OBJECTIVE: To compare pressure support ventilation (PSV) with volume guarantee (VG) to synchronized intermittent mandatory ventilation (SIMV) in infants with respiratory distress syndrome (RDS). STUDY ...

The efficacy and safety of early high-frequency oscillatory ventilation as compared with conventional synchronized intermittent mandatory ventilation for the treatment of infants with very low birth ...

When you breathe, a certain fraction of your air enters the lungs and blood flows through the capillaries. When this ratio is above or below 0.8, you may have ventilation/perfusion (V/Q) mismatch. A V ...

How Does a VQ Scan Work? The VQ scan is a nuclear scan. It measures airflow, called ventilation, and blood flow, called perfusion, in your lungs. The V and Q make up a math equation that helps doctors ...

Nuclear medicine provides imaging modalities that can be used to observe physiological processes in the human body, particularly in the bones, heart, lungs, renal system and brain.

Educating physicians about ventilation-perfusion scanning as an alternative to CT for the diagnosis of pulmonary embolisms led to a 23 percent decrease in patient exposure, according to a study ...
