Key Points

Question In acutely ill children clinically assessed to require noninvasive respiratory support in a pediatric critical care unit, is first-line use of high-flow nasal cannula therapy (HFNC) noninferior to continuous positive airway pressure (CPAP) in terms of time to liberation from all forms of respiratory support?

Findings In this randomized noninferiority trial of 600 acutely ill children clinically assessed to require noninvasive respiratory support, median time to liberation was 52.9 hours for HFNC vs 47.9 hours for CPAP. The 1-sided 97.5% confidence limit for the hazard ratio was 0.86, falling within the noninferiority margin of 0.75.

Meaning Among acutely ill children clinically assessed to require noninvasive respiratory support in a pediatric critical care unit, HFNC met the criterion for noninferiority compared with CPAP for time to liberation from respiratory support.

Abstract

(Video) Current Topics in Respiratory Care 2017: Noninvasive Respiratory Support - Dean Hess

Importance The optimal first-line mode of noninvasive respiratory support for acutely ill children is not known.

Objective To evaluate the noninferiority of high-flow nasal cannula therapy (HFNC) as the first-line mode of noninvasive respiratory support for acute illness, compared with continuous positive airway pressure (CPAP), for time to liberation from all forms of respiratory support.

Design, Setting, and Participants Pragmatic, multicenter, randomized noninferiority clinical trial conducted in 24 pediatric critical care units in the United Kingdom among 600 acutely ill children aged 0 to 15 years who were clinically assessed to require noninvasive respiratory support, recruited between August 2019 and November 2021, with last follow-up completed in March 2022.

Interventions Patients were randomized 1:1 to commence either HFNC at a flow rate based on patient weight (n = 301) or CPAP of 7 to 8 cm H2O (n = 299).

Main Outcomes and Measures The primary outcome was time from randomization to liberation from respiratory support, defined as the start of a 48-hour period during which a participant was free from all forms of respiratory support (invasive or noninvasive), assessed against a noninferiority margin of an adjusted hazard ratio of 0.75. Seven secondary outcomes were assessed, including mortality at critical care unit discharge, intubation within 48 hours, and use of sedation.

Results Of the 600 randomized children, consent was not obtained for 5 (HFNC: 1; CPAP: 4) and respiratory support was not started in 22 (HFNC: 5; CPAP: 17); 573 children (HFNC: 295; CPAP: 278) were included in the primary analysis (median age, 9 months; 226 girls [39%]). The median time to liberation in the HFNC group was 52.9 hours (95% CI, 46.0-60.9 hours) vs 47.9 hours (95% CI, 40.5-55.7 hours) in the CPAP group (absolute difference, 5.0 hours [95% CI –10.1 to 17.4 hours]; adjusted hazard ratio 1.03 [1-sided 97.5% CI, 0.86-∞]). This met the criterion for noninferiority. Of the 7 prespecified secondary outcomes, 3 were significantly lower in the HFNC group: use of sedation (27.7% vs 37%; adjusted odds ratio, 0.59 [95% CI, 0.39-0.88]); mean duration of critical care stay (5 days vs 7.4 days; adjusted mean difference, −3 days [95% CI, −5.1 to −1 days]); and mean duration of acute hospital stay (13.8 days vs 19.5 days; adjusted mean difference, −7.6 days [95% CI, −13.2 to −1.9 days]). The most common adverse event was nasal trauma (HFNC: 6/295 [2.0%]; CPAP: 18/278 [6.5%]).

Conclusions and Relevance Among acutely ill children clinically assessed to require noninvasive respiratory support in a pediatric critical care unit, HFNC compared with CPAP met the criterion for noninferiority for time to liberation from respiratory support.

    FAQs

    What is the difference between CPAP and HFNC? ›

    HFNC, like CPAP, is a high flow system and is able to generate a positive end expiratory pressure, but unlike CPAP it does not have a valve [9]. HFNC is suggested to reduce the upper airway dead space and resistance [10,11].

    Is CPAP better than high flow oxygen? ›

    Background: Continuous positive airway pressure (CPAP) has been associated with a lower risk of treatment failure than high-flow nasal cannula (HFNC) in pediatric patients with respiratory distress and severe hypoxemia.

    What is the difference between CPAP and Optiflow? ›

    The Airvo 2 is a system to deliver Optiflow Nasal High Flow (NHF) therapy. The Airvo (an NHF system) is a flow-based therapy (you adjust the flow rate for your patient); CPAP is a pressure-based therapy; you set a pressure range for your patient.

    What is HFNC used for? ›

    HFNC may allow patients to cough, mobilize secretions, and be suctioned, if necessary, all benefits that are often difficult to achieve when a patient is on noninvasive positive pressure ventilation (NIPPV).

