The implementation scheme of the CPETS in our PER is summarized in [Figure 1].
The dependent variables compared between the control and CPETS groups included number of PER visits, triage rate, triage accuracy, overall patient wait time, Level 1/2 patient waiting time, and care satisfaction of the patients' families.
The patients visited to PER in control group and CPETS group were similar in terms of gender ratio ( ?
Briefly, the triage rate for the CPETS group (93.40%) was significantly increased compared to that of the control group (90.75%).
Previous maximal CPET studies have found a significant, strong correlation between GET and HRVT using cycle ergometry (11,16,18,19), treadmill running (20), walking (14), and track running (13).
Hence, the main purpose of the present study was to investigate the level of agreement between GET and HRVT during maximal CPET performed within three different exercise modalities (cycling, walking, and running).
Prior to CPET, the subjects were instructed not to engage in any form of physical exercise in the previous 24 h, to abstain from alcohol, soft drinks, and caffeine in the 8 h preceding the test, and fast for 3 h before the test.
The initial and final treadmill speeds for the CPET were fixed at 4.0 and 6.0 km/h, respectively.
CPET was performed on a treadmill ramp protocol (ATL, Ibramed, Brazil) in which the speed and inclination increase were individualized according to the predicted peak oxygen uptake (peak V[O.sub.2]).
Additionally, the following submaximal relationships were determined throughout CPET: [DELTA]HR/[DELTA]V[O.sub.2], [DELTA]VE/ [DELTA]VC[O.sub.2], and [DELTA]VT/[DELTA]lnVE.
Multiple linear regression models were developed considering the spirometric indices and responses to CPET as primary outcomes, and OEPM as the main predictor.
EG presented worse physiological responses to (CPET. There were significant differences for peak V[O.sub.2], VE, VT, BRI, and end-expiratory pressure of [O.sub.2].
