During the insertion of the pulmonary artery catheter,ventricular dysrhythmias may occur as the catheter passes through the right ventricle.Treatment with lidocaine hydrochloride may be necessary to suppress the irritated ventricle and should be readily available.Withdrawing of the catheter is not within the scope of practice of the nurse and may not be necessary.Having the patient cough and deep-breathe will not correct the problem.The maximum volume of air necessary to inflate the balloon is 1.5 mL.Any additional volumes added may increase the risk of complications.
