My husbands grandfather was in the hospital today..and when the took his pulseox it was 95 - his breathing was labored- and noted as labored by the triage nurse, and upon listening to his lungs he was found to be congested. All throughout nursing school I have been told that a pulseox below 98 requires oxygen, all of my instructers, and even some nurses that I have dealt with in a clinical setting have ensured me that this is the case. Am I wrong?? Of course I am a nurse, however - I am willing to accept if I have been misinformed. Thanks =)
