The Effects of Sa-Am Acupuncture Treatment on Respiratory Physiology Parameters in Amyotrophic Lateral Sclerosis Patients: A Pilot Study

Table 2

The correlation between K-ALSFRS-R score and the difference of EtCO₂,  SpO₂,  RR, and pulse rate before and after acupuncture stimulation.

	EtCO2	SpO2	RR	Pulse
K-ALSFRS-R	0.104	0.046	−0.077	−0.236**

Analyzed by Pearson’s correlation analysis (^∗𝑃<0.05, ^∗∗𝑃<0.01).
EtCO₂: end-tidal carbon dioxide, SpO₂:  saturation of partial pressure arterial oxygen, and RR: respiratory rate.
