The residual volume can oscillatorily be estimated in an easy way with the help of diving-gas. The oscillatory unit, furnished with a sensor of density, serves as a quick helium-analyser. An overestimation of the residual volume can appear as a result of the high volatility of the used gas, an underestimation can result because of the non-registration of lung parts with entrapped air. Therefore a differentiated interpretation of the curve of wash-in is suggested. Thus a good conformity can be found with the body plethysmographic results also in patients with obstructive airways diseases including persons with disturbances of ventilatory distribution.

An Intrathecal Pump Misadventure in Two Acts: An Unrecognized Partial Pocket Fill Followed by an Unusual Withdrawal Syndrome Two Months Later.
J Palliat Med

Department of Internal Medicine, University of Utah, Salt Lake City, Utah, USA.
We present a case of a patient with an intrathecal pump who experienced an unrecognized partial pocket fill, leading to an atypical opioid withdrawal characterized by akathisia. A 57-year-old female with multiple myeloma presented to an emergency department with new-onset akathisia requiring admission. Eight weeks prior, her intrathecal pump was refilled with morphine, bupivacaine, and ziconotide.

Introduction: As airway liquid is cleared into lung interstitial tissue after birth, the chest wall must expand to accommodate this liquid and the incoming air. We examined the effect of applying external positive and negative pressures to the chest wall on lung aeration in near-term rabbit kittens at risk of developing respiratory distress.
Methods: Rabbit kittens (30 days; term ∼31 days) were randomised into and groups.

Post-cardiopulmonary bypass (CPB) blood processing is an important component of blood management during cardiac surgery. The purpose of this study is to evaluate several methods of processing post-CPB residual blood. Using a multi-institutional national database (SpecialtyCare Operative Procedural rEgistry [SCOPE]), 77,591 cardiac surgical operations performed in adults (>18 years) between January 2017 and September 2022 were reviewed.

Department of Neurological Surgery, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania, USA.
Background And Objectives: Jugular paragangliomas (JPG) pose a surgical challenge because of their vascularity and complex location. Stereotactic radiosurgery (SRS) offers a minimally invasive management for patients with JPG. Our aim was to evaluate outcomes of Gamma Knife radiosurgery (GKRS) for the treatment of JPG over the long term.
