| Popis: | The effects of withdrawal of ventilatory support on cardiopulmonary function, oxygen consumption and carbon dioxide production were assessed in 25 infants and children within seven days (2.9 ±2.5 days; mean±SD) of an open heart operation, during weaning from ventilatory support. The average age of the patients was 3.4 ±3.5 years and weight 12.4 ±8.3 kg. Heart rate, blood pressure, arterial and central venous blood gas values, and oxyhemoglobin saturations were measured during controlled mechanical ventilation and during spontaneous breathing with continuous positive airway pressure. Simultaneously, V ˙ o 2 and V ˙ co 2 were measured using indirect calorimetry. Withdrawal of ventilatory support effected an expected, significant decrease in arterial pH (7.42 ±0.10 to 7.37 ±0.06; p |
