Abstract:
Transportation of patients may present challenges, especially if they need intensive care, require mechanical ventilation, or are hemodynamically unstable. In the reported case study, Picco-based measurements were used to track hemodynamic changes in a patient throughout the duration of a transfer, which included an air ambulance transport. If air medical transport is indicated, several additional physical and chemical considerations require awareness during the trip, planning, and pretransport patient preparation: first, that decreasing atmospheric pressure leads to reduced blood oxygenation, and second, that intracorporeal volume shifts may occur during takeoff and landing. To our knowledge, our findings represent the first measurements with a Picco system during interhospital patient transport that included an air medical flight.

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
