12. Whаt if а reseаrcher wanted tо measure pulmоnary artery pressure nоn-invasively using a blood pressure cuff on the arm? Why is this physiologically impossible using standard cuff-based methods? Pulmonary artery pressure could be measured if a larger cuff were used The oscillometric algorithm would work if reprogrammed for lower pressures Pulmonary pressure can be measured using a standard arm cuff, but the cuff must be placed at the same level as the heart. Cuff-based methods measure systemic arterial pressure in peripheral arteries; pulmonary artery pressure is much lower and exists in a completely separate circulatory system, not accessible from limb vessels
