Oxygen Administration by Nasal Catheter

Prospective randomized trial comparing oxygen administration during nasal flexible bronchoscopy : oral vs nasal delivery.

STUDY OBJECTIVES To determine the optimal method of delivering supplemental oxygen during flexible bronchoscopy (FB). DESIGN Prospective study. SETTING University medical center. PATIENTS Ninety-seven consecutive patients undergoing outpatient nasal FB during a 7-month period. INTERVENTION During FB, delivery of oxygen was alternated weekly and administered by nasal cannula either nasal...

High-flow oxygen administration by nasal cannula for adult and perinatal patients.

The nasal cannula has been a commonly used patient interface to provide supplemental oxygen since its introduction in the 1940s. Traditionally, it has been categorized as a low-flow device and capable of delivering a 0.4 F(IO(2)) with flows up to 6 L/min to adults with normal minute ventilation. However, there is considerable performance variability among patients and design, which results in a...

Transtracheal oxygen therapy: an effective and safe alternative to nasal oxygen administration.

Transtracheal oxygen therapy (TTOT) improves the efficiency of oxygen delivery and overcomes the discomfort associated with nasal oxygen delivery in patients on long-term oxygen therapy (LTOT). In addition, TTOT improves compliance and quality of life, and may reduce morbidity. Experience with TTOT in Europe is, however, scarce and the safety of TTOT has not yet been completely determined. Thes...

Effect of nasal cannula oxygen administration on oxygen concentration at facial and adjacent landmarks.

An oxygen-enriched atmosphere enhances the potential for operating-room fires. We thus determined oxygen concentrations at various facial landmarks during oxygen administration via nasal cannulae. Thirteen supine volunteers were draped similarly to patients undergoing a cervical-node biopsy. Oxygen was delivered in random order through nasal cannulae at rates of 2, 4, and 6 l x min(-1). Oxygen ...
