Prevent hypotension and hypoxemia

Hypoxemia

تنفس یکی از اساسی ترین نیازهای انسان است که در صورت عدم تأمین این نیاز، حیات انسان چند دقیقه ای بیشتر ادامه نخواهد یافت. اهمیت این فعالیت حیاتی از تأثیر آن بر تغذیه سلولها به عنوان کوچکترین واحد سازنده بدن انسان نشأت می گیرد، زیرا اکسیژن یکی از مواد ضروری برای سلولها می باشد و کسب این ماده حیاتی فقط از طریق تنفس مناسب و راحت امکان پذیر است .

Plasma expanders used to treat or prevent hypotension can themselves cause hypotension.

Endogenous angiotensins and catecholamines do not reduce skin blood flow or prevent hypotension in preterm piglets

Endocrine control of cardiovascular function is probably immature in the preterm infant; thus, it may contribute to the relative ineffectiveness of current adrenergic treatments for preterm cardiovascular compromise. This study aimed to determine the cardiovascular and hormonal responses to stress in the preterm piglet. Piglets were delivered by cesarean section either preterm (97 of 115 days) ...

Blood oxygenation and spurious hypoxemia

In health pO2(a) is maintained within the range 10.613.3 kPa (80-100 mmHg) and hypoxemia (reduced blood oxygen) is diagnosed if pO2(a) is less than 10.6 kPa (80 mmHg). The purpose of this article is to highlight the spurious severe hypoxemia that occurs in patients with particularly high white-cell count or high platelet count. In these patients there is a marked discrepancy between measured (i...
