Mechanical Ventilation And Temperature Regulation Flashcards
Indications for Mechanical ventilation
-failure to ventilate
-failure to oxygenate
Types of mechanical ventilation
Volume-cycled
Pressure cycled
Pressure support
Volume cycled ventilation
Volume is set and pressure varies based volume delivered
Assist control (A/C)
Synchronized intermittent mandatory ventilation (SIMV)
Pressure cycled ventilation
Pressure is set and volume varies based on pressure delivered
-pressure control ventilation (PCV)
Pressure support (PS)
Pressure support
A relatively low Inspiratory pressure is set to aid inspiration. Often lumped into the pressured-cycled category
Complications of Mechanical ventilation
-dysynchrony
-gas trapping
-oxygen toxicity
-decreased cardiac output
-barotrauma
-pneumothorax
-Ventilator-associated lung injury
Ventilator-associated pneumonia
Nontunneled catheters
-used short term
Tunnelled catheter
Used long term
PICC lines
Long term therapies such as cancer treatments
Implanted catheters
Used short term and have an injection port (do not touch it)
Longer term antibiotic treatments
Indications for CCV lines
-inadequate peripheral venous access
Administration of noxious medications (vasopressors, chemotherapy) or any other meds that can cause phelbitis
Hemodynamics monitoring
Extracorporeal therapies
Indications for PACs
-differentiation of cause of shock
-determining mechanisms responsible for pulmonary edema
Diagnosis or detection of pericardial tamponade
Evaluation or diagnosis of intracardiac shunts
Evaluation of pulmonary hypertension
Perioperative and postoperative management of patients with unstable cardiac status
Titration os vasopressor and vasodilator therapy
Contraindications for PAC
-Coagulopathy
-local trauma to sit of insertion
Inability to float PAC into pulmonary artery
Pathologies that cause the need for mechanical ventilation
-paralysis
-asthmatic
-pulmonary edema
-ROSC
Indications for mechanical ventilation
-failure to oxygenate
-failure to ventilate
