When someone is on a ventilator, there is always a danger of hyper- or hypoventilating the patient, thus respiratory therapists closely monitor exhaled Pco2 and arterial pH. If arterial pH of a patient on a ventilator is elevated (alkalosis), how should the respiratory therapist adjust the ventilator.
