General Description of the WarmAir
®
135
The WarmAir
®
135 unit is a small and compact warming unit designed to supply air at temperatures of
ambient, 90°F, 100°F or 110°F to a patient-applied air-distribution device. The settings are termed “Fan
Only”, “Low”, “Medium” and “High”, respectively.
Indications
The WarmAir
®
135 patient warming system is intended to prevent hypothermia and/or reduce cold
discomfort before, during, and after surgical procedures. The thermal regulating system is used to raise a
patient’s temperature and/or maintain a desired patient temperature through convective heat transfer
from the controller to a warm-air-heated blanket. The single-patient use blankets transfer the thermal
energy to adult, pediatric or neonate patients to obtain/maintain normal body temperature. It is intended
for use by appropriately trained healthcare professionals in clinical environments.
Contraindications
High temperature settings to be used with close patient observation when treating patients with the
following conditions:

Significant peripheral vascular disease, occlusive or diabetic in nature.

Low cardiac output.

Marginal cutaneous perfusion.
Do not apply heat to lower extremities during arterial cross-clamping. Thermal injury may occur if heat is
applied to ischemic limbs.
