This study aimed to validate the results of Nursing selected from the link NANDA-I-NOC (Nursing Outcomes Classification--NANDA--International) for diagnosis Ineffective Breathing Pattern and Impaired Spontaneous Ventilation in adult intensive care unit. This is a content validation study conducted in a university hospital in southern Brazil with 15 expert nurses with clinical experience and kno...

Pulmonary gas exchange rates in eight patients after open heart surgery were studied during weaning from the ventilator. We investigated continuous positive pressure ventilation (CPPV), intermittent mandatory ventilation (IMV) and spontaneous breathing with continuous positive airway pressure (CPAP). During each mode of ventilation we measured: CO2 production (VCO2), O2 consumption (VO2), cardi...

The role played by the mechanical tissue stress in supporting lymph formation and propulsion in thoracic tissues was studied in deeply anesthetized rats (n = 13) during spontaneous breathing or mechanical ventilation. After arterial and venous catheterization and insertion of an intratracheal cannula, fluorescent dextrans were injected intrapleurally to serve as lymphatic markers. After 2 h, th...

the risk of life-threatening complications during induction of anesthesia in patients with anterior mediastinal mass is well recognized. maintenance of spontaneous ventilation during anesthesia is an accepted standard goal in all published reports. however, the decision to paralyze the patient, which is really needed in most surgical procedures, is still a challenging event. in this study, “man...

Most patients who require mechanical ventilation for longer than 24 hours, and who improve the condition leading to the indication of ventilatory support, can be weaned after passing a first spontaneous breathing test. The challenge is to improve the weaning of patients who fail that first test. We have methods that can be referred to as traditional, such as the T-tube, pressure support or sync...

Introduction: Hyperpolarized (HP) noble gas MRI and MRS in the lungs on spontaneous breathing mice is expected as a valuable modality for drug discovery or development of the methods for evaluating physiological changes. Since the measurements under the spontaneous breathing condition are fully non-invasive protocol without using mechanical ventilation, this technique allows a long-term and the...

In rabbits which were initially conscious or lightly anaesthetized with pentobarbitone, ketamine respectively increased or did not change arterial pressure, whereas in mechanically ventilated animals there was prolonged depression of both pressure and pregangkioinic sympathetic activity. Although respiratory rate slowed during spontaneous ventilation, blood-gas changes were not responsible for ...

Nocturnal nasal intermittent positive pressure ventilation (NIPPV) is an effective means of normalizing awake blood gases in patients with respiratory insufficiency due to neuromuscular or chest wall dysfunction. However, little attention has been paid to the effects of long-term ventilation on spontaneous breathing during sleep in such patients. The purpose of this study was to determine wheth...
