Monitoring During Exercise testing

SpO2: Use pulse ox on finger, head, or ear. SpO2 should remain >[blank_start]90[blank_end]%. SpO2 < [blank_start]90[blank_end]% or a decrease of [blank_start]4[blank_end] – [blank_start]5[blank_end]% indicates a pulmonary disorder. BP: Systemic or arterial to estimate normal response to exercise. Manual or automatic or indwelling arterial line. HR and ECG: [blank_start]Normal[blank_end] HR 60 – 100. [blank_start]Tachy[blank_end] HR >100. [blank_start]Brady[blank_end] HR <60. [blank_start]Flutter[blank_end] <200. [blank_start]Fibrillation[blank_end] too fast to count. [blank_start]Ventilation[blank_end]: Minute ventilation and RR, VO2 and VCO2 should be monitored.

Between [blank_start]3[blank_end]-[blank_start]5[blank_end] boxes: HR is 60-100 Closer than [blank_start]3[blank_end] boxes: HR is >[blank_start]100[blank_end] Wider than [blank_start]5[blank_end] boxes: HR is <[blank_start]60[blank_end] HR = [blank_start]300[blank_end]/# of large boxes between R waves
