Oxygen Flow, Inhalant Oxygen Concentration and CO_2 Gas Concentration in Mask at Oxygen Therapy

High-concentration oxygen therapy in COPD.

Comparison of Mask Oxygen Therapy and High-Flow Oxygen Therapy after Cardiopulmonary Bypass in Obese Patients

Background To clarify the efficiency of mask O2 and high-flow O2 (HFO) treatments following cardiopulmonary bypass (CPB) in obese patients. Methods During follow-up, oxygenization parameters including arterial pressure of oxygen (PaO2), peripheral oxygen saturation (SpO2), and arterial partial pressure of carbon dioxide (PaCO2) and physical examination parameters including respiratory rate, h...

Evaluation of adherence to oxygen therapy standards before, during and after oxygen hood administration

Background and Purpose: Oxygen therapy is one of the common treatments for neonates with cardiopulmonary disease. The aim of this study was to evaluate adherence to oxygen therapy standards by nurses before, during and after using oxygen hood. Methods: In this cross-sectional study, 250 cases of nursing care were evaluated before, during and after administration of oxygen hood therapy in pre...

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 ...

Measuring Dissolved Oxygen Concentration in Aquaculture

(DO) is considered the most important water quality variable in fish culture. In the broadest sense, however, dissolved oxygen concentration is no more important than other environmental variables because any factor that is outside the range tolerated by fish can cause stress or death. What makes dissolved oxygen concentration so important in intensive fish culture is the speed with which it ca...
