Oxygen Delivery Devices
This device is only for short-term use during the transport of a trach patient not requiring ventilatory support
Oxygenator
Over 6L/min of oxygen should be managed by whom?
Respiratory
What respiratory changes occur during pregnancy that may increase the risk of respiratory infections?
What is the most common cause of respiratory distress in newborns? How can it be prevented in high-risk pregnancies?
Respiratory distress syndrome (RDS) is often due to immature lung development. This can be improved with steroid administration for preterm birth, and preventing preterm delivery, if possible.
While an increase in respiration rate may be normal, _____________ is not.
Tachypnea
Which device is used for 1-6L/min of oxygen delivery without humidification?
Nasal cannula
Nursing can increase or wean these two oxygen delivery devices.
Nasal cannula and non-rebreather mask
How does the physiologic change of increased blood volume during pregnant impact respiratory function?
Increased blood volume leads to engorgement of nasal passages/airways, causing congestion and may exacerbate conditions like asthma or sleep apnea.
Name 3 impacts of maternal hypoxia during pregnancy.
Maternal hypoxia may lead to fetal growth restriction (FGR), preterm birth, death, decreased variability of the fetal heart rate on monitoring, decelerations on fetal heart monitoring.
How does maternal anemia affect oxygen management in pregnant patients?
Maternal anemia reduces oxygen-carrying capacity, increasing the risk of hypoxemia and adequate oxygenation to patient and fetus.
Which device is commonly used during maternal/fetal (intrauterine) resuscitation?
Non-rebreather mask
A humidifier is needed at ___L/min
3L/min
Name 3 potential complications of influenza during pregnancy.
Severe illness, hospitalization, preterm labor, preterm birth, low birth weight
Which vaccine can be given between 32-36 weeks gestation to prevent significant respiratory risks to both the pregnant patient & fetus?
Non-rebreather masks request a minimum flow of ____L/min
10L/min
This device can be utilized on PHRU and has a range of 10-70L/min
Heated high-flow (HHF)
Which delivery devices does not require continuous pulse oximetry?
1-6L/min on nasal cannula
How does pregnancy impact the management and treatment of asthma in pregnant patients?
It can exacerbate asthma due to hormone changes and increased oxygen demand. Management includes close monitoring, avoiding triggers, and using asthma medications that are safe during pregnancy.
Name 2 potential risks of COVID-19 infection for the fetus.
Increased risk of preterm birth, low birthweight, fetal growth restriction, decreased oxygenation that, if severe enough, may lead to stillbirth.
Why is it important that patients with sleep apnea continue treatment during pregnancy?
Untreated sleep apnea reduces oxygenation and related complication & increased the risk of hypertension and preeclampsia.
What are the only 2 oxygen delivery devices that cannot be used on PHRU?
Bi-pap and intubation
How often should lung sounds by auscultated?
Q4 hours or as ordered
Your antepartum patient has been hospitalized for 2 weeks due to SROM. She complains of sudden onset shortness of breath and chest pain. What are you concerned is occurring?
Pulmonary embolism due to relative immobilization and hypercoagulability in pregnancy
How do corticosteroids improve fetal lung development in the premature fetus?
Corticosteroids accelerate lung maturity by stimulation of the production of surfactant. This reduces the risk of RDS and intraventricular hemorrhage (IVH), lowering neonatal mortality rates by improving overall lung function.
When can the influenza vaccine be administered during pregnancy?
It is safe to administer during any trimester of pregnancy.
