<unk> -flow<unk>  is useful in patients that are spontaneously breathing but have an increased work of breathing. Conditions such as general respiratory failure, asthma exacerbation, COPD exacerbation, bronchiolitis, pneumonia, and congestive heart failure are all possible situations where<unk> -flow<unk>  may be indicated. HHHF has been used in spontaneously breathing patients with during general anaesthesia to facilitate surgery for airway obstruction. Newborn babies<unk> -flow<unk>  has shown to be useful in neonatal intensive care settings for premature infants with Infant respiratory distress syndrome, as it prevents many infants from needing artificial ventilation via intubation, and allows safe respiratory management at lower FiO2 levels, and thus reduces the risk of retinopathy of prematurity and oxygen toxicity. Due to the decreased stress of effort needed to breathe, the neonatal body is able to spend more time utilizing metabolic efforts elsewhere, which causes decreased days on a mechanical ventilator, faster weight gain, and overall decreased hospital stay entirely.<unk> <unk><unk>  has been successfully implemented in infants and older children. The cannula improves the respiratory distress, the oxygen saturation, and the patient's comfort. Its mechanism of action is the application of mild positive airway pressure and lung volume recruitment. Benefits HFT, the clinician can deliver<unk> er FiO2 to the patient than is possible with typical oxygen delivery<unk>  without the use of a non-rebreather mask or tracheal intubation.<unk>  humidification of the respiratory gas facilitates secretion clearance and decreases the development of bronchial hyper-response symptoms. Some patients requiring respiratory support for bronchospasm benefit using air delivered by HFT without additional oxygen. HFT is useful in the treatment of sleep apnea. During use of HFT the patient can speak. As this is a non-invasive<unk> , it avoids the risk of ventilator-associated pneumonia in situations where it can supplant the use of a ventilator. Use of nasal<unk> <unk>  in acute hypoxemic respiratory failure does not affect mortality or length of stay either in hospital or in the intensive care unit. It does however reduce the need for tracheal intubation (by 15%) and escalation of oxygenation and respiratory support. However, the certainty that this result is reliable is low, as different studies were less precise than they could have been. People on nasal<unk> <unk>  feel more comfortable, less breathless, and there was little evidence of harm.
