Cough during therapeutic thoracentesis (TT) is considered an adverse effect. The study was aimed to evaluate the relationship between cough during TT and pleural pressure (Ppl) changes (∆P). Instantaneous Ppl was measured after withdrawal of predetermined volumes of pleural fluid.

Introduction: Therapeutic thoracentesis is highly effective in providing symptomatic improvement in patients with large volume pleural effusion (PE). However, some physiological effects of pleural fluid (PF) withdrawal are still not fully elucidated.

Objectives: The study aimed to evaluate alterations in the breathing pattern, pulmonary function, and arterial blood gases (ABG) in relation to both withdrawn PF volume and pleural pressure (Ppl) changes in patients undergoing therapeutic thoracentesis.

Independent lung ventilation (ILV) is a life-saving procedure in unilateral pulmonary pathologies. ILV is underused in clinical practice, mostly due to the technically demanding placement of a double lumen endotracheal tube (ETT). Moreover, the determination of ventilation parameters for each lung in vivo is limited.

Article Synopsis
  • Pleural manometry helps analyze lung mechanics issues linked to pleural effusion, revealing oscillations in pleural pressure termed pleural pressure pulse (PPP).
  • An observational study with 54 adult patients examined how these pressure oscillations relate to the amount of fluid withdrawn and various health parameters, showing that PPP aligns with the heart's diastole phase.
  • The findings suggest that PPP is more pronounced in patients with larger pleural effusions and certain respiratory patterns, hinting its importance in understanding lung compliance and potential atelectasis, though further research is needed to clarify its significance.

Purposes:: Some controversies exist on the effect of therapeutic thoracentesis (TT) on arterial blood oxygen tension. The aim of this study was to evaluate this issue using a previously developed virtual patient.

Methods:: The analysis was based and supported by clinical data collected during 36 TT.

Purpose: Influence of therapeutic thoracentesis on the pleural pressure (Pp) has been discussed in many clinical studies, however reasons of Pp changes are not precisely established. The aim of the study was to use a previously elaborated virtual cardiopulmonary patient (VP) in analysis of impact of physiological factors on Pp during the procedure.

Methods: Simulations were performed on VP with default values of parameters for which VP simulated the respiratory system of the average 50-year-old healthy Polish woman according to spirometric examination.
