An Introduction of the Vaporized Therapy with Tea Herb Drink for Relieving Agitation due to Pulmonary Encephalopathy

What methods would you choose apart from increasing sedatives for agitation in an advanced patient with hypercapnic encephalopathy due to AECOPD? This is a 94-year-old female who suffered from COPD for over 30 years, occurred with an accelerated episode of cough, productive sputum and a dropping down to 86% in SatO₂ due to a cold weather. A diagnosis of pulmonary encephalopathy (PE) was made on the basis of the subsequent agitation and delirium, and the sedatives, such as quatiepine and haloperidol, had to be given for her mental excitation respectively, but she still pulled out indwelling needle herself and refused to any infusion therapy. As an alternative, a vaporized therapy integrated with tea herb drinking had to be applied to relieving her agitation, being designed as the vaporization of the inhaled oxygenation by means of high-flow oxygenation device (HFOD), with an ampoule of ambroxol mixed into the inhaler and simultaneous drinking of TCM tea herb for reducing sputum, helping dissolve the mucoid bolts inside her terminal bronchioles when being infected. We thought that a better efficacy would be achieved for hypercapnic encephalopathy due to AECOPD if we concentrate on a good ventilation of small airway through the vaporized therapy.
