INSRIRED OXYGEN AND OXYGEN TRANSFER DURING ARTIFICIAL VENTILATION FOR RESPIRATORY FAILURE

Oxygen toxicity during artificial ventilation.

Repeated pulmonary collapse and changes suggestive of a severe alveolar-capillary diffusion defect were observed over a period of 20 days in a patient who was receiving artificial ventilation because of status epilepticus. Profound cyanosis followed attempts to discontinue assisted ventilation. The Bird Mark 8 respirator employed was found to be delivering approximately 90% oxygen on the air-mi...

Treatment of chronic respiratory failure in kyphoscoliosis: oxygen or ventilation?

Patients with kyposcoliosis and chronic respiratory insufficiency are treated either with home oxygen therapy or ventilation. Kyphoscoliotic patients demonstrate impaired ventilatory mechanics, consequently ventilation seems to be the treatment of choice. Yet, no randomised controlled trials (CRT) exist to prove it. Most investigators find it difficult to ethically justify a CRT. Therefore, the...

Noninvasive respiratory support for acute respiratory failure-high flow nasal cannula oxygen or non-invasive ventilation?

J Thorac Dis 2015;7(7):1092-1097 www.jthoracdis.com For patients with acute respiratory failure there may be advantages to the avoidance of invasive mechanical ventilation, i.e., ventilation via endotracheal intubation. Indeed, soon after the introduction of invasive mechanical ventilation many complications of positive pressure ventilation were identified (1,2). Some are directly related to th...

High-flow nasal cannula oxygen therapy during hypoxemic respiratory failure.

Oxygen therapy remains the first line intervention in acute hypoxemic respiratory failure. Several medical devices for oxygen therapy, which range from simple nasal cannula to non-rebreathing face masks, have been used in the management of acute hypoxemic respiratory failure.1 The choice of a specific oxygen delivery device is based on the patient’s oxygen requirements in terms of flow and desi...
