With a time lag of no more than 2 or 3 breathing cycles phrenic nerve activity decreased with elastic unloading to a new level. It decreased in a hyperbolic relation to the percentually scaled improvement in Ctot, both before (r=0.85) and after (r=0.69) lung injury. We conclude that ...
Summated flow of impulses from all SAPR investigated stood in a non-linear relationship to lung volume during normal breathing. Reasons for the different relationships between the activity rate of individual SAPR and lung volume during normal pulmonary ventilation and during inflation of the lungs are...
Respiratory mechanical data were derived from esophageal pressure and airflow in eight anesthetized, intubated, spontaneously breathing cats. Dif- ferent C, levels were set on the ventilator both before and after lung injury with xanthine osidase. 'I'he difference (mean 1.4 f 2 SD) between 21.4...
Symptoms:While many people with stage 2 hypertension might still not experience symptoms, those who do might notice headaches, vision problems, chest pain, difficulty breathing, irregular heartbeat, and fatigue. Dangers:Stage 2 hypertension significantly elevates the risk of cardiovascular diseases like ...
I held her hand and watched her breathing. When sometimes she would pause for long seconds between breaths, I resisted the urge to shake her.Not yet! I’m not ready. It wasn’t supposed to happen like this. It’s hard to explain. All I did was complain about her, I know, so I ...
With the prior art devices, the patient must entrain his or her breathing rate to that of the device. However, failure of entrainment poses the risk of stimulated glottal opening during voice production or swallowing, leading to interruption of speech or inhalation of food. In contrast, the ...
When at sea level and breathing room air, the partial pressure of O_2 in inspired air is a. 760 mm Hg b. 40 mm Hg c. 100 mm Hg d. 160 mm Hg e. 150 mm Hg Aortic blood pressure is highest during: a. Atrial systol...
