            ICU MEDICAL, INC. REPORTS FIRST QUARTER EARNINGS RESULTS

               o COMPANY RAISES 2006 REVENUE AND EARNINGS TARGETS

SAN CLEMENTE, Calif., April 18, 2006 - ICU Medical, Inc., (Nasdaq: ICUI), a
leading low cost manufacturer of safe medical connectors, custom medical
products and critical care devices, today announced results for the first
quarter ended March 31, 2006.

First quarter revenue was $48.8 million, as compared to $27.1 million in the
same period last year. Net income totaled $6.4 million, or $0.41 per diluted
share, as compared to $4.4 million, or $0.30 per diluted share, in the first
quarter of 2005.

"We are encouraged by our better than expected revenue and earnings results in
the first quarter," said Frank O'Brien, ICU Medical's Chief Financial Officer.
"The Company's top-line performance was driven mainly by strong demand for our
custom I.V. Systems and by our critical care product lines. Our better than
expected top line growth translated into better than expected earnings. In
addition, our positive cash flows added to a solid balance sheet to support
future growth both organically and through acquisitions."

As of March 31, 2006, ICU Medical had $95.9 million in cash and investments and
$132.8 million in working capital. Additionally, the Company generated $8.7
million of cash from operating activities during the first quarter.

Mr. O'Brien concluded, "Based on our top-line outlook for the remainder of 2006,
we are raising our revenue and earnings projections. We now expect to achieve
sales between $188 million and $190 million. In addition we are raising our
diluted earnings per share estimate by $0.10 to a range of $1.56 to $1.59."

ended March 31, 2006 results at 1:30 p.m. PST (4:30 p.m. EST) on Tuesday, April
