Overview
Screening
- Screening among patients with altitude sickness include:[1]
- Cold pressor test
- Put one hand above the wrist for 1 min in ice water (4-5°C)
- Measuring blood pressure on the opposite arm at 15 seconds intervals
- Difference between peak and basal blood pressures determines the level of vascular reactivity
- Heart rate variability
- Participants resting in supine position and wear a chest strap from a heart-rate monitor watch
- After 5 minutes rest period, heart rate is collected on a beat-by-beat basis for 10 minutes
- Pulmonary function test
- Measure flow-volume loop, maximal voluntary ventilation, forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and peak expiratory flow
- Cold pressor test
