What are the indications for mechanical ventilation?
What are the indications for mechanical ventilation?
Indications for Mechanical Ventilation
- Bradypnea or apnea with respiratory arrest.
- Acute lung injury and the acute respiratory distress syndrome.
- Tachypnea (respiratory rate >30 breaths per minute)
- Vital capacity less than 15 mL/kg.
- Minute ventilation greater than 10 L/min.
Do you need a ventilator for a pulmonary embolism?
Mechanical ventilation – noninvasive or invasive – is unnecessary in most cases of PE; hypoxemia can usually be readily controlled by oxygen inhalation.
Is pulmonary embolism a complication of mechanical ventilation?
It is very unusual to have patients with PE under mechanical ventilation. It mainly occurs after cardiac arrest or for refractory shock. Positive pressure ventilation may be avoided when possible because it is deleterious by more increasing the RV afterload.
When is pulmonary embolectomy done?
Pulmonary embolectomy is indicated for patients that develop massive or sub-massive PE within 2 months after craniotomy or spinal surgery and patients with intracranial hemorrhage, because thrombolysis is contraindicated in these patients, who have a high risk of re-bleeding.
Which of the following is not an indication for mechanical ventilation?
| Which of the following is not an indication for mechanical ventilation? | |
|---|---|
| a. | Myocardial infarction (MI) |
| b. | Respiratory failure |
| c. | Provide stability of the chest wall after trauma or surgery |
| d. | Brain injury requiring a barbituate-induced coma |
What is an absolute contraindication for initiating mechanical ventilation?
The only absolute contraindication for mechanical ventilation is if it is against the patient’s stated wishes for artificial life-sustaining measures. The only relative contraindication is if non-invasive ventilation is available and its use is expected to resolve the need for mechanical ventilation.
What is the protocol for pulmonary embolism?
Long-term treatment of patients with PE includes anticoagulant therapy for at least 3-6 mo[6]. Whether the treatment should be extended beyond this period depends on the risk of recurrence[6]. In patients with PE due to a treatable or transient risk factor, discontinuation of anticoagulation at 3 mo is recommended[6].
What is a embolectomy used for?
An embolectomy is surgery to remove an embolus from an artery or vein. An embolus is part of a blood clot that broke free. It can travel through your bloodstream and become stuck in another area.
Do you give oxygen in PE?
Treatment goals for pulmonary embolism are to improve oxygenation and cardiac output. Administer supplemental oxygen via nasal cannula or non-rebreather mask to maintain SPO2 above 94 percent. Be aware that reduced blood flow to the lungs may prevent improvement of hypoxia from oxygen administration.
What is pulmonary artery embolectomy?
Pulmonary Embolectomy. A pulmonary embolectomy is the surgical removal of a pulmonary embolism, which is a blockage in an artery in the lungs.
What are the three types of mechanical ventilation?
There are three basic types of whole-house mechanical ventilation, and by understanding each you can choose the best one for you.
- Exhaust-only ventilation. This ventilation type uses a fan to move indoor air out of your home, while outdoor air is drawn in through leaks.
- Supply-only ventilation.
- Balanced ventilation.
What is the difference between pulmonary ventilation and alveolar ventilation?
Solution : Pulmonary ventilation is the volume of air entering into the lungs in unit time whereas alveolar ventilation is the volume of air entering into the alveoli at the same time. The total volume of air of pulmonary ventilation does not enter the alveoli.
