Myocardial Mysteries
Represents ventricular depolarization on ECG
What is the QRS complex?
The difference between systolic blood pressure and diastolic blood pressure
What is pulse pressure?
The range indicating a normal pH
What is 7.35-7.45
Sedative medications that are used to treat seizure activity but also contribute to critical care delirium
What are benzodiazapines?
Characterized by disregulated immune response and widespread vasodilation unresponsive to fluid resuscitation
What is septic shock?
In this heart rhythm Atropine is unlikely to be effective; you will also see consistent PR interval
What is a second degree Type II AV block (Mobitz II)?
The amount of blood pumped by the ventricles each minute
What is cardiac output?
This interpretation describes the following ABG:
pH 7.30, PaCO2 56, PaO2 77, HCO3 23
What is un-compensated respiratory acidosis?
Considered a medical emergency when above 20mmHg
What is increased intracranial pressure?
Biochemical marker used to evaluate and guide treatment for septic shock
What is lactate?
This life-threatening arrhythmia is characterized by no identifiable QRS complexes, and requires immediate defibrillation
What is ventricular fibrillation?
A normal central-venous oxygen saturation (ScvO2) level
What is 65-75% (will accept 60-80%)?
Normal SvO₂ value (true "mixed venous" sample obtained from PA cath) is 60-80%
It is slightly lower than ScvO₂ because it includes venous return from the coronary sinus (very deoxygenated blood)
When a patient with ARDS is ventilated with FiO2 1.0 and low oxygen saturation you should consider this intervention
what is pronation therapy?
(would also accept nitric oxide therapy)
Mannitol is classified as this type of medication
What is an osmotic diuretic?
This class of medications are powerful anti-inflammatories; a side effect includes high blood glucose levels
What are glucocorticoids/corticosteroids - will accept steroids
e.g. Prednisone, Dexamethasone, Prednisolone
This narrow-complex rhythm may respond to vagal maneuvers, rate is often between 150–250 bpm
What is SVT?
when the upstroke of the square wave test appears slurred and diminished
What is an overdamped arterial line waveform?
Ordered as 100mcg IV push for transient hypotension
What is Phenylephrine?
The tool used in ICU to assess for critical care delerium
What is CAM-ICU?
In cardiogenic shock, this medication should be considered to increase cardiac output
What is an inotrope (e.g. Dobutamine, Milrinone)
This anti-arrythmic medication requires a filter to administer and monitoring of the QTi
What is Amiodarone?
When Levophed has been titrated up to 15-20mcg/min, consider adding this medication
What is Vasopressin?
In compliant, healthy lungs the value might be 10; in ARDS lungs, it might be as high as 30
What is plateau pressure?
The area of injury appears like a crescent moon shape on CT head
What is a subdural hematoma/hemorrhage?
A patient with suspected/confirmed sepsis should be started on antibiotics within this time frame
What is ASAP or within 1 hour of recognition?
