NOTE A -- BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X.  Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements.  In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have

are not necessarily indicative of the results that may be expected for the year
ended June 30, 1998.  For further information, refer to the consolidated

                                     ==============       ==============


NOTE C -- CONTINGENCIES

As previously disclosed, the Company is a party to actions filed in a federal
District Court in January 1995 and June 1996 in which a competitor alleges that
the Company's sale in the United States of certain products infringes a total of
four of the competitor's patents. In its response to these actions, the Company
has denied the allegations and has separately sought judgment that the claims
under the patents are invalid or unenforceable and that the Company does not
infringe upon the patents. In June 1997, the Court granted the Company's

 
motion for summary judgement that the Company does not infringe one of the
competitor's patents.  In addition, the January 1995 and June 1996 actions have
been consolidated, and discovery is currently underway.  The Company believes
that none of its products infringe any of the patents in question in the event
that any one or more of such patents should be held to be valid, and it intends
to vigorously defend this position.


NOTE D -- ACQUISITIONS

As previously disclosed, the Company acquired LIFECARE International, Inc. 
(since renamed Respironics Colorado, Inc.) on October 21, 1996 and Stimotron 
Medizinische Gerate GmbH on February 26, 1997. Both transactions were treated as
purchases for financial accounting purposes, and accordingly the Company's 
results of operations include the results of operations of Respironics Colorado,
Inc. and Stimotron since their acquisition dates. The results of operations of 
both entities are therefore included in the Company's results of operations for 
the three months ended September 30, 1997 but are not included in the Company's 
results of operations for the three months ended September 30, 1996.

The following unaudited pro forma summary presents the Company's results of 
operations as if the acquisitions had occurred at the beginning of the period 
indicated and does not purport to be indicative of what would have occurred had 
the acquisitions been made as of that date or of results which may occur in the 
future.

NOTE E -- SUBSEQUENT EVENT                 

On November 11, 1997, the Company announced that it had entered into a
definitive agreement to merge with Healthdyne Technologies, Inc. ("Healthdyne").
Under the terms of the agreement, the Company will issue a number of shares of
its common stock determined by multiplying $24.00 by the number of outstanding
shares of Healthdyne (resulting in a transaction value of approximately
$336,000,000) and dividing by the Company's then current share price within a
collar of $26.03 to $31.03. The transaction is expected to be accounted for as a
pooling of interests and is subject to approval by the shareholders of both
companies, regulatory approval, and customary closing conditions. Healthdyne is
a publicly held company headquartered in Marietta, Georgia and is a leading
designer, manufacturer and marketer of technologically advanced medical devices
for use in the home, hospital, and alternate clinical settings. Its sales for
the twelve months ending September 30, 1997 were $146,000,000. The Company
expects to incur one time charges and related adjustments of between $25,000,000
and $30,000,000 in connection with the transaction, representing transaction
costs and other one time charges. The transaction is expected to close in the
first quarter of calendar year 1998.

 
CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS OF THE PRIVATE
SECURITIES REFORM ACT OF 1995

The statements contained in this Quarterly Report on Form 10-Q, specifically
those contained in Item 2 "Management's Discussion and Analysis of Results of
Operations and Financial Condition", along with statements in other reports
filed with the Securities and Exchange Commission, external documents and oral
presentations which are not historical are "Forward-looking statements" within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21B of the Securities and Exchange Act of 1934, as amended.  These
forward looking statements represent the Company's present expectations or
beliefs concerning future events.  The Company cautions that such statements are
qualified by important factors that could cause actual results to differ
materially from those in the forward-looking statements.  Results actually
achieved may differ materially from expected results included in these
statements. Those factors, which were discussed in detail in the Company's
Annual Report on Form 10-K for the year ended June 30, 1997, include the
following: foreign currency fluctuations, regulations and other factors
affecting operations and sales outside the United States including potential
future effects of the change in sovereignty of Hong Kong, customer consolidation
and concentration, increasing price competition and other competitive factors in
the sale of products, intellectual property and related litigation, FDA and
other government regulation, and third party reimbursement.


