Just answering the door, with her thirty-foot length of oxygen tubing trailing after her, had left her winded.
However, although the value of 100 to 200 μm is widely cited (Fidler et al., 2002; Gray et al., 1953; Tannock, 1968; Brown & Giaccia, 1998; Thomlinson & Gray, 1955), we know of no direct measurements of the diffusion length of oxygen in living tissue.
Pairwise correlation among the SaO2%, clinical score, length of oxygen supply, demographic data and hospitalization were assessed using Spearman's rank test (Rho).
Severity was then analyzed as nominal variables using for clinical score, length of oxygen supplementation and hospitalization the 50th percentile, and for SaO2% the significant hypoxemia threshold of 92%.
The clinical score, length of oxygen supplementation and duration of hospitalization were significantly correlated to each other: score and duration of oxygen supplementation (Rho = 0.482, p<0.0001); score and length of hospitalization (Rho = 0.393, p<0.0001); duration of oxygen supplementation and hospitalization (Rho = 0.527, p<0.0001).
Secondary outcomes include transfer to tertiary institution, admission to intensive care, length of stay, length of oxygen treatment, need for non-invasive/invasive ventilation, intubation, adverse events, and cost.
None of the associations improved by additionally including other variables, such as e.g. length or duration of oxygen.
The FICare program addresses all these issues because it can potentially improve infant outcomes, decrease parental stress and anxiety, and reduce resource use including duration of oxygen therapy and length of hospital stay with potential per diem cost savings.
The low-density plasma radius was calculated to be in the range of 30 to 50 nm corresponding well to the diffusion length of singlet oxygen being less than 50 nm [ 36] in cells.
Duration of oxygen administration after inclusion (2.3 ± 4.3 days) and hospital length of stay after inclusion (5.7 ± 5.3 days).
The whole length of the oxygen-sensitive part of the probe was at least 2 mm inside the tumour throughout the measurements to prevent contamination from room-air O2.
