Increase in resistance of in-line breathing filters in humidified air.
نویسنده
چکیده
A study has been performed to measure the resistance of Pall Ultipor BB50 filters when exposed to humidified air for 48 h during artificial ventilation by an Engstrom Erica ventilator fitted with a Bennett Cascade Mk2 humidifier. A marked increase in resistance was demonstrated. A hypothesis is presented as to the aetiology of these findings together with details of minor modifications to the system which allow the use of these filters under clinically acceptable conditions.

HY POXIA AND I TS INFLUEN CES ON THE CARDIOVASCULAR AND RESPIRATORY SYSTEMS OF SPONTANEOUSLY BREATHING CATS
Effects of acute systemic hypoxia on the cardiovascular system (CYS) and respiration of spontaneously breathing cats were studied in two conditions. 1): Hypoxic air (6-8% 02 in N2) was given to the animal to induce systemic hypoxia for 20 minutes. Hyperventilation at this condition lowered arterial C02 tension (PaC02 hypocapnia). 2): In the second run, induction of hypocapnia was prevented ...
متن کاملTHE EFFECT OF ARTERIAL O2 SATURATION AND HE ART RATE ON BLOOD PRESSURE DURING HYPOXIA
A periodic increase in blood pressure (BP) occurs during apneic episodes in patients with obstructive sleep apnea (OSA). Several factors including hypoxemia and an increase in heart rate (HR) were reported to be responsible for this increased BP. To examine the contribution of these two factors in increasing BP, 35 healthy male subjects (mean age±SD= 23.64±3.80) were studied in three experi...
متن کاملAirway resistance due to alveolar gas compression measured by barometric plethysmography in mice.
We developed a method for measuring airway resistance (R(aw)) in mice that does not require a measurement of airway flow. An analysis of R(aw) induced by alveolar gas compression showed the following relationship for an animal breathing spontaneously in a closed box: R(aw) = A(bt)V(b)/[V(t) (V(e) + 0.5V(t))]. Here A(bt) is the area under the box pressure-time curve during inspiration or expirat...
متن کاملThe effect of pressure drop on respirator faceseal leakage.
Users of particulate air-purifying respirators are typically told to change their filters when breathing resistance becomes uncomfortable. It has been proposed that a noticeable increase in breathing resistance (pressure drop) may increase airflow through respirator faceseal leaks. This logic has been extended to suggest that respirator user exposure to contaminants may increase because of this...
متن کاملA Numerical Simulation of Inspiratory Airflow in Human Airways during Exercise at Sea Level and at High Altitude
At high altitudes, the air pressure is much lower than it is at sea level and contains fewer oxygen molecules and less oxygen is taken in at each breath. This requires deeper and rapid breathing to get the same amount of oxygen into the blood stream compared to breathing in air at sea level. Exercises increase the oxygen demand and make breathing more difficult at high altitude. In this study, ...
