Clark Kent was injured while saving Lois Lane (again). He was on bed rest for two weeks and today is his first day back training with you, his exercise physiologist. You are starting him out with a very light aerobic workout: walk at 67 m/min at a 1.5% grade for 45 minutes. Enter the energy expenditure in terms of VO2 ml/kg/min. Round to the nearest whole number and do not include units in your answer.  Equations:Age predicted maximum heart rate = 220 – age Intensity: Percent of age predicted heart rate maximum = (220 – age) × (% intensity ÷ 100) Heart rate reserve = (HRmax/peak – HRrest) × (% intensity ÷ 100) + HRrest VO2 Reserve = (VO2max/peak – VO2rest) × (% intensity ÷ 100) + VO2rest Metabolic Equations: Walking: VO2 = 3.5 + (0.1 × speed) + (1.8 × speed × grade)​ Jogging: VO2 = 3.5 + (0.2 × speed) + (0.9 × speed × grade)​

True/False: High Intensity Interval training is appropriate for a selected subsection of individuals with heart failure. 

Which one of the following correctly defines the two common classifications of Valvular Heart Disease:​

A mechanically ventilated patient has a PaO2 of 50 mm Hg on an FIO2 of 0.60. The chest radiographs over the past 12 hours show worsening bilateral infiltrates. The patient’s oxygenation status should be managed by using the:

The PaO2 of a mechanically ventilated patient is 50 mm Hg. Which of the following changes is least effective to increase the PaO2?

Female patient with an mPaw of 46 cmH2o, FiO2 75%, PaO2 56 and after PP for 2 hours the mPaw is 32 cmH20, FiO2 75%, and PaO2 is 72. Is the PP working for this patient? 

A 75-kg male patient is receiving mechanical ventilation in SIMV mode and has the following ABGs and vent settings: Vent Settings: VC/SIMV/ Vt 500 mL/RR 16/PEEP +5/ FiO2 35%, the patient is not breathing spontaneously at this time. ABGs: pH 7.29 PaCO2 59 PaO2 75 HCO3 26Which of the following should the RT recommend to correct the ABG at this time?
