Amkay Pulse Oximeter (PHX-PO-03) — Uses, Dosage & Benefits

A fingertip pulse oximeter uses photoplethysmography: it emits red and infrared light through the finger and measures the light absorbed by oxygenated and deoxygenated hemoglobin. The device calculates SpO2 percentage and pulse rate from these absorption patterns and pulse wave signals.

Insert 2 AAA batteries (if required) as per manual. Place the device on a clean, warm finger (usually index or middle) with the nail facing up; keep the hand still at heart level. Wait for a stable reading (typically 10–30 seconds) and record SpO2 and pulse rate; remove after use. Not affected by food; avoid use with nail polish/false nails, cold fingers, excessive movement, or bright ambient light for best accuracy.

Always follow your doctor's prescription. Do not self-medicate.
