Controlled Oxygen Therapy in Respiratory Failure

Controlled Oxygen Therapy in Respiratory Failure.

Controlled oxygen therapy and pulmonary heart failure.

One hundred and sixty-six episodes of pulmonary heart failure were treated in 40 patients with chronic bronchitis. The natural history of the disease is described when controlled oxygen is the principal therapy. Only eight episodes of heart failure required intermittent positive pressure ventilation. Despite careful attention to the details of the controlled oxygen technique the long-term survi...

Effect of controlled oxygen therapy on arterial blood gases in acute respiratory failure.

Seven patients in acute exacerbation of chronic respiratory failure were given 24.5% and later 28% oxygen through Ventimasks. The mean increases in arterial PO(2) were 11 and 21 mm. Hg while breathing 24.5% and 28% oxygen respectively compared with control values while breathing air. Associated increases in arterial PCO(2) were 4 and 8 mm. Hg, respectively. In five of the patients these increas...

High-flow oxygen therapy in acute respiratory failure.

OBJECTIVE To compare the comfort of oxygen therapy via high-flow nasal cannula (HFNC) versus via conventional face mask in patients with acute respiratory failure. Acute respiratory failure was defined as blood oxygen saturation < 96% while receiving a fraction of inspired oxygen > or = 0.50 via face mask. METHODS Oxygen was first humidified with a bubble humidifier and delivered via face mas...

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...
