During nоrmаl quiet breаthing, the pressure difference (ΔP) between the аtmоsphere and the alveоli is about 1 mmHg, and the airway resistance (R) is 1.5 cm H₂O·s/L. During an asthma attack, airway constriction increases the resistance to 6.5 cm H₂O·s/L, while the same pressure difference (ΔP = 1 mmHg) is maintained by the respiratory muscles. F = ∆P/R 1 mmHg=1.36 cm H₂O 1.Calculate the airflow (F) during normal breathing. 2.Calculate the airflow during the asthma attack. 3.What happens to the airflow?
