Predictable oxygen concentrations with the Bird respirator.
IN 1964, Fairley and Britt investigated the adequacy of the air-mix control of ventilators operated from an oxygen source. 1 The mean inspired oxygen percentages were measured at various cycling pressures, and with the Bird Mark 7 ventilator the oxygen levels varied from 51.5 to 96.8 per cent, being highest at low flows and at high cycling pressures. Consequently, these authors recommended that...
متن کاملThe effect of gender and respirator brand on the association of respirator fit with facial dimensions.
This study examined the association of facial dimensions with respirator fit considering the effect of gender and respirator brand. Forty-one subjects (20 white females and 21 white males) participated in the study. Each subject was measured for 12 facial dimensions using anthropometric sliding and spreading calipers and a steel measuring tape. Three quantitative fit tests were conducted with t...
متن کاملOxygen Dissociation Curves of Bird Blood
In a recent review Redfield (1) has called attention to the atypical manner in which the blood of certain birds and fish combines with oxygen. This matter aroused our interest because in such remotely related animals as Urechis (2), the skate (3), four reptiles (4-6), and the dog (7) the form of the oxygen dissociation curve is roughly similar to that of human blood. Accordingly, experiments ha...
متن کاملThe role of oxygen-increased respirator in humans ascending to high altitude
BACKGROUND Acute mountain sickness (AMS) is common for people who live in low altitude areas ascending to the high altitude. Many instruments have been developed to treat mild cases of AMS. However, long-lasting and portable anti-hypoxia equipment for individual is not yet available. METHODS Oxygen-increased respirator (OIR) has been designed to reduce the risk of acute mountain sickness in a...
متن کاملOxygen toxicity during artificial ventilation.
Repeated pulmonary collapse and changes suggestive of a severe alveolar-capillary diffusion defect were observed over a period of 20 days in a patient who was receiving artificial ventilation because of status epilepticus. Profound cyanosis followed attempts to discontinue assisted ventilation. The Bird Mark 8 respirator employed was found to be delivering approximately 90% oxygen on the air-mi...
