Steve, for your sake I sincerely hope that public health services are better in Bahia Blanca than they are in GBA. My brother-in-law has no private insurance and had a TIA (a brief stroke) last week. He's in a large, "modern" facility in San Martin. Much of his care --- bathing for example --- is expected to be done by the family. But bring your own towels as none are provided. Nor are toilet paper, drinking water for the patient, a pillow(!), etc. Although this is a huge hospital, covering an entire city block, he had to be taken elsewhere for an MRI because their's doesn't work. In the past, my wife has had to bring surgical supplies for even simple procedures.
My daughter had a baby last April, using Swiss Medical. The difference in the care she received and what my brother-in-law is experiencing is extreme. Getting appointments and routine tests maybe be easy for you. Hopefully your care in a life-threatening situation will be up to private health standards.
