Web14 apr. 2024 · Additionally, an exercise-induced increase in airflow velocity facilitates the movement of inhaled PM 2.5 into the deeper region of the respiratory system . Only a few studies have demonstrated the effect of exercise on endothelial function in high PM 2.5 (HPM 2.5) concentrations and reported inconsistent findings [15,16,17,18]. WebPatients in Group P had significantly lower VAS scores compared to the Group S at 2, 4, and 6 hours after the surgery (P =0.004, P=0.005, P=0.008, respectively). The incidences of nausea and vomiting and dizziness were also significantly higher in Group S than those in Group P (P=0.031, P=0.029, respectively).
