From: Non-invasive assessment of Pulse Wave Transit Time (PWTT) is a poor predictor for intraoperative fluid responsiveness: a prospective observational trial (best-PWTT study)

Fig. 3

Boxplots of all PWTT measurements after fluid bolus. Raw measurements in [ms] vs. ∆ = respiratory variation in [%]; c = corrected measurements according to Bazett’s formula vs. non-c = uncorrected measurements; Q vs. R = start of PWTT-measurements with Q- or R-wave in ECG; finger vs. ear = pulse oximetry probe location. Mean, median, Q1 = 1st, Q2 = 3rd quartile of PWTT-measurements