Item 2.  Management's Discussion and Analysis of Results of Operations
         and Financial Condition


RESULTS OF OPERATIONS

Net sales for the quarter ended September 30, 1997 were $51,918,000 representing
a 52% increase over the $34,112,000 recorded for the quarter ended September 30,
1996.  Sales for the current quarter included approximately $9,411,000,
generated by Respironics Colorado, Inc. which was acquired by the Company on
October 21, 1996 (prior to its acquisition by the Company, Respironics Colorado,
Inc. was named LIFECARE International, Inc.).  Sales for the current quarter
also include $4,418,000, generated by Stimotron Medizinische Gerate GmbH
("Stimotron") which was acquired on February 26, 1997.   Both acquisitions were
treated as purchases for financial accounting purposes, and accordingly the
Company's results of operations for the quarter ended September 30, 1997 include
the results of operations of Respironics Colorado, Inc. and Stimotron, while
results of operations for the quarter ended September 30, 1996 do not.
Excluding the impact of these acquisitions, sales grew by 18% in the quarter to
quarter comparison. This increase was attributable primarily to increases in
unit and dollar sales for the Company's ventilation, face mask, and obstructive
sleep apnea therapy products.

 
The Company's gross profit was 55% of net sales for the quarter ended September
30, 1997 as compared to 56% for the quarter ended September 30, 1996 .    This
decrease in gross margin percentage was primarily caused by reduced average
selling prices for certain of the Company's products.  These reductions in
average selling price, which had been expected, resulted from increasing
competition in the Company's primary product lines, particularly in OSA,
relative to the Company's large, national customers who received lower prices.
In addition, during the current quarter, manufacturing support costs increased
at a rate slightly higher than the overall rate of sales growth.

General and administrative expenses were $6,518,000 (13% of net sales) for the
quarter ended September 30, 1997 as compared to $4,622,000 (14% of net sales)
for the quarter ended September 30, 1996. The increase in absolute dollars was
due primarily to the addition of  expenses incurred by the Company's new
subsidiaries, Respironics Colorado, Inc. and Stimotron. In addition,
amortization of the goodwill generated by the acquisitions of these companies is
included in general and administrative expenses for the quarter ended September
30, 1997.

Sales, marketing and commission expenses were $9,871,000 (19% of net sales)  for
the quarter ended September 30, 1997 as compared to $5,574,000 (16% of net
sales)  for the quarter ended September 30, 1996.  The increase in these
expenses was due primarily to the addition of  expenses incurred by  Respironics
Colorado, Inc. and Stimotron for the quarter ended September 30, 1997.
Respironics Colorado, Inc. has a network of 19 fully staffed customer
satisfaction centers throughout the United States, a portion of the costs of
which are included in sales, marketing and commissions.  In addition, because
Stimotron serves as the Company's exclusive distributor in Germany, most of its
operating expenses are included in sales, marketing, and commissions.

Research and development expenses were $2,935,000 (6% of net sales) for the
quarter ended September 30, 1997 as compared to $2,492,000 (7% of net sales) for
the quarter ended September 30, 1996.  This increase in absolute dollars
reflects the new product development efforts conducted during the quarter to
support product introductions in the Company's major product groups, including
the next generation of products in the Great Performers family and the BiPAP
Harmony Home Ventilatory Support System.  In some cases, initial distribution
has been, and will be, conducted in international markets until regulatory
clearance to market in the U.S. is obtained.

The Company's effective income tax rate was 40% for the quarter ended September
30, 1997  as compared to 39% for the quarter ended September 30, 1996.  Changes
in the Company's effective income tax rate are due primarily to changes  in the
relative proportion of the Company's taxable income attributable to its United
States and European operations versus taxable income attributable to its Far
East operations because the United States and European operations pay income
taxes at a higher rate (approximately 41%

 
before available income tax credits) than do the Far East operations. For the
quarterly comparison, the proportion of taxable income attributable to the
United States and European operations increased, due in part to taxable income
generated by the Company's new subsidiaries, Respironics Colorado, Inc. and
Stimotron. In addition, the amortization of the goodwill generated by the
acquisitions is not a tax deductible expense, and therefore also contributed to
the increased effective income tax rate.

