“…13,17,18 Face mask may cause discomfort, induce claustrophobia, and impede oral intake and communication. 19 Nasal mask requires patent nasal passages and mouth closure to minimize leak, and can cause pressure sores and tissue necrosis over the nasal bridge. 20 Collectively, these problems may cause poor adherence to therapy 17 and increased nursing time.…”

OBJECTIVE:In a cardiothoracic and vascular intensive care unit, to compare nasal high-flow (NHF) oxygen therapy and standard high-flow face mask (HFFM) oxygen therapy in patients with mild to moderate hypoxemic respiratory failure. METHODS: In a prospective randomized comparative study, 60 patients with mild to moderate hypoxemic respiratory failure were randomized to receive NHF or HFFM. We analyzed the success of allocated therapy, noninvasive ventilation rate, and oxygenation. RESULTS: Significantly more NHF patients succeeded with their allocated therapy (P ‫؍‬ .006). The rate of noninvasive ventilation in the NHF group was 3/29 (10%), compared with 8/27 (30%) in the HFFM group (P ‫؍‬ .10). The NHF patients also had significantly fewer desaturations (P ‫؍‬ .009). CONCLUSIONS: NHF oxygen therapy may be more effective than HFFM in treating mild to moderate hypoxemic respiratory failure.

“…Some studies have shown that perioperative oxygen delivery reduces wound infection and the incidence of nausea andvomiting as well as hypoxemia (Laurer & Gombkoto 2006). Oxygen is generally delivered to patients via oxygen masks or nasal cannulae (Sasaki et al. 2003).…”

“…However, this study was performed using the OxyArm, in which the diffuser was placed in a plastic boom connected to a headset, and measurements were obtained in healthy volunteers (3). Subsequent work evaluating the diffuser technology used either healthy volunteers, nonoxygendependent patients, or patients with chronic obstructive pulmonary disease of unknown severity, and did not evaluate the diffuser while placed in a face mask (4)(5)(6)8,9). These differences in patient population and interface design may limit the application of earlier findings to patients with chronic, severe respiratory disease.…”

“…We studied this hypothesis by titrating supplemental oxygen in oxygen-dependent patients through an OxyMask and Venturi mask (Hudson RCI, USA) in a randomized, single-blind, cross-over design. Although the diffuser technology has been evaluated previously, this has predominantly been in healthy volunteers (3)(4)(5), in which the diffuser was placed in a plastic boom connected to a headset (OxyArm, Southmedic Inc). Only one previous investigation has used the OxyArm in oxygen-dependent patients (6).…”

BACKGROUND: The OxyMask (Southmedic Inc, Canada) is a new face mask for oxygen delivery that uses a small 'diffuser' to concentrate and direct oxygen toward the mouth and nose. The authors hypothesized that this unique design would enable the OxyMask to deliver oxygen more efficiently than a Venturi mask (Hudson RCI, USA) in patients with chronic hypoxemia. METHODS: Oxygen-dependent patients with chronic, stable respiratory disease were recruited to compare the OxyMask and Venturi mask in a randomized, single-blind, cross-over design. Baseline blood oxygen saturation (SaO 2 ) was established breathing room air, followed in a random order by supplemental oxygen through the OxyMask or Venturi mask. Oxygen delivery was titrated to maintain SaO 2 4% to 5% and 8% to 9% above baseline for two separate 30 min periods of stable breathing. Oxygen flow rate, partial pressure of inspired and expired oxygen (PO 2 ) and carbon dioxide (PCO 2 ), minute ventilation, heart rate, nasal and oral breathing, SaO 2 and transcutaneous PCO 2 were collected continuously. The study was repeated following alterations to the OxyMask design, which improved clearance of carbon dioxide. RESULTS: Thirteen patients, aged 28 to 79 years, were studied initially using the original OxyMask. Oxygen flow rate was lower, inspired PO 2 was higher and expired PO 2 was lower while using the OxyMask. Minute ventilation and inspired and expired PCO 2 were significantly higher while using the OxyMask, whereas transcutaneous PCO 2 , heart rate and the ratio of nasal to oral breathing did not change significantly throughout the study. Following modification of the OxyMask, 13 additional patients, aged 18 to 79 years, were studied using the same protocol. The modified OxyMask provided a higher inspired PO 2 at a lower flow rate, without evidence of carbon dioxide retention. CONCLUSIONS: Oxygen is delivered safely and more efficiently by the OxyMask than by the Venturi mask in stable oxygen-dependent patients.
