Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

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,...

Administering Oxygen by Mask

Administering Oxygen by Mask

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:

Oxygen Delivering System III: Tracheostomy and T-piece

Oxygen Delivering System III: Tracheostomy and T-piece

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...

Oxygen Delivering System I: Nasal Cannula and Face Mask

Oxygen Delivering System I: Nasal Cannula and Face Mask

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:...

Administering Oxygen by Nasal Cannula

Administering Oxygen by Nasal Cannula

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.
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils, connected...

Tracheostomy Suctioning II: Procedure

Tracheostomy Suctioning II: Procedure

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Area of Science:

Cardiovascular Surgery
Medical Device Innovation
Perfusion Technology

Background:

Emergency oxygenator changes in extracorporeal circulation (ECC) and extracorporeal membrane oxygenation (ECMO) carry significant risks, including patient mortality and permanent injury.
Current procedures for oxygenator exchange are associated with a reported mortality rate of one patient per month in the US.

Purpose of the Study:

To evaluate a novel system and procedure for oxygenator exchange during ECC and ECMO.
To assess the safety, speed, and reproducibility of the new oxygenator change-out method.

Main Methods:

Implementation of a new system featuring two three-way stopcocks integrated into the active ECC line.
Utilizing a pre-primed backup oxygenator and circuit connected via a dedicated port on the stopcocks.
Blood flow diversion to the new oxygenator without interrupting ECC.

Main Results:

Oxygenator change-out was successfully completed by perfusionists in an average of 62.13 +/- 11.12 seconds.
The new system facilitated a rapid and reproducible oxygenator exchange process.
Continuous ECC was maintained throughout the entire change-out procedure.

Conclusions:

The evaluated system and procedure enable fast, safe, and reproducible oxygenator exchange.
This innovation significantly minimizes the risks associated with emergency oxygenator changes during ECC and ECMO.
The procedure ensures uninterrupted extracorporeal circulation, enhancing patient safety.
