From: Patterns of pleural pressure amplitude and respiratory rate changes during therapeutic thoracentesis
Curves representing changes in respiratory rate (RR) during pleural fluid withdrawal. a All patients (dotted line represents medians). b Patients with initial decline followed by increase of RR in the next measurement points. c Patients with small, but steady increase in RR. d Patients with stable RR followed by its increase in 2nd or 3rd point and decrease at the termination of the procedure
