Showing papers on "Hypoventilation published in 1971"
TL;DR: Hypercapnia, when associated with alkalosis in patients without chronic pulmonary disease, should be recognized as compensatory; rapid reduction in PaCO 2 by mechanical ventilation should be avoided.

TL;DR: The mechanisms for the reduction in PaO2 are complex, including hypoventilation, increased workload of breathing, and most commonly, ventilation perfusion abnormalities, which have important clinical implications which must be evaluated.

TL;DR: J B, girl aged 13 months Born at 31 weeks gestation, birth weight 1-7 kg, had the first of a series of apnoeic spells which continued for the next 25 days which made an uneventful recovery.
Abstract: J B, girl aged 13 months Born at 31 weeks gestation, birth weight 1-7 kg. Her immediate postnatal course was uneventful apart from mild jaundice. At 51 days she had the first of a series of apnoeic spells which continued for the next 25 days. Between attacks her breathing was shallow. Repeated chest X-rays taken during course of illness were normal and all investigations carried out to elucidate the cause of the attacks were negative. The only abnormal findings were a low pH and a compensated respiratory acidosis (Fig 1). The initial Po2 was 52 mmHg. At 80 days these findings began to improve and thereafter she made an uneventful recovery.

TL;DR: The technic for cannulation of the profunda femoris artery and internal mammary artery for obtaining serial arterial blood samples is described.
Abstract: To properly manage the infant after palliative or corrective surgery for congenital cardiac defects, the arterial blood gases must be monitored closely to permit correction of acidosis, hypoventilation, and atelectasis. The technic for cannulation of the profunda femoris artery and internal mammary artery for obtaining serial arterial blood samples is described.

TL;DR: By closely monitoring the patients with blood gas determinations and serial cardiopulmonary physiologic testing, and with the use of tracheal intubation and mechanical ventilatory support where indicated, none of the 17 patients died of hypoxemia, although 3 died of other causes.
Abstract: In major chest trauma, hypoxemia is more prevalent and its causation more complex than has generally been appreciated. The 17 patients with chest trauma and hypoxemia presented here had normal or greater than normal ventilation, and thus hypoventilation could be excluded as a cause of hypoxemia. In virtually all of these patients, ventilation-perfusion imbalance and considerable intrapulmonary shunting of blood were found These abnormalities would not have been apparent from a study of the arterial blood gases alone. By closely monitoring the patients with blood gas determinations and serial cardiopulmonary physiologic testing, and with the use of tracheal intubation and mechanical ventilatory support where indicated, none of the 17 patients died of hypoxemia, although 3 died of other causes.
