First Quarter 2008 Operating Results Discussion

The Company reported a net sales increase of 22% to $5.8 million. Sales growth
was primarily driven by a 364% increase in international sales and a 14%
increase in the average unit sales price of BioZ monitors compared with the
first quarter of 2007. The significant growth in international sales during the
quarter was the result of the fulfillment of two large hospital customer orders
including the Instituto de Salud del Estado de Mexico (ISEM), the hospital
network of the state of Mexico within the country of Mexico, and an undisclosed
(at the customer's request) eastern European multi-hospital purchaser.

ICG device sales of 266 units included 52 ICG Modules, 214 ICG monitors, 62 of
which were BioZ Dx systems, 6 BioZ Monitors, and 146 Medis ICG monitors.

Overall gross margin percentage decreased 5% to 69%, largely due to the non-cash
provision of $231,000 of additional reserve for excess, slow moving or obsolete
inventory. The additional reserve is primarily driven by lower projected sales
of our older model BioZ monitors and the continued success of our BioZ trade-up
program.

A 1% reduction in operating expenses was achieved through an 18% decrease in
general and administrative expense and 29% reduction in research and development
spending during the period, partially offset by increased investment in selling
and marketing personnel and programs. The increased revenue and gross margin
coupled with reduced operating expenses resulted in an operating loss
improvement of 38% to $852,000, from $1.4 million in the same period in 2007.
Overall net loss improved by 10%, to $1.5 million, or ($0.03) per diluted share.



CEO Comments and Outlook

"We are very pleased with 22% growth in the first quarter, our best growth
quarter in four years," stated Michael K. Perry, Chief Executive Officer of
CardioDynamics. "We continued to make good progress in reducing the operating
loss, down 38% to $852,000, which includes $242,000 of non-cash charges for
depreciation, amortization and equity compensation. We are off to a good start
in the second quarter having already shipped the sizeable backlog that resulted
from domestic orders booked late in the first quarter. Additionally, we recently
increased our U.S. field sales and clinical staff by six additional associates
and have hired a dedicated recruiter to assist with our efforts to add talented
field personnel. Our sights remain on achieving at least 15% revenue growth for
2008 and delivering positive operating cash flow in the fourth quarter."

Perry added, "We are energized to partner with RMS in India through our
previously announced Distribution and Technology License Agreements. RMS has an
extensive presence in the developing healthcare market in India, which we
believe will be instrumental in helping drive continued market adoption of our
proprietary BioZ(R) ICG technology. Additionally, we believe RMS to be a solid
technology partner to potentially utilize for low cost development, clinical
research and manufacturing."
