  • Title: [Effects of oxygen inhalation therapy on blood and phonomechanography in patients with heart disease, lung disease and cardiorespiratory insufficiency].
    Author: Della Torre F, Clivati A, Mazzola C, Cassani L.
    Journal: Arch Sci Med (Torino); 1979; 136(1):109-15. PubMed ID: 464787.
    Abstract:
    Arterial PaO2 and some phonomechanographic indices were studied during and after a period of 40-60-100% oxygen breathing in fourteen patients (six with pulmonary insufficiency, four with cardiac disease and four with cardiorespiratory insufficiency). Arterial PaO2 was measured at the beginning, every five minutes during and many times after the ventilation. Myocardial performance was also measured by sistolic time: isovolumetric contraction time, left ventricular expulsive time, preejection pressure, deformation time. The authors discuss the modifications of these indices and the clinical involvement of O2 breathing.
