| | Supplemental oxygen therapy is one of the most prescribed and effective therapies for patients emerging from the influences of surgery and anesthesia while in the PACU. | | | Hypoxemia continues to be a relatively common complication in the immediate and extended period after surgery and anesthesia. | | | In one study, recovery personnel were unable to detect hypoxemia 95% of the time when they were blinded to the pulse oximeter reading.10 Although supplemental oxygen therapy is effective in alleviating postoperative hypoxemia,8,13,14 it is not a guarantee of adequate oxygenation. |

| | Preview: The role of long-term oxygen therapy for hypoxemia in patients with chronic obstructive pulmonary disease is well established. | | | The classic description of hypoxemia was put forth in 1875 by Tissandier in regard to his accidental rise to 24,600 feet in a high-altitude balloon: "The condition of torpor that overcomes us is extraordinary. | | | The transtracheal oxygen approach is often successful in patients who have refractory hypoxemia to oxygen delivered by nasal cannula. |

| | In the group with hypoxemia, hemoptysis was present in two patients, clubbing of the digits in one and bilateral basal interstitial changes in chest radiographs in two, while no clinical findings were observed in the normoxemic group. | | | This group of five patients with hypoxemia (two men and three women; mean age 56 years) was compared with the remaining group of 26 patients without hypoxemia (16 men and 10 women; mean age 50 years). | | | Surprisingly, one hypoxemic patient in this study had a negative contrast-ECHO.In the literature, it is stated that pulmonary hypertension should be excluded in hypoxemia cases with negative contrast ECHO findings [30] but the in the patient in our study, there was no clinical or laboratory finding suggesting pulmonary hypertension. |

| | Most post cardiac surgery hypoxemia is caused by this pathophysiology. | | | Under normal physiologic conditions, a patient's pulmonary capillary flow (perfusion), is matched, or goes to, alveoli with good ventilation. | | | Whether or not the hypoxemia is solely due to alveolar hypoventilation can be determined by utilizing the relationship between pAO2 and paCO2 in the "alveolar gas equation", which states: |

| | Long-term oxygen therapy benefits patients with COPD and other chronic pulmonary diseases with hypoxemia as it increases their survival and quality of life. | | | At the outset it should be determined whether the hypoxemia can be relieved by oxygen therapy alone or it needs oxygen and ventilatory intervention. | | | The aim of oxygen therapy at home is to make the patient active and encourage exercise and other activities outside the home. |

| | Changes in cGMP during hypoxemia or hemodilution were examined using a two-way repeated measures ANOVA, with values before and after the intervention (hypoxemia, hemodilution, or control) treated as the repeated measure. | | | There is evidence that arterial or arteriolar endothelium or smooth muscle can "sense" luminal oxygen tension directly, and at least a portion of the response may involve NO release (for review, see Pearce, 1995). | | | These findings in combination argue that, contrary to the situation with hypoxemia, NO is not involved in the flow increase observed during hemodilution. |

| | With this in mind, it is difficult to justify the common practice of screening for desaturation or treating this group of patients with nocturnal supplemental oxygen. | | | The literature on patients with continuous hypoxemia and COPD firmly supports the use of supplemental oxygen to improve survival. | | | In patients with borderline hypoxemia (Pa > 60 mm Hg), the medical literature is much less clear in terms of improvement in function. |

| | When daytime normoxia is present, but sleep-related hypoxemia has been established by continuous nocturnal monitoring of oxygen saturation, oxygen can be prescribed during the hours of sleep when there is clinical evidence of harm from the consequences of hypoxemia, i.e., morning headaches, clinical evidence of pulmonary hypertension and erythrocytosis. | | | The answer may lie in the fact that the consequences of chronic hypoxemia are not just cardiovascular, hematologic and renal in origin. | | | Similarly, if exercise-related hypoxemia is demonstrated by pulse oximetry, ambulatory oxygen can be prescribed and is particularly appropriate if it can be demonstrated those improved exercise-tolerance results are from ambulatory oxygen therapy |

| | The blood flows from the right side of the heart to the left side because the pulmonic stenosis increases resistance to blood flow out of the right ventricle to a point that it is greater than systemic vascular resistance. | | | As an example, one of our patients with tetralogy of Fallot had an arterial oxygen tension of 33 mmHg on room air. | | | Because of the profound hypoxemia in patients with symptomatic tetralogy of Fallot, polycythemia is a common sequela. |

| | Persistent pulmonary hypertension of the newborn is a cardiopulmonary disorder characterized by systemic arterial hypoxemia secondary to elevated pulmonary vascular resistance with resultant shunting of pulmonary blood flow to the systemic circulation. | | | However, this gradient may not be present if substantial shunting is present at the level of the foramen ovale. | | | With high vascular resistance and the subsequent hypoxemia, myocardial performance may become extremely compromised resulting in right heart dilation, tricuspid insufficiency, and right heart failure. |
