Looking for a Better Way to Treat Hypoxia in the Emergency Department? Reach for High-Flow Nasal Cannula

HFNC is a better oxygen delivery and respiratory support device than the standard non-rebreather oxygen mask, venturi-mask, and simple low flow nasal cannula in a hypoxic patient. In respiratory distress, a patient’s inspiratory flow and minute ventilation are much higher than the 15 L/min flow of oxygen from a non-rebreather mask. This means with each breath room air is being inhaled along with the supplemental oxygen, ultimately decreasing the total FiO2 being delivered to your patient. HFNC can better match the inspiratory flow and minute ventilation of most patients to deliver a consistent amount of oxygen and less inhaled ambient room air.

Hi-VNI treats symptoms of respiratory distress and is appropriate for patients experiencing high work of breathing, air hunger, hypoxemia and hypercapnia. Patients must be spontaneously breathing, alert and oriented and have the ability to protect their airway.

Stewart County man breathes new life into NICU, COPD treatment

Hope came through the door when a young respiratory therapist/ clinical specialist entered the hospital with a device he claimed to be lifesaving. It was a breathing device called Vapotherm, which he said could deliver oxygen to patients more safely and comfortably than traditional machines.

Change in the air for oxygen delivery

A more comfortable, less expensive approach to high-flow oxygen delivery is likely to gain ground in adult ICUs over the next few years, buoyed by recent research showing somewhat better outcomes and no increased risks compared with current practice.

High-flow nasal cannula therapy for adult patients

Recently, the use of HFNC in treating adult critical illness patients has significantly increased, and it is now being used in many patients with a range of different disease conditions.

High-flow nasal oxygen therapy in intensive care and anaesthesia

The application of HFNO is becoming widespread in Intensive Care Units (ICUs), favoured by increasing evidence based on numerous studies supporting its efficacy.

The First Major NIV Innovation in the Past 30 Years is Here!—And It May Be a Solution for Anxious Respiratory Distress Patients

Let’s face it, tightly strapped face masks are not exactly pleasant. While many respiratory distress patients tolerate mask and pressure-based therapies just fine, many also experience anxiety and claustrophobia. Yet the gold standard treatment for patients in undifferentiated respiratory distress is Noninvasive Positive Pressure Ventilation (NiPPV), even though about a third of all NiPPV failure is due to mask-intolerance. It was about time for an alternative. Let’s face it, tightly strapped face masks are not exactly pleasant.

Vapotherm® vs. BiPAP® – What are the Differences?

NiPPV is considered the gold standard for treating respiratory distress patients, but HVNI is the first major noninvasive ventilation (NIV) innovation in the past 30 years which expands options for practitioners.
