Partial Weight

The oxygen consumption of human adipose tissue (AT) was determined in 53 adults, lean and obese, and in nine lean boys. The oxygen consumption was positively related to fat cell weight and negatively to age and degree of obesity. Men and women did not differ with respect to oxygen consumption of AT. The positive relationship between oxygen consumption per cell and fat cell size was also demonstrated in size-separated cells from the same donors. Expressed per cell the oxygen consumption was higher in fat cells from obese than in cells from lean subjects, but expressed per gram of tissue the opposite result was found. The oxygen consumption of the total AT organ was higher in obese than in lean subjects. The energy expenditure of AT constituted approximately 4% of the estimated 24-h energy expenditure in both groups. It is concluded that obese subjects do not maintain their obesity because of a reduced energy expenditure of the total AT (or of the total body). After a partial weight reduction in five subjects, the energy metabolism tended to change in direction toward the conditions seen in lean subjects. However, it is still an open question whether the observed energy metabolic aberrations of obese human AT are only secondary to the obese state or partly primary and thus of etiological importance.

Professor Burmeister, in dealing with problems of relative growth, uses equations of the form Y = a Xh, as proposed by Huxley. Values for the exponent b, in equations of this form, indicate the rate of accretion of the part (organ, chemical constituent, body compartment, metabolic function) in relation to the whole. Values for b of less than one indicate a relatively lesser rate of accretion of the part See Images in the PDF File e.g., our exponent for extracellular fluid, b = 0.80 (Table II of Burmeister's reference 5); values of greater than one indicate a relatively greater rate of accretion of the part–e.g., Burmeister's exponents for total body potassium, 1.09, and for cell mass, 1.11, and ours for resting oxygen consumption, 1.22, and for fat, 2.18 (Table II of Burmeister's reference 5).

Preoxygenation allows a margin of safety prior to establishing control of a patient’s airway. Effective preoxygenation is influenced by careful technique, respiratory physiology, blood oxygen content, and total body oxygen consumption. Total body oxygen consumption is increased in the pregnant, pediatric, and obese populations, making maintenance of oxygenation more difficult during apnea. In addition to a standard facemask, advanced equipment such as high-flow nasal cannula, THRIVE, and various mask variants may be used. Positioning of a patient for advanced airway management affects preoxygenation, respiratory mechanics, and the conditions for establishing a definitive airway. The “triple airway support” maneuver consists of head extension, neck flexion, and protrusion of the mandibular teeth over the upper teeth; and provides effective mechanics for positive-pressure mask ventilation. Patients with potentially unstable cervical spines present additional challenges and, especially in emergency situations, require careful negotiation of priorities. Common maneuvers such as head tilt, jaw thrust, cricoid pressure, and manual in-line stabilization can cause motion in the unstable cervical spine with uncertain effects.  This review contains 7 figures, 5 tables, and 43 references. Keywords: preoxygenation, functional residual capacity, blood oxygen content, alveolar fraction of oxygen, total body oxygen consumption, high-flow nasal cannula, apneic oxygenation, sniffing position, triple airway support maneuver, manual in-line stabilization

The oxygen consumption and spontaneous activity of A2G ( hr/+), A2G ( hr/hr) and NMRI mice in groups of 2, 3, or 5 were measured, and body fat content was also determined. Average rates of oxygen consumption were found to be lowest in the A2G ( hr/+) and highest in the A2G ( hr/hr) mice, and conversely for the proportion of total body fat. There was no difference in activity of A2G ( hr/+) and A2G ( hr/hr), but the NMRI mice were more active.
