Final answer:
Pulse oximetry is used to assess the need for supplemental oxygen, to guide O2 concentration, to confirm central cyanosis, and when PPV is required. It may be utilized during neonatal assessments, such as the Apgar score. Devin's condition suggests Braxton Hicks contractions, not labor.
Step-by-step explanation:
The use of a pulse oximeter is critical in various medical settings for monitoring the oxygen saturation of a patient's blood. The indications for the use of pulse oximetry include:
- To assess the need for supplemental oxygen, especially in cases where the body may not be getting enough oxygen due to conditions such as pulmonary diseases, heart conditions, or in the perioperative setting.
- To guide O2 concentration in the delivery of oxygen therapy, ensuring that patients receive the appropriate level of oxygen.
- To confirm the perception of central cyanosis, which is a bluish discoloration of the skin, indicative of low oxygen levels in the blood.
- When positive pressure ventilation (PPV) is required, to monitor the effectiveness of ventilatory support.
All babies may not necessarily require pulse oximetry; however, it can be a valuable tool for monitoring their health soon after birth, especially in the context of the Apgar score, which assesses a newborn's skin color, among other criteria.
Regarding Devin's situation at 35 weeks of pregnancy, experiencing mild contractions with an intact mucus plug and no cervical dilation indicates that she might be experiencing Braxton Hicks contractions, which are not a sign of imminent labor. Hence, she was advised to return home.
