Section 1: Safety Precautions

Cincinnati Sub-Zero Products, LLC, reserves the right to make changes to the device, which may not be reflected in this
manual.

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, 32.2°C,

37.8°C or 43.3°C to a patient-applied air-distribution device. The settings are termed “Fan Only”, “Low”, “Medium” and
“High”, respectively.

Indications for Use

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.

Safety Precautions WarmAir Model 135 Manual

Warnings

 A Licensed Healthcare Practitioner's order is required for setting temperature and use of equipment.

At least every 20 minutes, or as directed by a Licensed Healthcare Practitioner, check the patient's
temperature and skin condition of areas in contact with the disposable blanket. Pediatric and
temperature-sensitive patients should be checked more frequently. Notify the Licensed Healthcare
Practitioner promptly of any change in order to avoid serious injury.

 Patient temperature depends on ambient temperature and additional sheets or blankets. Reduce or

discontinue therapy when therapeutic goal is reached or if vital signs instability occurs. Thermal
injury may result. Notify Licensed Healthcare Practitioner immediately of vital signs instability.

 Do not use the WarmAir



135 unit distal to arterial cross clamping. Thermal injury may result.

 Do not use the WarmAir



135 unit along with High Frequency surgical instruments or endocardial

catheters. Electrical shock, thermal injury or electromagnetic interference may result.

Notify the Licensed Healthcare Practitioner promptly if any of the following occur:

 If the patient's temperature is not responding properly,
 If the patient's temperature does not reach the prescribed temperature in the prescribed time, or
 If there is a change in the prescribed temperature range. Failure to inform the Licensed Healthcare

Practitioner of the deviation may result in injury to the patient.

 The warming of transdermal medications (patches) can increase drug delivery, resulting in possible

injury to the patient.

 Do not use the WarmAir



Model 135 unit with any blanket or warming cover other than CSZ

FilteredFlo Blankets or the Warming Tube. Thermal injury may result.

 Do not attempt to warm patient without a blanket, i.e. with the hose only. Thermal injury may result.

 Unapproved modifications may cause patient/caregiver injury and/or equipment damage.

 Do not continue therapy if either the Over-Temperature or Under-Temperature warning light activates

or the audible alarm sounds. Do not continue therapy if power cannot be maintained to the unit.
Thermal injury may result. Turn the unit off and remove from service.

 Do not initiate therapy unless the WarmAir



135 unit is securely mounted or injury may result.

 Always unplug the unit before accessing internal components during service. Failure to unplug the

unit could result in electric shock.

 Do not by-pass ground lug. Electrical Hazards may result.

 The use of materials of good thermal conductivity, such as water, gel and similar substances, with the

WarmAir135 unit not switched on, can decrease the body temperature of a patient.

 Thermal injury may occur if heating therapy is applied to ischemic limbs.

 Do not use the WarmAir



135 unit in the presence of flammable anesthetics. Risk of explosion may

result.

 The WarmAir



135 unit disposables (FilteredFlo Blankets, Warming Tube) are not sterile and are
intended for single patient use only. DO NOT sterilize or reprocess these disposables. Thermal injury
and/or cross-contamination may result.

 Do not allow the hose to contact the patient. Thermal injury may result.

 Do not return the WarmAir



135 unit to service without the filter present. Thermal injury may

result.

 Do not use the WarmAir



135 unit without the designated filter in place. Thermal injury or airborne

contamination may result.

 Electrical shock hazard. To avoid risk of electrical shock, disconnect power before servicing.

 To avoid the risk of electric shock, this equipment must only be connected to a supply mains with

protective earth.
