Can anxiety affect oxygen levels?

Asked By: quantumSoup Date created: May 15, 2022

Background: Stress and anxiety alter respiratory rate and thereby alter oxygen saturation in the blood. Management of psychological stress in the dental office may help maintain blood gas homeostasis. One method of stress management is through the use of preoperative oral sedation.

How does depth affect dissolved oxygen?

Asked By: Rahul Shukla Date created: May 13, 2022

DISSOLVED OXYGEN SATURATION DO saturation also declines with depth (Fig. 3). The highest dissolved oxygen levels tend to be at the surface because oxygen concentrations are higher in the atmosphere and most mixing occurs at the surface through diffusion.

Does oxygen level affect heart rate?

Asked By: enxaneta Date created: May 07, 2022

A decrease in oxygen saturation and increases in pulse rate and heart rate variability were found to be associated with ambient concentration of fine particles. A heart rate acceleration may well result either from impairment of autonomic nervous cardiac control or in response to hypoxia.
