Physiological considerations in seating.
Physiological changes occur with change of posture. Seating imposes significant effect on the cardiovascular, respiratory, abdominal, renal and neurological systems. The presence of severe skeletal deformities can significantly alter the physiological responses of the individual to changes in posture. In the case of severe kyphoscoliosis profound haemodynamic changes may occur. Lung perfusion h...
متن کاملPulmonary oedema: physiological considerations.
In this paper I propose to attempt to evaluate our knowledge of the mechanisms of acute pulmonary oedema in experimental animals, and to enquire how far it can be applied to our understanding of the phenomenon in man. Our knowledge of the mechanisms of lung oedema is extremely meagre; yet in some respects it may be integrated, with advantage to future investigations. The first issue which shoul...
متن کاملAdrenal corticosteroids--physiological considerations.
1 hour 50 minutes highlights one of the major obstacles preventing coronary care reaching those patients who die soon after the onset of their attack and are referred to the coroner. Appreciation of the fact that delay can be due to referral through the general practitioner has led to an attempt to bypass primary medical care in acute myocardial infarction in the Belfast coronary care scheme.2 ...
متن کاملPulse oximetry--physiological considerations.
Fetal well-being depends on the level of oxygenation in vital organs such as the heart and brain. In this review, we discuss the physiological parameters which underlie the use of pulse oximetry to evaluate fetal conditions intrapartum. Whilst the measurement of haemoglobin oxygen saturation (SaO2) depends on partial pressure of oxygen (PO2), the relation is alinear, is relatively insensitive t...
متن کاملPhysiological variations in thyroid hormones: physiological and pathophysiological considerations.
Thyroid hormone production is regulated via pituitary thyrotropin (TSH) modulation of thyroxine (T4) prohormone secretion by the thyroid gland and regulation of active triiodothyronine (T3) production in peripheral tissues via metabolic events influencing activities of the iodothyronine monodeiodinase enzyme systems. Control at both levels is developmentally regulated and modified in serious no...
