Fourth Quarter and Fiscal 2008 Operating Results Discussion

The Company reported a net sales increase of 6% to $6.5 million in the fourth
quarter 2008 and 12% for full year 2008 to $24.5 million, representing the
second consecutive year of growth. Fourth quarter ICG sales growth was driven by
a combination of a 13% increase in BioZ sales, a 255% increase in ICG Module
sales and an 11% increase in ICG sensor revenue.

ICG Module sales were particularly strong in the fourth quarter with purchases
by General Electric Medical Systems (GEMS) of 72 ICG Modules and Mindray of 80
ICG Modules. The Company also received a firm purchase order in January 2009
from Mindray for an additional 150 ICG Modules deliverable in 2009.

ICG sensor revenue in the fourth quarter was a record $1.9 million, due in part
to the clinical sales team's focused customer service efforts through the launch
of the Comprehensive Customer Care (C3) and ICG CERTIFIED programs.


Gross margin as a percentage of sales increased from 68% to 72% in fiscal 2008,
largely due to lower manufacturing overhead costs, 9% average unit sales price
improvement, and lower inventory reserve requirements.

As part of the Company's efforts to accelerate the return to profitability,
tight expense control resulted in a 1% overall reduction in 2008 operating
expenses with the most significant savings occurring in non revenue generating
areas including General and Administrative expenses, down $321,000 and Research
and Development, down $188,000. The Company surpassed one of its major 2008
goals by achieving $276,000 of positive operating cash flow in the fourth
quarter of 2008.

Fourth Quarter 2008 operating loss improved 47% to $442,000, down from an
operating loss of $830,000 in fourth quarter 2007. The operating loss for fiscal
2008 was $2.0 million, a 58% improvement from fiscal 2007 operating loss of $4.8
million. Fiscal 2008 loss before income taxes, depreciation, amortization and
equity compensation was $1.0 million, an improvement of $2.9 million, or 74%



CEO Comments and Outlook

"We were pleased with the continued improvement in our key operating metrics
during the fourth quarter and throughout 2008," stated Michael K. Perry, Chief
Executive Officer of CardioDynamics. "Despite the challenging business climate,
we achieved our eighth consecutive quarter of revenue growth and accomplished
our goal of generating positive operating cash flow, which was $276,000 during
the quarter. Our recently introduced Comprehensive Customer Care (C3) and BioZ
Certification programs helped grow recurring sensor revenue 11% during the
quarter and should contribute appreciably to our growth plans in 2009.
International, New Markets and our Medis team were particularly strong
contributors on the revenue front, collectively growing 73% in 2008."

Perry continued, "We are conservatively planning for high single to low
double-digit revenue growth in 2009 and have, as a major objective, achievement
of positive operating cash flow for the entire year. With over $6 million in
cash, we have the financial resources to continue to execute our business plan
without the need to access the capital markets during these challenging times."

Perry concluded, "Looking out over the next two to three years, we hope to be
able to achieve solid growth and improved operating performance with our unique
technology in a niche market that is less than 6% penetrated and at the very
early stages of market adoption. We believe that we may be well positioned to
capitalize on the proposed Obama-Biden healthcare reform which focuses on
supporting disease management programs as over 75% of total health care dollars
are spent on patients with one or more chronic conditions, including diabetes,
heart disease and high blood pressure. ICG is ideal to support the disease
management programs for heart disease and hypertension."
