Blood pressure Drugs' hidden impact on lungs revealed in tiny study

This small pilot study will test two common blood pressure medicines—nicardipine and sodium nitroprusside—in 12 patients with acute respiratory failure and high blood pressure. Researchers will use a special imaging technique called electrical impedance tomography to see how these drugs change the balance of air and blood flow in the lungs. The goal is to find out which drug is safer and better for these critically ill patients.
