Randomized Controlled Trial Comparative Study
A Pilot Study Comparing Two Oxygen Delivery Methods for Patients' Comfort and Administration of Oxygen.
The traditional oxygen delivery methods for oxygen therapy are continuous flow oxygen (CFO) and demand oxygen delivery (DOD); however, oxygen waste is considerable in CFO, while DOD is uncomfortable for patients. Synchronized DOD (SDOD), which was designed to overcome the drawbacks of both CFO and DOD, supplies oxygen according to the patient's breathing pattern and the desired oxygen saving. This study was conducted to examine the overall performance of SDOD in terms of oxygen saturation (SpO2 ), patients' comfort, and oxygen saving ratio (SR). ⋯ SDOD appears to be more suitable for oxygen therapy than CFO when considering SpO2 , patients' comfort, and SR.
