[Current guidelines for oxygen therapy in emergency care]
Abstract:
Hypoxemia can cause damage to any tissue in the human body. Tissue hypoxia is a condition in which oxygen (O2) delivery to the tissues does not meet their metabolic needs. The major goal in the treatment of patients with hypoxemic acute respiratory failure (ARF) is to ensure normal oxygenation of the body. The leading therapy option for ARF is the use of O2. The paper gives the basic principles of emergency O2 therapy: indications, treatment goals, monitoring guidelines, methods for delivery of O2, and measures to prevent its toxic effects.

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:
Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue, improving...
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,...
Respiratory Assessment: Purpose and Indications
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
