     o    Regained compliance with Nasdaq listing requirements

SECOND QUARTER 2008 OPERATING RESULTS DISCUSSION

The Company reported a net sales increase of 15% to $6.2 million. ICG sales
growth was due to a combination of 8% higher average domestic ICG monitor sales
prices, a 20% increase in domestic ICG System sales and an 11% improvement in
international and new market revenue (primarily due to increased revenue from
pharmaceutical companies). The higher average domestic sales price indicates
continued physician acceptance and a solid value proposition for ICG technology.
The improvement in international and new market revenue is a result of the
Company's increased focus on non-Medicare reimbursement dependant markets.
Recurring sensor revenue grew 14% sequentially from first quarter 2008 to $1.7
million, and was up 1% compared to the same period in 2007.

Gross margin as a percentage  of sales  increased  from 63% to 71% in the second
quarter of 2008, largely due to a higher net average sales price per unit, lower
manufacturing  expenses  and  reduced  inventory  charges  related to  potential
excess, slow-moving or obsolete inventory.  Operating expenses were held flat at
$4.9 million and increased revenue,  along with improved gross margins,  drove a
68% improvement in the operating loss. The reduced operating loss,  coupled with
sound working capital management,  resulted in a 43% reduction in operating cash
usage to $490,000 in the quarter,  down from an $860,000 operating cash use from
continuing operations in the same quarter of 2007.



CEO COMMENTS AND OUTLOOK

Michael K. Perry,  Chief Executive Officer of  CardioDynamics,  stated,  "We are
very pleased with the 18% revenue growth  achieved in the first half of 2008 and
15% during the second quarter.  Sales momentum  continues strong and with steady
improvement  throughout the business, we completed our sixth consecutive quarter
of year over year revenue growth.  We are making very good progress in expanding
gross  margins and  reducing the  operating  loss,  down 68% to $476,000,  which
includes $247,000 of non-cash charges for depreciation,  amortization and equity
compensation.  We see sizable  opportunity  to continue to grow the business and
recently hired 12 new sales and clinical personnel to replace open positions and
further  expand our field sales force.  Our operating plan remains to achieve at
least 15% revenue  growth for 2008 and deliver  positive  operating cash flow in
the fourth quarter."

The Company also  announced the  retirement of Russ Bergen as its Vice President
of Operations.  Perry stated,  "We are grateful for the fine  contribution  that
Russ has made to CardioDynamics as our Vice President of Operations for the past
ten years.  He was  responsible  for  establishing  and  growing  our  excellent
operations team that consistently  delivered high quality products and services,
and  also  oversaw  the   manufacturing  and  launch  of  three  generations  of
proprietary,  impedance  cardiography systems. We wish him the very best in this
new stage of life."