As a result of the factors described above, the Company's net income was
$5,501,000 (11% of net sales) or $0.27 per share for the quarter ended September
30, 1997 as compared to $4,453,000 (13% of net sales) or $0.22 per share  for
the quarter ended September 30, 1996.


FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

The Company had working capital of $74,048,000 at September 30, 1997 and
$71,038,000 at June 30, 1997.   Net cash provided by operating activities was
$9,842,000 for the quarter ended September 30, 1997 as compared to  $7,176,000
for the quarter ended September 30, 1996.    The increase in net cash provided
by operating activities for the current quarter was due primarily to higher
earnings, a decrease in inventory, and an increase in accrued income taxes.

Net cash used by investing activities was $5,519,000 for the quarter ended
September 30, 1997 as compared to $1,126,000 for the quarter ended September 30,
1996. The majority of the cash used by investing activities for both periods
represented capital expenditures, including the purchase of production
equipment, computer and telecommunications equipment, and office equipment. The
funding for the investment activities in the current and prior quarter was
provided by positive cash flows from operating activities.

In October 1996, the Company announced that its status with Apria Healthcare
("Apria") had changed from "primary supplier" to sole "secondary supplier"
effective in November 1996.  This change adversely affected sales levels for the
three month period ended September 30, 1997.  Subsequent to the Company's
change in status, it has focused on demonstrating to Apria superior effort and
added value service surrounding its product offerings.  In spite of these
efforts, sales to Apria during the current quarter decreased from prior year's
levels.  While the Company cannot predict with certainty what actions Apria will
ultimately take relative to future supplier selection (especially in light of
Apria's announced intentions to review restructuring alternatives, including a
possible merger or sale), the Company has been requested to submit a proposal to
Apria for a one year supply agreement covering calendar year 1998.   The Company
plans to submit its proposal with the goal of maximizing its share of Apria's
business, but there can be no assurance as to the outcome of the proposal
process.

 
On November 11, 1997, the Company announced that it had entered into a
definitive agreement to merge with Healthdyne Technologies, Inc. ("Healthdyne").
Under the terms of the agreement, the Company will issue a number of shares of
its common stock determined by multiplying $24.00 by the number of outstanding
shares of Healthdyne (resulting in a transaction value of approximately
$336,000,000) and dividing by the Company's then current share price within a
collar of $26.03 to $31.03. The transaction is expected to be accounted for as a
pooling of interests and is subject to approval by the shareholders of both
companies, regulatory approval, and customary closing conditions. Healthdyne is
a publicly held company headquartered in Marietta, Georgia and is a leading
designer, manufacturer and marketer of technologically advanced medical devices
for use in the home, hospital, and alternate clinical settings. Its sales for
the twelve months ending September 30, 1997 were $146,000,000. The Company
expects to incur one time charges and related adjustments of between $25,000,000
and $30,000,000 in connection with the transaction, representing transaction
costs and other one time charges. The cash portion of these charges is expected
to be approximately $16,000,00. The transaction is expected to close in the
first quarter of calendar year 1998.

The Company believes that positive cash flow from operating activities projected
for the remainder of the fiscal year,  the availability of the full amount of
funds under its commercial bank line of credit, commercial bank financing
committed for the additional consideration that may be due for the Stimotron
acquisition, and its accumulated cash and short-term investments will be
sufficient to meet its current and presently anticipated future needs for the
remainder of fiscal year 1998 for operating activities, investing activities,
and financing activities (primarily consisting of payments on long-term debt ).
The Company has not yet determined whether financing will be required for the 
cash portion of the one time charges described above, but expects to be able to 
obtain such financing if necessary.

 
PART 2  OTHER INFORMATION


Item 1:  Legal Proceedings
- -------  -----------------

On November 13, 1997, the Company announced that a federal judge had granted the
Company's motion for preliminary injunction in its previously disclosed patent
infringement suit filed in the United States District Court for the Western
District of Pennsylvania against AirSep Corporation of Buffalo, New York.   The
decision prevents AirSep from manufacturing, distributing and offering for sale
AirSep's Remedy device or any other device using Respironics' patented bi-level
airway pressure technology, including bi-level devices for the treatment of
obstructive sleep apnea.  AirSep can appeal the judge's decision.
