FOR IMMEDIATE RELEASE

ZOLL Medical Corporation Announces Second Quarter Results

Chelmsford, MA  Tuesday, April 26, 2005 – Non U.S. Military Sales Grow 22% Year over Year

Chelmsford, MA, April 26, 2005 – ZOLL Medical Corporation (NASDAQ: ZOLL), a manufacturer of resuscitation devices and software solutions, today announced second quarter revenues of $52,491,000, an increase of 3% as compared to revenues of $50,761,000 for the comparable prior year quarter. Net income for the quarter decreased to $159,000 or $0.02 per diluted share as compared to $1,558,000 or $0.17 per diluted share in the second quarter of the prior year.

During the quarter, the Company shipped $2.9 million of product to the U.S. Military, an expected decline from the $10.1 million shipped in the same period last year. Excluding sales to the U.S. Military during both periods, the Company experienced sales growth of 22%.

Sales to the North American market decreased by 1% to $39.8 million as compared to $40.3 million for the comparable prior year period. North American hospital revenues decreased to $17.0 million as compared to $21.1 million in the second quarter of last year. Included in the North American hospital revenue were sales to the U.S. Military. Excluding the U.S. Military, North American sales increased 22% from $30.2 million to $36.9 million, while North American hospital revenues increased 27% from $11.1 million to $14.1 million. Sales to the North American pre-hospital market increased 26% to $17.8 million, as compared to $14.1 million in the comparable prior year period. International revenues increased by 20% to $12.7 million as compared to $10.5 million in the second quarter of last year. AED product sales, including the new AED Pro™ product which began shipping at the end of the quarter, increased by 21% to $8.4 million compared to $7.0 million in the same period last year. The Company shipped approximately $1.6 million of AutoPulse™ product during the quarter.

Richard A. Packer, President and Chief Executive Officer of ZOLL, commented, “This quarter was a small step forward for the Company. We experienced growth in multiple markets and we returned the Company to profitability during the quarter. While we saw good growth outside the military, we were not able to make up for the decline in military sales. Our inability to replace the expected drop-off in U.S. Military sales continues to hurt our comparisons to prior year quarters, the decrease in shipments to the U.S. Military was primarily due to the completion of the “Patient Movement Initiative” contract, which standardized all branches of the military’s patient transport defibrillation equipment to ZOLL.”

Mr. Packer continued, “International had another good quarter. We saw particular strength in the UK, Australia, and Latin America. While we are pleased with our progress, there is still opportunity for improvement in this area. Worldwide AED sales for the second quarter were in line with what we believe the market is growing. We continue to work on adjusting our AED strategy to achieve growth, but at the same time focusing on increased bottom line contribution.”

Mr. Packer further noted, “New unit sales of our AutoPulse product increased significantly from approximately 40 units of new sales orders in Q1 to over 100 in Q2. Our pipeline of potential sales continued to grow strongly during the quarter. However, we continue to see that potential customers’ ability to obtain funding for this piece of capital equipment causes a delay in our ability to ramp this product even faster. It is likely to take more time and resources to really get this new product on track.”

Mr. Packer concluded, “During the second quarter, we implemented tight spending controls and achieved our goal of returning to profitability. However, we have not been successful in growing our revenues sufficiently to fill the hole left by lower military sales. Also, we were unable to make progress with respect to building a reasonable backlog, which now stands at just under $2 million, even having achieved good revenue growth in many areas. Therefore, our near term outlook continues to be conservative. During the second half of 2005, we will continue our efforts to build acceptance of the AutoPulse, leverage the effort of our sales and marketing organizations, and gain traction from new defibrillation products, such as the AED Pro. But we also need to build a backlog to help remove the end of quarter effect from our factory and provide less risk to our results. As a result, with our primary financial focus on 2006, we now expect 2005 shipments to be flat with 2004, with EPS of only 25 to 30 cents for the year. While we have not written 2005 off entirely, it is clear that the challenges we face are greater than anticipated at the start of the year, and it will take us until the start of 2006 to get the pieces in place to once again significantly grow our top and bottom lines. We believe that in 2006 with the military comparisons behind us, acceleration of AutoPulse sales and renewed strength from our selling efforts, we will have a strong year in terms of both revenue growth and profitability.”
