The Changes in Pulse Pressure Variation or Stroke Volume Variation After a “Tidal Volume Challenge” Reliably Predict Fluid Responsiveness During Low Tidal Volume Ventilation*

Critical Care Medicine, 2017
Objectives: Stroke volume variation and pulse pressure variation do not reliably predict fluid responsiveness during low tidal volume ventilation. We hypothesized that with transient increase in tidal volume from 6 to 8 mL/kg predicted body weight, that is, “tidal volume challenge,” the changes in pulse pressure variation and ...

Fixed ventilation during tidal volume breathing bronchial challenge may improve repeatability

Allergy: European Journal of Allergy and Clinical Immunology, 1987
Tidal breathing during bronchial challenge shows both between‐ and within‐subject variation. A challenge protocol permitting controlled ventilation was designed in order to improve repeatability of the method. Twenty‐five patients were challenged twice with an interval of 2 h.

Comparison of the carotid corrected flow time and tidal volume challenge for assessing fluid responsiveness in robot-assisted laparoscopic surgery

Journal of Robotic Surgery, 2023
Abstract Purpose We aimed to evaluate the ability of carotid corrected flow time assessed by ultrasound to predict fluid responsiveness in patients undergoing robot-assisted laparoscopic gynecological surgery in the modified head-down lithotomy position.

Changes in Respiratory Variation of Velocity-Time Integral and Peak Velocity of Left Ventricular Outflow Tract after Tidal Volume Challenge Predict Fluid Responsiveness in Elderly Patients with Low Tidal Volume Ventilation: A Prospective Observational Study

Journal of Cardiothoracic and Vascular Anesthesia
We hypothesized that changes in respiratory variation of velocity-time integral (ΔVTI) and peak velocity (ΔVpeak) of left ventricular outflow tract after tidal volume challenge (TVC) better predict fluid responsiveness in elderly patients with low tidal volume ventilation.A prospective observational study.A tertiary teaching hospital.Ninety-six ...

Bronchial challenge: ventilation during 'tidal volume breathing' inhalation is not constant.

Bulletin europeen de physiopathologie respiratoire, 1987
Standardization of bronchial challenge (BC) in order to improve repeatability of both non-specific and specific challenges is desirable. In the tidal volume breathing BC (tBC), the patient inhales bronchoconstrictor during the entire inspiratory phase of the tidal volume breathing.

Histamine challenge test assessed by the ratio of diaphragm EMG recorded from surface electrodes to tidal volume

Clinical Problems, 2018
The magnitude of tidal volume (VT) depends on neural respiratory drive overcoming respiratory resistance. We hypothesized that the ratio of EMGdi, an index of neural drive, to VT could detect histamine induced changes in lower airway resistance given the assumption that respiratory resistance (except for the lower airway resistance) is unaffected by ...

Predicting Fluid Responsiveness Using Change in Pulse Pressure Variation and Stroke Volume Variation after Tidal Volume Challenge in Postoperative Patients Receiving Lung Protective Ventilation

Journal of the Medical Association of Thailand, 2020
Background: Lung protective ventilation with low tidal volume (VT) is beneficial in patients with intermediate to high risk of post-operative pulmonary complications. However, during low VT ventilation, pulse pressure variation (PPV) and stroke volume variation (SVV) do not predict fluid responsiveness.
