RESPONSE to physical exercise in man has been studied extensively. For any given workload, a predictable change in blood pressure, heart rate, and cardiac output has been shown to occur. Rushmerl has pointed out that the response of stroke volume to exercise, however, may be variable both in experimental animals and in man. He has also demonstrated that not only the amount, but also the directi...
RATIONALE Patients with obstructive sleep apnea (OSA) experience respiratory events with greater frequency and severity while in the supine sleeping position. Postural modification devices (PMDs) prevent supine sleep, although there is a paucity of guidance to help clinicians decide when to use PMDs for their patients. In order for PMDs to treat OSA effectively, patients must experience respira...
Background: The methods of baby's position are an important critical factor in ventilation and oxygenation of tissues. Although the prone position as one of the recommended position has beneficial effect on the development of premature infants, little research has been done. Methods: In a clinical trial among mechanically ventilated infants, hospitalized in the neonatal intensive care units (N...
BACKGROUND Postural changes are known to affect normal lung volumes. A reduction in sitting to supine functional residual capacity (FRC) is well-described in non-obese subjects adopting a supine position. However, postural changes in lung volumes in the obese require further exploration. We aimed to longitudinally address the effects of weight loss on postural changes in lung volumes and pulmon...
