Key result
Vital capacity measurement was evaluated as an objective criterion to guide the initiation and weaning of respirator use in patients with poliomyelitis.
Why the study?
Does the measurement of vital capacity indicate the spontaneous breathing ability and need for a respirator in patients with poliomyelitis?
Observational
Does the measurement of vital capacity indicate the spontaneous breathing ability and need for a respirator in patients with poliomyelitis?
Vital capacity has been proposed as a measure to guide respirator use in poliomyelitis, though objective data supporting specific thresholds has historically been lacking.
Answers are grounded in this paper and cite their sources.
Vital capacity may guide respirator decisions in poliomyelitis; leaves open prospective validation of thresholds before clinical adoption.
THERE has long been a need for a simple objective criterion to indicate when use of a respirator should be started during the acute illness of poliomyelitis and to guide the weaning of patients with respiratory-muscle paralysis from respirators. Some authors1 , 2 have used the vital capacity during the acute illness to indicate when patients should be placed in a respirator. They presented no objective data for the statement that patients should be placed in tank respirators when the vital capacity was 25 per cent of the predicted value. Affeldt3 measured the vital capacity at intervals during periods of unassisted breathing . . .

Ferris et al. (1955) conducted an observational in Poliomyelitis. Vital capacity measurement was evaluated on Spontaneous breathing ability and need for a respirator. Vital capacity measurement was evaluated as an objective criterion to guide the initiation and weaning of respirator use in patients with poliomyelitis.
