Ventilatory assistance for treatment of cardiac failure and Cheyne-Stokes breathing

Method and apparatus for the treatment of cardiac failure, Cheyne Stokes breathing or central sleep apnea are disclosed. A subject is provided with ventilatory support, for example positive pressure ventilatory support using a blower and mask. Respiratory airflow is determined. From the respiratory airflow are derived a measure of instantaneous ventilation (for example half the absolute value of the respiratory airflow) and a measure of longterm average ventilation (for example the instantaneous ventilation low pass filtered with a 100 second time constant). A target ventilation is taken as 95% of the longterm average ventilation. The instantaneous ventilation is fed as the input signal to a clipped integral controller, with the target ventilation as the reference signal. The output of the controller determines the degree of ventilatory support. Clipping is typically to between half and double the degree of support that would do all the respiratory work. A third measure of ventilation, for example instantaneous ventilation low pass filtered with a time constant of 5 seconds, is calculated. Ventilatory support is in phase with the subject's respiratory airflow to the fuzzy extent that this ventilation is above target, and at a preset rate conversely.

Method for preparing enoxaparin sodium

The invention discloses a method for preparing enoxaparin sodium, comprising the steps of salinizing, drying, esterfying, alcohol precipitating, oxidizing, alcohol precipitating, fine filtering and freeze drying. In the method provided by the invention, a hydrophilic liquid phase reaction, a hydrophobic liquid phase reaction and a solid phase reaction are adopted, so that macromolecule sodium heparin is degraded into micromolecule sodium heparin with a specific structure, and the molecular weights of products and molecular weight distribution ranges are controlled, thus anti-FIIa activity resulting in bleeding risk is greatly reduced, the anti-FXa activity is relatively improved, and the product effectiveness and safety advantages are obvious. The enoxaparin sodium can be used for effectively preventing venous thromboembolism and pulmonary embolism, can be used for thrombosis before and after operations of orthopedic surgery and neurosurgery, and can be used for greatly reducing apoplexy risk, more effectively reducing death, cardiac failure and recurrent angina of patients suffering from unstable coronary artery syndromes, reducing hypertriglyceridemia and effectively eliminating the side effects of haemorrhage, osteoporosis and induced thrombocytopenia after long-term use of common unfractionated heparin sodium and derivates of common unfractionated heparin sodium.
