Figure 1.
Figure 1.
Intrathoracic pressures during the respiratory cycle. Red arrow marks end of expiration, green arrow marks start of inspiration. Left: simulated relaxed breathing in a healthy subject. Right: Simulated breathing in a patient with bronchial obstruction with coincidence of the end of active expiration and start of inspiration. Pressure values (P), except PIP (intrapleural pressure), were generated based on the formula P = a × sin(b × t) + c or P = a × cos(b × t) + c. PAP = pulmonary arterial pressure; PAWP = pulmonary arterial wedge pressure; RAP = right atrial pressure.
