2.   Staff's Comment: Please revise your statement of cash flows to present the
     changes in inventories separately from the changes in other operating
     assets. Also, please revise to present the changes in accounts payable
     separately from the changes in accrued expenses and other long-term
     liabilities. Please refer to paragraph 29 of SFAS 95.

     Response: Per your comment and in accordance with paragraph 29 of SFAS 95,
     we will present changes in inventories separately from changes in other
     operating assets and will separately present changes in accounts payable
     from changes in accrued expenses and other long-term liabilities in future
     annual and quarterly filings. We include below a revised changes in
     operating assets and liabilities section of the Statements of Cash Flows
     for our years ended December 31, 2006, 2005 and 2004, and for the three
     months ended March 31, 2007 and 2006:

Note 2 - Significant Accounting Policies, page F-6
- --------------------------------------------------

3.   Staff's Comment: You state that medical equipment sales and remarketing are
     recorded at the time of shipment, change of ownership or installation
     completion. Please expand your disclosure to describe the different types
     of customer arrangements you enter into related to medical sales and
     remarketing. For each of these types of arrangements, please clarify at
     which time you record revenue and how you determined this is appropriate
     pursuant to SAB Topic 13:A.3.

     Response: Medical equipment sales and remarketing revenues consist of (1)
     sales of moveable medical equipment and related parts and single-use
     disposable items to customers and (2) sales of equipment that include
     installation services.




July 25, 2007
Page 3

     For the first category, we recognize revenue at the point where we either
     deliver the equipment, parts or single-use disposable items to the customer
     ourselves or at the point of shipment, when risk of loss has passed to the
     customer. In either case, we believe the relevant recognition provisions of
     SAB 104/SAB Topic 13:A.3 are satisfied as we have performed all but
     inconsequential or perfunctory obligations and substantial uncertainties
     regarding customer acceptance do not exist, after taking into account an
     allowance we have recorded for returns of such equipment that is based on
     historical experience.

     For the second category, we recognize all revenue when installation is
     complete and the equipment is operational for the customer. At this point,
     we believe that no substantial uncertainties remain with respect to
     customer acceptance and that we have performed all but inconsequential or
     perfunctory obligations.

     In our future filings, we intend this disclosure to look substantially like
     the following:

          "Medical equipment sales and remarketing revenues consist of (1) sales
          of moveable medical equipment and related parts and single-use
          disposable items to customers and (2) sales of medical equipment that
          include installation services. The Company follows the provisions of
          SAB 104 in recognizing these revenues as they are realized and earned
          once an arrangement exists, delivery has occurred and services
          rendered, the price is fixed and collectibility is reasonably assured.
          Sales of moveable medical equipment as well as related parts and
          single-use disposable items are recognized at the point of delivery,
          if performed by us, or at the point of shipment, when risk of loss has
          passed to the customer. Because of the short-term nature of equipment
          installation projects, sales that include installation services are
          recognized when the earnings cycle has been completed--installation
          has been completed, the equipment becomes operational and the customer
          has accepted it. "


Note 7 - Commitments and Contingencies, page F-15
- -------------------------------------------------

4.   Staff's Comment: Please disclose how you account for (a) step rent
     provisions and escalation clauses and (b) capital improvement funding and
     other lease concessions, which may be present in your leases. Paragraph
     5.n. of SFAS 13, as amended by SFAS 29, discusses how lease payments that
     depend on an existing index or rate, such as the consumer price index or
     the prime interest rate, should also be included in your minimum lease
     payments. If, as we assume, they are taken into account in computing your
     minimum lease payments and the minimum lease payments are recognized on a
     straight-line basis over the minimum lease term, the note should so state.
     If our assumption is incorrect, please tell us how your accounting complies
     with SFAS 13 and FTB 88-1.

     Response: We will expand our disclosure as follows:




July 25, 2007
Page 4

          "The Company leases nearly all of its district, corporate and other
          operating locations under operating leases and recognizes rent expense
          on a straight-line basis over the lease terms. Rent holidays and rent
          escalation clauses, which provide for scheduled rent increases during
          the lease term, are taken into account in computing straight-line rent
          expense included in our Statements of Operations. The difference
          between the rent due under the stated periods of the leases compared
          to that of the straight-line basis is recorded as deferred rent within
          other accrued expenses and other long-term liabilities in the Balance
          Sheets. Landlord funded lease incentives, including tenant improvement
          allowances provided for our benefit, are recorded as leasehold
          improvement assets and as deferred rent in the Balance Sheets and are
          amortized to depreciation expense and as rent expense credits,
          respectively."

     The Company does not have any leases where payments included in minimum
     lease payments are dependent upon an index or rate, such as the Consumer
     Price Index.


Note 8 - Employee Benefit Plans, page F-15
- ------------------------------------------

5.   Staff's Comment: Please disclose the extent of your self-insurance in each
     area that you are self-insured. Please also disclose whether or not you
     have excess loss insurance and, if so, the amounts at which this insurance
     coverage begins in each area.

     Response: We will expand our disclosure to include the following:

          "The Company is self-insured for employee health care up to $130,000
          per member per plan year and aggregate claims up to 125% of expected
          claims per plan year. Also, the Company purchases workers'
          compensation and automobile liability coverage with related
          deductibles. The Company is liable for workers' compensation and
          automobile liability claims up to $250,000 and $100,000 per individual
          claim, respectively. Self-insurance and deductible costs are included
          in other accrued expenses in the Balance Sheets and are accrued based
          upon the aggregate of the liability for reported claims and an
          actuarially determined estimated liability for claims development and
          incurred but not reported."


