Medical High Flow Nasal Cannula flow Nasal Cannula Adult Without
humidifier
Product description
A high-flow nasal cannula (HFNC) is a medical device used to
deliver a high flow of heated and humidified oxygen-enriched air to
patients with respiratory issues. It consists of a nasal cannula
connected to an air-oxygen blender, a heated humidifier, and a flow
meter.
HFNC therapy offers several advantages over traditional oxygen
therapy methods, such as:
- Comfort: The warm and humidified air reduces nasal discomfort and
dryness, making it more comfortable for patients compared to
standard oxygen delivery systems.
- High Flow Rates: HFNC can deliver oxygen at higher flow rates than
conventional oxygen therapy, providing better oxygenation and CO2
washout.
- Improved Oxygenation: The high flow of oxygen-enriched air can
improve oxygenation in patients with respiratory distress or
hypoxemia.
- Reduced Work of Breathing: HFNC can decrease the work of breathing
by providing constant positive airway pressure, making it easier
for patients to breathe.
- Temperature and Humidity Control: The ability to control the
temperature and humidity of the delivered air helps prevent airway
drying and irritation.
- Reduced Risk of Complications: HFNC therapy may reduce the risk of
complications such as nosocomial infections and
ventilator-associated pneumonia.
- Easy Adaptation: Patients find it easier to tolerate HFNC therapy
due to its non-invasive nature and comfortable delivery of oxygen.
HFNC is commonly used in various clinical settings, including
intensive care units (ICUs), emergency departments, post-anesthesia
care units, and for patients with acute respiratory failure or
chronic respiratory conditions. It is essential to monitor patients
closely while using HFNC to ensure appropriate oxygenation levels
and to adjust settings as needed based on clinical response.
Application
- Acute Respiratory Distress Syndrome (ARDS): HFNC is often used in
the management of ARDS to improve oxygenation and reduce the work
of breathing in critically ill patients.
- Chronic Obstructive Pulmonary Disease (COPD): HFNC therapy can be
beneficial for patients with COPD exacerbations by providing
high-flow oxygen and reducing respiratory distress.
- Pneumonia: HFNC is utilized in patients with pneumonia to support
oxygenation and ventilation, particularly in cases where
conventional oxygen therapy may be insufficient.
- Postoperative Care: HFNC is employed in postoperative care to
manage respiratory complications, aid in weaning off mechanical
ventilation, and enhance postoperative oxygenation.
- Pediatric Care: HFNC is commonly used in pediatric settings to
treat respiratory distress in infants and children, providing
effective oxygen therapy with improved comfort and tolerance.
- Heart Failure: Patients with acute decompensated heart failure may
benefit from HFNC therapy to improve oxygenation and alleviate
respiratory distress.
- Neuromuscular Disorders: HFNC can be helpful for patients with
neuromuscular disorders who have difficulty with breathing,
providing respiratory support and oxygenation.
- Sleep Apnea: In some cases of sleep apnea, HFNC therapy can help
maintain airway patency and improve oxygen levels during sleep.
- Emergency Departments: HFNC is used in emergency departments to
provide rapid and effective oxygen therapy to patients presenting
with respiratory distress or hypoxemia.
- Home Care: HFNC can be utilized in home care settings for patients
requiring long-term oxygen therapy, offering a comfortable and
efficient means of oxygen delivery outside of the hospital
environment.
FAQ
1.What is a high-flow nasal cannula used for?
A high-flow nasal cannula accomplishes a reduction of
nasopharyngeal airway resistance, leading to improved ventilation
and oxygenation through the application of a positive pressure
environment.
2.What is the difference between a high-flow nasal cannula and a
regular cannula?
High-flow nasal cannulas deliver warm oxygen. It can deliver up to
about 60 liters of oxygen per minute. It delivers warm oxygen
because oxygen at this flow rate could dry up your nasal passages
quickly and lead to nosebleeds. Low-flow nasal cannulas don't
deliver warm oxygen.
3.What is the highest flow rate for nasal cannula?
The high-flow nasal cannula (HFNC) delivers oxygen at rates that
exceed a person's flow demands (up to 60 L/min), and delivers
positive pressure for lung recruitment and the establishment of
alveolar ventilation.
4.What is the difference between high-flow and low flow?
Thus, if the ventilatory demand of the patient is met completely by
the system, then it is a high-flow system. In contrast, if the
system fails to meet the ventilatory demand of the patient, then it
is classified as a low-flow system.
5.Which patient should not use the high-flow nasal cannula?
Contraindications. Critically ill infants and children requiring
immediate higher level of respiratory support i.e. NIV or invasive
ventilation or decreased level of consciousness.
6.What are the benefits of high-flow oxygen?
When compared to traditional oxygen therapy, delivered through a
face mask, high flow continuous oxygen therapy offers: Better
clearance of fluids (secretions) due to humidified air. Better
tolerated and more comfortable. Easier to communicate during
therapy.
