How to diagnose ARDS?
There's no specific test to identify ARDS. The diagnosis is based on the physical exam, chest X-ray and oxygen levels. It's also important to rule out other diseases and conditions — for example, certain heart problems — that can produce similar symptoms.
What is the first goal of ARDS?
The first goal in treating ARDS is to improve the levels of oxygen in your blood. Without oxygen, your organs can't function properly.
What is the best test for ARDS?
Because the signs and symptoms of ARDS are similar to those of certain heart problems, your doctor may recommend heart tests such as: Electrocardiogram. This painless test tracks the electrical activity in your heart. It involves attaching several wired sensors to your body. Echocardiogram.

What is the best way to treat refractory maternal ventilatory failure?
For severe, refractory cases of maternal ventilatory failure, consultation should take place with maternal-fetal medicine, anesthesia, and neonatology regarding the possible need for urgent delivery or pregnancy termination. The fetus exerts an additional ventilatory demand on the mother that can be alleviated with delivery, but even cesarean births with general anesthesia temporarily increase oxygen consumption.
Why is understanding the normal physiologic circulatory and respiratory changes of pregnancy important?
An understanding of the normal physiologic circulatory and respiratory changes of pregnancy is critical in approaching the critically ill pregnant patient.
What is the normal PCO2 for pregnant women?
CO2 retention — often underrecognized since the normal PCO2 in pregnancy = 30 mmHg. A POC2 of 40, especially when the respiratory rate is high, indicates respiratory failure during pregnancy.
What to do after deep sedation?
After deep sedation, consider muscle relaxation / paralysis to obliterate patient effort and minimize CO2 production.
What factors influence the decision making process of a fetus?
Special considerations of oxygen delivery to the fetus (determined by maternal cardiac output, hemoglobin, and oxygen saturation) and oxygen consumption (driven by metabolic demands of both mother and fetus, and significantly increased during labor or cesarean birth) factor into decision-making in this population.
What is the leading cause of ICU admission for pre-partum pregnant patients?
Respiratory insufficiency is among the leading causes of ICU admission for pre-partum pregnant patients, and accounts for up to 30% of maternal deaths.
What diseases should be considered for patients with respiratory failure and a clear CXR?
For patients with respiratory failure and a clear CXR, in addition to asthma or embolism of clot or amniotic material, one should consider: Neuromuscular disease (myasthenia gravis, multiple sclerosis, post-poliomyelitis syndrome, or amyotrophic lateral sclerosis.
What is the management of ARDS during pregnancy?
Management of the pregnant woman with ARDS needs to take into account the respiratory physiological changes accompany ing pregnancy. Loss of lung volume due to the enlarging uterus is largely offset by widening of the anteroposterior and transverse diameters.
What are the causes of ARDS?
ARDS is produced by a variety of direct and indirect insults to the lung, such as bacterial pneumonia, viral pneumonitis and inhalation injury (direct), as well as sepsis, transfusion-related and pancreatitis (indirect). Direct causes of ARDS involve local damage to the lung epithelium, whereas indirect causes produce lung damage ...

Fetal teratogenicity risks are greatest during first trimester and related to the total dose administered (usually requiring >50 mGy). 33, 34 Carcinogenesis (development of childhood cancer) arises due to DNA mutations which can occur at any radiation dose with no absolute lower safe threshold.
What causes gastric acid aspiration in pregnant women?
24 Contributing factors include increased intra-abdominal pressure, lowering the tone of the esophageal sphincter (due to progesterone), and use of the supine position for delivery.
What is ARDS in medical terms?
Acute respiratory distress syndrome (ARDS) was initially described in adults as a condition sudden in onset associated with bilateral radiographic opacities and severe hypoxemia. 1 Pathology in these patients demonstrated pulmonary edema, alveolar collapse and hyaline membrane involvement of the alveoli that resembled neonate hyaline membrane disease. An earlier American-European Consensus Conference (AECC) definition established criteria of bilateral radiological infiltrates, impaired oxygenation and exclusion of hydrostatic pulmonary edema. This was replaced in 2012 by the Berlin definition that addressed timing of the condition, included criteria for positive end-expiratory pressure (PEEP) and that classified patients into three distinct severity categories according to oxygenation criteria (Table 1). 2 This definition highlights the acute onset of ARDS (within 7 days of the inciting condition) to exclude various chronic conditions, does not require objective measurements to exclude heart failure, and does not include the term “acute lung injury”.
Is oseltamivir used in pregnancy?

What is needed for ARDS?
To relieve shortness of breath and prevent agitation, the ARDS patient usually needs sedation. Sometimes added medications called paralytics are needed up front to help the patient adjust to the ventilator. These medications have significant side effects and their risks and benefits must be continuously monitored.
What is supportive care for ARDS?
The goal of supportive care is getting enough oxygen into the blood and delivered to your body to prevent damage and removing the injury that caused ARDS to develop.
Why do ARDS patients turn over?
When oxygen and ventilator therapies are at high levels and blood oxygen is still low, ARDS patients are sometimes turned over on their stomach to get more oxygen into the blood. This is called proning and may help improve oxygen levels in the blood for a while.
Why do doctors give diuretics for ARDS?
Doctors may give ARDS patients a medication called a diuretic to increase urination in hopes of removing excess fluid from the body to help prevent fluid from building up in the lungs. This must be done carefully, because too much fluid removal can lower blood pressure and lead to kidney problems.

Do you need oxygen for ARDS?
All patients with ARDS will require extra oxygen. Oxygen alone is usually not enough, and high levels of oxygen can also injure the lung. A ventilator is a machine used to open airspaces that have shut down and help with the work of breathing.
What happens to the lung during pregnancy?
During pregnancy, there is more atelectasis, a complete or partial collapse of the lung or part of the lung. There’s a decrease in functional residual capacity, the volume remaining in the lungs following a passive exhalation. All of these changes affect the threshold for intubation and mechanical support for the pregnant patient.
Why does my breath get shallow during pregnancy?

Can pregnant women get ARDS?
Pregnant women who contract the virus could also be more susceptible to acute respiratory distress syndrome (ARDS). ARDS is a common cause of respiratory failure in critically ill patients. Characterized by fluid buildup in the lung’s alveoli, ARDS prevents the lungs from filling with enough air and less oxygen reaches the bloodstream.
Does intubation lead to preterm birth?
Intubation does not need to lead to preterm birth, she said. To minimize harm, the Society for Maternal-Fetal Medicine does not recommend early delivery because there is not enough evidence to show improvement in lung function attained by early birth. 7.
