PETPET - Positron emission tomography (PET is a nuclear medicine, functional imaging technique that produces a three-dimensional image of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule.
PACPAC - Pulmonary artery catheter - In medicine pulmonary artery catheterization (PAC) is the insertion of a catheter into a pulmonary artery. Its purpose is diagnostic; it is used to detect heart failure or sepsis, monitor therapy, and evaluate the effects of drugs.
PNFPNF - Primary non-function - PNF means total and irreversible loss of function after transplantation - (i) Islet primary nonfunction (PNF) is defined as the loss of islet function after transplantation for reasons other than graft rejection. (ii) Primary nonfunction (PNF) after liver transplantation is life threatening. Future investigations to improve survival among liver transplant recipients with PNF are essential.
PSGPSG - Polysomnography - PSG is a type of sleep study, is a multi-parametric test used in the study of sleep and as a diagnostic tool in sleep medicine. The test result is called a polysomnogram, also abbreviated PSG.
PPVPPV - Positive predictive value - The positive and negative predictive values (PPV and NPV respectively) are the proportions of positive and negative results in statistics and diagnostic tests that are true positive and true negative results
PECLA | iLA | pECLAPECLA - Pumpless extracorporeal lung assist - (i) Pumpless interventional lung assist (iLA) is used in patients with acute respiratory distress syndrome (ARDS) aimed at improving extracorporeal gas exchange with a membrane integrated in a passive arteriovenous shunt. (ii) pECLA is a promising alternative compared with conventional pump-driven systems for patients with ARDS and brain injury, since the pECLA system has minor restrictions, limitations and side effects.
PICCPICC - Peripherally Inserted Central Venous Catheter - PICC or PIC line) is a form of intravenous access that can be used for a prolonged period of time (e.g. for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition).