    Does HFNC provide peep? ›

    A high-flow nasal cannula (HFNC) demonstrably generates PEEP in neonatal and adult populations at lower flows (eg, 2-8 L/min) and higher flows (eg, ≥ 60 L/min). Few studies have demonstrated PEEP generation at the moderate flows (eg, 8-50 L/min) that are used commonly in pediatric patients.

    Can you use a nasal cannula with a CPAP machine? ›

    Why Can't I Use Nasal Cannula on My CPAP Machine? How ... - YouTube

    What is a BiPAP vs CPAP? ›

    Another common breathing device is the continuous positive airway pressure machine, or CPAP. Both deliver air pressure when you breathe in and breathe out. But a BiPAP delivers higher air pressure when you breathe in. The CPAP, on the other hand, delivers the same amount of pressure at all times.

    What is the difference between Airvo and CPAP? ›

    The Airvo (an NHF system) is a flow-based therapy (you adjust the flow rate for your patient); CPAP is a pressure-based therapy; you set a pressure range for your patient. The pressure derived from Optiflow NHF therapy is dynamic, not set, and not constant.

    How does a nasal CPAP mask work? ›

    You wear a mask over your nose or nose and mouth while you sleep. The mask is connected by a hose to a small machine that sits at the side of your bed. The machine pumps air under pressure through the hose and mask and into your airway while you sleep. This helps keep your airway open.

    Is Optiflow a CPAP? ›

    In this report, we describe our experience with the use of the Optiflow™ (Fisher and Paykel Healthcare) Nasal Cannula attached to a regular CPAP device in the setting of chronic CPAP use. This interface consists of a nasal cannula and was originally designed for the delivery of high-flow oxygen therapy.

    What is the difference between Airvo and Optiflow? ›

    In summary, Airvo and Optiflow are both used for the delivery of high flow respiratory air in patients. Where Airvo is typically the mechanical component heating and humifying the air, Optiflow is typically the interface component for the actual delivery of the air.

    What's the difference between high flow and low-flow oxygen? ›

    Low-flow systems often are more comfortable, but the ability to deliver a precise oxygen concentration in various respiratory breathing patterns is limited. A high-flow system can deliver very accurate oxygen concentrations, but is often uncomfortable and obtrusive.

    What is the danger of having too high oxygen flow through the nasal cannula? ›

    The risks of using a nasal cannula include: Abdominal distension. Children or people undergoing anesthesia are at particular risk of abdominal distension, or bloating of the stomach. Other devices that deliver oxygen maintain a higher level of positive airway pressure and carry no risk of distension.

    What are the primary mechanisms of action of high velocity therapy? ›

    Rather than using pressure as a primary mechanism of action, high velocity therapy has a velocity-based mechanism of action which rapidly flushes the upper airway dead space and fills it with a fresh gas reservoir, thereby facilitating alveolar ventilation.

    What are the benefits of high flow nasal prongs? ›

    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.

    Does high flow provide positive pressure? ›

    High-flow nasal cannula oxygen (HFNC) delivers a high flow of heated and humidified oxygen through nasal prongs. It generate positive airway pressure, reduces respiratory dead space, airway resistance, and less frequent interruption of therapy.

    What is the maximum nasal cannula flow rate? ›

    Conventional low-flow devices (e.g., nasal cannula or simple face mask) provide 100% FiO2 at a maximum of 15 liters per minute. Even during quiet breathing, inspiratory flow rates are approximately 30 liters per minute, which exceeds supplemental oxygen flow (3).

    How do you calculate FIO2 from flow rate? ›

    FiO2 = 20% + (4 x oxygen liter flow)

    Breathe Rate – how slow or fast the person is breathing.

    What are the long term effects of using a CPAP machine? ›

    What are the long-term effects of using a CPAP machine?
    • dry or runny nose.
    • sore throat.
    • dry mouth.
    • dry eyes.
    • nasal congestion.
    • nosebleeds.
    • facial irritation.
    • air leaks around the mask.

    Can you wear oxygen and a CPAP at the same time? ›

    If you happen to suffer from COPD or other lung diseases that lower the blood-oxygen count dramatically, you may require oxygen therapy while you sleep as well! Luckily, you can easily connect your oxygen concentrator to your CPAP machine and use them simultaneously.

    What is the oxygen flow rate for CPAP? ›

    BACKGROUND: CPAP is frequently used in prehospital and emergency settings. An air-flow output minimum of 60 L/min and a constant positive pressure are 2 important features for a successful CPAP device.

    What is better than a CPAP machine? ›

    BiPAP, or BiLevel PAP therapy, works in a similar manner as CPAP. Instead of one single pressure, BiPAP uses two pressures – an inhale pressure and a lower exhale pressure. BiPAP is often used as an alternative to CPAP for sleep apnea when patients also present with lung issues, like COPD.

