Prepayment speeds can be expressed in SMM (single monthly mortality), CPR (conditional prepayment rate, which is the annually compounded SMM), or PSA (percentage of the Public Securities Association prepayment model). For mortgages at least 30 months old, 100% PSA = 6.0% CPR = 0.51% SMM, equivalent to the full prepayment of 6% of a pool's ...
The CPR mask is the preferred method of ventilating a patient when only one rescuer is available. Many feature 18 mm (0.71 in) inlets to support supplemental oxygen , which increases the oxygen being delivered from the approximate 17% available in the expired air of the rescuer to around 40-50%.
Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation, or mouth to mouth in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
An inspiratory impedance threshold device is a valve used in cardiopulmonary resuscitation (CPR) to decrease intrathoracic pressure and improve venous return to the heart. . The valve is a part of a mask or other breathing device such as an endotracheal tube, and may open at high or low pressures (called "cracking pressures") [citation nee
There are multiple factors during cardiopulmonary resuscitation (CPR) and defibrillation that are associated with success of achieving return of spontaneous circulation. One of the factors in CPR is the chest compression fraction, which is a measure of how much time during cardiac arrest are chest compressions performed.
Cardiac arrests are fundamentally treated with CPR which includes chest compressions. These compressions serve two goals. First, the compressions circulate blood to the brain and other tissues which helps reduce their ischemia and attenuates later post-cardiac arrest syndrome. This goal is accomplished during the compression phase of the CPR ...
The AutoPulse uses a distributing band to deliver the chest compressions. In literature it is also known as LDB-CPR (Load Distributing Band-CPR). The AutoPulse measures chest size and resistance before it delivers the unique combination of thoracic and cardiac chest compressions. The compression depth and force varies per patient.
SMM method formulation, finally helps compute these coefficients of the cylindrical harmonic functions within the cylinder and outside it, at the same time satisfying EM boundary conditions. Finally, SMM accuracy can be increased by adding (removing) cylindrical harmonic terms used to model the scattered fields.
