Persistent pulmonary hypertension of the newborn (PPHN) is a severe pulmonary disorder which occurs one in every 500 live births. About 10–50% of the victims will die of the problem and 7–20% of the survivors develop long term impairments such as hearing deficit, chronic lung disease, and intracranial bleed.
Stereo pulse oximeter
InactiveUS6898452B2Exact reproductionAccurate measurementRespiratorsMedical devicesVenous blood specimenVenous blood
An improved pulse oximeter provides for simultaneous, noninvasive oxygen status and photoplethysmograph measurements at both single and multiple sites. In particular, this multiple-site, multiple-parameter pulse oximeter, or “stereo pulse oximeter” simultaneously measures both arterial and venous oxygen saturation at any specific site and generates a corresponding plethysmograph waveform. A corresponding computation of arterial minus venous oxygen saturation is particularly advantageous for oxygen therapy management. An active pulse-inducing mechanism having a scattering-limited drive generates a consistent pulsatile venous signal utilized for the venous blood measurements. The stereo pulse oximeter also measures arterial oxygen saturation and plethysmograph shape parameters across multiple sites. A corresponding calculation of delta arterial saturation and comparison of plethysmograph shape parameters between multiple sites is particularly advantageous for the detection and management of persistent pulmonary hypertension in neonates (PPHN), a patent ductus arteriosis (PDA), and aortic coarctation.

Use of nitrite salts for the treatment of cardiovascular conditions
ActiveUS20100247682A1Increase blood flowEffective vasodilatorOrganic active ingredientsBiocideReperfusion injuryNitrite
It has been surprisingly discovered that administration of nitrite to subjects causes a reduction in blood pressure and an increase in blood flow to tissues. The effect is particularly beneficial, for example, to tissues in regions of low oxygen tension. This discovery provides useful treatments to regulate a subject's blood pressure and blood flow, for example, by the administration of nitrite salts. Provided herein are methods of administering a pharmaceutically-acceptable nitrite salt to a subject, for treating, preventing or ameliorating a condition selected from: (a) ischemia-reperfusion injury (e.g., hepatic or cardiac or brain ischemia-reperfusion injury); (b) pulmonary hypertension (e.g., neonatal pulmonary hypertension); or (c) cerebral artery vasospasm.

Method of reducing pulmonary hypertension and atrial fibrillation after surgery using cardiopulmonary bypass
A method is disclosed for using fructose-1,6-diphosphate (FDP) to reduce and prevent two very serious problems caused by surgery that requires cardiopulmonary bypass. Before bypass begins, a liquid that contains FDP is intravenously injected into the patient, preferably over a period such as about 10 to 30 minutes, to allow the FDP to permeate in significant quantity into the heart and lungs while the heart is still beating. FDP can be added to the cardioplegia solution that is pumped through the heart to stop the heartbeat, and / or during bypass. This treatment was found to reduce two very important and serious problems that have unavoidably plagued CPB surgery in the past, which are: (1) elevated levels of pulmonary vascular resistance (PVR), which includes pulmonary hypertension; and (2) high occurrence rates for atrial fibrillation. Prior to this discovery, there has never been any satisfactory treatment which could reduce the severity and occurrence rates for these two major problems. FDP also can be co-administered in this manner, along with (1) a buffering or alkalizing agent that counteracts acidosis, such as sodium bicarbonate or THAM, and / or (2) a drug that reduces the formation of lactic acid, such as dichloroacetate.
