2.1m Disposable Sampling Cannula Nasal Oxygen Cannula CO2+O2 Free Breathing Cannula

2.1m Disposable CO2+O2 Sampling Cannula Free Breathing 

A 2.1m disposable sampling cannula is a type of nasal oxygen cannula used for sampling or collecting respiratory gases, such as oxygen (O2) and carbon dioxide (CO2), during medical procedures or diagnostic tests. Here's an overview of its features:

Design: The sampling cannula is designed with two prongs that are inserted into the patient's nostrils. The prongs are typically made of soft and flexible materials to ensure patient comfort.

Length: The sampling cannula is approximately 2.1 meters (around 7 feet) long. This length allows for adequate reach and flexibility during procedures or tests, ensuring ease of movement for the patient.

Sampling Capabilities: The cannula is specifically designed for sampling respiratory gases, including oxygen and carbon dioxide. It is used to

collect a representative sample of the patient's exhaled gases for analysis or monitoring purposes.

Disposable: The sampling cannula is disposable, meaning it is intended for single-use only. This helps maintain hygiene, prevent cross-contamination, and ensure accurate and reliable gas sampling results.

The 2.1m disposable sampling cannula, also known as a CO2+O2 free breathing cannula, is commonly used in various medical settings such as hospitals, clinics, and research laboratories. It is frequently employed during procedures like pulmonary function testing, capnography, and other respiratory assessments.

It's important to follow the instructions provided by healthcare professionals for the proper insertion and usage of the sampling cannula. They will guide you on how to position the prongs within the nostrils to ensure accurate gas sampling and minimize discomfort for the patient.

What is a CO2 nasal cannula?

A CO2 nasal cannula, also known as a capnography cannula or end-tidal CO2 sampling cannula, is a device used to monitor the levels of carbon dioxide (CO2) in a patient's exhaled breath. It is specifically designed to measure the end-tidal CO2 (EtCO2) levels, which is the concentration of CO2 at the end of exhalation.

The CO2 nasal cannula is similar in design to a standard nasal cannula used for oxygen delivery but has an additional port or sampling line attached to it. This port allows for the collection of a small sample of exhaled breath, which is then analyzed to determine the CO2 concentration.

The cannula is typically placed in the patient's nostrils, with the sampling line connected to a capnography monitor or analyzer. As the patient breathes, a small amount of exhaled breath is diverted through the sampling line, and the capnography monitor measures the CO2 levels in real-time.

Capnography, which is the measurement and graphical display of CO2 concentration over time, is commonly used in various clinical settings, including anesthesia, intensive care units (ICUs), emergency departments, and respiratory therapy. It provides valuable information about a patient's respiratory status, helps assess ventilation, and aids in the diagnosis and management of certain respiratory conditions.

CO2 nasal cannulas are usually disposable and come in different sizes to accommodate different patients, from infants to adults. They are designed to be comfortable and non-invasive, allowing for continuous CO2 monitoring during the patient's normal breathing.

Does high-flow nasal cannula help CO2?
Yes, high-flow nasal cannula (HFNC) therapy can help with the removal of carbon dioxide (CO2) from a patient's respiratory system. HFNC delivers a high flow of heated and humidified oxygen through nasal prongs, providing several benefits that can aid in CO2 elimination.

Washout effect: The high flow of oxygen delivered by the HFNC system creates a washout effect, meaning it flushes out the exhaled CO2 from the nasopharyngeal dead space. This reduces the amount of CO2 that is rebreathed and helps maintain lower CO2 levels.

Increased alveolar ventilation: HFNC can enhance alveolar ventilation, which is the process of exchanging oxygen and CO2 in the lungs. The high flow rate of oxygen helps to flush out the CO2 present in the alveoli, leading to improved gas exchange.

Positive end-expiratory pressure (PEEP) effect: HFNC therapy provides a certain level of positive pressure during exhalation. This PEEP effect helps keep the airways open, improves lung compliance, and reduces the risk of airway collapse. By keeping the airways open, it facilitates more efficient removal of CO2.

Reduction in work of breathing: HFNC can reduce the work of breathing for patients by providing a continuous flow of oxygen, reducing the effort required to inhale. This can help patients maintain adequate ventilation and minimize CO2 retention.

It's important to note that while HFNC therapy can assist in CO2 removal, it may not be sufficient for patients with severe respiratory distress or those requiring more aggressive ventilation support. In such cases, other interventions, such as non-invasive positive pressure ventilation (NIPPV) or invasive mechanical ventilation, may be necessary.
