Effects of tidal volume challenge on the reliability of plethysmography variability index in hepatobiliary and pancreatic surgeries: a prospective interventional study. [PDF]

J Clin Monit Comput, 2023
Abstract The plethysmography variability index (PVI) is a safe, non-invasive, and useful parameter for evaluating fluid responsiveness but it does not reliably predict fluid responsiveness during low tidal volume (VT) ventilation. We hypothesized that in a ‘tidal volume challenge’ with a transient increase in tidal volume from 6 to 8 ml/kg, the

Tidal Volume Challenge to Assess Volume Responsiveness with Dynamic Preload Indices During Non-Cardiac Surgery: A Prospective Study. [PDF]

J Clin Med
Background/Objectives: The aim of this study is to assess whether changes in Pulse Pressure Variation (PPV) and Stroke Volume Variation (SVV) following a VtC can predict the response to fluid administration in patients undergoing surgery under general anesthesia with protective mechanical ventilation.

Prediction of Preload Responsiveness by the Change in Carotid Peak Velocity Variation with Tidal Volume Challenge

Apollo Medicine
Background and Aims: Tidal volume (TV) challenge was shown to improve the reliability of pulse pressure variation (PPV) in predicting volume responsiveness. Carotid peak velocity (CPV) has similar potential to predict volume responsiveness.

Comparison of Changes in PPV Using a Tidal Volume Challenge with a Passive Leg Raising Test to Predict Fluid Responsiveness in Patients Ventilated Using Low Tidal Volume.

Indian J Crit Care Med, 2021
Tidal volume challenge pulse pressure variation (TVC-PPV) is considered one of the recent reliable dynamic indices of fluid responsiveness (FR); also, passive leg raising (PLR)-induced changes in cardiac output (CO) detected by echocardiography are considered a reliable reversible self-fluid challenge test; many patients share eligibility for both ...

Testing preload responsiveness by the tidal volume challenge assessed by the photoplethysmographic perfusion index. [PDF]

Crit Care
To detect preload responsiveness in patients ventilated with a tidal volume (Vt) at 6 mL/kg of predicted body weight (PBW), the Vt-challenge consists in increasing Vt from 6 to 8 mL/kg PBW and measuring the increase in pulse pressure variation (PPV). However, this requires an arterial catheter.

Methacholine challenges: comparison of different tidal breathing challenge methods

ERJ Open Research, 2021
Tidal-breathing methacholine challenges are now recommended by guidelines, to avoid the bronchoprotective effects of deep inhalation. This study compared different tidal breathing methacholine challenge methods; assessed the agreement between tidal ...

Protective mechanical ventilation in patients without or with lung injury [PDF]

Sanamed, 2014
The mortality of Acute Respiratory Dis­tress Syndrome (ARDS) is still high from 27 to 45% according to Berlin definition. Even in surgical patients without lung injury, the postoperative pulmonary complications (PPCs) are frequent.
