A system and method are disclosed for supporting orotracheal tubing in the mouth and trachea of pediatric patient (e. g. , infant) during prolonged intubation. In general, the system comprises an intraoral component and an extraoral component, each of unitary construction. The intraoral components includes a base portion and an alveolar ridge cushioning flap portion. The base portion has a longitudinal extent, a bore formed along the longitudinal extent for passage and support of a first selected portion of the endotracheal tubing, and a palate facing surface made of a soft resilient material for cushioning the palate of the infant during intubation. The extraoral component of the system includes a flexible lip cushioning flap portion and a tubing clasping portion. A centrally disposed hole is formed in the lip cushioning flap portion for releasable receipt of a projection extending from the alveolar ridge cushioning portion. A substantially rigid stem portion extends from the central portion of the lip cushioning flap portion.

The electrical impedance between two selected points on a person's chest will change in response to spontaneous respiration. The rising edge of the impedance signal is detected to indicate the onset of spontaneous inspiration. The supply of gas by the respirator is synchronized with a selected point during the spontaneous inspiration time period. Apnea conditions are detected to trigger a backup system for supplying gas to the patient periodically despite the lack of spontaneous respiration. If so desired, the triggering and turning off of the respirator need not be synchronized to be simultaneous with the onset of inspiration and exhilation; instead, these may be accomplished at selected times after the initiation of inspiration or exhilation. The triggering and turning off of the respirator can also be accomplished in a manner so that the effects of a wandering baseline are minimized. Instead of using the electrical impedance between two points on a person's chest to indicate spontaneous respiration, other signals may also be used which may for example be electromyograms, signals indicating chest muscle contractions, pneumatic device signals indicating the movement of patient's abdomen and ultrasound signals indicating the movement of the patient's diaphragm.

A method for funding and paying for medical expenses that are not otherwise covered by an insurance plan, particularly elective medical procedures. The funding and payment program includes a managing organization that assists a consumer with identifying what medical services are available, which medical providers provide those services, the costs of the desired services and the potential funding sources to pay for those services. The managing organization works through the consumer's employer and directs the consumer to participating financial institutions who can loan funds to pay for the medical services and directs the consumer to participating medical providers who have the desired qualifications. The financial institution issues a pre-approved debit card or other payment mechanism to the consumer so the medical provider can be paid as soon as the services are provided. Under the program, the consumer has control over which services to obtain and which provider provides those services.

A method of using a Doppler-tipped catheter to produce an indication of the blood flow through an artery can be used for determining shunt fractions through the ductus arteriosus of a neonatal patient. Alternately, this information can be used in the optimizing of a ventilation perfusion match for the patient. Also disclosed is a method of producing a continuous real-time display of the blood flow in an artery with the use of a computer program which can continually produce an indication of the blood flow through an artery.
