Abstract:
Non-drug treatments such as long term oxygen therapy (LTOT) and non-invasive positive pressure ventilation (NPPV) are thought important for patients with chronic obstructive pulmonary disease (COPD). It is reported that LTOT can improve the prognosis of patients with COPD, particularly who have severe respiratory failure. NPPV attracted attention to avoid endotracheal intubation and high efficacy in patients with acute exacerbation of COPD. In chronic phase of COPD, NPPV may improve the quality of life in patients with hypercapnia, selected carefully.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
