Maximal incremental cycling was conducted on an electronically braked cycle ergometer (Corival CPET; Lode) automatically controlled by software (SentrySuite; Vyaire Medical). The protocol consisted of a baseline resting period of 5 min (while participants were seated on the ergometer) followed by 1 min of unloaded cycling. The initial work rate was individualized for each participant, with participants beginning at either 40, 60, or 80 W, depending upon their age, and self‐reported exercise training history. Work rate was increased by 20 W every 2 min. Participants maintained a constant self‐selected cadence above 60 revs/min. Exercise ceased at the limit of tolerance or when cycling cadence could not be maintained above 60 revs/min.

The respiratory resistance and reactance were measured before spirometry using impulse oscillometry (IOS) with Sentry Suite (VyAire Medical) and following the European Respiratory Society (ERS) technical standards for respiratory oscillometry.9 The IOS system was calibrated daily, as suggested by the manufacturer. Measurements were performed using a mouthpiece and a bacterial/viral filter during tidal breathing, and subjects were asked to wear a nose clip and exert a slight manual compression on their faces to reduce the influence of cheek compliance and air leak. IOS values were measured in real‐time as a function of flow volume and pressure for approximately 20 s. Respiratory resistance at 5 Hz (R5) and 20 Hz (R20), the difference between R5 and R20 (R5–R20), reactance at 5 Hz (X5), resonant frequency (Fres), and the area under reactance curve between Fres and 5 Hz (AX) were measured. The mean values of at least three adequate trials (with a coefficient of variability for R5 ≤ 15%) were graphically displayed and used for the analysis.9

These are the same criteria used by the clinician interpreters in our institution. The interpretation guidelines in our institution are based on those recommended by ATS/ERS [4 (link)]. The texts for obstruction, restriction and abnormal DLCO were embedded in specific macros in SentrySuite® (Vyaire Medical, Inc., Mettawa, IL). The clinicians simply need to key in the macros to display the text in the report without manual typing.

The CPET was performed on a specialized, electromagnetically braked cycle ergometer (Corival, Lode B.V., Groningen, The Netherlands) using a CPET system (Vyntus CPX powered by SentrySuite, Vyaire Medical, Mettawa IL, USA) with s breath-by-breath gas analyzer by experienced physicians who perform CPET regularly. The CPET system was calibrated following the manufacturer’s recommendations before each test. An integrated Nonin device was used to measure SpO2 with an ear sensor probe. Stress ECG and HR were monitored at rest and throughout the test using a 12-lead exercise ECG (Mortara Wireless Acquisition Module, Mortara Instrument INC, Milwaukee, WI, USA). Cuff BP was measured every 3 min during exercise and post-exercise recovery, using an adult cuff with a shockproof sphygmomanometer (Gamma G5, HEINE Optotechnik GmbH & Co. KG, Gilching, Germany).

Diffusing capacity was measured using a single-breath method (Jaeger Masterscreen-PFT using Sentry Suite software version 3.1, Vyaire Medical, Würzburg, Germany) using the Viljanen reference values [20 (link)] according to recent guidelines [21 (link)]. The variables evaluated were total lung capacity (TLC), functional residual capacity (FRC), residual volume (RV), haemoglobin-corrected diffusing capacity for carbon monoxide (DLCOc), and specific diffusing capacity (DLCOc/VA). The mean of two partial measurements was the result of the measurement.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
