NIV device: While CPAP is delivered using a continuous flow, BPAP is typically produced using 2 modes: Spontaneous or spontaneous/timed (S/T). Spontaneous mode is where the machine augments the patient's spontaneous breaths, whereas S/T mode includes a backup rate slightly below the patient's...
Initial prescription for single-circuit bi-level ventilation for de novo ARI: quick rise time (~ 200 ms); high trigger; low cycle; expiratory positive airway pressure (EPAP) 8–12 cm H20; and minimal pressure support (inspiratory positive airway pressure, IPAP ≤ 5 cm H20 above EPAP)...
The first, designated the shield, is made of translucent material and has an ergonomic design based on those employed in conventional CPAP masks. However, the Wolf Mask prototype separates the exhalation and inhalation flow functionalities, as observed in many diving masks. Communication with the ...
Oxygen can be delivered by simple face masks or nasal cannula, the latter being the preferred device as it allows eating and talking without major hindrance. Domiciliary long-term oxygen therapy (LTOT) is recommended in patients with chronic respiratory diseases and severe hypoxemia. The relief of...
