What is the primary purpose of ventilation? - correct answer To maintain homeostasis and maintain adequate gas exchange and Acid Base balance What are the physiological objectives of Mechanical Ventilation? (3) - correct answer 1. Support or manipulate pulmonary gas exchange ~ Alveolar ventilation ~ Alveolar Oxygenation 2. Increase lung volume ~Atelectasis - treat/prevent ~ Maintain/restore FRC 3. Reduce WOB clinical objectives of mechanical ventilation (8) - correct answer ...

What is spontaneous ventilation? - correct answer movement of air into and out of the lungs What is respiration? - correct answer exchange of oxygen and carbon dioxide between a organisms and its environment What are the two components of respiration? - correct answer -external respiration -internal respiration What is external respiration? - correct answer exchange of O2 and CO2 between the alveoli & pulmonary capillaries What is internal respiration? - correct answer movement of o...

Calculate the static effective compliance during the delivery of a ventilator breath with 650 mL with a Pplat of 28 cm H2O and a PEEP of 0. Group of answer choices 0.23 L/cmH2O 23 mL/cmH2O Inadequate information provided 0.4 cmH2O/L - correct answer 650/(28-0) = 23 mL/cmH2O When the PIP is 43 cm H2O and the Pplat is 18 cm H2O, how much pressure is required to overcome the resistance of the airways? Group of answer choices 0.25 cmH2O 20 cmH2O 25 cmH2O 15 cmH2O - correct answer 43-18 ...

Chapter.1 The pressure difference between the alveolus (Palv) and the body surface (Pbs) is called A. Transpulmonary pressure B. Transrespiratory pressure C. Transairway pressure D. Transthoracic pressure - correct answer D. Transthoracic pressure Define elastance.: A. Ability of a structure to stretch B. Ability of a structure to return to its natural shape after stretching C. Ability of a structure to stretch and remain in that position D. None of the above - correct answer B. Ab...

What are the physiological objectives of mechanical ventilation? - correct answer 1. Support or manipulate pulmonary gas exchange -Achieve eucapnic ventilation or allow permissive hypercapnia and maintain adequate oxygenation and oxygen delivery 2. Increase lung volume Prevent or reverse atelectasis with adequate PEEP to restore the FRC 3. Reduce the work of breathing -It shouldn't be more work to breathe with a ventilator than it is to breathe without one. What are the clinical obj...

When can ventilation be discontinued? - correct answer after the need for ventilation is resolved About ____% of patients requiring temporary mechanical ventilation do not require weaning - correct answer 80% What is weaning? - correct answer gradual reduction of ventilatory support from a patient who's condition is improving Ventilatory support should be discontinued how soon to avoid risks associated with mechanical ventilation? - correct answer as soon as possible What are four f...

Convert 5 mm Hg to cm H2O. (1 mm Hg x 1.36 cm H2O=) - correct answer 6.8 cm H2O. 1 mm Hg = ___ cm H2O - correct answer 1.36 cm H2O. The pressure difference between the alveolus and the body surface is? - correct answer (Pw) Transthoracic pressure. The pressure difference between the alveoli and the pleural space is? - correct answer (Pl) Transpulmonary pressure. The pressure difference between the airway opening and the alveolus is? - correct answer (Paw) Transairway pressure. Th...

Minute Ventilation (VE) - correct answer Men = 4 × BSA Women = 3.5 × BSA -Increases: By 5% every degree above 99F by 10% every degree above 37C, 20% for metabolic acidosis, 50%-100% if resting energy expenditure is equally increased- Decreases: 10% per degree celsius between 35 and 37C IBW Equation - correct answer Men IBW (lbs) = 106 + 6(H − 60) Women: IBW (lbs) = 105 + 5(H − 60) Remember, adult lungs do NOT - correct answer get larger as he or she gains weight V...

The primary variable that the ventilator manipulates to cause inspiration - correct answer Control variable Control variables - correct answer Volume Pressure Flow Time In what mode is controlling minute ventilation less stable? - correct answer pressure controlled modes In what mode will you see higher mean airway pressures? - correct answer pressure controlled modes Flow triggered, pressure- targeted, time-cycled - correct answer Assisted breath—because flow initiates (patient...

(A/C) Assist/Control mode does what? - correct answer Ventilator does all the work and controls the breath (Vt, V, It) (VC, PC, PRVC) Assist/control mode is _________________ cycled. - correct answer Time (SIMV) Synchronized Intermittent Mandatory Ventilation mode doeswhat? - correct answer Shared work between the patient and the ventilator. (V, P, PRVC) (Spont) Spontaneous ventilation is what? - correct answer Lisa's definition: Pt does all the work and controls the breath (Vt...
