Patent number: 8870797Abstract: A method for improving the cardiac output of a patient who is suffering from pulseless electrical activity or shock and yet still displays some myocardial wall motion including sensing myocardial activity to determine the presence of residual left ventricular pump function having a contraction or ejection phase and a filling or relaxation phase. In such cases, a compressive force is repeatedly applied to the chest based on the sensed myocardial activity such that the compressive force is applied during at least some of the ejection phases and is ceased during at least some of the relaxation phases to permit residual cardiac filling, thereby enhancing cardiac output and organ perfusion. Also incorporated may be a logic circuit capable of utilizing multiple sensing modalities and optimizing the synchronization pattern between multiple phasic therapeutic modalities and myocardial residual mechanical function.Type: GrantFiled: January 11, 2010Date of Patent: October 28, 2014Inventor: Norman A.

Patent number: 8857428Abstract: The invention is an apparatus that blocks out light and improves breathing. The apparatus includes a sleep mask with an integral nasal dilation system. The nasal dilation system includes a nasal element mounted with on the nose section of the mask, where the nasal element in one version has a channel through which a band can move substantially orthogonal to the wearer's nose. Sidewalls center the band, and inward folded cuffs retain the band. The band encircles the wearer's head between the mask straps. It is threaded through the slideway and can slide therein equalizing side-to-side forces. The band is elastic and when stretched it generates an opposing force. Pressure is exerted on the nose by using the band in a stretched state. The extended band creates pressure on the slideway, which causes the nose section to press against the nostrils causing them to distend, which in turn dilates the nasal passages, and breathing is improved.Type: GrantFiled: December 22, 2010Date of Patent: October 14, 2014Inventor: Michael J. Spano
