OBJECTIVES: The Vapotherm system delivers high humidity to the airway of patients by using semipermeable tubules where heated liquid water is in contact with air. The humidified air is conducted to the patient via a heated tube. Preliminary clinical observations in infants with croup suggested that epinephrine added to the water supplying the humidity was delivered successfully in the vapor phase. The purpose of this study was to evaluate the efficiency of the delivery of epinephrine in the vapor phase and to develop the feasibility criteria for a clinical pilot study...

OBJECTIVE: Heating and humidification of inspired gases is routine during neonatal non-invasive respiratory support. However, little is known about the temperature and humidity delivered to the upper airway. The International Standards Organization (ISO) specifies that for all patients with an artificial airway humidifiers should deliver ≥33 g/m(3) absolute humidity (AH). We assessed the oropharyngeal temperature and humidity during different non-invasive support modes in a neonatal manikin study...

BACKGROUND: Excessive ambient noise levels have been identified as a potential risk factor for adverse outcome in very preterm infants. Noise level measurements for continuous positive airway pressure (CPAP) devices demonstrated that these constantly exceed current recommendations. The use of high-flow nasal cannula (HFNC) as an alternative non-invasive ventilation modality has become more popular in recent years in neonatal care. OBJECTIVE: To study noise levels of two HFNC devices commonly used in newborns...

OBJECTIVE: To determine whether postextubation respiratory support via heated, humidified, high-flow nasal cannulae (HHHFNC) results in a greater proportion of infants younger than 32 weeks' gestation being successfully extubated after a period of endotracheal positive pressure ventilation compared with conventional nasal continuous positive airway pressure (NCPAP). STUDY DESIGN: We randomly assigned preterm ventilated infants to Vapotherm HHHFNC or NCPAP after extubation...

AIM: Heated humidified high-flow nasal cannula (HHHFNC) oxygen is a relatively new form of respiratory support and is increasing in popularity despite lack of supportive evidence and amid safety concerns. We investigated the prevalence of its use in tertiary neonatal units in the UK. METHOD: Electronic survey. RESULTS: A total of 57 units were contacted and replies received from 44 (77%). HHHFNC was used in 34/44 (77%) units. Vapotherm 2000i and Fisher and Paykel RT329 were the most popular devices...

We report a case of a 3-year-old boy who underwent an arterial switch operation with relief of left ventricular outflow tract obstruction and later presented with recurrent episodes of flash pulmonary edema. High-flow humidified oxygen with positive pressure support (Vapotherm) was used as a treatment modality, thereby avoiding intubation and mechanical ventilation.

OBJECTIVES: Use of high-flow humidified nasal cannulas to deliver continuous positive airway pressure in children is increasing. Data on the relationship between the flow values and the corresponding pressures are limited. The purpose of this experiment was to evaluate the relationship between the device, intraprong, and proximal airway pressures and the flow values in a neonatal/pediatric test lung model, using the Vapotherm 2000i and Fisher-Paykel humidified nasal cannulas devices. METHODS: Using a pediatric size cannula (2-mm inner diameter), we measured the device, intraprong, and proximal airway pressures at random flow values between 0 L/min and 12 L/min with an FIO2 of 0...

Neonatal units in the UK are beginning to use Vapotherm as a means of providing respiratory support. This device reportedly allows the delivery of high flows of gas at body temperature with close to 100 per cent relative humidity. Evidence from the literature and from UK neonatal units suggests that Vapotherm may be an effective and well-tolerated method of providing babies with respiratory support. It has a number of advantages over therapies such as nasal continuous positive airway pressure, including a reduction in the number of ventilator days and reduced nasal trauma...

BACKGROUND: Vapotherm 2000i is a non-invasive high-flow respiratory support system used mainly in the treatment of type 1 respiratory failure. It uses a mixture of oxygen and air to deliver a set concentration via nasal cannula (or tracheostomy mask). The advantage of this system is the high humidity achieved using the integral heated water system. The system has been used in neonatal practice as a replacement for conventional continuous positive airway pressure (CPAP) but there is little published research within the adult setting about its use...

We used a high-flow nasal cannula with a patient who required a high fraction of inspired oxygen but could not tolerate a nasal or facial mask. We saw a 92-year-old woman with delirium and dementia in the intensive care unit for multi-lobar pneumonia with severe hypoxemia. Attempts to oxygenate the patient failed because she was unable to tolerate various facial and nasal masks. We then tried a high-flow nasal cannula (Vapotherm 2000i), which she tolerated well, and she had marked improvement in gas exchange and quality of life...

Oxygen is the commonest drug prescribed in hospitals. The inhaled concentration is altered by the administered oxygen flow rate, the characteristics of the delivery device and the patient's respiratory pattern. Using healthy volunteers we measured the inspired oxygen concentration achieved with different devices both at rest and when the breathing pattern of respiratory failure was simulated by binding the subjects' chests until the forced expiratory volume in 1 s was reduced by > 50% and the respiratory rate was > 25 breaths...