    When is BiPAP better than CPAP? ›

    The CPAP machine is usually used to treat mild to moderate sleep apnea. But depending on the severity of sleep apnea, doctors may recommend a BiPAP machine instead. Patients requiring high levels of CPAP pressure are often more comfortable using BiPAP.

    What are the 3 modes of ventilation systems? ›

    Based on the types of respiratory cycles that are offered to the patient, three basic ventilatory modes can be considered. These are: Assist/Control ventilation (A/C), Pressure Support Ventilation (PSV) and Synchronized Intermittent Mandatory Ventilation (SIMV) with PS, a hybrid mode of the first two.

    Why is CPAP contraindicated in the patient who is not spontaneously breathing? ›

    The following are relative contraindications for CPAP: Uncooperative or extremely anxious patient. Reduced consciousness and inability to protect their airway. Unstable cardiorespiratory status or respiratory arrest.

    How does CPAP improve oxygenation and ventilation? ›

    Mask CPAP works by assisting spontaneous ventilation and gas exchange. By maintaining a continuous positive airway pressure, CPAP recruits closed (atelectatic) alveoli and increases transpulmonary pressure and thus increases functional residual capacity (FRC) resulting in improved oxygenation.

    Is CPAP invasive or noninvasive? ›

    CPAP is Continuous Positive Airway Pressure. It is a type of non-invasive ventilation (NIV) or breathing support.

    Can CPAP cause lung problems? ›

    Yes, Philips CPAP devices can affect your lungs. If your Philips CPAP sleep apnea machine is defective, you could be breathing in toxic gases or debris that can cause many different types of pulmonary diseases, including lung cancer.

    Does CPAP weaken diaphragm? ›

    Some of the physiological effects noted during CPAP are hyperinflation of the lungs, stabilizing and flattening of the diaphragm, and decrease in tidal volume.

    When do you stop using a CPAP machine? ›

    As long as you have sleep apnea, you will continue to need to use CPAP therapy. That being said, you can discontinue the use of your CPAP machine if your sleep apnea becomes cured or enters remission.

    Does BiPAP improve oxygenation? ›

    While CPAP works to improve only oxygenation (hypoxemic respiratory failure), the use of BiPAP improves not only oxygenation but also ventilation with the use of pressure support. There are different types of BiPAP modes.

    Why is Optiflow used? ›

    Nasal high flow oxygen (Optiflow™) is a new alternative as it provides warmed humidified oxygen at high flow, and also has been shown to assist breathing and improve recovery. It is comfortable during use and indeed may be more comfortable than standard (dry) oxygen via a facemask (Hudson type) or nasal prongs.

    Can BiPAP improve lung? ›

    This allows your lungs to more efficiently transport oxygen to your body and remove excess carbon dioxide. Research has shown that for people who have COPD and higher carbon dioxide levels, regular nighttime BiPAP use can improve quality of life and breathlessness, and increase long-term survival.

    What is the difference between Airvo and high flow nasal cannula? ›

    High Flow Nasal Cannula (Airvo, Vapotherm, Optiflow etc) - YouTube

    Why do we use Airvo? ›

    The AIRVO is for the treatment of spontaneously breathing patients who would benefit from receiving high-flow warmed and humidified respiratory gases, including patients who have upper airways bypassed. The oxygen flow may be from 2 - 60L/min depending on the patient interface and the facilities oxygen delivery source.

    What type of ventilation is Airvo? ›

    Airvo is a form of HFNC (High flow nasal cannula oxygen therapy) and is not a mechanical ventilator. generator that delivers warmed and humidifier respiratory gases to spontaneously breathing patients.

    Which oxygen delivery system would you use for the lowest flow of oxygen? ›

    Low-flow systems include: Simple face mask. Non re-breather face mask (mask with oxygen reservoir bag and one-way valves which aims to prevent/reduce room air entrainment) Nasal prongs (low flow)

    Which is better oxygen mask or nasal cannula? ›

    Some patients may prefer using a face mask instead of a cannula, as face masks offer several distinct advantages. Most notably, face masks can provide a consistent flow of oxygen and generally have a higher recommended flow rate than standard nasal cannulas, with flow rates averaging between 6 and 10 litres per minute.

    What are the disadvantages of using a nasal cannula? ›

    Several drawbacks are associated with these devices, which may limit efficacy and tolerance of oxygen delivery. Usually, oxygen is not humidified at low flow, and complaints, especially dry nose, dry throat, and nasal pain, are common.

    What position is best for promoting expansion of the lungs and reducing pressure? ›

    Prone position should allow a better fitting of the lung into the chest wall, reverts the gravity effect along the vertical gradient, and partly relieves the compression of the lungs due to the mediastinum and heart weight (5).

