“…Noise exposure during H-CPAP may be attenuated by positioning heat-moisture exchange filters on the inspiratory limb [ 87 ]. Other tools proposed to decrease patients’ perceived noise include earplugs, sound traps and tubes with smooth inner surfaces [ 84 , 85 ] and avoiding unnecessarily high flows.…”

A helmet, comprising a transparent hood and a soft collar, surrounding the patient’s head can be used to deliver noninvasive ventilatory support, both as continuous positive airway pressure and noninvasive positive pressure ventilation (NPPV), the latter providing active support for inspiration. In this review, we summarize the technical aspects relevant to this device, particularly how to prevent CO2 rebreathing and improve patient–ventilator synchrony during NPPV. Clinical studies describe the application of helmets in cardiogenic pulmonary oedema, pneumonia, COVID-19, postextubation and immune suppression. A section is dedicated to paediatric use. In summary, helmet therapy can be used safely and effectively to provide NIV during hypoxemic respiratory failure, improving oxygenation and possibly leading to better patient-centred outcomes than other interfaces.

“…Several investigations reveal that the stressful environment in Neonatal Intensive Care Units (NICUs) causes premature infants functional disorders [3,4]. High noise levels not only contribute to neonatal hearing loss [5][6][7][8] but also affect physiological factors: reduction in mean blood pressure [9], increased heart rate (HR) and respiratory rhythm, and decreased oxygen saturation (O-sat) [10] as well as neonates' ability to self-regulate [11]. The mid-to-long-term effects of repeated stimulation by high-intensity sounds have also been shown to influence psychological factors, and therefore, they could have significant repercussions on newborn behavior [5,[12][13][14].…”

Background: It is known that high noise levels can be harmful to preterm infants, causing physiological and psychological disorders. It is also known that premature babies spend a lot of time in an incubator. In this sense, many studies show that incubator noise levels can range from 45 to 70 dB. However, these differences in noise levels depend, fundamentally, on the wide range of methodology that can be used. This study aims to know the levels of noise from a fan in the incubator itself and how much it can isolate the noises coming from the outside. Methods: For this purpose, the noise levels of three incubators were measured within a sound-dampened booth for free-field audiometry. For the emission of acoustic energy, a pink noise generator was used; likewise, two microphones were placed, one inside the incubator cabin and the other outside, to determine the acoustic insulation levels of the tested incubators. Results: The incubators produced equivalent continuous sound pressure levels between 53.5 and 58 dB. Acoustic insulation analysis showed that levels varied from one incubator to another, between 5.2 and 10.4 dB. Conclusions: It is necessary to improve the acoustic insulation inside the incubator cabin and to reduce the noise levels of the motor fan. On the other hand, although the incubators are meeting the noise criteria set out in the IEC60601-2-19: 2009 standard of 60 dBA, under normal use conditions, they are still far from the limit recommended by the American Academy of Pediatrics (45 dBA).

“…One of the techniques is helmet CPAP. [2][3][4][5][6][7] Helmet CPAP is a device delivering positive pressure without invasive methods and it is more comfortable than mask. It is stable, allow longer use and has less complications than the mask.…”

A 59 yrs old male with severe ARDS due to COVID-19 infection was in life threatening ‘cytokine storm’. He had also co-morbids including diabetes mellitus and hypertension. He had come from Grobogan, a red area for COVID-19. Clinical finding indicted systemic inflammatory response syndrome (SIRS) with dyspnea, tachycardia, and high fever. Laboratory tests showed raised leukocyte count, CRP, SGOT/SGPT, blood sugar, PCT, low PaO2/FiO2 ratio. RT PCR showed he was infected by COVID-19. Sputum culture showed Klebsiella infection and CXR showed bilateral pneumonia. Patient was treated with standard therapy and a combination of tocilizumab for cytokine-storm and helmet CPAP for severe ARDS. Helmet CPAP has become the first modality for COVID-19 ARDS in some countries but not in Indonesia. We chose helmet CPAP because of the cost efficient, comfortable, and easy operation compared to other modality. We chose tocilizumab because it uses a single dose. Although it is expensive, only one dose is enough and it is effective in blocking the cytokine storm. We found that helmet CPAP and tocilizumab combination in COVID-19 lead severe ARDS could be promising to prevent intubation for patients. Key words: Helmet CPAP; ARDS; COVID-19; Tocilizumab; Cytokine storm Citation: Permana SA, Sugiarto A, Thamrin MH, Arifin, Harsini.
