まとめ
高流量鼻カニューレ(HFNC)酸素療法は、従来の酸素療法(COT)と比較して、Prolonged upper GI endoscopy 中の低酸素血症を大幅に軽減しました。 HFNC は、延長された内視鏡処置のためのより安全な酸素供給方法です。
科学分野:
- 消化器病学
- 肺医学
- 集中治療医学
背景:
- 補助酸素は上部消化管内視鏡検査の標準です。
- Prolonged proceduresに最適な酸素供給方法は不明のままです。
- 高流量鼻カニューレ(HFNC)酸素療法は、従来の酸素療法(COT)の代替となる可能性があります。
研究 の 目的:
- Prolonged upper GI endoscopy(20分超)を受ける患者に対するHFNCとCOTの評価。
- Prolonged procedures中の軽度低酸素血症(SpO2 < 90%)の発生率の評価。
主な方法:
- オーストラリアの三次病院での前向きランダム化比較試験。
- 患者はHFNC(60 L/分)またはCOT(2 L/分)にランダム化されました。
- 主要評価項目:SpO2 < 90%の発生率。
主要な成果:
- HFNCはCOT(0% vs 20%、P < .002)と比較して低酸素血症(SpO2 < 90%)の発生率を有意に低下させました。
- HFNC群の患者はSpO2≤94%を経験する患者が少なかった(5% vs 51%)。
- 両群間で有害事象に有意差は認められませんでした。
結論:
- HFNC酸素療法は、Prolonged upper GI endoscopy における低酸素血症を効果的に軽減します。
- HFNCは、これらの処置におけるCOTの安全で効果的な代替手段です。
- さらなる研究により、Prolonged endoscopic proceduresの好ましい方法としてHFNCが支持される可能性があります。

Administering Oxygen by Nasal Cannula
3.3K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.

Oxygen Delivering System I: Nasal Cannula and Face Mask
1.7K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
628
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...

Gene Therapy
27.6K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Oxygen Transport in the Blood
6.7K
Hemoglobin (Hb) is a crucial molecule in the human body, consisting of four polypeptide chains, each bound to an iron-containing heme group. This unique structure enables hemoglobin to bind to oxygen, with each molecule capable of combining with four molecules of oxygen, leading to rapid and reversible oxygen loading. When fully loaded with oxygen, it is called oxyhemoglobin, while hemoglobin that has released oxygen is called reduced hemoglobin or deoxyhemoglobin. As hemoglobin binds oxygen,...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
2.4K
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
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,...
