PRESS RELEASE DATED APRIL 22, 2003

RESMED ANNOUNCES RECORD FINANCIAL RESULTS FOR
QUARTER AND NINE MONTHS ENDED MARCH 31, 2003

SAN DIEGO, California, April 22, 2003 ResMed Inc. (NYSE: RMD) announced record
revenue and income results for the quarter and nine months ended March 31, 2003.

Revenue for the quarter was $69.0 million, an increase of 31% over the quarter
ended March 31, 2002. Income from operations and net income for the March 31,
2003, quarter increased to $17.1 million and $12.3 million respectively, an
increase of 26% and 33%, on adjusted fiscal 2002 comparables (see reconciliation
table at end of press release). On a GAAP basis, the net income result of $12.3
million represents $0.35 per share (on a fully diluted basis), up from $0.31 per
share in the March 2002 quarter.

Selling, general and administration (SG&A) costs for the quarter were $21.0
million, an increase of $4.6 million over the same period in fiscal 2002. The
increase in SG&A related primarily to an increase in selling and administration
personnel to meet expanding opportunities in the sleep-disordered breathing
market, the inclusion of Servo Magnetics Inc. (SMI) after its May 2002
acquisition, and litigation costs associated with outstanding patent
infringement lawsuits against competitors. SG&A expenditure as a percentage of
revenue was 30% in the March quarter compared to 31% for the same period in
fiscal 2002 and 32% in the quarter ended December 2002.

Research and development expenditure, at 7.3% of revenues, increased during the
three months ended March 31, 2003, to $5.1 million from $3.8 million in the
quarter ended March 31, 2002. The increase of 34% in research and development
outlays reflects ResMed's continuing commitment to innovation within its product
portfolio, as well as an ongoing commitment to clinical research and product
development, particularly in the evolving hypertension, stroke and congestive
heart failure markets. The increase was also affected by a stronger Australian
dollar.

For the nine months ended March 31, 2003, revenues were $192.9 million, an
increase of 30% over the $147.8 million for the nine months ended March 31,
2002. Net income for the nine months was $32.2 million or $0.94 per share,
compared with net income of $27.7 million or $0.81 per share for the same period
in fiscal 2002. Net income increased by 16% over the prior year period, or by
20% against adjusted fiscal 2002 comparables.

Inventories of $49.3 million were higher this quarter compared to the December
2002 quarter, predominantly reflecting a foreign currency translation impact
from a weaker US dollar. Inventory turnover improved 8 days from the December
quarter. Accounts receivable days sales outstanding, at 68 days, were consistent
with the December 2002 quarter and continue to compare favorably to industry
peers.

Peter C. Farrell PhD, Chairman and Chief Executive Officer, commented, "These
record profit and revenue results for the March quarter reflect ResMed's
continuing strong sales and profit growth. Our operating cash flow for the March
quarter was a record-breaking $17.0 million. Domestic sales increased by 27%
over the March 2002 quarter to a record $33.8 million, reflecting very healthy
domestic demand for our sleep-disordered breathing products as well as
contributions from our recently acquired subsidiary, SMI. This growth occurred
despite the full discontinuation of our direct U.S. distribution of MedCare
diagnostic products in the quarter. International sales increased by a healthy
35%, over the March 2002 quarter, reflecting growth across all European markets
as well as a stronger Euro."

Dr. Farrell also commented, "We continue to move forward in the overlapping
areas of sleep-disordered breathing and cardiovascular disease. Together with
Guidant Corporation, we co-sponsored a satellite symposium on sleep-disordered
breathing and heart disease at the American College of Cardiology's 52nd Annual
Scientific Session. We also announced our strategic alliance with MedCath
Corporation, a national provider of cardiovascular services. We are working with
MedCath and its cardiologist partners to help them screen, diagnose, and treat
their patients' sleep-disordered breathing."

Dr. Farrell concluded, "Finally, we were pleased to receive ongoing recognition
from the investment community during the quarter. Investor's Business Daily
ranked ResMed among `The Stable Seventy' public companies that it singled out in
its March 27, 2003 edition as providing `stellar, steady earnings growth over an
extended period.' Similarly, on April 7, 2003, Forbes.com included ResMed as one
of `The 25 Fastest-Growing Tech Companies.' We were particularly gratified
because both groups used criteria based on the past five years of performance in
making their evaluations. We manage our business for long-term success, and we
are proud of our record over the eight years we have been public. This result
marks the 32nd consecutive quarter in which we have achieved record revenue and
earnings."

Looking forward, we project the overall market for our products to continue to
grow at an approximate 20% annual rate over the next 12-18 months. We continue
to believe that our annual revenue growth will exceed this market growth rate.

ResMed is a leading developer, manufacturer, and marketer of medical equipment
for the diagnosis, treatment, and management of sleep-disordered breathing,
selling a comprehensive range of products in over 60 countries.