Note 12 - Stock-Based Compensation, page F-20
- ---------------------------------------------

6.   Staff's Comment: Please expand your disclosure to discuss the methodology
     you used to estimate the fair value of your common shares for each period
     presented, including any significant factors and assumptions used to arrive
     at this estimate. Your disclosure in note (3) on page 63 implies that you
     applied discounts in your determination of fair value of your common
     shares. Please disclose the nature of each of the discounts that you used,
     the percentages of these discounts used, and your basis for using these
     discounts. Refer to paragraph 64(c) of SFAS 123(R).




July 25, 2007
Page 5

     Response: We will expand our disclosure to include the following:

          "For each of the periods presented, options were granted with option
          strike prices based on the estimated fair market values of the
          Company's common stock on the date of the grant, as determined by the
          Company's board of directors. Our board of directors considered
          multiple valuation metrics and methods and determined that the most
          appropriate method for the Company, given its unique attributes, was
          an Enterprise Value to EBITDA approach. In order to determine this
          fair market value, during 2004, we applied the Enterprise Value to
          EBITDA multiple per our sale of equity to new common shareholders as
          part of our late 2003 recapitalization. Beginning in 2005, we began
          using an average market multiple approach using the average Enterprise
          Value to forecasted EBITDA multiple from a comparable group of
          publicly traded health care companies. Given the lack of a truly
          comparable peer company, our comparable group was determined by using
          public market players in a generally capital-intensive settings, with
          attributes of our customer base, suppliers and competitors. We then
          applied a discount to such multiple in arriving at the fair market
          value of our common shares, in order to account for the lack of
          liquidity in our shares as well as minority ownership. This discount
          rate was determined through an analysis of the restrictions on the
          transferability of our stock, our impression of the generally accepted
          range for such discount factors for privately held companies based
          upon broad capital market discussions, our progress toward a capital
          event of some type and the inherent risk that such a capital event
          would not be consummated. After considering these factors, the Company
          determined appropriate aggregate discounts of 25% during 2004, 2005
          and through the first quarter of 2006. Thereafter, the aggregate
          discount was reduced to 7.5% in order to account for the increased
          likelihood of a capital event."


Note 13 - Segment Information, page F-23
- ----------------------------------------

7.   Staff's Comment: Please provide a reconciliation between the total of your
     reportable segments' measure of profit or loss to your consolidated income
     (loss) before taxes. All significant reconciling items should be separately
     identified and described. Refer to paragraphs 32 and 33 of SFAS 131. Please
     also separately discuss with quantification business reasons for changes
     between periods in the reconciling items in MD&A.

     Response: The requested reconciliation consists of two items, selling,
     general and administrative expenses and interest expense, both of which are
     presented separately in the Statements of Operations. Neither selling,
     general and administrative expenses nor interest expense are allocated for
     purposes of making operating decisions or assessing segment performance.
     Quantification of business reasons for material changes between periods in
     these reconciling items are currently disclosed in our MD&A. In our future
     annual and quarterly filings, we will include this reconciliation with our
     segment information similar to the table below:

8.   Staff's Comment: Your disclosures indicate that the assets allocated to
     each segment primarily include goodwill and intangible assets. Please
     disclose why you do not allocate any other operating assets for purposes of
     reporting segment assets.

     Response: The reason we do not allocate any other operating assets other
     than goodwill and intangible assets in reporting assets by segment is that
     the Company's assets are, predominantly, managed as corporate assets.
     Furthermore, we do not report such assets separately to our Chief Operating
     Decision Maker ("CODM"), as defined in FAS 131. Since FAS 131 paragraph 29
     states that only those assets that are included in the measure of the
     segment's assets that is used by the CODM need be reported for that
     segment, we do not believe that such allocated asset reporting is required
     by the Statement.

     We will expand our disclosure, however, to include the following:

          "Segment assets for the three business segments (excluding Corporate
          and Unallocated) primarily include goodwill and intangible assets.
          Consistent with the Company's reporting to its Chief Operating
          Decision Maker, other assets are not allocated to the three business
          segments. Thus, assets included in Corporate and Unallocated contain
          all other Company assets."

9.   Staff's Comment: Please address the above comments in your interim filings
     as well.




July 25, 2007
Page 7

     Response: We have considered whether the annual financial statement
     modifications outlined by us in items 2 through 8 above also give rise to
     modifications in our quarterly filings. We do believe that comments 2 and 7
     give rise to such a quarterly modification. We view the other
     modifications, however, to be annual in nature, given our understanding
     that we are obligated to provide disclosure in our quarterly filings when
     necessary to prevent the interim statements from being misleading. Because
     we believe only comments 2 and 7 give rise to this possibility, we will
     modify our future quarterly filings to reflect such comments.

                                      *****

     Further to the Staff's request on page 4 of the comment letter, the Company
hereby acknowledges that:

     o    The Company is responsible for the adequacy and accuracy of the
          disclosure in its filings;

     o    Staff comments or changes to disclosure in response to Staff comments
          do not foreclose the Commission from taking any action with respect to
          the filing; and

     o    The Company may not assert Staff comments as a defense in any
          proceeding initiated by the Commission or any person under the federal
          securities laws of the United States.

                                      *****

     We hope that the foregoing has been responsive to the Staff's comments.
Please address any questions regarding our responses to these comments to the
undersigned at (952) 893-3254.