    What is the best flow rate of oxygen for a patient with COPD? ›

    The currently recommended target oxygen tension in exacerbated COPD is about 60–65 mm Hg, which is equivalent to a saturation of approximately 90%–92% (Table). (2) Despite an initial blood oxygen saturation of 94%, this patient's oxygen flow rate was increased from 2 to 4 L/min.

    What is a dangerously low oxygen level? ›

    People should contact a health care provider if their oxygen saturation readings drop below 92%, as it may be a sign of hypoxia, a condition in which not enough oxygen reaches the body's tissues. If blood oxygen saturation levels fall to 88% or lower, seek immediate medical attention, says Dr.

    What is high velocity nasal insufflation? ›

    Abstract. Background: High velocity nasal insufflation (HVNI) is a form of respiratory support that provides flows that are believed to be in excess of a patient's inspiratory and expiratory flows.

    What is the difference between high flow and CPAP? ›

    HFNC, like CPAP, is a high flow system and is able to generate a positive end expiratory pressure, but unlike CPAP it does not have a valve [9]. HFNC is suggested to reduce the upper airway dead space and resistance [10,11].

    What are the 5 mechanisms of action of HFNC? ›

    The mnemonic (HIFLOW) will help one to remember the mechanisms of action, including Heated and humidified, meets Inspiratory demands, increases Functional residual capacity (FRC), Lighter, minimizes Oxygen dilution, and Washout of pharyngeal dead space.

    Does HFNC help ventilation? ›

    High-flow nasal cannula (HFNC) is increasingly being used as an intermediary form of noninvasive support. Studies have shown that HFNC may improve oxygenation and ventilation and reduce work of breathing, breathing frequency, and the need for intubation.

    What is the difference between Airvo and CPAP? ›

    The Airvo (an NHF system) is a flow-based therapy (you adjust the flow rate for your patient); CPAP is a pressure-based therapy; you set a pressure range for your patient. The pressure derived from Optiflow NHF therapy is dynamic, not set, and not constant.

    What is a BiPAP vs CPAP? ›

    Another common breathing device is the continuous positive airway pressure machine, or CPAP. Both deliver air pressure when you breathe in and breathe out. But a BiPAP delivers higher air pressure when you breathe in. The CPAP, on the other hand, delivers the same amount of pressure at all times.

    What is neonatal CPAP? ›

    Continuous Positive Airway Pressure (CPAP) is a means of providing respiratory support to neonates with either upper airway obstruction or respiratory failure. Respiratory failure constitutes either failure of ventilation or failure of lung function.

    How does a nasal CPAP mask work? ›

    You wear a mask over your nose or nose and mouth while you sleep. The mask is connected by a hose to a small machine that sits at the side of your bed. The machine pumps air under pressure through the hose and mask and into your airway while you sleep. This helps keep your airway open.

These are: Assist/Control ventilation (A/C), Pressure Support Ventilation (PSV) and Synchronized Intermittent Mandatory Ventilation (SIMV) with PS, a hybrid mode of the first two.

    Does CPAP deliver oxygen? ›

    The benefits of using a CPAP machine are well-documented. These machines deliver a continuous supply of oxygen to your body as you sleep. By doing so, they help prevent the brief breathing interruptions that are the hallmark of sleep apnea.

    Is CPAP considered life support? ›

    Equipment not considered life sustaining: refrigerator, air conditioner, nebulizer, CPAP machine, wheelchairs or bed confinement.

    How does CPAP improve oxygenation? ›

    Mask CPAP works by assisting spontaneous ventilation and gas exchange. By maintaining a continuous positive airway pressure, CPAP recruits closed (atelectatic) alveoli and increases transpulmonary pressure and thus increases functional residual capacity (FRC) resulting in improved oxygenation.

    Does CPAP increase respiratory rate? ›

    Conclusion: In the short term, CPAP therapy improves oxygen saturation and reduces respiratory rate and dyspnoea significantly in COVID-19 patients.

    What is considered the most effective interface option for delivering CPAP to infants? ›

    Interfaces. Short binasal prongs or nasal masks are the recommended interface when providing CPAP to infants.

    Can CPAP cause lung problems? ›

    Yes, Philips CPAP devices can affect your lungs. If your Philips CPAP sleep apnea machine is defective, you could be breathing in toxic gases or debris that can cause many different types of pulmonary diseases, including lung cancer.

    Does CPAP weaken diaphragm? ›

    Some of the physiological effects noted during CPAP are hyperinflation of the lungs, stabilizing and flattening of the diaphragm, and decrease in tidal volume.

    When do you stop using a CPAP machine? ›

    As long as you have sleep apnea, you will continue to need to use CPAP therapy. That being said, you can discontinue the use of your CPAP machine if your sleep apnea becomes cured or enters remission.
