Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes. Our overall effective tax rate for the three months ended March 31, 2017 and 2016 was 4.5% and 26.3%, respectively, which resulted in a provision for income taxes of approximately $690,000 and $1.6 million, respectively. The decrease in the effective income tax rate for the first quarter of 2017, when compared to the first quarter of 2016, was due primarily to the nontaxable gain on the bargain purchase recorded in connection with the acquisition of the critical care division of Argon.
