse wave amplification, finger pressure, intra-arterial brachial artery pressure, heart rate, and left ventricular ejection time were measured during high-dose intravenous and low-dose intra- arterial infusions of phenylephrine and sodium nitroprusside in eight subjects.
Comparison of Finger and Intra‐arterial Blood Pressure Monitoring at Rest and During Laboratory Testing
TLDR
Beat-to-beat blood pressure recording via FINAPRES provides an accurate estimate of means and variability of radial blood pressure in groups of subjects and represents in most cases an acceptable alternative to invasive blood pressure monitoring during laboratory studies.

Influence of sex on arterial hemodynamics and blood pressure. Role of body height.
TLDR
Arsenial function was studied to assess the possibility that systolic pressure differences in women are related to smaller body size, and in premenopausal women the distensibility of brachial and femoral arteries was higher than in age-matched men, whereas aortic Distensibility was not different.
Aortic Input Impedance in Normal Man: Relationship to Pressure Wave Forms
TLDR
The results suggest that the differences in pressure wave forms are due to differences in reflections in the arterial tree and not secondary to Differences in cardiac function.
