Hypoxemia is defined as a condition where arterial oxygen tension or partial pressure of oxygen (PaO2) is below the normal value, which is typically between 80 and 100 mmHg. Alveolar ventilation is ...
Extract: Serial studies of arterial and alveolar oxygen, carbon dioxide, and nitrogen tensions, arterial pH, and ratios of dead space: tidal volume were made in 24 nondistressed premature infants. By ...
When you breathe, a certain fraction of your air enters the lungs and blood flows through the capillaries. When this ratio is above or below 0.8, you may have ventilation/perfusion (V/Q) mismatch. A V ...
