Objectives Breathing cold air can lead to bronchoconstriction and peripheral vasoconstriction, both of which could impact muscular performance by affecting metabolic demands during exercise. Successful solutions dealing with these physiological changes during exercise in the cold has been lacking; therefore, we investigated the influence of a heat and moisture exchange mask during exercise in t...

OBJECTIVE To compare the effectiveness of nasal continuous positive airway pressure delivered by Nasal mask vs Nasal prongs with respect to continuous positive airway pressure failure. STUDY DESIGN Randomized, controlled, open label, trial. SETTING Tertiary care level III neonatal unit. PARTICIPANTS 118 preterm infants-gestational age (27-34 weeks) requiring nasal continuous positive airw...

The helmet, a transparent latex-free polyvinyl chloride cylinder linked by a metallic ring to a soft collar that seals the helmet around the neck, has been recently proposed as an effective alternative to conventional face mask to deliver pressure support ventilation (PSV) during noninvasive ventilation in patients with acute respiratory failure. We tested the hypothesis that mechanical charact...

Thirty-one consecutive patients with respiratory failure in whom treatment with intubation and mechanical ventilation was being strongly considered received alternative ventilatory support by means of a BiPAP ventilatory support system and nasal mask. Laboratory measurements and physical findings were documented before and 1 h after initiation of support. This support improved patient comfort, ...

Here we present the case of a 64 year old female with a history of neck radiation and Reinke’s edema that experienced unexpected respiratory failure after a sedation anesthetic. After the case terminated, the patient was noted to be hypoventilating and stridorous. Mask ventilation, laryngeal mask airway ventilation, and direct laryngoscopy failed. The patient was intubated with video laryngosco...

handling. No easy, definitive, and affordable test can demonstrate effectiveness before each use. Wearers may find the mask uncomfortable. We encourage innovation to improve respiratory protection options. Future studies must be conducted to determine levels of protection achieved when naive users, following instructions, produce a similar mask from identical or similar raw materials. Research ...
