Accounting Policies [Abstract]

Use of Estimates

Use of Estimates - The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates that affect the reported amounts. Actual results could differ from these estimates. Estimates involved in the determination of an allowance for doubtful accounts receivable are considered by management as particularly susceptible to material change in the next year. Other significant estimates relate to stock-based compensation, warrants and beneficial conversion features.

Accounts Receivable

Accounts Receivable - Accounts receivable is carried at its estimated collectible value. Since customer credit is generally extended on a short-term basis, accounts receivable does not bear interest and are uncollateralized. We manage credit risk and determine necessary allowances by evaluating customers’ credit worthiness before extending credit and periodically for collectability, based primarily on customers’ past credit history and current financial conditions and general economic conditions, results of prior collection efforts, the relative strength of our relationship therewith and, in the event of a dispute, its legal position and the estimated cost of proposed collection proceedings. Management has not established a policy for when to charge off uncollectible accounts receivable or to use external collection agencies and makes such decisions on a case-by-case basis. The maximum losses that the Company would incur if a customer failed to pay would be limited to the carrying value of the receivable.

Revenue Recognition

Revenue Recognition – Revenue is recognized when billed, which is approximately when the testing service is performed or CPAP machine is shipped.

Property and Equipment

Property and Equipment - Property and equipment (Note 3) is stated at cost less accumulated depreciation. Depreciation and amortization are computed using the straight-line method over the estimated useful lives ranging from 2 to 12 years. Leasehold improvements are amortized over the shorter of the lease term or the asset’s useful life.

Fair Value Measurements

Fair Value Measurements - The carrying amounts of cash, accounts receivable and accounts payable approximate their estimated fair value due to the short-term nature of these instruments. Since our other financial liabilities are not traded in an open market, we generally use a present value technique, which is a level 3 input, as defined in GAAP, to measure the estimated fair value of these financial instruments, except for valuing stock options and warrants (see below). The rate used for discounting expected cash flows is a risk-free rate adjusted for systematic and unsystematic risk.

The carrying amounts and estimated fair values of long-term debt at March 31, 2018 and December 31, 2017 are as follows:

	March 31, 2018				December 31, 2017
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
Promissory notes	$	4,663,795	$	—	$	4,663,795	$	—
Convertible debt		4,048,000		—		3,798,000		—
Related party loans payable		3,929,933		—		3,019,923		—
	$	12,641,728	$	—	$	11,481,718	$	—

During the first quarter of 2018, there have been 8 additional convertible notes totaling $250,000 and $910,010 was reclassified from accounts payable to related party loans payable.

Cost of Revenues

Cost of Revenues - Costs of revenues consist of sleep testing expenses, supplies, service fees, and product shipping.

Income Taxes

Income Taxes - We are subject to the income tax jurisdictions of the U.S. and multiple state tax jurisdictions. However, our provisions for income taxes for 2017 and 2018 include only state income taxes.

Management has evaluated our tax positions taken or to be taken on income tax returns that remain subject to examination (i.e., tax years 2013 and thereafter federally), and has concluded that there have been no uncertain tax positions (as defined in GAAP) taken that require recognition or disclosure in the consolidated financial statements. In the event of any income tax-related interest or penalties are incurred, they would be included in general and administrative expense.

Stock Options and Warrants

Stock Options and Warrants - We grant stock options and warrants to our non-employee directors, note holders and certain consultants allowing them to purchase our common stock pursuant to approved terms. The estimated value of the warrants issued with debt instruments is recorded as a discount on notes payable and amortized as interest expense over the term of the notes using the effective interest method.
