During the 6 MWT, participants are monitored continuously using a portable pulse oximeter (measuring pulse rate and oxygen saturation), with their exertion level assessed and documented during the test [ 20] using the Borg perceived exertion scale [ 32].
During the 6MWT, participants were directly observed and monitored continuously by the assessor using a portable pulse oximeter (measuring pulse rate and oxygen saturation), with their exertion level assessed and documented during the test [ 19] using the Borg perceived exertion scale [ 33].
Post-race (<30 min) oxygen partial pressure saturation (SpO2) was measured transcutaneously using a portable bedside monitor with an accuracy of ±3% (Philips Medical Systems, SureSigns VM8, Eindhoven, The Netherlands).
Oxyhemoglobin saturation was monitored continuously during the tests using a portable pulse oximeter (Tuffsat, GE Healthcare, Finland).
Oxygen saturation will be monitored continuously during the treadmill test using a portable oximeter (Nonin 8500A).
Arterial pH, partial pressures of carbon dioxide (PaCO2), and oxygen (PaO2), and haemoglobin oxygen saturation (SaO2, data not shown) were measured immediately after blood sampling using a portable precalibrated blood gas analyzer with precalibrated blood gas cassettes (Roche OPTI CCA Analyzer + OPTI cassette B, Kat Medical, Johannesburg, South Africa).
Heart rate and oxygen saturation were measured and registered every 5 minutes from hypnosis to recovery using a portable modified pulse oximeter (G1B Pulse Oximeter, Quirumed®, Moncada, Spain).
Using a portable stage, he toured plays through Italy.
The results were detected using a portable microchip analyzer.
