Other Drugs: Bronchodilators are used to improve hypoxemia and reduce pulmonary vascular resistance. Note that use of vasodilators is limited because it may produce systemic hypotension. Studies have indicated that infusion of adenosine into the pulmonary artery has a vasodilating effect more specific to the pulmonary circulation. Inhalation of nitric oxide has also been shown to vasodilate the pulmonary vasculature with no effect on systemic vascular resistance.


To minimize the risk of infection, use the sterile technique during setup and maintenance of the pulmonary artery catheter. Dressings should be changed according to policy, usually every 72 hours. Ask the patient to evaluate chest pain using a scale from 1 to 10, and provide comfort measures in addition to any ordered medication. Reduce energy demands by assisting the patient to a position of comfort, such as the semi-Fowler or Fowler position. Document pulmonary artery catheter readings and report significant changes to the medical team. Monitor the patient for the development of cardiac dysrhythmias.

Allow the patient to verbalize fears, and assist in the development of a realistic perception as the patient appears ready. Incorporate family members and other support system members as appropriate. Help the patient adjust to the limitations imposed by this disorder. Advise against overexertion, and suggest frequent rest periods between activities. The patient may need diver-sional activities during periods of restricted activity. Be sure the patient understands dietary limitations and medication regimens.
