Final answer:
To monitor Rachael for respiratory depression, her respiratory rate, oxygen saturation level, and carbon dioxide levels in her blood can be monitored.
Step-by-step explanation:
To monitor Rachael for respiratory depression, several methods and parameters can be used. One method is to monitor her respiratory rate by counting the number of breaths she takes per minute. A normal respiratory rate for an adult at rest is typically between 12 and 20 breaths per minute. If Rachael's respiratory rate falls below this range, it may indicate respiratory depression.
Another parameter to monitor is the oxygen saturation level using a pulse oximeter. This device measures the amount of oxygen in the blood. A normal oxygen saturation level is usually above 95%. If Rachael's oxygen saturation level drops below this threshold, it may indicate respiratory depression.
In addition, monitoring the level of carbon dioxide in Rachael's blood can be helpful. This can be done through an arterial blood gas analysis or a capnography measurement. An increase in carbon dioxide levels in the blood may indicate respiratory depression.
