Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
329
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,...

Oxygen Delivering System I: Nasal Cannula and Face Mask
242
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:...

Oxygen Delivering System III: Tracheostomy and T-piece
467
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Suctioning the Oropharyngeal Airway
179
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Administering Oxygen by Nasal Cannula
376
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.
